FCC WRC-12 Notice of Proposed Rulemaking (FCC 15-50)
|
In the Notice of Proposed Rulemaking (WRC-12 Notice), we propose to amend Parts 2, 15, 80, 90, 97, and 101 of the Commission’s rules to implement allocation decisions from the WRC-12 Final Acts and make certain updates to our rules. Specifically, we propose to:
• Allocate the 8.3-11.3 kHz band to the meteorological aids service on a primary basis.
• Allocate the 472-479 kHz band (630 meter band) to the amateur service on a secondary basis.
• Amend the amateur service rules to provide for use of the 135.7-137.8 kHz (2200 meter) and 472-479 kHz (630 meter) bands. Amateur stations would share the band with power line carrier (PLC) systems operated by electric utilities. Amateur stations would be permitted to operate in these bands at fixed locations when separated from electric transmission lines by a specified distance.
• Amend Part 80 of the Commission’s rules to authorize radio buoy operations in the 1900-2000 kHz band under a ship station license.
• Limit the use of the 495-505 kHz band to the maritime mobile service.
• Allocate seven frequency bands (4.438-4.488 MHz, 5.25-5.275 MHz, 16.1-16.2 MHz, 24.45-24.65 MHz, 26.2-26.42 MHz, 41.015-41.665 MHz, and 43.35-44 MHz) to the radiolocation service (RLS) on a primary basis for Federal and non-Federal use, allocate the 13.45-13.55 MHz band to the RLS on a secondary basis for Federal and non-Federal use, limit the use of these RLS allocations to oceanographic radars, require that these radars not cause harmful interference to, or claim protection from, existing and future stations in the incumbent fixed and mobile services, and amend Part 90 of the Commission’s rules accordingly.
• Reallocate the 156.7625-156.7875 MHz (AIS 3) and 156.8125-156.8375 MHz (AIS 4) bands to the MSS (Earth-to-space) on a primary basis for Federal and non-Federal use to allow for greater probability of vessel tracking, with resulting benefits to maritime safety and security.
• Seek comment on the ability of Federal/non-Federal AMT stations to share spectrum with the incumbent services in the 4400-4940 MHz and 5925-6700 MHz bands.
• Extend the AM(R)S allocation from the 5091-5150 MHz band (adopted in the WRC-07 R&O) by also allocating the 5000-5091 MHz range to the AM(R)S on a primary basis for Federal and non-Federal use. AM(R)S use of the smaller 5000-5030 MHz range would extend the tuning range for AeroMACS, with the use of the 5010-5030 MHz band limited to those requirements that cannot be meet in the 5000-5010 MHz and 5091-5150 MHz bands. AM(R)S use of the 5030-5091 MHz band would support line-of-sight control links for unmanned aircraft.
• Allocate the 7850-7900 MHz band to the meteorological-satellite service (space-to-Earth) on a primary basis for Federal use.
• Allocate the 15.4-15.7 GHz band to the RLS on a primary basis for Federal use.
• Allocate the 22.55-23.15 GHz band to the space research service (SRS) (Earth-to-space) on a primary basis for Federal and non-Federal use and allocate the 25.5-27 GHz band to the SRS (space-to-Earth) on a primary basis for non-Federal use.
• Delete the aeronautical mobile service allocation from the 37-38 GHz band.
• Encourage operators of fixed stations operating in the 81-86 GHz and 92-94 GHz bands to take all reasonable steps to ensure that their unwanted emissions power in the 86-92 GHz band does not exceed the levels recommended by WRC-12.

Spectrum Rules and Policies for the Operation of Unmanned Aircraft Systems, Report and Order
|
In this Report and Order, we enable UAS operators to access dedicated spectrum for control-related communications with the required reliability. Specifically, we adopt new UAS service rules under new rule part 88 that provide operators the ability to obtain direct frequency assignments in a portion of the 5030-5091 MHz band. Under these rules, one or more dynamic frequency management systems (DFMSs) will manage and coordinate access to the spectrum and enable its safe and efficient use, by providing requesting operators with temporary frequency assignments to support UAS control link communications with a level of reliability suitable for operations in controlled airspace and other safetycritical circumstances. To provide this level of safety and reliability, we are adopting technical requirements drawn from minimum operational performance standards that were developed by an aviation industry standards body specifically to support UAS control links in the 5030-5091 MHz band and were approved by the Federal Aviation Administration (FAA) for this purpose. To address concerns regarding the impact of these aeronautical operations on adjacent services, we locate these operations, for now, in the central part of the band, with substantial separation from the bands adjacent to the 5030-5091 MHz band. We find wide support for enabling early, direct access to a portion of the band for protected assignments under DFMS coordination, and anticipate that such access will facilitate the safe integration of UAS operations into the NAS so that the United States can realize the enormous potential benefits that UAS operations can provide.

FCC 5 GHz U-NII Notice of Proposed Rulemaking (FCC 13-22)
|
By this Notice of Proposed Rulemaking (NPRM), we propose to amend Part 15 of our
rules governing the operation of Unlicensed National Information Infrastructure (U-NII) devices in the 5
GHz band.1 U-NII devices are unlicensed intentional radiators that operate in the frequency bands 5.15-
5.35 GHz and 5.47-5.825 GHz, and which use wideband digital modulation techniques to provide a wide
array of high data rate mobile and fixed communications for individuals, businesses, and institutions.
Since the Commission first made available spectrum in the 5 GHz band for U-NII in 1997, we have
gained much experience with these devices. We believe that the time is now right for us to revisit our
rules, and, in this NPRM, we propose to modify certain technical requirements for U-NII devices to
ensure that these devices do not cause harmful interference and thus can continue to operate in the 5 GHz
band and make broadband technologies available for consumers and businesses.
We also seek comment on making available an additional 195 megahertz of spectrum in
the 5.35-5.47 GHz and 5.85-5.925 GHz bands for U-NII use. This could increase the spectrum available
to unlicensed devices in the 5 GHz band by approximately 35 percent and would represent a significant
increase in the spectrum available for unlicensed devices across the overall radio spectrum. The initiation
of this proceeding satisfies the requirements of Section 6406 (a) of the "Middle Class Tax Relief and Job
Creation Act of 2012” which requires the Commission to begin a proceeding to modify part 15 of title 47,
Code of Federal Regulations, to allow unlicensed U-NII devices to operate in the 5350-5470 MHz band.
We believe that an increase in capacity gained from 195 megahertz of additional spectrum, combined
with the ease of deployment and operational flexibility provided by our U-NII rules, would continue to
foster the development of new and innovative unlicensed devices, and increase wireless broadband access
and investment.
