Spectrum Access System unveils new feature to enhance CBRS spectrum availability near the coast
Spectrum Access System is excited to announce support of CBRS 2.0, a set of changes to interference protection to Federal incumbents that significantly improves the availability of Citizens Broadband Radio Service (CBRS) spectrum near the coast. With this feature, Spectrum Access System will be able to authorize service to approximately 72 million more people (for a total of approximately 240 million) nationwide without periodic service interruptions to protect federal operations, while also providing greater spectrum access within DPA neighborhoods due to fewer and less frequent grant suspensions.
Check the CBRS overlays in SAS Portal to see the new DPA neighborhoods. You will also notice a number of CBSD grants are no longer in movelists. These changes are a major breakthrough for SAS users, as it will open up a significant amount of new spectrum for use. This will benefit a wide range of applications, including fixed wireless broadband, public safety communications, and private networks.
The Spectrum Access System team is committed to providing our users with the best possible experience, and we believe that CBRS 2.0 will be a valuable addition to our platform. We are excited to see how our users will use this new feature to innovate and create new solutions.
For more information about operating CBSDs near the coast, see our Overview of CBSD concepts.

Hawaii CBRS channel availability update

January 2024
The following features have been added to SAS this month:
Enhanced spectrum availability (EIRP Upgrade)
SAS can now automatically check whether grants approved with a certain Effective Isotropic Radiated Power (EIRP) value during the day are eligible for an EIRP increase after the Coordinated Periodic Activities among SASs (CPAS) window has passed, provided they meet eligibility requirements. Citizens Broadband Radio Service Device (CBSD) operators are encouraged to reach out to their vendors to confirm support for the new EIRP upgrade feature. Interoperability tests for this feature are available to vendors to validate that CBSDs are using the higher EIRP. For more information on this feature, see our announcement on the Community Forum.
Heartbeat extension
The
transmitExpireTimevalue for grants outside of Dynamic Protection Area (DPA) neighborhoods has been extended from 4 minutes to 6 hours. Grants that are in the upper50 MHz (3650-3700 MHz) range will also get this extended expiration window, even if located inside DPA neighborhoods. Early access to this feature is available. For more information on this feature, see our announcement on the Community Forum.
