Abstract Bluetooth is a suitable technology to support soft real‐time applications like multimedia streams at the personal area network level. In this paper, we analytically evaluate the worst‐case deadline failure probability of Bluetooth packets under co‐channel interference as a way to provide statistical guarantees when transmitting soft real‐time traffic using ACL links. We consider the interference from independent Bluetooth devices, as well as from other devices operating in the ISM band like 802.11b/g and Zigbee. Finally, we show as an example how to use our model to obtain some results for the transmission of a voice stream. Copyright © 2006 John Wiley & Sons, Ltd.
