Enhancements to CBRS Baseline Standards (Release 2)


"This release is the beginning of bringing new functionality to the CBRS ecosystem; moving beyond the features required for regulatory compliance, to the features desired by users, operators, and suppliers to make CBRS more effective for their missions. We look forward to the continual enhancement of the WInnForum standards as they respond to CBRS experience, new technology, and the flexibility to innovate within the CBRS framework."
- Preston Marshall, Google

Throughout 2020, the Forum has continued to expand Release 2 specification enhancements to the baseline CBRS Operational and Functional Requirements. The resulting optional features and functionality can be incorporated at any time, with special focus on supporting specific vertical markets and their deployments.

To address backward compatibility with the WInnForum Release 1 Baseline Standards, the only mandatory feature in Release 2 for a SAS or CBSD is to support the feature capability exchange between SASs and CBSDs. Based on the Release 2 additions, exciting emerging technologies can be considered and implemented. 

Additional emerging technologies can be considered in subsequent releases.  Details can be found in the Release Plan hereCBRS Baseline Standards (Release 1) can be found here.
