173. 2020-2025 MHz. Although we do not propose to modify the existing allocations in the 2020-2025 MHz band, we propose to remove footnote NG177 from the Allocation Table because Television Broadcast Auxiliary Stations have completed their transition from the 1990-2110 MHz band (120 MHz) to the 2025-2110 MHz band (85 MHz).
174. 2155-2180 MHz. We propose several modifications that relate to the 2155-2180 MHz band. Specifically, we propose to update and combine footnotes NG153 and NG178, and to tentatively number the resultant footnote as NG41. Specifically, we propose to remove the first two sentences from footnote NG153 (because we are not proposing to add any additional allocations to the 2160-2165 MHz band); to revise the last sentence in footnote NG153 by updating "Multipoint Distribution Service" and "emerging technologies" to read "Broadband Radio Service" and "Advanced Wireless Services," respectively; to highlight that all initial authorizations in the 2160-2180 MHz band applied for after January 16, 1992 were issued on a secondary basis; and to highlight the sunset provisions that apply to Part 101 fixed stations that were authorized on a primary basis. We propose to remove footnotes NG153, NG177, and NG178. The new footnote would be tentatively numbered NG41.
We also propose several non-substantive updates to the Table: (1) expand the cross reference to part 27 of the Commission's rules, which is shown as "Wireless Communications (27)" in the 1710-1755 MHz band, by displaying this cross reference in the 1695-1780 MHz band; and (2) revise the 1850-1980 MHz and 1980-2025 MHz bands in the Federal Table (which are not allocated for any Federal use) to read 1850-2000 MHz and 2000-2025 MHz. We also seek comment on any other allocation changes that would be necessary to effectuate any of the proposals contained in this Notice of Proposed Rulemaking.
175. 1.7 GHz Band. In the sections above, we seek comment on possible service rules for non-Federal, mobile use of 1755-1780 MHz on a shared basis with Federal users. Furthermore, NTIA has suggested that commercial use be considered in the full 1755-1850 MHz band. Our determination of whether such use should be permitted would be based on whether it serves the public interest, convenience, and necessity. We expect that the record in this proceeding will include recommendations from NTIA informed by the CSMAC process. In the event that the record supports a conclusion that non-Federal terrestrial service rules are appropriate for any of the 1.7 GHz band spectrum currently allocated for Federal use, what changes to the Table of Frequency Allocations would be necessary to implement such a conclusion in the 1.7 GHz band? Would different changes be required for different band segments and/or geographical locations? Could different portions of the band be allocated for shared or exclusive use?
176. Other Bands, including 2025-2110 MHz and 5150-5250 MHz. Throughout this notice, we seek comment on potential changes to Federal and non-Federal uses in several different bands. For instance, in paragraph 39 above, we seek comment on CTIA's proposal for commercial use of the 2095-2110 MHz band. NTIA notes that the Department of Defense has identified the 2025-2110 MHz band as the preferred option to relocate most of its operations and that the National Aeronautics and Space Administration and DoD have identified the 5150-5250 MHz band as a comparable destination band for their aeronautical mobile telemetry systems). NTIA adds that, "[i]f it is determined that agencies will need to relocate any of these systems, the FCC and NTIA will need to identify replacement spectrum and take necessary steps to enable comparable capabilities." More recently, NTIA transmitted a proposal from DoD that would require increased Federal access to the 2025-2110 MHz band, but not the 5150-5250 MHz band. We therefore seek comment on any changes to the Table of Frequency Allocations that would be necessary to effectuate these and any other band reconfiguration concepts identified in this notice or proposed alternatives. We note that in contrast to non-Federal terrestrial allocations, where the issuance of service rules is typically required prior to the issuance of licenses, the addition of a Federal allocation to a band typically allows the authorization of new Federal assignments without an intermediate step. In other words, once the Federal allocation is in place, NTIA could immediately begin issuing spectrum assignments. Therefore, if the record should demonstrate the public interest in accommodating new Federal systems through allocation changes, we seek comment on whether, and if so how, any new Federal allocations be made contingent on relocation to accommodate new commercial licensees in the 1.7 GHz band.
