Protocol to Access White-Space (PAWS) Databases
RFC 7545

Received changes through RFC Editor sync (changed abstract to 'Portions of the radio spectrum that are allocated to licensees are available for non-interfering use. This available spectrum is called "white space". Allowing secondary users access to available spectrum "unlocks" existing spectrum to maximize its utilization and to provide opportunities for innovation, resulting in greater overall spectrum utilization.

One approach to managing spectrum sharing uses databases to report spectrum availability to devices. To achieve interoperability among multiple devices and databases, a standardized protocol must be defined and implemented. This document defines such a protocol, the "Protocol to Access White-Space (PAWS) Databases".')
