Abstract
The present invention is a novel method and apparatus for a dual-mode radio (DMR) in a wireless communication system. The present invention allows Bluetooth™ protocol and 802.11 protocol devices to co-exist. The present inventive method classifies Bluetooth™ protocol and 802.11 protocol events according to importance. In the basic dual-mode radio method, the present invention assigns two levels of importance or priority Bluetooth™ events: “high” and “low”. In the enhanced dual-mode radio method, the present invention assigns three levels of importance or priority to Bluetooth™ events: “high”, “low” and “promotable”. The present inventive apparatus provides a means for disabling 802.11 transmissions when high-priority Bluetooth™ events are detected.
