Contention-based protocol
A contention-based protocol (CBP) is a communications protocol for operating wireless telecommunication equipment that allows many users to use the same radio channel without pre-coordination. The "listen before talk" operating procedure in IEEE 802.11 is the most well known contention-based protocol. Section 90.7 of Part 90 of the United States Federal Communications Commission rules define CBP as: This definition was added as part of the Rules for Wireless Broadband Services in the 3650-3700 MHz Band.
