This Statement is an incorrect description of a functional need, and may involve a lack of understanding of what "handoff" is. 802.11 has a need for Stations to transfer consecutive messages using different access points so a movable or moving Station always uses an adequate radio path for its communication. Meeting this need has nothing whatever to do with handoff.
