More Standards Emerge for 3.5 GHz CBRS

July 6, 2017 — 

The Wireless Innovation Forum has completed its Spectrum Sharing Committee’s (SSC) second version of the signaling protocols and procedures to be used in the U.S. 3.5 GHz Citizens Broadband Radio Service (CBRS) band for the Spectrum Access System (SAS) – Citizens Radio Broadband Service Device (CBSD) Interface.

The Spectrum Sharing Committee was created to develop standards that encourage the development of the CBRS ecosystem and protect incumbent operations. The SSC includes wireless carriers, network equipment manufacturers, potential SAS administrators, satellite operators and existing 3650-3700 MHz band licensees. Participation in the committee’s sub-groups and task groups includes near 280 representatives from more than 60 organizations.

  • The document, WINNF-16-S-0016 Signaling Protocols and Procedures for Citizens Broadband Radio Service: Spectrum Access System – Citizens Broadband Radio Service Device Interface Technical Specification, can be downloaded here: http://bit.ly/2rIKOxS.

This version of the SAS-CBSD protocol specification completes the work on this protocol for Release-1 of the WInnForum CBRS specifications. This specification defines the crucial protocols and operating procedures that are used between the Spectrum Access System (SAS) and the Citizens Broadband Service Device (radio base station).

Foundational documents published in the past year are available here: http://www.wirelessinnovation.org/ssc-public-files.  Access to spectrum under the Part 96 rules is managed in the CBRS band through the use of a Spectrum Access System, which protects incumbents from interference from lower tier priority access license and general authorized access users, and protects PAL users from interference from other PAL users and GAA users.

Begun early in 2015, the Spectrum Sharing Committee includes five working groups, each working on areas for the commercialization of the 3.5 GHz band, including: operational and functional requirements, security requirements, protocol specifications, testing and certification and operations.
