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.

In some cases the station can switch between enabling and disabling the non-zero backoff procedure during different periods of time.
