Google touts Spectrum Access System for 3.5 GHz spectrum management

Spectrum sharing was a theme at the International Symposium on Advanced Radio Technologies in Boulder (CO), and Google shared what it's been doing to enable the Federal Communications Commission's spectrum-sharing vision in the 3.5 GHz band. Google demonstrated the third version of the Spectrum Access System (SAS) it has built, which includes software running on Google infrastructure that is capable of dynamically managing the relationships among three proposed tiers of users at 3.5 GHz: federal and nonfederal incumbents, Priority Access Licensees and General Authorized Access users.

Google consistently has supported the use of interconnected SASs to manage coexistence in the 3.55 GHz bands. It has been running several wireless transmission sites at 3.5 GHz to develop and test the technology, and it has demonstrated its prototype SAS at previous FCC workshops and events.
