16. 1755-1850 MHz. NTIA established CSMAC Working Groups 2-5, comprised of representatives and experts from industry and Federal agencies, to facilitate information sharing among the interested stakeholders. In May 2012, NTIA asked each CSMAC working group to focus on the following tasks:
* Working Group 2 (WG2) (Law Enforcement Surveillance, Explosive Ordnance Disposal (EOD), and other short distant links)--the correlation of agency city-by-city transition plans with industry implementation priorities, and prioritizing vacating the 1755-1780 MHz sub-band;
* Working Group 3 (WG3) (Satellite Control and Electronic Warfare)--the definition and specification (including any interference acceptance rules) of zones around satellite sites, and coordination path rules for electronic warfare development and training;
* Working Group 4 (WG4) (Tactical Radio and Fixed Microwave)--the definition and specification (including any interference acceptance rules) of zones around Department of Defense sites that require access, and relocation process of fixed microwave links starting from 1755-1780 MHz; and
* Working Group 5 (WG5) (Airborne Operations (Air Combat Training System, Unmanned Aerial Vehicles, Precision-Guided Munitions, Aeronautical Telemetry))--the determination of protection requirements for Federal operations and understanding of the periodic nature of airborne operations and the impact to commercial wireless systems from government airborne operations.
17. Of the four working groups concentrating on the 1755-1850 MHz band, only WG2 has issued a final report, which the full CSMAC adopted on February 21, 2013. The WG2 Final Report found that Federal incumbents with video surveillance systems plan to transition operations from the 1755-1780 MHz band within five years, once funding and comparable spectrum is available. WG2 also developed two lists of areas for agencies with transitioning video surveillance systems to consider based on priorities established by the wireless industry. The first list addresses the 1755-1780 MHz band, while the second list addresses the 1780-1850 MHz band. On April 19, 2013, NTIA endorsed the recommendations contained in the WG2 Final Report.
18. In addition to the work of the CSMAC working groups, commercial wireless carriers are working with the Department of Defense (DoD) to monitor and gather information about several systems identified in NTIA's 1755-1850 MHz Assessment Report that appear to be the most difficult, costly, or time consuming to relocate. The carriers also requested special temporary experimental authority from the Commission to conduct tests in the 1755-1780 MHz and 2155-2180 MHz bands for commercial mobile broadband services, and to examine technical co-existence with a limited number of incumbent Federal operations, in a defined number of geographic locations that may remain in the band indefinitely, consistent with the CSMAC working groups' efforts. On August 14, 2012, the Commission announced that it had granted the first authorization of testing in the 1755-1780 MHz band.
19. We are advancing proposals in today's NPRM in tandem with NTIA's work to ensure that the statutory deadline under Section 6401 of the Spectrum Act can be met, and in light of the importance of making needed spectrum available as soon as practicable. Today's proposals are subject to revision in light of the recommendations we receive from NTIA after its evaluation of the output of these working groups. We intend to incorporate NTIA's forthcoming recommendations into the record of this proceeding and anticipate that commenters will discuss NTIA's recommendations in comments, reply comments, or ex parte presentations, as appropriate, depending on the timing.
