Key Bridge Wireless concludes CBRS ESC testing

Share Article

Key Bridge Wireless has successfully concluded testing of its Environmental SensingCapability system with the Institute for Telecommunication Sciences in support ofthe Citizens Broadband Radio Service.

Key Bridge Wireless is pleased to announce the conclusion of certification testing of its AI-enabled Environmental Sensing Capability. The Key Bridge ESC integrates cutting edge sensor technology, provided by Key Bridge partner Deepwave Digital, and is the first large scale commercial application of deep learning and artificial intelligence for spectrum monitoring and signal detection for telecommunication.

“Our ESC solution is a geographically distributed network of sensors that must perform flawlessly,” said Jesse Caulfield, CEO of Key Bridge Wireless. “Protecting incumbent users is the first and only priority for our ESC solution. We’ll wait for the official report to share details, but CBRS users who depend on our Environmental Sensing Capability can operate with complete confidence.”

“We have leveraged the latest methods in AI and deep learning to create a sensor that correctly identified every radar signal variant in the certification test suite with extremely high accuracy,” said John Ferguson, CEO of Deepwave Digital. ”Our detection algorithm was trained on tens of thousands of radar variants spanning the entire parameter space. We have coupled this software with our embedded, NVIDIA GPU-based, radio, the Artificial Intelligence Radio Transceiver (AIR-T). This allowed us to demonstrate that AI is a commercially viable solution to detect and discern current and future incumbent radar waveforms.”

The Key Bridge ESC network is currently being deployed and is expected to enter commercial service in early 2020.
