The FCC last week considered proposed options for where to reloca...

rules for 2 blocks of 45 MHz spectrum, including the 1710-1755 MHz that the Dept. of Defense agreed to clear for advanced services such as 3G. The other block was 45 MHz of the 2110-2170 MHz now occupied by nongovt. users. In its latest rulemaking, the FCC proposed to: (1) Let DoD use 2025-2110 on a co-equal, co-primary basis with nonfederal govt. operations for earth stations at 11 sites that supported military space operations. (2) Roll back the recent establishment of Wireless Communications Services (WCS) at 2385-2395 MHz, let federal and nonfederal flight test stations operate at 2385-2395 MHz and no longer make 2390-2400 MHz available for use by unlicensed PCS devices. That 2nd change would allow DoD to relocate all aeronautical mobile systems out of 1710-1755 MHz, “which is a major objective for facilitating the introduction of AWS.” The proposal said that over time DoD access to 2025-2110 MHz for uplinks for military space operations -- known as tracking telemetry and command operations -- could make more spectrum available at 1755-1850 MHz for “absorbing certain DoD systems displaced from the band 1710-1755 MHz.” The plan would permit military services to use fixed and mobile stations, except aeronautical mobile services, at 2025-2110 MHz, on a secondary basis at 6 sites in the Southwest. As part of those spectrum relocation possibilities, which look for places to move federal users to in spectrum that’s under the purview of the FCC, the WCS and unlicensed PCS proposals would provide replacement spectrum for DoD and commercial flight test stations, the Commission said. Those stations may lose access to 35 MHz at 1525-1535 MHz and 2320-2345 MHz shortly. The Commission said it licensed 2025-2110 MHz to Broadcast Auxiliary Service (BAS). During the comment period, NAB and MSTV told the FCC they didn’t oppose the idea of relocating some federal operations to the band as long as broadcasters weren’t deprived of essential BAS services. “We believe that this action would provide a reasonable opportunity for clearing the band 1710-1755 MHz for new nationwide AWS uses and that permitting DoD earth stations access to the band 2025-2110 MHz would also provide greater use of the band 2025-2110 MHz without a significant impact on incumbent operations,” the proposal said. The proposal is expected to have a minimal impact on unlicensed PCS use at 2390-2400 MHz, where federal and nonfederal use of 2390-2395 MHz is expected for a “limited” number of aeronautical telemetry ranges in remote areas. “We have reviewed our files and have found that no unlicensed PCS device has been authorized in the band 2390-2400 MHz,” the proposal said.
