ESTIMATING WIRELESS CAPACITY

摘要

A system and method are disclosed that may provide an accurate estimate of an AP's available medium share. The AP may perform a plurality medium access contention operations to determine a duration of a transmit opportunity and a queue service interval for each of a plurality of access categories. The AP may also determine a queue service interval for a number of packet queues associated with each of the access categories. The AP may use timing information derived from the medium access contention operations to estimate a portion of the medium share available on a per-access category and/or per-user basis. The timing information may include the transmit opportunity durations and queue service intervals for the access categories, the queue service intervals for the individual packet queues, and/or values indicative of the AP's PHY rate and medium utilization.
