Abstract: A method and apparatus for audio stream sharing via a wireless link between an audio source device having an RF transceiver and audio sink devices each having an RF transceiver and a body area network (BAN) transceiver is described. Audio data is wirelessly streamed between an audio source device and an audio sink device via the respective RF transceiver. A user contact is detected on one of the audio sink device and a further audio sink device resulting in a BAN connection between the respective BAN transceivers of the audio sink device and the further audio sink device. In response to determining the user contact, a wireless link is setup between the audio source device and the further audio sink device. Audio data is then wirelessly streamed between the audio source and the further audio sink device via the respective RF transceivers.

Abstract: One example discloses a wireless device, comprising: an input configured to receive an interference signal; a transmitter configured to generate a transmit signal having either a first data rate or a second data rate; and a controller coupled to the input and the transmitter, and configured to define an interference threshold; wherein the controller is configured to command the transmitter to modulate the transmit signal at the first data rate if the interference signal is below the interference threshold, and modulate the transmit signal at the second data rate if the interference signal is above the interference threshold.
