Seamless roaming - options in an ieee 802.11 - compatible network

摘要

A communication protocol that provides load balancing and/or test pattern information between devices is described. A first embodiment of the protocol provides such information via a data frame that is transmitted a definitive time after a special DTIM beacon is transmitted. This protocol provides full compliance with IEEE 802.11. The second embodiment of the protocol modifies the 802.11 beacon data structure with additional information elements.
