Cognitive Radio and the Frequency Resource Protocol (FRP)

A distributed architecture for a commercial system for sharing the frequency spectrum is presented. This is obtained by running a new protocol called Frequency Resource Protocol. There are many challenges remaining, but none of these appear unrealistic to solve. Once a trial system has been demonstrated which is underway, the commercial incentives for launching this in terms of a realistic business model remains to be presented and will hopefully result in a standard used by many.
