Abstract:
1. A wireless transmission module, comprising: a first transceiver, which is used to broadcast and to receive wireless signals in a first frequency band; a second transceiver, which is used to broadcast and to receive wireless signals in a second frequency band; a switching circuit, which is used to provide a single path of transmission and to control switching between the first transceiver and the second transceiver; a processing unit, which is 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, and a cutting signal is generated to control the switching circuit to switch the path of transmission from the first transceiver to the second transceiver; and a signal detecting unit to detect the wireless signal in the first frequency band sent by the first transceiver and to notify the processing unit when the wireless signal in the first frequency band is detected to be smaller than a predetermined threshold.
