Transceiver and operation method thereof

A method of operating a transceiver, the method comprising:

• detecting a signal in a frequency band, which can be used by a first communication module and a second communication module, by a reception module having a low-power circuit;
• and
• establishing channels for the first communication module or the second communication module based on a strength of the signal detected by the reception module, by a controller.

A transceiver chip set, comprising a chip set configured to:

• detect a signal in a frequency band, which can be used by a first communication module and a second communication module, by a reception module having a low-power circuit;
• and
• establish channels for the first communication module or the second communication module based on a strength of the signal detected by the reception module, by a controller.
