Abstract
A method of low latency group-addressed audio/video streaming in an IEEE 802.11 wireless network is provided. A data stream from at least one access point is transmitted to a plurality of wireless receiving stations as multicast traffic. The data stream comprises beacon frames at beacon intervals. Data packets of the data stream from the at least one access point are transmitted to a plurality of wireless receiving stations as multicast traffic as soon as available for transmission. The transmission of data packets that were transmitted during a previous beacon interval is repeated during a subsequent beacon interval as multicast traffic.
