The CBRS Alliance specification for Network and Coexistence Release 2 has been finalized and published.

The CBRS Alliance supports the development, commercialization and adoption of OnGo LTE and 5G platforms for Citizens Broadband Radio Service in the 3.5 GHz spectrum. The releases are part of the preparation for OnGo.

“As the Initial Commercial Deployment phase quickly approaches, a solid framework is in place to support efficient connection and traffic management on the band,” CBRS Alliance Executive Director Alan Ewing said in a press release. “The innovative, industry-leading work represented in Release 2 is setting the foundation for a new standard of wireless connectivity.”

The specifications for coexistence, which are built on the baseline specs released last year, are designed to ensure compatibility across CBRS devices. Release 2 addresses enhanced network functionality in fixed access, private, shared and mobile broadband network scenarios. New features include shared network identifiers, enhanced security features including authentication and support for mobility capabilities such as roaming into private and neutral host networks, according to the alliance.

The specifications are an important development, the alliance says. “The new specifications refine existing standards and further ensure the success of LTE-based OnGo deployments,” Gary Boudreau, the Chair of the CBRS Alliance’s technical Working Group, said in the press release. “OnGo supports a variety of deployment types, including private LTE, neutral host networks, and more, and each require appropriate authentication and channelization standards. Network operators, device manufacturers, and end users can expect a seamless transition to high-quality OnGo networks when the FCC authorizes wide-scale commercial use of the band this year.”

Enhanced coexistence functionality also has been added. It helps mitigate interference among general access (GAA) users. It includes alignment of signal configurations, measurement frameworks to quantify GAA interference and messaging protocol enhancements to support coordination of GAA users.
