Equipment Authorization for Portable Earth-Station Transceivers and Out-of-Band Emission Limits for Mobile Earth Stations

AGENCY: Federal Communications Commission.

ACTION: Final rule.

SUMMARY: The Commission has amended its rules to establish a prior authorization requirement for importation, sale, lease, offering for sale or lease, or shipment or distribution for sale or lease of portable earth-station transceivers. The Commission has also revised rule provisions pertaining to responsibility for operation of earth- station transceivers and limits on out-of-band emissions from mobile earth-station transceivers.

DATES: Effective March 8, 2004, except for Sec. 25.129 and the changes in Sec. Sec. 1.1307, 2.1033, 2.1204, and 25.132, which contain information collection requirements that have not been approved by the Office of Management and Budget. The FCC will publish a document in the Federal Register announcing the effective date for those rule changes. Written comments by the public on the information collection requirements must be submitted on or before April 6, 2004. Written comments must be submitted by the Office of Management and Budget (OMB) on the proposed and/or modified information collection requirements on or before April 6, 2004.

Compliance Date: When it becomes effective, Sec. 25.129 will require prior authorization to be obtained pursuant to application procedures specified in existing rule provisions in 47 CFR Part 2 for devices imported, sold, leased, or offered, shipped, or distributed for sale or lease after November 19, 2004.

SUPPLEMENTARY INFORMATION: This is a summary of the Second Report and Order in IB Docket No. 99-67, adopted on November 6, 2003, and released on November 18, 2003. The full text of the Second Report and Order is available for public inspection and copying during regular business hours at the FCC Reference Information Center, Portals II, 445 12th Street, SW., Room CY-A257, Washington, DC 20554. The document may also be purchased from the Commission's duplicating contractor, Qualex International, Portals II, 445 12th Street, SW., Room CY-B402, Washington, DC 20554, telephone 202-863-2893, facsimile 202-863-2898, or via e-mail qualexint@aol.com.

In the Second Report and Order the Commission adopted a rule that will require interested parties to obtain equipment authorization for portable earth-station transceivers pursuant to the previously- established certification procedure specified in part 2 of the Commission's rules. The certification procedure requires submission of an application and exhibits to the Commission, including test data showing that a representative sample unit meets the Commission's applicable technical requirements. Devices subject to this requirement may not be imported, sold or leased, offered for sale or lease, or shipped or distributed for sale or lease in the United States after November 19, 2004 unless a pertinent certification application has been granted and the devices are permanently marked with an FCC identification number. The prohibition against importation is modified, however, by an exception that permits travelers to carry up to three portable earth-station transceivers that have not been authorized by FCC certification into the United States as personal effects for purposes other than sale or lease. The purposes of the new certification requirement for portable GMPCS transceivers are to prevent interference, reduce radio-frequency radiation exposure risk, and make regulatory treatment of portable GMPCS transceivers consistent with treatment of similar terrestrial wireless devices, such as cellular phones. The Second Report and Order also revises several rule provisions to place appropriate legal responsibility for unauthorized transceiver operation on parties that control access to satellite networks and to eliminate redundant information-filing requirements.

In addition to adopting rules pertaining to equipment authorization and importation of portable earth-station transceivers, the Second Report and Order amended a rule section that prescribes limits on emissions from Mobile Satellite Service transceivers in the 1559-1610 MHz band. In light of comments filed in response to a Further Notice of Proposed Rulemaking released in 2002, the Commission prescribed several additional limits on such out-of-band emissions, specified measurement techniques, and set compliance deadlines for Inmarsat maritime transceivers. These rule changes improve interference protection for aeronautical radio-navigation.

The Second Report and Order imposes new information collection requirements subject to the Paperwork Reduction Act of 1995 (PRA), Public Law 104-13. It has been submitted to the Office of Management and Budget (OMB) for review under section 3507(d) of the PRA. OMB, the general public, and other Federal agencies are invited to comment on the new information collection requirements.

Paperwork Reduction Act

The Second Report and Order imposes new information collection requirements. The Commission, as part of its continuing effort to reduce paperwork burdens, invites the general

[[Page 5708]]

public to comment on the information collection requirements as required by the Paperwork Reduction Act of 1995, Public Law 104-13. Public and agency comments on the information collection requirements are due April 6, 2004.

Final Regulatory Flexibility Analysis

The Regulatory Flexibility Act of 1980, as amended (RFA), requires that a regulatory flexibility analysis be prepared for notice-and- comment rule making proceedings, unless the agency certifies that ``the rule will not, if promulgated, have a significant economic impact on a substantial number of small entities.'' 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 Small Business Administration (SBA).

As proposed in a Notice of Proposed Rulemaking (NPRM) issued in 1999, the Second Report and Order in IB Docket No. 99-67 amends the Commission's rules to require authorization to be obtained in advance for importation, domestic sale or lease, or offering, shipment, or distribution for domestic sale or lease of portable, land-based earth- station transceivers. The authorization procedure, which is specified in previously adopted provisions in part 2 of the Commission's rules, requires submission of test data proving compliance with the Commission's pertinent technical requirements. The Notice of Proposed Rulemaking included an Initial Regulatory Flexibility Analysis (IRFA) pertaining to the proposed equipment-authorization requirement and invited comment on alternative authorization procedures that might minimize economic impact on small entities. The comments filed in response to the NPRM did not discuss the IRFA.

