"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""."
