Abstract
In a wireless local area network, a method and apparatus for providing a multicast address data packet from a single access point to one or more mobile units coupled to the access point is disclosed. A data frame packet is formed containing two or more data packets, each packet targeted for different mobile units having unique unicast addresses. The data frame is transmitted to the mobile units and each of the mobile units derives the proper data intended for it from the data packets, by examining the unicast addresses of each packet.
