AGENCY: Federal Communications Commission.

ACTION: Proposed rule.

SUMMARY: In this document, the Commission commences a proceeding to remove regulatory barriers to the use of spectrum for wireless backhaul and other point-to-point and point-to-multipoint communications. This proceeding will surface ways to increase efficient use of spectrum for backhaul, especially by updating regulatory classifications that may not have kept pace with the evolution of converged digital technologies. Providing for the more flexible use of microwave frequencies for backhaul may help promote access to backhaul solutions that are critical to the deployment of wireless broadband and other services. Our proposed rule changes may be particularly beneficial to rural areas, where wireline alternatives may not exist. Our proposed rules should increase opportunities for all users of point-to-point and point-to-multipoint services, while protecting established license holders who are already using these bands. As an initial matter, we believe 750 megahertz in the 13 gigahertz range and below can be made flexibly usable for broadband backhaul.

Summary

Notice of Proposed Rulemaking

Permitting Greater Sharing Between FS Operations in Certain BAS and

CARS Frequencies 1. One way to potentially increase the availability of microwave spectrum would be to allow FS operations to share spectrum in several bands at 13 GHz and below that are currently assigned to BAS and CARS, but not FS. First, we propose to permit FS operations in the 6875-7125

MHz band, which is adjacent to existing FS operations in the 6525-6875

MHz band and well suited for backhaul and other microwave applications.

In particular, we seek comment on sharing between mobile (temporary fixed) operations and fixed operations in the 6875-7125 MHz band where frequency coordination is not as formalized. In light of the additional sharing proposed by this rulemaking, we also seek comment on whether we should make the identification of receive-only sites associated with TV pickup stations mandatory in the 6875-7125 MHz band. 2. Second, we propose to introduce FS systems into the 12700-13200

MHz band. This band is well suited for short to medium length backhaul microwave applications and in fact prior to 1988 was available to certain relocated FS systems. We seek comment on whether introduction of FS operations in this band, with the additional latitude proposed in this proceeding, will have an adverse impact on cable system operations and whether it will have an effect on future use of the spectrum by cable system operators. 3. Both the 6875-7125 MHz and 12700-13200 MHz bands are currently assigned to television pickup, television studio-transmitter links, television relay stations, television translator relay stations, and

CARS. We emphasize that we are not proposing to modify existing licenses and that any new licenses in this band will need to be frequency coordinated with existing licensees. We believe these uses would be compatible with FS operations with use of frequency coordination. The frequency coordination process has been highly successful in allowing maximum utilization of shared bands and eliminating potential interference problems. We therefore propose to require frequency coordination for new FS, BAS, and CARS stations in the 6875-7125 MHz and 12700-13200 MHz bands in accordance with our existing frequency coordination procedures. Commenters that believe that relying on our existing frequency coordination processes would not adequately address all necessary requirements should propose modifications to that process or alternative processes. 4. We seek comment on the best approach to channelization for the various bands under consideration. We note that existing operations in the 6875-7125 MHz and 12700-13200 MHz bands both use 25 megahertz bandwidth channels. We note that this channelization scheme has been in existence for over 40 years. Existing BAS operations in the 12700-13200

MHz band also use 25 MHz bandwidth channels, while CARS operations in the band use 25 MHz, 12.5 MHz and 6 MHz channels. We seek comment on a channelization scheme that would likewise provide applicants with a variety of channel widths to maximize flexibility and utilization of the 6875-

Page 52187

7125 MHz and 12700-13200 MHz bands. Consistent with our recent action allowing 30 megahertz channels in the Upper 6 GHz Band, we seek comment on alternative channelization schemes. In addition, we propose to facilitate use of the 6875-7125 MHz and 12700-13200 MHz bands by BAS operators by making additional channel bandwidths available for their use. Such action would provide BAS licensees with additional flexibility and provide additional opportunities for using modern digital equipment. 5. With respect to the remaining proposed technical rules for FS operation, we propose to apply the same technical parameters that currently apply to the Upper 6 GHz band to the adjacent 6875-7125 MHz band, because those bands are contiguous and should be able to use similar equipment. We believe that applying the rules currently applicable to the Upper 6 GHz Band to the 6875-7125 MHz band will facilitate equipment development and provide consistency to FS licensees. The specific rules that we propose are: (1) Applying a maximum frequency tolerance of 0.005 percent; (2) applying a maximum transmitter power of +55 dBw; (3) applying the antenna standards currently applicable to Upper 6 GHz Band stations authorized after June 1, 1997 to the 6875-7125 MHz band; (4) applying the capacity and loading requirements contained in Sec. 101.141(a)(3) of the

Commission's rules to this band; and, (5) confirming that the 17 kilometer minimum path length requirement of Sec. 101.143 of the

Commission's rules would apply in the 6875-7125 MHz band. We propose to retain the rules that are already applicable to the 12700-13000 MHz band, with one exception. There is no minimum payload capacity applicable to the 12700-13200 MHz band. We propose to apply the minimum payload capacity and loading requirements that are currently applicable to the 11 GHz band to the 12700-13200 MHz band. We seek comment on these proposals and any possible alternatives to them. We also seek comment on any special technical rules that might be necessary in that band.

Eliminating Final Link Rule 6. While broadcasters are allowed to obtain private fixed service licenses under part 101 of the Commission's Rules, Sec. 101.603(a)(7) prohibits broadcasters from using part 101 stations as the final radiofrequency (RF) link in the chain of distribution of the program material to broadcast stations. In light of recent technological and regulatory developments, we believe that the ``final link'' rule may no longer serve a useful purpose and, in fact, may inhibit the full use of part 101 spectrum. As broadcasters and other microwave users move to digital-based systems, we question whether it makes sense to maintain regulatory restrictions based on the type of content that the digital data transmitted by the system represents. As BAS and CARS move to digital and the technical rules have converged with those in part 101, it has become difficult to distinguish video content from any other digital content or to distinguish a microwave link used for BAS and

CARS from those licensed under part 101. 7. Retaining the ``final link'' rule appears to be spectrally inefficient and places an unnecessary burden on broadcasters. Retaining the ``final link'' rule could force broadcasters to build unnecessarily redundant systems in the same locations: One system using reserved BAS frequencies for the sole purpose of delivering programming to a transmitter site and a second system using FS frequencies for other purposes. Especially in view of the increased sharing of BAS bands with

FS stations we propose above, we believe it is appropriate to provide broadcasters with additional flexibility to use the FS bands. 8. We do not believe that eliminating the final link rule will crowd other FS licensees out of the band. Other rules require all FS licensees, including broadcasters, to build out their spectrum promptly and to comply with minimum payload capacities. These requirements serve to ensure productive use of the spectrum and to prevent noneconomic overuse. 9. Accordingly, we seek comment on eliminating the ``final link'' rule. In considering this proposal, we encourage broadcasters to provide specific data on the efficiencies and cost savings that could result from eliminating this rule. FS licensees who oppose this change should identify the harms they believe would be caused by eliminating this rule and explain why they believe other rules are insufficient to prevent those harms. We also seek comment on whether there are alternatives that could facilitate broadcaster access to FS spectrum while retaining that prohibition under certain circumstances.

