Abstract

The present disclosure provides a wireless peripheral device with multi-transmission capability. The wireless peripheral device wirelessly transmits a control signal to a wireless receiver. The wireless peripheral device comprises a first wireless transmitting unit, a second transmitting unit, and a processing unit. The second transmitting unit receives a responding signal from the wireless receiver. The capable transmission distance of the first transmitting unit is larger than the capable transmission distance of the second transmitting unit. The processing unit is coupled to the first transmitting unit and the second transmitting unit. The processing unit transmits the control signal through the second transmitting unit to the wireless receiver when the strength of the responding signal is at a high intensity range. The processing unit transmits the control signal through the first transmitting unit to the wireless receiver when the strength of the responding signal is at a low intensity range.
