A protocol for inter-cell communication in a cognitive radio wireless access network using beacon period framing is disclosed. By establishing scheduled use of beacon periods within each frame of a super-frame among a plurality of participating cells in a wireless access network, efficient and reliable communication can take place eliminating beacon packet collisions and bandwidth wastage. Within each super-frame exits 16 data frames of fixed size which can each include both a data transmission portion and a beacon period. A protocol is established by which announcement, reserved, and free-to-use beacon periods are established within the super-frames associated with a particular spectrum. By coordinating communication between cells on the beacon period, collision between cells by simultaneous attempts to transmit or bandwidth wastage of periods in which no transmission takes place can be avoided.