Permitting Adaptive Modulation 10. The part 101 rules contain a minimum payload capacity rule intended to ensure that FS links are operated efficiently. We propose to allow temporary operations below the minimum capacity under certain circumstances, which will enable FS links--particularly long links in rural areas--to maintain critical communications during periods of fading. 11. We propose changes to our rules to allow FS licensees to maintain communications when adverse propagation characteristics would otherwise force communications to be terminated. Specifically, we propose to amend our rules to allow licensees to temporarily drop below minimum payload capacity requirements specified by the rules in certain limited circumstances. These proposed rule changes have the potential to reduce operational costs and increase reliability, which could be particularly important in facilitating the use of wireless backhaul in rural areas. 12. Section 101.141(a)(3) of the Commission's rules establishes minimum payload capacities (in terms of megabits per second) for various channel sizes in certain part 101 bands. The underlying purpose of the rule is to promote efficient frequency use. Although the

Commission has never quantified the time period over which licensees must comply with those standards, the industry has generally construed the payload requirements as applying whenever the link is in service. 13. On May 8, 2009, Alcatel-Lucent, Dragonwave, Inc. Ericsson,

Inc., Exalt Communications, Fixed Wireless Communications Coalition

(FWCC), Harris Stratex Networks and Motorola, Inc. (``Petitioners'') filed a request for interpretation of Sec. 101.141(a)(3) of the

Commission's rules to permit data rates to drop for brief periods below the minimum payload capacity specified in the rules, instead of temporarily having a link go completely out of service, so long as the values mandated by the rules were maintained both in normal operation and on average. 14. On May 14, 2010, FWCC followed up its original request for interpretation with a request for waiver of Sec. 101.141(a)(3) so that it can utilize adaptive modulation to average bit rates over time to combat fading. FWCC acknowledges the Commission's indication in the

National Broadband Plan that it intends to open a rulemaking with regards to adaptive modulation; however, FWCC argues that it urgently needs relief with respect to adaptive modulation and does not want to wait for a rulemaking cycle to be completed. 15. We agree with Verizon that a rulemaking is necessary to implement the policy interpretation sought in the FWCC request and we therefore deny

Page 52188

the FWCC request for declaratory ruling in this instance because the requested interpretation is inconsistent with the plain language of the current rule. The current rule specifies a ``minimum'' payload capacity, which commenters admit has been interpreted to mean that it must be complied with at all times when the system is in operation.

Such an interpretation is consistent with the use of the word

``minimum.'' FWCC's proposed interpretation deviates from the commonly understood meaning of the rule. Furthermore, the fact that licensees had interpreted the rule as establishing a benchmark that must be complied with at all times is further evidence that it would not be appropriate to change the meaning of an established rule under the guise of a declaratory ruling. We also note that the comments raise various policy issues that are best addressed through the rulemaking process. 16. Nonetheless, we believe that it is in the public interest to commence a rulemaking proceeding to amend our rules to facilitate the use of adaptive modulation by allowing licensees to maintain communications in the face of adverse propagation characteristics.

Adaptive modulation has the potential to reduce operational costs and facilitate the use of wireless backhaul in rural areas. While our current rules allow the use of adaptive modulation, they would require all modulation modes to comply with the minimum payload capacities contained in the rules at all times. Allowing carriers to operate below the current efficiency standards for short periods when it is necessary to maintain an operational link, without a need for waiver, could enable carriers to save on costs and enhance reliability of microwave links. Accordingly, we seek comment in the context of this NPRM on revising Sec. 101.141 of the Commission's rules to allow greater use of adaptive modulation by FS licensees. 17. Adaptive modulation can allow communications to be maintained during adverse propagation conditions. Given the critical backhaul and public safety applications of FS stations, we find this benefit to be significant. By allowing this level of flexibility in our efficiency standards we hope to provide carriers with a way to lower their costs yet still use the spectrum efficiently. 18. We are concerned, however, that the proposal to allow compliance with the efficiency standards ``on average'' and ``during normal operation'' is too vague and open-ended. Commenters have noted that it is standard engineering practice to design microwave links to have 99.995 percent or higher link availability. Under those circumstances, we believe the standard proposed in the FWCC request would give licensees too much latitude to deploy inefficient systems that would be inconsistent with good engineering practices. To the extent the underlying concern behind this proposal is that the requirements of the rule are too strict and inhibit full use of the spectrum, we believe the better approach would be to review those standards and amend them, if appropriate. Moreover, using an ``on average'' standard would make enforcement of the minimum payload capacity rule more difficult. We also tentatively conclude that the equipment restrictions proposed by Verizon would not be in the public interest because, as noted by HSX, such restrictions could increase equipment prices for carriers and consumers. 19. We tentatively conclude to adopt a more carefully tailored approach by amending Sec. 101.141 of the Commission's rules to state that the minimum payload capacity requirements must be met at all times, except during anomalous propagation conditions, when lower capacities may be utilized in order to maintain communications. This approach will allow licensees to take advantage of the benefits of adaptive modulation without unduly undercutting the efficiency purpose that led to initial adoption of the minimum efficiency requirement. We seek comment on this proposal, as well as alternatives. We also seek comment on what might constitute anomalous signal fading. In that regard, we also propose to adopt AT&T's suggestion to require licensees that wish to be able to temporarily use modulations below the minimum payload capacity in Sec. 101.141 of the Commission's rules to state that fact in their prior coordination notices. We seek comment on whether, how, and to what extent this information should be logged and made part of the station records under Sec. 101.217 to facilitate enforcement. We also seek comment on related issues, including whether the rules should specify a minimum amount of time a link is operational or a minimum efficiency standard below which an FS station may not fall even when using adaptive modulation. 20. We deny FWCC's waiver request. Given the concerns we have regarding FWCC's proposal to use an ``on average'' standard, FWCC has not shown that it would be in the public interest to allow operation under such circumstances. Furthermore, FWCC's claims that there is an urgent need for relief are conclusory and lack any specificity. We therefore conclude that the better course is to proceed through our normal rulemaking process and determine the best means of allowing licensees to take advantage of adaptive modulation.

