Abstract
A method and apparatus for automatically adapting a mobile unit to the communications requirements of a particular country or geographic region is provided. A wireless data communication network located in a particular country or geographic region includes one or more access points for communicating with the mobile unit. The mobile unit receives from an access point an announcement message broadcast. The message has a unique frequency characteristic associated with the geographic location of the access point from which it was broadcast. The mobile unit then determines an allowable frequency set for use in the country or geographic location associated with the access point. The mobile unit adjusts its frequency set to operate o the allowable frequency set. The mobile unit may also adjust others of its operating parameters in a similar fashion.
