Abstract
A wireless medium access control (MAC) protocol and system for implementing the MAC protocol is arranged to operate in such a manner as to avoid collisions from stations (STAs) comprising two or more IEEE 802.11 basic service sets (BSSs), collocated and operating in the same channel during contention free periods (CFPs). The MAC protocol utilizes ready-to-send (RTS)/clear-to-send(CTS) signals that are exchanged during CFPs to avoid potential collision from STAs in overlapping BSSs.