Permitting Auxiliary Fixed Stations 21. We seek comment on a proposal to permit substantially spatial reuse of scarce microwave spectrum, which may permit more efficient use of the spectrum thereby potentially reducing the cost of using FS spectrum for backhaul and other important purposes. Specifically, we propose to allow FS licensees to operate ``auxiliary stations'' in conjunction with existing microwave links, subject to conditions designed to enable the use of such stations to augment capacity while safeguarding existing users in the band. We seek comment on permitting

FS licensees to coordinate and deploy multiple links--a primary link and ``auxiliary'' links. 22. The Commission's current rules define a fixed station as ``[a] station operating at a fixed location,'' and require a license for each station. In the part 101 Operational Fixed Services, the rules require evaluation of proposed point-to-point fixed microwave stations on a site-by-site, path-by-path basis, and do not provide exceptions based on the aggregation of multiple sites and paths. Each license application must include ``all technical information required by the application form and any additional information necessary to fully describe the proposed facilities and to demonstrate compliance with all technical requirements of the rules governing the radio service involved * * *.'' This construct is different from services based on geographic area licensing, where a licensee, subject to certain exceptions, is allowed to place transmitters throughout its service area without individual Commission approval once it has obtained its geographic area license, subject to compliance with applicable service rules. 23. On February 23, 2007, Wireless Strategies, Inc. (WSI) filed a petition asking the Commission to issue a declaratory ruling

``confirming that a Fixed Service licensee is permitted to simultaneously coordinate multiple links whose transmitter elements collectively comply with the Commission's antenna standards and frequency coordination procedures.'' Comment on WSI's petition was sought by public notice, and 27 parties filed comments, reply comments and ex parte statements. 24. In its original proposal, WSI proposed that it would be unnecessary to separately coordinate auxiliary elements within the side lobes of the main station because ``the antenna

Page 52189

characteristics provided by the applicant to the coordinator, in addition to describing the main lobe, also incorporate the properties of the multiple distributed elements to be used for communication with other locations.'' WSI referred to that concept as ``concurrent coordination.'' In response to arguments that coordination of the auxiliary elements is necessary, WSI modified its proposal.

Specifically, WSI suggests that, once a ``main link'' is successfully coordinated and licensed, an auxiliary element would only be added (1) following regular frequency coordination and filing of an application for major modification of the license of the associated location whose frequency it would reuse, and (2) on a secondary basis to any future coordinated paths. 25. Initially, we determine that the WSI proposal is not consistent with our rules as currently drafted, and we therefore deny the request for declaratory ruling. WSI's proposal to consider the performance of a system on an aggregate basis is not consistent with the plain wording of our rules for two reasons. First, the rules require evaluation of proposed point-to-point fixed microwave stations on a site-by-site, path-by-path basis, and do not provide exceptions based on the aggregation of multiple sites and paths. Second, WSI's proposal is inconsistent with the antenna standards rule, Sec. 101.115 of the

Commission's rules, because it proposes the use of antennas that do not meet those standards. 26. While we find that the concept proffered by WSI is not consistent with the current rules, we do find it worthy of further consideration. Because we cannot authorize this operation as a declaratory ruling, we seek comment in this NPRM on whether we should make necessary changes to our part 101 rules to afford licensees the opportunity to operate in this manner. We find that it is in the public interest to initiate a rulemaking proceeding on our own motion to consider changes to our part 101 rules to allow operation in the manner contemplated by WSI. A rulemaking proceeding will allow us to gather information on the proposed types of operations, discuss specific rule changes, and consider further the arguments for and against the operations that WSI contemplates. 27. We seek comment on the potential benefits of permitting auxiliary stations under our part 101 rules--the uses they may support, the efficiencies that may be achieved--as well as on the potential harms. Reserving judgment on the ultimate balancing of those benefits and harms, we observe that a series of changes to our part 101 rules would be necessary in order to effectuate a part 101 regime including auxiliary stations. Specifically, we seek comment on the following elements of such a regime:

Each auxiliary station must operate on the same frequencies as the main licensed link.

Auxiliary stations must not cause any incremental interference to other primary links, i.e., they must not cause any more interference to them than the main link would cause. This result can, possibly, be achieved by alternating transmissions between the primary station and the auxiliary stations on a time-division multiplexed basis or by any other method that achieves the required result.

Auxiliary stations will be secondary in status and have no right to claim protection from interference from any primary stations, including stations in other services, such as BAS, CARS, and satellite stations, other than interference that violates the protection rights of the main link. Otherwise, auxiliary stations will have a right to claim protection only from later-deployed auxiliary stations.

Auxiliary stations would have to be coordinated in advance with other licensees and applicants pursuant to the frequency coordination process specified in Sec. 101.103 of the Commission's rules.

After coordination, the licensee of the main link would file applications to make major modifications to the main link license to add auxiliary stations. In those bands where conditional authority is available, applicants could operate their auxiliary stations as soon as they complete the frequency coordination process and file their application with the Commission, subject to the usual conditions and exceptions to conditional authority. Alternatively, we seek comment on whether, consistent with the procedures set out in Sec. 101.31 of our rules for temporary fixed links, we could allow main link licensees to file blanket applications to operate temporary auxiliary stations at multiple locations within specified geographic areas surrounding the associated main links.

Until we gain further experience with system operation under these new rules, we further propose to require that auxiliary stations be restricted from communicating directly with each other, i.e., that they be allowed to communicate directly only with the primary link's transmitter or receiver. We propose this restriction because it would reduce the chance of interference.

Auxiliary stations would not be subject to the antenna standards or minimum path length requirements that apply to main links.

Eliminating the beamwidth requirement will enable licensees to use smaller, less expensive antennas that put less of a load on support structures and thereby reduce the cost of those structures. The main link, however, would still have to comply with those requirements.

Main links would remain subject to existing loading and path length requirements, but auxiliary stations would be exempt from the loading and path length requirements. Alternatively, in determining compliance with the loading requirements, licensees would be allowed to aggregate loading on the main link and auxiliary stations. We seek comment on both alternatives. Parties supporting the second alternative should explain how to avoid double counting traffic between a main link and an auxiliary link that also traverses the main link.

