The Wireless LAN includes multiple stations (STAs) (101-103), mobile or Stationary, airlinked (104) to an access point (105) as a Basic Service Set (BSS). A Hybrid Coordinator (HC) (117) is collocated with the access point (105) for allocating the bandwidth for the BSS to using a Controlled Contention/Resource Reservation Protocol defined in the IEEE Standard 802.11(e). The HC (117) transmits Contention Control (CC) frames and initiat es Controlled Contention Intervals (CCI) having a selected number of slotted intervals. HC (117) receives Resource Reservations (RR) detailing band width needs from STA contenders during a specified time interval called the Controlled Contention Interval (CCI).Several parameters are installed in eac h CC for contention control purpose. The several parameters are controlled to optimize efficient use of the wireless medium (104) and reduce access delays for RR frames contending for the wireless medium (104).
