Patent ID: 7801104

Claim:
A system in an IEEE 802.11 a wireless local area network, comprising: a counter for counting slot numbers; and a storage device to store data corresponding to a channel access scheme providing access to a wireless network, said access scheme using a modulo partitioning backoff scheme providing a modulo partitioning backoff, said channel access scheme further providing traffic prioritization, wherein each transmitter is allowed channel access after a backoff counter becomes zero and a current slot number t satisfies the modulo condition: t modulo N=n i where, t=a current slot number where a slot count begins at zero after short interface space (SIFS) interval past medium busy, N=total number of stations (STAs) in the wireless network, n i =a Unique ID assigned by the AP to each station (STA), and wherein SIFS is shorter than distributed coordinated function interframe space (DIFS) and arbitrary interframe space (AIFS).
