Abstract
Radio frequency reuse between two or more radio frequency communications systems is facilitated by having a beacon transmitter broadcast information globally throughout an area, which information identifies to users of a second system, which radio frequency resources are already in use by a first communications system. The global broadcast of information as to what channels are in use, permits users in the second system to avoid interfering use of those frequencies.
