Abstract
In a wireless local area network, a first and second access point in which the RF coverage areas overlap are synchronized by positioning a monitor station within the overlap area. The monitor station receives beacon frames from both access points and records the arrival times. A manager in communication with both access points and the monitor station calculates a retardation interval and issues a control command to the second access point to retard transmission of its beacon frame. The retardation interval is calculated such that the contention-free period of the second access point does not overlap the contention-free period of the first access point. The manager may also issue control commands to the first and second access points to adjust their contention-free periods.
