I. Procedural Matters A. Paperwork Reduction Act Analysis 2. The order does not contain any new or modified information collection. B. Regulatory Flexibility Act 3. A Final Regulatory Flexibility Analysis has been prepared with respect to the Sixth Report and Order and is set forth below. C. Report to Congress 4. The Commission will send a copy of this Sixth Report and Order in a report to be sent to Congress and the General Accounting Office pursuant to the Congressional Review Act, see 5 U.S.C. 801(a)(1)(A). D. Supplemental Final Regulatory Flexibility Analysis 5. As required by the Regulatory Flexibility Act (RFA), a Final Regulatory Flexibility Analysis (FRFA) was incorporated in the Fifth Report and Order in WT Docket 96-86. The Commission sought written public comment on the proposals in the Fifth Notice of Proposed Rulemaking. [[Page 21664]] E. Final Regulatory Flexibility Certification 6. The Regulatory Flexibility Act (RFA) requires that an agency prepare a regulatory flexibility analysis for notice-and-comment rulemaking 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 ``small entity'' as having the same meaning as the terms ``small business,'' ``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). 7. In this Sixth Report and Order, we: Revise values in the emission limit tables set forth at 47 CFR 90.543 to ensure technological feasibility; Delete the column entitled ``Maximum ACCP (dbm)'' from the table governing ACCP requirements for mobile transmitter set forth at 47 CFR 90.543 because these values are inconsistent with the Commission's decision not to require mobile transmitters to utilize Automatic Power Control; Change the terminology ``Adjacent Channel Coupled Power'' to ``adjacent Channel Power'' in our Rules to align our rules with industry standards. 8. These changes, which are intended to ensure that the Commission's rules reflect the latest technical and industry standards, and to correct typographical or ministerial errors in the Commission's Rules, are exclusively of an administrative nature. The changes will not have a significant economic impact on small entities because they are technologically neutral and will affect all entities equally. 9. The Commission therefore certifies, pursuant to the RFA, that the rule changes contained proposals in this Sixth Report and Order will not have a significant economic impact on a substantial number of small entities. 10. The Commission will send a copy of the Final Analysis including a copy of this Final Regulatory Flexibility Certification, to the Chief Counsel for Advocacy of the SBA. This certification will also be published in the Federal Register. II. Ordering Clauses 11. Pursuant to Sections 4(i), 303(f), 332, 337 and 405 of the Communications Act of 1934, as amended, 47 U.S.C. 154(i), 303(f), 332, 337 and 405 this Sixth Report and Order is hereby adopted. 12. It is further ordered that the amendments of the Commission's Rules as set forth in Rule Changes are adopted May 27, 2005. 13. It is further ordered, that the Commission's Consumer and Governmental Affairs Bureau, Reference Information Center, shall send a copy of this Sixth Report and Order including the Final Regulatory Flexibility Analysis to the Chief Counsel for Advocacy of the Small Business Administration.

The following procedures are to be followed for making ACP transmitter measurements. For time division multiple access (TDMA) systems, the measurements are to be made under TDMA operation only during time slots when the transmitter is on. All measurements must be made at the input to the transmitter's antenna. Measurement bandwidth used below implies an instrument that measures the power in many narrow bandwidths (e.g., 300 Hz) and integrates these powers across a larger band to determine power in the measurement bandwidth. (i) Setting reference level. Using a spectrum analyzer capable of ACP measurements, set the measurement bandwidth to the channel size. For example, for a 6.25 kHz transmitter, set the measurement bandwidth to 6.25 kHz; for a 150 kHz transmitter, set the measurement bandwidth to 150 kHz. Set the frequency offset of the measurement bandwidth to zero and adjust the center frequency of the spectrum analyzer to give the power level in the measurement bandwidth. Record this power level in dBm as the ``reference power level''. (ii) Non-swept power measurement. Using a spectrum analyzer capable of ACP measurements, set the measurement bandwidth as shown in the tables above. Measure the ACP in dBm. These measurements should be made at maximum power. Calculate the coupled power by subtracting the measurements made in this step from the reference power measured in the previous step. The absolute ACP values must be less than the values given in the table for each condition above. (iii) Swept power measurement. Set a spectrum analyzer to 30 kHz resolution bandwidth, 1 MHz video bandwidth and sample mode detection. Sweep MHz from the carrier frequency. Set the reference level to the RMS value of the transmitter power and note the absolute power. The response at frequencies greater than 600 kHz must be less than the values in the tables above. (3) Out-of-band emission limit. On any frequency outside of the frequency ranges covered by the ACP tables in this section, the power of any emission must be reduced below the unmodulated [[Page 21666]] carrier power (P) by at least 43 + 10 log (P) dB. (4) Authorized bandwidth. Provided that the ACP requirements of this section are met, applicants may request any authorized bandwidth that does not exceed the channel size. * * * * * PART 90--PRIVATE LAND MOBILE RADIO SERVICES 0 3.

