1. Preliminary Spectrum Relocation Options forArmy Systems in the 1755 – 1850 MHz Bandpresented to theArmy 1755 – 1850 MHz Spectrum RelocationWorkshop by Dennis Stewart (dstewart@alionscience.com) Army CIO/G-6, ASMO 1 February 2011

2. Outline • Conditions for Replacement Spectrum • Characterizing Comparable Replacement Spectrum • Spectrum Relocation Options for Major Categories of Army Systems • Summary

3. Conditions* for Surrender of DoD Spectrum • 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 • 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. *Source: Title X, Subpart G, Section 1062 of the National Defense Authorization Act for Fiscal Year 2000

4. Present Frequency Allocation of the1755-1850 MHz Band • 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 *Note: Primary service allocations are shown in all capital letters (i.e., FIXED) Secondary service allocations are shown in initial capital letters (i.e., Fixed)
