BIDIRECTIONAL WIRELESS TRANSMISSION AND COMMUNICATION SYSTEM

摘要

A bidirectional wireless transmission and communication system is disclosed, including a base station, a wireless microphone and an external control device. A bidirectional wireless transmission and communication may be performed between the wireless microphone and the base station. The external control device is connected to the wireless microphone wirelessly or via a cable for controlling the wireless microphone via at least one push button on the external control device. The external control device is also provided with at least one light-emitting element to show the function operating state of the wireless microphone. The wireless microphone is internally provided with a global positioning system and a G-sensor for locating the coordinates of the wireless microphone under different situations. When the wireless microphone is located beyond the wireless communication range, the wireless microphone emits a high-power pulsed radio frequency signal for the base station to locate the position of the wireless microphone.
