摘要

The transceiver has a learning module (123) that learns frequency bands or exchanged protocols utilized by a radio module (11). A geographical zone identification unit (125) comprises a locating unit (121), e.g. GPS, to locate the geographical zone and place of usage. A microprocessor (12) comprises a control unit (122) for controlling frequency band utilized by the radio module according to identified zone.
