FCC puts final rules in place for spectrum sharing in 3.5 GHz band
April 28. 2016
The FCC today reaffirmed its decision to create the Citizens Broadband Radio Service (CBRS) in the 3.5 GHz band and took steps to finalize the rules for a new experimental sharing regime, making 150 MHz available for mobile broadband and other commercial uses.
The move today generally reaffirms the regulatory framework the commission adopted in the band in April 2015. FCC Commissioner Jessica Rosenworcel said the proceeding represents a "blueprint for the future of spectrum policy," ditching the notion that everyone must make a choice between licensed and unlicensed spectrum. "The impact of this band and this approach is bound to be big," she said.
The FCC's decision to adopt new spectrum sharing tools and policies for the 3.5 GHz band comes after the NTIA several years ago identified the band as suitable for shared use between government and commercial interests, provided existing incumbents, including the Department of Defense (DoD) and fixed satellite services, were given protection. The three-tiered access framework for the 3.5 GHz band includes an Incumbent Access tier, Priority Access tier and General Authorized Access tier. The three tiers are to be coordinated through a dynamic Spectrum Access System (SAS).
