摘 要：The Department of Commerce's National Telecommunications and Information Administration (NTIA) led an interagency group to determine the viability of accommodating commercial wireless broadband in the 1755-1850 MHz band. While the analyses summarized in this report indicates there are a number of challenges to repurposing, NTIA concludes that it is possible to repurpose all 95 megahertz of the band. This analysis results from an eight-month evaluation process led by NTIA and engaging, via the Policy and Plans Steering Group (PPSG), the predominant federal agency users of this band. Each federal agency analyzed and documented its ability to relocate systems, associated costs, and anticipated periods of transition. In conducting the analysis, NTIA and the federal agencies endeavored to protect critical federal operations from disruption and to reach comparable capability via other spectrum, commercial services, or means that do not utilize spectrum, where appropriate.
