Abstract: A wireless local area network (WLAN) protocol having a non-zero backoff procedure which is bounded by setting a backoff counter to a random value greater than or equal to at least one backoff slot in starting to contend for a channel. This is preferably utilized in combination with setting the Arbitration Inter-Frame Spacing (AIFS) time to an amount less than that utilized for a legacy backoff. The parameters controlling the non-zero backoff may be set by the station performing the contention, or by an associated Access Point (AP), or in response to negotiation between the station and the AP. In some cases the station can switch between enabling and disabling the non-zero backoff procedure during different periods of time.