Section 90.543 is revised to read as follows: Sec. 90.543 Emission limitations. Transmitters designed to operate in 764 776 MHz and 794 806 MHz frequency bands must meet the emission limitations in this section. (a) The adjacent channel power (ACP) requirements for transmitters designed for various channel sizes are shown in the following tables.

The following are the procedures for making the transmitter ACP measurements. For all measurements modulate the transmitter as it would be modulated in normal operating conditions. For time division multiple access (TDMA) systems, the measurements are to be made under TDMA operation only during time slots when the transmitter is active. All measurements are made at the transmitter's output port. If a transmitter has an integral antenna, a suitable power coupling device shall be used to couple the RF signal to the measurement instrument. The coupling device shall substantially maintain the proper transmitter load impedance. The ACP measurements may be made with a spectrum analyzer capable of making direct ACP measurements. ``Measurement bandwidth'', as used for non-swept measurements, implies an instrument that measures the power in many narrow bandwidths equal to the nominal resolution bandwidth and integrates these powers to determine the total power in the specified measurement bandwidth. (1) Setting reference level. Set transmitter to maximum output power. Using a spectrum analyzer capable of ACP measurements, set the measurement bandwidth to the channel size. For example, for a 6.25 kHz transmitter, set the measurement bandwidth to 6.25 kHz; for a 150 kHz transmitter, set the measurement bandwidth to 150 kHz. Set the frequency offset of the measurement bandwidth to zero and adjust the center frequency of the instrument to the assigned center frequency to measure the average power level of the transmitter. Record this power level in dBm as the ``reference power level''. (2) Non-swept power measurement. Using a spectrum analyzer capable of ACP measurements, set the mesurement bandwidth and frequency offset from the assigned center frequency as shown in the tables in Sec. 90.543 (a) above. Any value of resolution bandwidth may be used as long as it does not exceed 2 percent of the specified measurement bandwidth. Measure the power level in dBm. These measurements should be made at maximum power. Calculate ACP by substracting the reference power level measured in (b)(1) from the measurements made in this step. The absolute value of the calculated ACP must be greater than or equal to the absolute value of the ACP given in the table for each condition above. (3) Swept power measurement. Set a spectrum analyzer to 30 kHz resolution bandwidth, 1 MHz video bandwidth and average, sample, or RMS detection. Set the reference level of the spectrum analyzer to the RMS value of the transmitter power. Sweep above and below the carrier frequency to the limits defined in the tables. Calculate ACP by substracting the reference power level measured in (b)(1) from the measurements made in this step. The absolute value of the calculated ACP must be greater than or equal to the absolute value of the ACP given in the table for each condition above. (c) Out-of-band emission limit. On any frequency outside of the frequency ranges covered by the ACP tables in this section, the power of any emission must be reduced below the mean output power (P) by at least 43 + 10log (P) dB measured in a 100 kHz bandwidth for frequencies less than 1 GHz, and in a 1 MHz bandwidth for frequencies greater than 1 GHz. (d) Authorized bandwidth. Provided that the ACP requirements of this section are met, applicants may request any authorized bandwidth that does not exceed the channel size. (e) For operations in the 764 to 776 MHz and 794 to 806 MHz bands, all emissions including harmonics in the band 1559-1610 MHz shall be limited to -70 dBW/MHz equivalent isotropically radiated power (EIRP) for wideband signals, and -80 dBW EIRP for discrete emissions of less than 700 Hz bandwidth. For the purpose of equipment authorization, a transmitter shall be tested with an antenna that is representative of the type that will be used with the equipment in normal operation. (f) When an emission outside of the authorized bandwidth causes harmful interference, the Commission may, at its discretion, require greater attenuation than specified in this section.