Like primary stations, auxiliary stations would be required to obtain the necessary approvals for FAA tower clearance and to comply with environmental requirements covering non-ionizing radiation hazards, zoning, the National Environmental Act of 1969 and the National Historical Act of 1966, as applicable. 28. We believe these proposed rule changes could facilitate the provision of advanced backhaul services in the FS bands while providing protection to existing users in the band. We seek comment on these proposals, as well as alternatives. 29. We note that FS and satellite users raised concerns about the proposal in the record on the WSI Petition, arguing that it is inconsistent with the frequency coordination and antenna standards rules. Our main concerns are avoiding interference to existing operations in the bands, maintaining the reliability and integrity of existing systems, and avoiding a situation where spectrum becomes unavailable to FS applicants and other users that share spectrum with

FS. In order to compare the relative benefits of and risks of allowing auxiliary stations, we request additional information from commenters. 30. Initially, we seek more specific information on the types of operations auxiliary stations could be used for. Information that would be useful would include: (1) An estimate of how many systems parties contemplate operating with auxiliary stations, (2) information on whether such systems would typically be deployed in urban or rural areas, (3) the types of uses to which such systems would be put, (4) the contemplated distances between the auxiliary stations and the main link, and

Page 52190

(5) the relative amount of traffic anticipated to be carried on the main link versus the auxiliary links. 31. We also seek comment on why the contemplated operations could not be accommodated in existing part 101 services and bands that allow point-to-multipoint operation, such as the Local Multipoint

Distribution Service, the 24 GHz Service, and the operations in the 38.6-40.0 GHz band. Those bands feature geographic area licensing that would appear to be well suited for the type of operations involving multiple stations, whether ``auxiliary'' or primary. 32. We note that the examples WSI provides propose use of the Lower 6 GHz Band (5925 MHz-6425 MHz). While the Commission authorized 30 megahertz bandwidth links in the Upper 6GHz Band in the 6/23 GHz Report and Order, we anticipate that there will be considerable demand for those frequencies. We seek comment on whether there is sufficient capacity in those bands to accommodate many operations of the type contemplated by WSI, in addition to the existing uses in the band. We are particularly interested in the experiences of parties who have coordinated links in that band. 33. We seek comment on whether our proposal would strike the appropriate balance between auxiliary stations and other operations, particularly primary microwave links. We propose requiring frequency coordination and adding auxiliary sites to the license through our normal application process and seek comment on whether those requirements would be sufficient protection. Furthermore, given that auxiliary stations would be secondary to main links and could not be used to prevent coordination of main links, it appears unlikely that they could be used to establish pseudo-geographic service areas. We seek comment on concerns raised by some commenters that auxiliary links could give applicants an incentive to propose main links that would allegedly specify excessive power, and would allegedly be designed to maximize interference and the preclusive effect on other nearby operations. We seek comment on the applicability of Sec. 101.103(d)(1) of the Commission's rules, which requires applicants to avoid interference in excess of permissible levels to other users and requires applicants to make ``every reasonable effort'' to avoid blocking the growth of prior coordinated systems, to main links associated with auxiliary stations. 34. Finally, we seek comment on whether we should establish restrictions on the locations of auxiliary stations. One option would be to confine auxiliary stations to an area within a defined field strength level of the main link. Another option would be to provide that an auxiliary station could not generate field strength that exceeds the primary station's field strength beyond the perimeter where the primary station generates the field strength discussed above. We emphasize that compliance with such restrictions would not absolve auxiliary stations from the further requirement that they not cause incremental interference to other primary links. We invite comment on the appropriate metrics to use for defining the relevant field strength perimeters, as well as alternative means of establishing limitations on the locations of auxiliary stations.

Notice of Inquiry 35. This Notice of Inquiry is intended to generate a record about other potential changes to part 101 rules that could potentially reduce wireless backhaul costs and increase investment in broadband deployment. In the first part, we ask about the possibility of relaxing efficiency standards in rural areas, where links may be longer and the density of deployment lower than in urban areas. In the second part, we inquire as to whether changes in the part 101 rules to permit smaller antennas could similarly reduce costs and stimulate investment. We invite commenters to offer specific proposals for rule changes on these issues, and encourage a full discussion of the advantages and disadvantages of rule changes.

Modification of Efficiency Standards in Rural Areas 36. We seek comment on whether lowering the current efficiency standards in rural areas would lower costs associated with providing backhaul service. Under our current rules, rural providers must maintain the same capacity requirements also maintained by carriers in more densely populated metropolitan areas. Lower traffic volume on the rural networks and greater distances between microwave links may make maintenance of these minimum capacity requirements financially prohibitive in some instances. To the extent wireless carriers cannot obtain rural backhaul facilities at reasonable rates, lowering the current efficiency standards in rural areas could reduce the costs associated with wireless backhaul. We therefore seek additional comment on whether relaxing the current efficiency standards in rural areas would benefit rural licensees without diminishing the availability of already increasingly scarce backhaul spectrum. 37. Section 101.141(a)(3) of the Commission's rules establishes minimum payload capacities (in terms of megabits per second) and minimum traffic loading payload (as a percentage of payload capacity) for various channel sizes in certain part 101 bands. The underlying purpose of the rule is to promote efficient frequency use. The requirements set forth in the rule apply equally to stations in urban areas and to stations in rural areas. The Wireless Telecommunications

Bureau has historically granted waivers to licensees in rural and remote areas where operation of microwave facilities at the required efficiency standards would cause financial hardship to the extent that the underlying purpose of the rule would be frustrated. We ask whether this waiver policy should be reflected in our rules so that applicants could obtain facilities for backhaul in rural areas without the cost and delay inherent in seeking a waiver of our rules. 38. To the extent commenters support lowering the efficiency standards in rural areas, we seek specific proposals to modify the efficiency standards in Sec. 101.141(a)(3) of the Commission's rules.

Proponents of changes to the standards should explain how changes would provide more flexibility and facilitate deployment of backhaul and other facilities in rural areas. Commenters should also address the impact such changes would have on existing licensees, including licensees in other services that share spectrum with FS. We ask whether any changes would be consistent with the underlying purpose of Sec. 101.141(a)(3), which is to promote efficient utilization of the spectrum. 39. In connection with this inquiry, we seek comment on the definition of ``rural'' that might be used to determine which geographic areas would be defined as rural under a revised rule relaxing efficiency standards in rural areas. In the Commission's 2004

Report and Order addressing the ways to facilitate and enhance the provision of spectrum-based service in rural areas the Commission provided a baseline definition of ``rural areas'' as, ``those counties

(or equivalent) with a population density of 100 persons per square mile or less, based upon the most recently available Census data.'' The

Commission first used this definition as a proxy definition in its annual CMRS Competition Report for purposes of analyzing the average number of mobile telephony competitors in rural versus non-rural counties. At the time that the Commission adopted this definition, it

Page 52191

was determined that such a specific definition was necessary to establish continuity so that the Commission would have a basis for comparison of the effects of its ``rural area'' policies over time. It was determined in that same proceeding that the definition would be treated as a presumption to be applied for current and future

Commission wireless radio service rules, policies and analyses for which the term ``rural area'' has not been expressly defined. In light of this established presumption, we seek comment on whether this definition is suitable to determine areas which should be considered rural for purposes of microwave efficiency standards in this band. We also seek comment on potential alternative definitions and any supporting reasons for why a specific definition should be utilized.

