Abstract
A wireless communication system, in particular a wireless LAN includes at least two mobile units, one of the mobile units including an adapter card configured to support embedded access point capability and including an association table for retaining status information concerning other mobile units in the network and message transmit queues allowing the system to operate in power saving polling mode. According to another aspect the invention relates to a wireless communication system including roaming mobile units wherein, when a mobile unit roams from a first access point to a second access point, the first access point only becomes aware of the roam once the mobile unit has transmitted a packet on to the backbone.
