Abstract: As part of its ongoing effort to identify candidate bands for repurposing to accommodate commercial wireless services, NTIA selected the 3450-3550 MHz band to study for potential sharing between federal systems and a variety of non-federal commercial wireless operations. NTIA worked with the Department of Defense (DOD), which operates the federal systems in the band, to determine the conditions needed to enable commercial services to operate without causing impact to incumbent operations. The report indicates that commercial operations would impact incumbent federal systems; however, spectrum sharing that provides both sufficient protection to incumbent operations and an attractive commercial business case may be possible with further information and analysis, including studying the efficacy of deploying appropriate time-based sharing mechanisms.
