January 09, 2023

Google SAS no longer enforces Part 90 of the Grandfathered Wireless Protection Zone (GWPZ) regulations. This change opens more spectrum for CBRS usage in the 3650-3700 MHz range, particularly in Texas and Louisiana.

  • CBSDs that were located within GWPZs can now use the upper 50 MHz of the range.
  • CBSDs within 40km of GWPZs now have EIRP restrictions removed when requesting grants (if no other incumbent limitations are present).

In order to take advantage of the potentially higher EIRP, CBSDs must perform a spectrum Inquiry to check available EIRP or otherwise request new grants. For more information on how to perform a Spectrum Inquiry, see Best Practices. This feature is Generally Available (GA).

November 10, 2022

The CBSDs can now operate in the 3650–3700 MHz portion of the CBRS band in the 150 km area around fixed-satellite service (FSS) receive-only earth stations. The 150 km area around each FSS for 3650-3700 MHz that was considered an exclusion zone is now a protection zone. For more information on how to access the CBRS heatmaps, see CBRS heatmaps.

This feature is Generally Available (GA).
