Abstract:
1. A method for detecting a transmission device within a set area comprising: transmitting information to said transmission device, said information causing the transmission device to attempt connection to an available base station covering the set area; detecting a response transmission from said transmission device by a plurality of transmission detection facilities; extracting identification information associated with said transmission device contained in the response transmission sorting said response transmission received by the plurality of transmission detection facilities based on a characteristic of the transmission device; determining a location of the transmission device based on said sorted response transmissions received by said plurality of transmission detection facilities, wherein said plurality of transmission detection facilities are non-coplanar; determining an allowability of said located transmission device within said set area based on said identification information and said location; and preventing connection of the transmission device to the available base station when allowability is not indicated.