Review of Part 101 Antenna Standards 40. We seek comment on whether to review the antenna standards in any particular band to allow smaller antennas, to identify opportunities to facilitate increased deployment of FS facilities without subjecting other licensees to increased interference. The

National Broadband Plan noted that it was important to ensure that the

Commission's antenna standards are up to date ``in order to maximize the cost-effectiveness of microwave services.'' Smaller antennas may be cheaper, easier to install, and generate fewer objections than antennas specified by the current requirements. We ask whether smaller antennas can be accommodated in any FS band without causing interference to other users in the band. 41. Section 101.115(b) of the Commission's rules establishes directional antenna standards designed to maximize the use of microwave spectrum while avoiding interference between operators. More specifically, the Commission's rules set forth certain requirements, specifications, and conditions pursuant to which FS stations may use antennas that comply with either the more stringent performance standard in Category A (also known as Standard A) or the less stringent performance standard in Category B (also known as Standard B). In general, the Commission's rules require a Category B user to upgrade if the antenna causes interference problems that would be resolved by the use of a Category A antenna. The rule on its face does not mandate a specific size of antenna. Rather, it specifies certain technical parameters--maximum beamwidth, minimum antenna gain, and minimum radiation suppression--that, depending on the state of technology at any point in time, directly affect the size of a compliant antenna. The

Commission adopts antenna specifications based on the technical sophistication of the communications equipment and the needs of the various users of the band at the time. Indeed, the Commission adopted similar technical specifications that effectively limited the size of antennas used in other bands, including those used by certain types of satellites. Periodically, the Commission has since reconsidered some of those antenna specifications in light of the technological evolution of communications equipment. 42. Smaller antennas can have several advantages for carriers and consumers. In the 11 GHz Report and Order, the Commission noted that smaller antennas:

Cost less to manufacture and distribute, are less expensive to install because they weigh less and need less structural support, and cost less to maintain because they are less subject to wind load and other destructive forces. In addition, proponents of the rule change contend that the modest weight of small antennas makes them practical for installation at sites incapable of supporting large dishes, including many rooftops, electrical transmission towers, water towers, monopoles and other radio towers. Proponents also state that 0.61 meter antennas raise fewer aesthetic objections, thereby permitting easier compliance with local zoning and homeowner association rules and generating fewer objections. 43. On the other hand, smaller antennas have increased potential to cause interference because smaller antennas ``result in more radiofrequency energy being transmitted in directions away from the actual point-to-point link.'' 44. In light of the sharp increase in demand for FS facilities for backhaul and other purposes, we believe it is appropriate to inquire whether we should review our antenna standards in any particular band.

Our goal in this inquiry would be to identify opportunities to facilitate increased deployment of FS facilities without subjecting other licensees to increased interference. Parties that believe that a review of antenna standards is appropriate should: (1) Identify specific FS bands where they believe the antenna standards should be reviewed, (2) offer specific proposals for new standards, (3) describe the technological or other changes that they believe support new antenna standards, (4) describe how the new antenna standards would facilitate deployment in that band, (5) discuss the impact such new antenna standards would have on other licensees in the band, including both FS licensees and other services that share the band, (6) discuss whether the proposed standards should apply to only rural areas or all geographical areas. Other parties are encouraged to provide their evaluation of proposed changes.

Increasing Flexibility Generally 45. We also seek comment on whether we should examine any additional modifications to the part 101 rules, or other policies or regulations, to promote flexible, efficient and cost-effective provisions of wireless backhaul service. For example, are there any additional measures that could be taken to promote additional sharing with satellite, broadcast and other services? We also seek comment on any additional safeguards that may be needed to adequately protect the interests of existing licensees. Additionally, we seek comment on whether there are any changes we could make to our frequency coordination or application processes that could make it easier for applicants to access backhaul spectrum. We also ask commenters to identify any of our current rules or processes that could act as an unintended barrier to obtaining backhaul spectrum.

Initial Regulatory Flexibility Analysis 49. As required by the Regulatory Flexibility Act of 1980, as amended (RFA), the Commission has prepared this present Initial

Regulatory Flexibility Analysis (IRFA) of the possible significant economic impact on a substantial number of small entities by the policies and rules proposed in this Notice of Proposed Rulemaking

(NPRM). Written public comments are requested on this IRFA. Comments must be identified as responses to the IRFA and must be filed by the deadlines specified in the NPRM for comments. The Commission will send a copy of this NPRM, including this IRFA, to the Chief Counsel for

Advocacy of the Small Business Administration (SBA). In addition, the

NPRM and IRFA (or summaries thereof) will be published in the Federal

Register.

1. Need for, and Objectives of, the Proposed Rules 50. In this NPRM, we propose four changes to our rules involving microwave stations. First, we propose allowing fixed service stations to operate in the 6875-7125 MHz and 12700-13200 MHz bands. Second, we propose to eliminate the prohibition on broadcasters using part 101 stations as the final radiofrequency (RF) link in the chain of distribution of the program material to broadcast stations. Third, we propose to amend our minimum payload capacity rule to facilitate the use of adaptive modulation to allow licensees to maintain communications by briefly reducing the rate at which they send data.

   Fourth, we propose to allow part 101 licensees to add auxiliary stations in order to allow substantially greater reuse of microwave spectrum and substantially reduce the cost of using FS spectrum for backhaul and other important purposes. 51. With respect to the first proposal, we anticipate that demand for fixed service spectrum will increase substantially as it is increasingly used for wireless backhaul and other important purposes.

