Google Cloud's Spectrum Access System is a cloud-based service that dynamically manages the Citizens Broadband Radio Service spectrum, facilitating efficient and interference-free wireless communication. By coordinating spectrum access among various users—including fixed wireless, mobile, and private network operators—SAS ensures optimal bandwidth utilization and maximized transmit power.
Key Features and Functionality:
- Reliability: SAS employs a distributed architecture designed to maintain uninterrupted communication between the system and CBRS devices, ensuring consistent service availability.
- EIRP Optimization: The system optimizes the Effective Isotropic Radiated Power for each CBRS device, enhancing network performance and user experience.
- Channel Guidance and Spectrum Planning: SAS provides tools for real-time and planned spectrum analysis, utilizing high-resolution geospatial data to estimate power and interference levels, thereby increasing available bandwidth and reducing interference.
- Environmental Sensing Capability Network: A robust ESC sensor network along U.S. coastlines detects incumbent federal use of the spectrum, allowing SAS to dynamically adjust allocations and minimize service interruptions.
- CBSD Performance Management Tools: A user-friendly, map-based portal enables easy spectrum availability checks, CBSD registration, and network status monitoring. Additionally, rich API communication logs can be analyzed in BigQuery for detailed troubleshooting and custom analytics.
