Proposal to Administer a Environmental Sensing Capability
May 16, 2016

Key Bridge is pleased to submit our proposal to administer a Environmental Sensing Capability (ESC) in the 3.5 GHz frequency band to the U.S. FCC.

The Key Bridge ESC architecture is a comprehensive, end-to-end solution that completely satisfies all of the FCC's current requirements.

As in previous FCC initiatives Key Bridge has collaborated extensively to develop a body of industry standards and best practices to enable coexistence in 3.5 GHz. Key Bridge intends to offer commercial ESC services to our own and to other FCC-designated and certified SAS administrator on a non-discriminatory basis. ESC services will be offered through a technologically neutral, standardized peering service.
