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 1):
A wireless audio transmission system comprising:\n at least two mobile devices configured to:\n wirelessly transmit first audio signals; \n wirelessly receive second audio signals; or \n wirelessly transmit first audio signals and wirelessly receive second audio signals; \n wherein different mobile devices transmit different first audio signals and/or may receive different second audio signals; and \n at least one base station configured to:\n wirelessly receive the first audio signals transmitted by at least a first mobile device of the at least two mobile devices; \n wirelessly transmit the second audio signals to at least a second mobile device of the at least two mobile devices; or \n wirelessly receive the first audio signals transmitted by at least one of the at least two mobile devices and wirelessly transmit the second audio signals to the at least one of the at least two mobile devices; \n wherein the wireless transmission of the first audio signals, the second audio signals, or both 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 at least two mobile devices:\n transmits the first audio signals at least once per TDMA frame; \n receives the second audio signals at least once per TDMA frame; or \n transmits the first audio signals and receives the second audio signals at least once per TDMA frame; \n 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 at least one base station is configured to transmit a beacon symbol in the beacon slot to the at least two mobile devices; wherein each of the at least two mobile devices is configured to utilize the beacon symbol as comparison information for the OFDM based transmission; and wherein said OFDM based transmission of the first audio signals from the first mobile device and said OFDM based transmission of the second audio signals to the second mobile device is based on said beacon symbol.
