Shared Spectrum Administration

Shared Spectrum Access

White Space spectrum refers to wireless frequencies that are typically allocated or assigned to a licensed user but may also be used on a subordinate basis by unlicensed users on a non-interfering basis.

White space operation within the United States is currently authorized on frequencies historically reserved for broadcast Television service.

Most consumer electronics, such as WiFi devices, also operate on a non-interfering basis. You've probably read the disclaimer on a label: This device may not interfere with and must accept interference from other devices....

Key Bridge is an FCC-designated White Space administrator, and our White Space System enables spectrum sharing and co-existence between licensed and unlicensed users.
