ESC-controlled DPA. These DPAs are located along the coasts of all US states and territories and are protected in the 3550-3650 MHz range.
- Where ESCs are deployed: When incumbent activity is detected, grants that cause excess interference to the DPA will be suspended, while those that cause minimal interference will remain in their current state. When there is no incumbent activity, grants aren't affected.
- Where ESCs aren't deployed: Grants that exceed the interference margin to E-DPAs are always suspended. Learn about areas with limited CBRS spectrum.