   The 6875-7125 MHz and 12700-13200 MHz bands are currently assigned to television pickup, television studio-transmitter links, television relay stations, television translator relay stations, and mobile only

   CARS. Based upon our experience in other bands, we believe assigning this band to the fixed service would be compatible with these other services using the frequency coordination procedures in Sec. 101.103 of the Commission's rules. Assigning this spectrum to the fixed service would help provide additional spectrum that could be used for wireless backhaul and other critical applications. 52. Second, Sec. 101.603(a)(7) of the Commission's rules, commonly known as the ``final link'' rule, prohibits broadcasters from using part 101 stations as the final radiofrequency (RF) link in the chain of distribution of the program material to broadcast stations. The rule ensures that private operational fixed stations are used for private, internal purposes and prevents broadcasters from causing congestion when part 74 Broadcast Auxiliary Service (BAS) frequencies are available. In light of recent technological and regulatory developments, we believe the ``final link'' rule may no longer serve its intended purpose and may in fact inhibit the full use of part 101 spectrum. As broadcasters and other microwave users move to digital- based systems, we question whether it makes sense to maintain regulatory restrictions based on the type of content that the digital data represents. Based on the record developed in waiver requests granted by the Wireless Telecommunications Bureau, it appears that there are an increasing number of markets where Broadcast Auxiliary

   Service (BAS) spectrum is scarce. Furthermore, the rule may impose additional costs by requiring broadcasters to build two different systems: One system to carry program material to the transmitter site, and a separate system to handle other data. In light of the extensive sharing between BAS and FS of the same bands, we believe it is appropriate to provide broadcasters with additional flexibility to use the FS bands. We therefore propose to eliminate this rule.

   Page 52193

   53. Our third proposal is to amend out part 101 technical rules to facilitate the use of adaptive modulation. Section 101.141(a)(3) of the

   Commission's rules establishes minimum payload capacities (in terms of megabits per second) for various channel sizes in certain part 101 bands. The underlying purpose of the rule is to promote efficient frequency use. Although the Commission has never quantified the time period over which licensees must comply with those standards, the industry has generally construed the payload requirements as applying whenever the link is in service. Fixed service links, especially long links, are subject to atmospheric fading: A temporary drop in received power caused by changes in propagation conditions. Fading leads to an increase in bit errors, and sometimes to a complete loss of communications. One way to combat fading is by briefly reducing the data rate, which requires a temporary change in the type of modulation, a process called ``adaptive modulation.'' The use of adaptive modulation may reduce the minimum payload capacity below the value specified in the rule for a short time, although this still represents an increase over the otherwise zero level during the fade. Adaptive modulation has public interest benefits of allowing communications to be maintained during adverse propagation conditions. Given the critical backhaul and public safety applications of fixed service stations, we find this benefit to be significant. By allowing this level of flexibility in our efficiency standards we hope to provide carriers with a way to lower their costs yet still use the spectrum efficiently.

   We therefore propose to amend our rules to state that the minimum payload capacity requirements must be complied with at all times, except during anomalous propagation conditions, when lower capacities may be utilized in order to maintain communications. That approach would allow licensees to take advantage of the benefits of adaptive modulation while ensuring efficient use of the spectrum. 54. Finally, we seek comment on allowing substantially greater reuse of microwave spectrum and substantially reduce the cost of using fixed spectrum for backhaul and other important purposes by allowing licensees to place auxiliary antennas that the licensee of each primary

   FS link be allowed to deploy as many auxiliary stations as it wishes under the following conditions:

   Each auxiliary station must operate on the same frequencies as the main licensed link.

   Auxiliary stations must not cause any incremental interference to other primary links, i.e., they must not cause any more interference to them than the main link would cause. This result can, possibly, be achieved by alternating transmissions between the primary station and the auxiliary stations on a time-division multiplexed basis or by any other method that achieves the required result.

   Auxiliary stations will be secondary in status and have no right to claim protection from interference from any primary stations, including stations in other services, such as BAS, CARS, and satellite stations, other than interference that violates the protection rights of the main link. Otherwise, auxiliary stations will have a right to claim protection only from later-deployed auxiliary stations.

   Auxiliary stations would have to be coordinated in advance with other licensees and applicants pursuant to the frequency coordination process specified in Sec. 101.103 of the Commission's rules.

   After coordination, the licensee of the main link would file applications to make major modifications to the main link license to add auxiliary stations. In those bands where conditional authority is available, applicants could operate their auxiliary stations as soon as they complete the frequency coordination process and file their application with the Commission, subject to the usual conditions and exceptions to conditional authority. Alternatively, we seek comment on whether, consistent with the procedures set out in Sec. 101.31 of our rules for temporary fixed links, we could allow main link licensees to file blanket applications to operate temporary auxiliary stations at multiple locations within specified geographic areas surrounding the associated main links.

   Until we gain further experience with system operation under these new rules, we further propose to require that auxiliary stations be restricted from communicating directly with each other, i.e., that they be allowed to communicate directly only with the primary link's transmitter or receiver. We propose this restriction because it would reduce the chance of interference.

   Auxiliary stations would not be subject to the antenna standards or minimum path length requirements that apply to main links.

   Eliminating the beamwidth requirement will enable licensees to use smaller, less expensive antennas that put less of a load on support structures and thereby reduce the cost of those structures. The main link, however, would still have to comply with those requirements.

   Main links would remain subject to existing loading and path length requirements, but auxiliary stations would be exempt from the loading and path length requirements. Alternatively, in determining compliance with the loading requirements, licensees would be allowed to aggregate loading on the main link and auxiliary stations. We seek comment on both alternatives. Parties supporting the second alternative should explain how to avoid double counting traffic between a main link and an auxiliary link that also traverses the main link.

   Like primary stations, auxiliary stations would be required to obtain the necessary approvals for FAA tower clearance and to comply with environmental requirements covering non-ionizing radiation hazards, zoning, the National Environmental Act of 1969 and the National Historical Act of 1966, as applicable.

2. Legal Basis 55. The proposed action is authorized pursuant to sections 1, 2, 4(i), 7, 10, 201, 214, 301, 302, 303, 307, 308, 309, 310, 319, 324, 332 and 333 of the Communications Act of 1934, as amended, 47 U.S.C. 151, 152, 154(i), 157, 160, 201, 214, 301, 302, 303, 307, 308, 309, 310, 319, 324, 332, and 333.

3. Description and Estimate of the Number of Small Entities to Which the Proposed Rules Will Apply 56. The RFA directs agencies to provide a description of, and, where feasible, an estimate of the number of small entities that may be affected by the proposed rules and policies, if adopted. The RFA generally defines the term ``small entity'' as having the same meaning as the terms ``small business,'' ``small organization,'' and ``small governmental jurisdiction.'' In addition, the term ``small business'' has the same meaning as the term ``small business concern'' under the

   Small Business Act. A ``small business concern'' is one which: (1) Is independently owned and operated; (2) is not dominant in its field of operation; and (3) satisfies any additional criteria established by the

   SBA. 57. Our proposed action, if implemented, may, over time, affect small entities that are not easily categorized at present. We therefore describe here, at the outset, three comprehensive, statutory small entity size standards. First, nationwide, there are a total of approximately 27.2 million small businesses, according to the SBA. In addition, a ``small organization'' is

   Page 52194

   generally ``any not-for-profit enterprise which is independently owned and operated and is not dominant in its field.'' Nationwide, as of 2002, there were approximately 1.6 million small organizations.

