A method of operating multiple virtual wireless networks using a common
distribution system. Multiple radio frequency side networks are attached
to multiple wired networks through a single access point. In this way
messages may be sent between a mobile unit and a local area network. The
mobile units and the local area networks are associated with identifiers
which are used to route a sent message. The messages are sent from a
mobile unit to a corresponding access point, which compares the
identifier of the mobile unit with stored identifiers in its memory and
assigns tags to the messages according to the intended local area
network. The tagged messages are then sent from the access point to the
distribution system that routes the message to the corresponding portal
and to the local area network.
