1. A method for mobile communications, comprising:
- linking together a network of wireless local area network (WLAN) access points at respective physical locations;
assigning to the access points respective logical identities defining channels for use by mobile stations in a vicinity of the network in communicating over the air with the access points; and
altering the logical identities assigned to one or more of the access points by conveying a signal over the network.

Abstract
Apparatus for mobile communications includes a plurality of wireless local area network (WLAN) access points at respective physical locations, linked together in a network. The access points have respective logical identities assigned thereto, the logical identities defining channels for use by mobile stations in a vicinity of the network in communicating over the air with the access points. A control unit is coupled to convey signals over the network so as to alter the logical identities assigned to one or more of the access points.

37. Apparatus for mobile communications, comprising:
-
a plurality of wireless local area network (WLAN) access points at respective physical locations, linked together in a network, each of the access points comprising;
a baseband processing module for generating modulated baseband signals, the baseband processing module having a respective logical identity programmably assigned thereto, the logical identity defining a pattern of modulation of the baseband signals for use in communicating with mobile stations in a vicinity of the network; and
a radio module, coupled to the baseband processing module and adapted to convert the baseband signals to radio frequency (RF) signals for transmission over the air to the mobile stations; and
a control unit, which is coupled to convey signals over the network so as to reprogram the logical identity of the baseband processing module, thereby changing the pattern of modulation.