   Finally, the term ``small governmental jurisdiction'' is defined generally as ``governments of cities, towns, townships, villages, school districts, or special districts, with a population of less than fifty thousand.'' Census Bureau data for 2002 indicate that there were 87,525 local governmental jurisdictions in the United States. We estimate that, of this total, 84,377 entities were ``small governmental jurisdictions.'' Thus, we estimate that most governmental jurisdictions are small. 58. Wireless Telecommunications Carriers (except satellite).

   Microwave services include common carrier, private-operational fixed, and broadcast auxiliary radio services. At present, there are approximately 31,428 common carrier fixed licensees and 79,732 private and public safety operational-fixed licensees and broadcast auxiliary radio licensees in the microwave services. The Commission has not yet defined a small business with respect to microwave services. For purposes of the IRFA, we will use the SBA definition that applies to

   Wireless Telecommunications Carriers (except satellite)--i.e., an entity with no more than 1,500 persons. Since 2007, the Census Bureau has placed wireless firms within this new, broad, economic census category. Prior to that time, such firms were within the now-superseded categories of ``Paging'' and ``Cellular and Other Wireless

   Telecommunications.'' Under the present and prior category definitions, the SBA has deemed a wireless business to be small if it has 1,500 or fewer employees. For the category of Wireless Telecommunications

   Carriers (except Satellite), preliminary data for 2007, i.e., data based on the superseded SBA classification, show that there were 11,927 firms operating that year. While the Census Bureau has not released data on such establishments broken down by number of employees, we note that the Census Bureau lists total employment for all firms in that sector at 281,262. Since all firms with fewer than 1,500 employees are considered small, given the total employment in the sector, we estimate that the vast majority of wireless firms are small. We estimate that virtually all of the Fixed Microwave licensees (excluding broadcast auxiliary licensees) would qualify as small entities under the SBA definition. 59. Radio Broadcasting. A radio broadcasting station is an establishment primarily engaged in broadcasting aural programs by radio to the public. Included in this industry are commercial, religious, educational, and other radio stations. Radio broadcasting stations which primarily are engaged in radio broadcasting and which produce radio program materials are similarly included. However, radio stations that are separate establishments and are primarily engaged in producing radio program material are classified under another NAICS number. The

   SBA has established a small business size standard for this category, which is: Firms having $7 million or less in annual receipts. According to BIA Advisory Services, LLC, MEDIA Access Pro Database on March 17, 2009, 10,884 (95%) of 11,404 commercial radio stations have revenue of

   $6 million or less. Therefore, the majority of such entities are small entities. We note, however, that many radio stations are affiliated with much larger corporations having much higher revenue. Our estimate, therefore, likely overstates the number of small entities that might be affected by any ultimate changes to the rules and forms. 60. Television Broadcasting. The SBA defines a television broadcasting station as a small business if such station has no more than $14.0 million in annual receipts. Business concerns included in this industry are those ``primarily engaged in broadcasting images together with sound.'' The Commission has estimated the number of licensed commercial television stations to be 1,392. According to

   Commission staff review of the BIA/Kelsey, MAPro Television Database

   (``BIA'') as of April 7, 2010, about 1,015 of an estimated 1,380 commercial television stations (or about 74 percent) have revenues of

   $14 million or less and, thus, qualify as small entities under the SBA definition. The Commission has estimated the number of licensed noncommercial educational (NCE) television stations to be 390. We note, however, that, in assessing whether a business concern qualifies as small under the above definition, business (control) affiliations must be included. Our estimate, therefore, likely overstates the number of small entities that might be affected by our action, because the revenue figure on which it is based does not include or aggregate revenues from affiliated companies. The Commission does not compile and otherwise does not have access to information on the revenue of NCE stations that would permit it to determine how many such stations would qualify as small entities. 61. In addition, an element of the definition of ``small business'' is that the entity not be dominant in its field of operation. We are unable at this time to define or quantify the criteria that would establish whether a specific television station is dominant in its field of operation. Accordingly, the estimate of small businesses to which rules may apply do not exclude any television station from the definition of a small business on this basis and are therefore over- inclusive to that extent. Also, as noted, an additional element of the definition of ``small business'' is that the entity must be independently owned and operated. We note that it is difficult at times to assess these criteria in the context of media entities and our estimates of small businesses to which they apply may be over-inclusive to this extent.

4. Description of Projected Reporting, Recordkeeping, and Other

   Compliance Requirements 62. This Notice of Proposed Rulemaking imposes no new reporting or recordkeeping requirements.

5. Steps Taken To Minimize Significant Economic Impact on Small

   Entities, and Significant Alternatives Considered 63. As noted above, this NPRM proposes rules to (1) allow fixed service stations to operate in the 6875-7125 MHz band, (2) eliminate the prohibition on broadcasters using part 101 stations as the final radiofrequency (RF) link in the chain of distribution of the program material to broadcast stations, (3) amend our minimum payload capacity rule to facilitate the use of adaptive modulation to allow licensees to maintain communications by briefly reducing the rate at which they send data, and (4) allow part 101 licensees to add auxiliary stations. These actions would provide additional options to all licensees, including small entity licensees. Such action will serve the public interest by making additional spectrum available for fixed service users, providing additional flexibility for broadcasters to use microwave spectrum, allowing communications to be maintained during adverse propagation conditions, facilitating the efficient use of the 6 GHz and 23 GHz bands. The rules could therefore open up economic opportunities to a variety of spectrum users, including small businesses. 64. Generally, the alternative approach would be to maintain the existing rules. If the rules were not changed, the 6875-7125 MHz and 12700-13200 MHz bands would remain unavailable for fixed service use.

   Given the increasing demand for part 101 spectrum for backhaul and other uses, not making that spectrum available may

   Page 52195

   make it increasingly difficult to meet demand for microwave facilities.

