Spectrum Access System (SAS)

Access to shared CBRS spectrum for all

Google SAS enables access to the CBRS band, effectively sharing spectrum among fixed wireless, mobile, and private network users to maximize bandwidth and transmit power.

New Google Cloud customers can use $300 in free credits to try out Google SAS.

Features

Reliability

Google SAS is built with multiple layers of reliability, including a distributed architecture that is optimized to maintain uninterrupted communications between SAS and CBRS devices.

EIRP optimization

Google SAS helps each of your CBSDs get the maximum transmit power available so that your network can offer the best performance to your users and customers.

Channel guidance and spectrum planning

Google SAS offers tools to discover the optimal radio frequencies, either in real time or during network planning. Google's high-resolution geo data is used to estimate power and interference on each channel, resulting in more available bandwidth, higher transmit power authorizations, and lower interference.

ESC network

Google SAS is powered by a Telco grade Environmental Sensing Capability (ESC) sensor network along the continental US coast and Hawaii (2024). Google ESC is designed for maximum coverage and redundancy to maximize spectrum availability near the coast.

Tools to manage your CBSD performance

Google SAS offers a user-friendly, map-based portal that makes it easy to find spectrum available, register CBSDs, and see the overall status of your network. Rich SAS-CBSD API communication logs are easy to explore in BigQuery for detailed troubleshooting, custom monitoring and insightful analytics and dashboards.

How It Works

On the Console, navigate to Spectrum Access System, enable service and define UR-ID for your network. Next, go to SAS portal, add your CPI to upload and sign device configuration, now register CBSDs with SAS and get access to CBRS spectrum. Use Cloud Monitoring and BigQuery to create alerts/dashboards.

Common Uses

Fixed wireless

Broadband networks using CBRS spectrum

Fixed Wireless Access (FWA) using CBRS band allows internet service providers to build out high-speed broadband networks quickly and cost-effectively. SAS combines licensed and general access CBRS spectrum effectively between base stations to Customer Premises Equipment (CPE) links, ensuring optimal data throughput for end users.

      Private networks

      CBRS spectrum for private 4G/5G cellular networks

      CBRS-based private 5G/LTE networks deliver improved coverage and security for business-critical applications not available with Wi-Fi. CBRS is also well suited for enterprises, public sector, and education customers who want to create local private cellular networks. SAS helps efficiently manage CBRS spectrum for private networks used by PAL and GAA users while avoiding interference.

          Mobile networks

          Building nationwide 5G networks for growth

          Mobile network operators can use CBRS spectrum to expand 5G network coverage across the country, complementing their existing 5G deployments in other bands. This allows them to accelerate their time to market for innovative mobility, broadband, and enterprise solutions. SAS coordinates the CBRS spectrum across GAA and PAL channels, ensuring that there is a high level of spectrum availability.
