Abstract: An access point in a random access wireless network is presented, which performs medium access control for transmissions from a plurality of stations to the access point using a carrier sense multiple access protocol. The CSMA protocol is based on the access point having a variable sensitivity level to detecting other transmissions on a wireless channel in order to avoid data collisions. In a dense network environment, the sensitivity level can be reduced to avoid detecting transmissions to other access points, and thus improve area efficiency.
