Zusammenfassung:	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 the 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.