To obtain authorization required under the new rules for importation, distribution, or sale of portable, land-based earth- station transceivers, test data must be submitted to prove that the devices meet pertinent technical requirements in the Commission's rules. Because such testing would be necessary in any event to ensure that the devices can be lawfully operated in compliance with existing rule requirements, the Commission does not believe that the requirement to submit test data will have a significant adverse economic impact on anyone. The Commission postponed the effective date of the authorization requirement for one year, moreover, to afford adequate time in advance for obtaining such authorization and for disposing of uncertificated devices in current inventories. The Commission therefore certified that the equipment authorization requirement established by this order will not have significant economic impact on a substantial number of small entities.

The Second Report and Order also amends a rule section adopted in 2002, 47 CFR 25.216, that specifies out-of-band emission limits for mobile earth-station transceivers licensed to transmit in frequencies between 1610 MHz and 1660.5 MHz or in the 2 GHz MSS band. Specifically, the Second Report and Order amends Sec. 25.216 by prescribing a limit for carrier-off emissions, prescribing limits on narrowband emissions in the 1605-1610 MHz band, prescribing a stricter limit on wideband emissions in that band for transceivers with assigned frequencies between 1626.5 MHz and 1660.5 MHz, re-specifying the time interval for emission measurements, requiring use of RMS detectors for compliance testing, and specifying compliance deadlines for Inmarsat Standard-A and Standard-B terminals.

These changes were proposed in a Further Notice of Proposed Rulemaking released with the order that initially adopted Sec. 25.216 or in public comments filed in response to that Notice. As required by the RFA, the Further NPRM included an IRFA pertaining to these further rulemaking proposals. The Commission sought written public comment on the proposals and on the IRFA. This Final Regulatory Flexibility Analysis (FRFA) conforms to the RFA.

Rulemaking Objectives

The general purposes of the amendments to Sec. 25.216 are to modify its provisions to better serve the objective of preventing interference with aircraft reception of satellite radio-navigation signals and establish equitable compliance deadlines for Standard A and Standard B Inmarsat earth-station transceivers.

Summary of Issues Raised by Public Comments in Response to the IRFA

No comments were filed specifically in response to the IRFA in the Further NPRM.

Description and Estimate of the Number of Small Entities to Which the New Rules Will Apply

The RFA directs agencies to describe, and, where feasible, estimate the number of, small entities that may be affected by the rules they adopt. 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 Small Business Administration (SBA). For satellite telecommunication carriers and resellers, the SBA has established a small business size standard that excludes companies with annual receipts above $12.5 million.

The amended emission limits in Sec. 25.216 directly affect parties with licenses for operation of mobile earth stations subject to those limits, including owners of maritime vessels equipped with Standard A or Standard B Inmarsat transceivers. The Commission noted in the IRFA that ten companies held relevant blanket licenses and that four of them had annual revenue in excess of $12.5 million but could not determine from available information whether any of the others were small entities. The Commission anticipates that blanket licenses will be issued within the next three years for 2 GHz MSS earth stations subject to Sec. 25.216, but the Commission does not know how many of the recipients will be small entities. The SBA classifies commercial providers of water transportation (other than for sightseeing) as small entities if they have 500 or fewer employees. Of 1,627 providers of non-sightseeing water transportation counted in the 1997 U.S. Census that operated throughout the year, only 157 had more than 100 employees. The SBA classifies providers of sightseeing transportation by water as small entities if their annual receipts are $6 million or less. Of 1,692 providers of sightseeing transportation by water counted in the 1997 census, only 32 had annual receipts in excess of $6 million. Hence the Commission assumes that most owners of vessels equipped with Standard A or Standard B Inmarsat transceivers are small entities.

[[Page 5709]]

Reporting, Recordkeeping, and Other Compliance Requirements for Small Entities

The amended provisions of section 25.216 do not impose reporting or recordkeeping requirements. Parties with licenses for operation of mobile earth stations subject to section 25.216 will be obliged to ensure that the devices perform in compliance with the amended emission limits adopted in this order, however. Some licensees may find it necessary to alter, replace, or decommission equipment currently in service in order to comply with the amended limits. We do not know, nor do the comments filed in this proceeding indicate, how much additional expense licensees will incur to achieve compliance with the amended limits.

Steps Taken To Minimize Economic Impact on Small Entities and Significant Alternatives Considered

The RFA requires an agency to describe any significant alternatives considered that might reduce the economic impact on small entities, such as establishing different compliance or reporting requirements or timetables that take into account the resources available to small entities; clarifying, consolidating, or simplifying such requirements for such small entities; using performance rather than design standards; or completely or partially exempting small entities from new requirements.

We have considered and adopted exemptions for the benefit of ship owners--most of which, we presume, for reasons stated previously, are small entities. To minimize the impact on ship owners using Inmarsat Standard A transceivers as Global Maritime Distress and Safety System (``GMDSS'') stations, we exempt such devices from the requirements of Sec. 25.216 until December 31, 2007, the planned termination date for Standard A services. To minimize the impact on ship owners using Inmarsat Standard B transceivers as GMDSS stations, we exempt such transceivers manufactured previously or within six months hereafter from pertinent Sec. 25.216 limits until December 31, 2012, subject to a no-interference condition.

Report to Congress: The Commission will send a copy of the Second Report and Order, including this final RFA analysis, in a report to Congress pursuant to the Congressional Review Act. In addition, the Commission will send a copy of the Second Report and Order and the final RFA analysis to the Chief Counsel for Advocacy of the SBA.
