A wireless communication system includes a first access point, and at least one first station in communication with the first access point. The first access point controls access parameters for communications with a first station. The access parameters may include Enhanced Distributed Channel Access parameters such as a minimum or maximum contention window parameter, an arbitration interframe spacing parameter, or a transmit opportunity limit parameter. The access parameters also may include a channel bandwidth parameter, a transmit power parameter, or a data rate parameter such as a modulation and coding scheme parameter. Where the system includes an additional access point, and at least one additional station in communication with the additional access point, the first access point and the additional access point control access parameters to avoid interference between the first access point and the additional access point. A central controller may coordinate between the first and additional access points.