   If the prohibition on broadcasters using part 101 stations as the final radiofrequency (RF) link in the chain of distribution of the program material to broadcast stations is not eliminated, broadcasters will be limited to using Broadcast Auxiliary Service spectrum for that purpose, and may have to build two separate microwave systems using different frequencies, such an alternative would be inadequate to meet the demands of licensees and therefore less than ideal. If no BAS spectrum is available, broadcasters will have to pay to prepare a request for waiver to access part 101 spectrum and await action on that waiver request before they can begin operation. Such expense and delay may be particularly harmful to small businesses. 65. With respect to our proposal to amend our minimum capacity payload rule to facilitate adaptive modulation, if our rules are not amended to facilitate the use of adaptive modulation, licensees will be unable to fully use technology to maintain critical communications during signal fades. Under the proposal made in the NPRM, the minimum payload capacity requirements must be met at all times, except during anomalous propagation conditions, when lower capacities may be utilized in order to maintain communications. 66. An alternative to the adaptive modulation proposal made in the

   NPRM would be to allow compliance with the efficiency standards ``on average'' and ``during normal operation.'' We believe that standard would give licensees too much latitude to deploy inefficient systems that would be inconsistent with good engineering practices. 67. Finally, while herein we propose to authorize the use of auxiliary stations, we are open to alternatives such as authorizing auxiliary stations in a more limited fashion or not at all, however, if we do not authorize auxiliary stations in some fashion, we may prevent licensees from fully utilizing their spectrum for backhaul and other purposes.

6. Federal Rules That May Duplicate, Overlap, or Conflict With the

   Proposed Rules 68. None.

   Ordering Clauses 69. Accordingly, it is ordered, pursuant to sections 1, 2, 4(i), 7, 10, 201, 214, 301, 302, 303, 307, 308, 309, 310, 319, 324, 332 and 333 of the Communications Act of 1934, 47 U.S.C. 151, 152, 154(i), 157, 160, 201, 214, 301, 302, 303, 307, 308, 309, 310, 319, 324, 332, 333, that this Notice of Proposed Rulemaking and Notice of Inquiry is hereby adopted. 70.

   Page 52202

   subpart I of this chapter may add auxiliary stations to their authorizations in accordance with this section.

   (b) Each auxiliary station must operate on the same frequencies as the main licensed link. Auxiliary stations may communicate directly only with the primary link's receiver.

   (c) Auxiliary stations may not cause any increase in interference to other licensed services, i.e., less than the interference that would be predicted to exist from its own main link. A licensee or prior applicant with auxiliary stations may object to a prior coordination notice based on interference only if such interference would be predicted to exist to the other service based solely on the operation of the main link.

   (d) Auxiliary stations shall not be required to comply with the provisions of Sec. Sec. 101.115, 101.141 and 101.143.

   (e) Licensees seeking to add auxiliary stations shall prior coordinate such stations pursuant to the frequency coordination procedures of Sec. 101.103.

   (f) For each auxiliary station, an application shall be filed on

   Form 601 to modify the license to add the auxiliary station. Such application shall contain the information required in Sec. 101.21.

   Auxiliary stations shall be eligible for conditional authorization pursuant to Sec. 101.31(b) if they comply with the requirements of that section. 8. Amend Sec. 101.101 by adding the entry ``6875-7125'' to the table to read as follows:

   (p) 12,000-12,700 MHz. (1) The Commission has allocated the 12.2- 12.7 GHz band for use by the Direct Broadcast Satellite Service (DBS), the Multichannel Video Distribution and Data Service (MVDDS), and the

   Non-Geostationary Satellite Orbit Fixed Satellite Service (NGSO FSS).

   MVDDS shall be licensed on a non-harmful interference co-primary basis to existing DBS operations and on a co-primary basis with NGSO FSS stations in this band. MVDDS use can be on a common carrier and/or non- common carrier basis and can use channels of any desired bandwidth up to the maximum of 500 MHz provided the EIRP does not exceed 14 dBm per 24 megahertz. Private operational fixed point-to-point microwave stations authorized after September 9, 1983, are licensed on a non- harmful interference basis to DBS and are required to make any and all adjustments necessary to prevent harmful interference to operating domestic DBS receivers. Incumbent public safety licensees shall be afforded protection from MVDDS and NGSO FSS licensees, however all other private operational fixed licensees shall be secondary to DBS,

   MVDDS and NGSO FSS licensees. As of May 23, 2002, the Commission no longer accepts applications for new licenses for point-to-point private operational fixed stations in this band, however, incumbent licensees and previously filed applicants may file applications for minor modifications and amendments (as defined in Sec. 1.929 of this chapter) thereto, renewals, transfer of control, or assignment of license. Notwithstanding any other provisions, no private operational fixed point-to-point microwave stations are permitted to cause harmful interference to broadcasting-satellite stations of other countries operating in accordance with the Region 2 plan for the Broadcasting-

   Satellite Service established at the 1983 WARC.

   (2) Special provisions for incumbent low power, limited coverage systems in the band segments 12.2-12.7 GHz. (i) As of May 23, 2002, the

   Commission no longer accepts applications for new stations in this service and incumbent stations may remain in service provided they do not cause harmful interference to any other primary services licensed in this band as described in paragraph (p) of this section. However, incumbent licensees and previously filed applicants may file applications for minor modifications and amendments (as defined in

   Sec. 1.929 of this chapter) thereto, renewals, transfer of control, or assignment of license.

   (ii) Prior to December 8, 2000, notwithstanding any contrary provisions in this part, the frequency pairs 12.220/12.460 GHz, 12.260/ 12.500 GHz, 12.300/12.540 GHz and 12.340/12.580 GHz, were authorized for low power, limited coverage systems subject to the following provisions:

   (A) Maximum equivalent isotropically radiated power (EIRP) shall be 55 dBm;

   (B) The rated transmitter output power shall not exceed 0.5 watts;

   (C) Frequency tolerance shall be maintained to within 0.01 percent of the assigned frequency;

   (D) Maximum beamwidth shall not exceed 4[deg]. However, the sidelobe suppression criteria contained in Sec. 101.115 shall not apply, except that a minimum front-to-back ratio of 38 dB shall apply;

   (E) Upon showing of need, a maximum bandwidth of 12 MHz may be authorized per frequency assigned;

   (F) Radio systems authorized under the provisions of this section shall have no more than three hops in tandem, except upon showing of need, but in any event the maximum tandem length shall not exceed 40 km

   (25 miles);

   (G) Interfering signals at the receiver antenna terminals of stations authorized under this section shall not exceed -90 dBm and -70 dBm respectively, for co-channel and adjacent channel interfering signals, and

   (H) Stations authorized under the provisions of this section shall provide the protection from interference specified in Sec. 101.105 to stations operating in accordance with the provisions of this part.

   (q) 12700 to 13200 MHz. 30 MHz maximum authorized bandwidth.
