A wireless communication device includes an inner housing and a cover
detachably installed on the inner housing, the cover containing an ID
module for identifying the cover. A multi-band transceiver is disposed on
the inner housing for processing transmitted and received wireless
signals in one of a plurality of frequency bands. A detection circuit is
disposed on the inner housing for communicating with the ID module of the
cover and determining identification of the cover. The wireless
communication device also contains a memory electrically connected to the
multi-band transceiver and a database stored in the memory for providing
a frequency band identifier to the multi-band transceiver according to
the identification of the cover provided by the detection circuit for
changing the frequency band of the multi-band transceiver.
