Patent ID: 7693527

Claim:
A method of wireless remote terminal communication within a restricted frequency band, the method comprising: geolocating, at the remote terminal, the remote terminal to generate a location specifier corresponding to a geographic location of the remote terminal; comparing said location specifier with remote terminal authorization information to determine authorization communication conditions for said remote terminal at said geographic location to communicate in the restricted frequency band, wherein said remote terminal authorization information comprises a geographic communication zone map, said geographic communication zone map containing information defining at least one geographic zone, wherein said at least one geographic zone comprises at least one intermediate zone, the step of comparing comprising: analyzing a position corresponding to said location specifier on said geographic communication zone map to determine in which geographic zone of said at least one geographic zone said geographic location corresponding to said location specifier is situated; and authorizing communications of said remote terminal in the restricted frequency band in accordance with said authorization communication conditions, wherein said authorization communication conditions are defined for each geographic zone, said authorization communication conditions corresponding to said at least one intermediate zone specifying that said remote terminal is authorized to communicate within said restricted frequency band for a period of time less than a re-authorization timeout period.
