Abstract
AP's associated with a communication network and any wireless devices desiring contact, operated according to a protocol in which each wireless device selects AP's with which to communicate. A system coordinator causes the AP's to operate so as to guide each wireless device to an AP selected by the system coordinator. This has the effect that, notwithstanding that the protocol involves having the wireless device make the selection of AP, functionally, the AP's make the selection for it. In a 1st technique, multiple AP's share an identifier, with the system coordinator directing one particular AP to respond to the wireless device, thus appearing to wireless devices as a “personal cell”. In a 2nd technique, AP's each maintain identifiers substantially unique to each wireless device, with the system coordinator directing only one particular AP to maintain any particular wireless device's identifier, thus appearing to wireless devices as a “personal AP”.
