Voice performance evaluation of BLUETOOTH system in the presence of IEEE80211b WLAN system

Abstract

This thesis uses the protocols of IEEE 802.15 (BLUETOOTH) and IEEE 802.11b (WLAN) to develop a BLUETOOTH radio system model on an OPNET platform. Typically, the wireless model is a simple model of BLUETOOTH technology implemented in C programming language, and assisted by the MATLAB programming language. In the environment, the WLAN, piconets, medical or microwave facilities may affect the performance of the BLUETOOTH system. In this thesis, IEEE 802.11b WLAN and piconets will be investigated and implemented as the interference sources in the simulation environment. The goal of the radio simulation is to explore the voice performance, under the limitations and restrictions of the current BLUETOOTH technology specifications. The performance is evaluated in terms of packet throughput, which is the packet loss rate of BLUETOOTH, and the quality of voice in terms of the MOS rating. This simulation will hopefully help the BLUETOOTH system designers and decision-makers in gaining insight into the system performance analysis and enable them to get a better solution for some designing issue.
