Abstract:
A wireless microphone and/or in-ear monitoring system having at least one first mobile device for wirelessly transmitting first audio signals. The system also has at least one base station for wirelessly receiving the first audio signals transmitted by the mobile device. The wireless transmission is based on an orthogonal frequency-division multiplexing transmission (OFDM) during a time-division multiple access (TDMA) time slot. Each wireless microphone occupies at least one slot within 2 ms. Each of the TDMA frames has a plurality of slots which respectively have precisely one OFDM symbol. Accordingly, precisely one OFDM symbol is transmitted in each TDMA slot. During a time slot made available in accordance with the TDMA, a transmission is effected on the basis of an OFDM method. The TDMA frame length is so short as a latency of <4 ms is required for professional audio transmission, for example in the case of wireless microphone systems.

Claim (Index 23):
A method of controlling a wireless microphone system that has at least a first mobile device, a second mobile device, and a base station, wherein the first and second mobile devices are mobile microphone devices, the method comprising:\n wirelessly transmitting first audio signals from the first mobile device via a first wireless uplink connection to the base station; wirelessly transmitting second audio signals from the second mobile device via a second wireless uplink connection to the base station; wherein the wireless transmission of the first audio signals and the second audio signals is based on an orthogonal frequency-division multiplex (\u201cOFDM\u201d) time-division multiple access (\u201cTDMA\u201d) transmission, wherein TDMA frames are used, and each of the first and second mobile devices transmits the respective audio signals at least once per TDMA frame; wherein each TDMA frame has a plurality of slots which respectively have one OFDM symbol; wherein at least one TDMA frame has a single beacon slot; wherein the base station is configured to transmit a beacon symbol in the beacon slot to the mobile devices; wherein each of the mobile devices is configured to utilize the beacon symbol for synchronizing their OFDM based transmission of the audio signals; and wherein said wireless transmission of the audio signals from the first mobile device and of the second audio signals from the second mobile device is synchronized based on said beacon symbol.
