A wireless transmission module comprises: a first transceiver used to broadcast and to receive signals in a first frequency band; a second transceiver used to broadcast and to receive signals in a second frequency band; a switching circuit used to provide a single path of transmission and to control the its switches between the first transceiver and the second transceiver; and a processing unit used to control the switching circuit to switch the path of transmission from the first transceiver to the second transceiver when using the first frequency band of signal to communicate with a wireless device is not possible.
