Abstract
The purpose of this invention is a method to provide a specific physical rate adapted to 802.11 WMM in EDCA mode which may be integrated as well in an Access Point as in a Station. The objective of this method is to select the 802.11 phyrate (physical rate) the most adapted for each WMM AC (Access category) of traffic requirements: For each AC it guaranties an IPLR (IP packet Lost ratio) specific physical rate and adapted to nature of the transported content. For BK (Background) and BE (Best Effort) it optimizes the used CUE (Channel Usage Estimation) in order to provide maximum bandwidth, For VI (Video) and VO (Voice) AC to guaranty first the delay bound (i.e. max IP Delay transmission (IPDT)) and when this condition is met it optimizes the used CUE.
