LAN based wireless communications system
A method of routing calls from a mobile unit to a destination location can include registering the mobile unit with a wireless adjunct, wherein the wireless adjunct is in communication with a switching unit and a packet based network and is operable to receive data from the switching unit and place the data, in packetized form, on the packet based network. The method can further include responding to a call setup request from the mobile unit and querying a subscriber database to determine if the mobile unit is a resident or a guest. If the mobile unit is a resident, communications data can be routed from the mobile unit through the switching unit to a first destination location. If the mobile unit is a guest, communications data can be routed from the mobile unit through an RF source to a second destination location.
