Patent ID: 8264540

Claim:
A bidirectional wireless transmission and communication system, comprising: a base station comprising a base-station wireless transceiver module; and a wireless microphone comprising: a wireless transceiver module performing a bidirectional wireless communication with the base-station wireless transceiver module; a voice processing module receiving a first sound signal around the wireless microphone or outputting a second sound signal transmitted from the base station; a storage device storing the first sound signal or the second sound signal; and a microcontroller being connected to the wireless transceiver module, the voice processing module, and the storage device, and converting the first sound signal into a first RF signal for wirelessly transmitting to the base station; wherein when the bidirectional wireless communication between the base station and the wireless microphone is performed, the base station creates a base-station backup data stored in a database connected to the base station, and the wireless microphone creates a wireless microphone backup data stored in the storage device, and the base-station backup data and the wireless microphone backup data records the first sound signal and the second sound signal at the same time; and wherein when the bidirectional wireless communication is interrupted for a period of time and resumes later, the wireless microphone immediately transmits contents of the wireless microphone backup data within the interrupted period of time to the base station to complete the base-station backup data.
