摘要： A radio communication system comprises a plurality of Bluetooth radio devices (Ia, Ib5 Ic, Id). Each device has a microphone (5), an audio output, such as a loudspeaker (7), and a short range radio transceiver (2a, 2b) capable of communicating digital data with a plurality of compatible neighbouring radio devices. Each radio device is configured to receive outgoing audio data from a first neighbouring radio device, to mix an input audio signal received at the microphone (5) with the received outgoing audio data and to transmit the combined audio data to a second neighbouring radio device. Each radio device is further configured to receive incoming audio data from the second radio device, to output an output audio signal corresponding to the received incoming audio data to the audio output and to re-transmit the received incoming audio data to the first radio device. The radio devices form a communication chain and each radio device is in communication with a maximum of one first radio device and one second radio device. A start radio device Ia which has no first neighbouring radio device is configured to transmit to the second radio device audio data corresponding to only the input audio signal. An end radio device Id which has no second neighbouring radio device is configured to re-transmit the combined audio data to the first radio device. The system provides an audio network that can include a large number of participant devices.
