3550-3650 MHz

The National Telecommunications and Information Administration (NTIA) October 2010 Fast Track Report identified the 3550-3650 MHz band (3.5 GHz Band) as potentially suitable for commercial broadband use. In 2015, the Federal Communications Commission (FCC) established the new Citizens Broadband Radio Service (CBRS) in the 3.5 GHz Band and created a three-tiered framework to coordinate shared federal and non-federal use of the band.  NTIA has worked closely with the FCC and the Department of Defense to make the band suitable for commercial operation while protecting U.S. Navy uses for radar systems on its ships. Most notably, NTIA engineers, working with the FCC and DoD, have been successful in significantly reducing large exclusion zones along the coastlines and around selected ground-based radar sites through the creation of Dynamic Protection Areas (DPAs) made possible by groundbreaking analysis and modeling techniques. DPAs, along with the Spectrum Access System (SAS) that tracks locations of radio transmitters and controls their operation, and an Environmental Sensing Capability (ESC) that detects the presence of signals from specified sources, are poised to deliver an innovative spectrum sharing framework that will maximize the commercial market potential for new broadband services, while protecting essential incumbent federal operations and satellite services.
