ABSTRACT:
A wireless telecommunications terminal employing both an IEEE 802.11 radio and a Bluetooth radio is disclosed. The illustrative embodiment employs a novel preemption scheme that ensures that Bluetooth preemptions of the 802.11 radio are not fatal to the 802.11 media access control (MAC) error-correction mechanism. The illustrative embodiment thus enables what appears to be concurrent 802.11 and Bluetooth activity by a single wireless telecommunications terminal. The preemption scheme does not require any changes to the 802.11 and Bluetooth protocols, or to the radios. It will be clear to those skilled in the art how to make and use alternative embodiments of the present invention for protocols other than IEEE 802.11 and Bluetooth that might interfere with each other.
