Google Cloud will stop accepting new customers for its CBRS spectrum access system on June 10, 2026, and fully retire the service by June 10, 2027. Existing users must migrate their CBRS deployments to alternative SAS providers like Federated Wireless, Red Technologies, Nokia, Sony, or Keybridge.

• Google Cloud is shutting down its CBRS SAS service—new signups stop June 10, 2026, full retirement June 10, 2027—forcing existing customers to migrate to Federated Wireless, Red Technologies, Nokia, Sony, or Keybridge.
• CBRS adoption is contested: a CTIA-backed report calls it underused and wasteful, while industry players counter with 285,000+ deployed base stations/devices (including 10,000 from cellular operators) and Federated Wireless alone managing 45% of ~400,000 CBRS devices.
• Google's exit leaves one fewer original SAS administrator (down from CommScope, Federated Wireless, Google, and Sony) in a market already facing questions about the technology's viability.
