ABSTRACT:
In a wireless local area network (WLAN), the present invention provides a system and method for identifying traffic suffering from bad link quality and dynamically adjusting channel access to restrict the effect of this bad link quality. The dynamic adjustment to channel access is accomplished by lowering or raising the limit on the number of packets that can be transmitted between an AP and the wireless station over the a link as determined by the link quality. The link quality is determined by tracking the number of successive packet transmission successes and errors.
