CLASSIFICATION Conditions* for Surrender of DoD Spectrum

1. NTIA, in consultation with the FCC, has identified and made available to the Department of Defense for its primary use, if necessary, an alternative band or bands of frequencies with comparable technical characteristics as a replacement

2. The Secretary of Commerce, the Secretary of Defense, and the Chairman of the Joint Chiefs of Staff have jointly certified to the Committee on Armed Services and the Committee on Commerce, Science and Transportation of the Senate; and the Committee on Armed Services and the Committee on Commerce of the House of Representatives, that the replacement band or bands of frequencies provides comparable technical characteristics to restore essential military capability that will be lost when the band of frequencies is surrendered.

95 MHz of Unrestricted FIXED and MOBILE spectrum supports Army operations, training, and testing.

• NTIA Must Provide Comparable Spectrum to Allow Army and other Federal Agencies to Relocate to Alternate Spectrum Bands

• Comparable Spectrum Means:– Equivalent Radiocommunications Service Allocation and Status– Similar Amount of Allocated Bandwidth– Suitable Technical and Operational Characteristics

• Supports Equipment Design and Operational Constraints• Feasibility of Coexisting with Systems Currently in the Band• No loss of essential military capability

Although these bands have the required Federal FIXED allocation, the higher propagation path loss and the potential for greater fading losses will impact the reliability of links having long path lengths (e.g., 20-30 mi). Consequently, this spectrum is less desirable for relocation of FIXED systems.

The Army’s AN/GRC-245 requires a minimum 50 MHz transmit-receive frequency separation which is not supported by this 40-MHz wide band. Spectrum support in a paired band, such as the 1435-1525 MHz band would also be needed to address this requirement.
