Abstract: The present invention provides a wireless communication circuitry including a processor, a communication path and a channel detection path. The communication path is configured to wirelessly communicate with an electronic device by using a first channel. The channel detection path is configured to detect at least one channel different from the first channel to generate a detection result while the communication path is wirelessly communicating with the electronic device by using the first channel. The processor determines a second channel based on the detection result, and the processor controls the communication path to switch to the second channel from the first channel to communicate with the electronic device.

Abstract: A wireless communications includes a first wireless communications and a second wireless communications. The first wireless communications module transmits or receives a first wireless signal in a first frequency band selected from a first frequency range. The second wireless communications module transmits or receives a second wireless signal in a second frequency band selected from a second frequency range, and adjusts a transmission power of the second wireless signal in response to that a frequency offset between the first frequency band and the second frequency band falls within a predetermined range. The first wireless communications module is further configured to determine an in-band range in the overlapping part of the first and second frequency ranges, and a transmission power of the second wireless signal is adjusted in response to a frequency offset between the first frequency band and the second frequency band.

Abstract: The present invention provides a control method of an electronic device is disclosed, wherein the electronic device includes a first antenna and a second antenna. The control method includes the steps of: setting one of the first antenna and the second antenna as a default antenna; receiving a plurality of packets within an interval; for each of the plurality of packets, comparing a signal strength corresponding to the first antenna and a signal strength of the second antenna to generate a first comparison result; updating a first value or a second value according to the first comparison result; wcomparing the first value and the second value to generate a second comparison result when running out the interval; and selecting one of the first antenna and the second antenna to be the default antenna according to the second comparison result.
