Interference in the 2.4 GHz ISM Band: Impact on the Bluetooth Access control Performance
Nada T. Golmie, F Mouveaux
The emergence of Bluetooth devices operating in the same 2.4 GHz ISM frequency band as existing Wireless Local Area Network devices implementing the IEEE 802.11 standard specifications may lead to signal interference and result in significant performance degradation of both systems. In this paper, we attempt to quantify the performance of Bluetooth devices operating in the same environment as WLAN devices. We derive a probability of packet collision at the Bluetooth receiver based on frequency and packet frequency overlap time and use it to give preliminary results on the impact of interference on Bluetooth systems. Performance is measured in terms of packet loss and access delay for voice and data traffic. We show the effect of FEC on the results for different symbol error rates.
