The ever-expanding and explosive growth of the Internet over the last decade has led to an increasing demand for high-speed, ubiquitous Internet access. Broadband Wireless technologies are increasingly gaining popularity by the successful global deployment of the Wireless Personal Area Networks (Bluetooth- IEEE 802.15.1), Wireless Local Area Networks (WiFi- IEEE 802.11b), and Wireless Metropolitan Area Networks (WiMAXIEEE 802.16a). In this paper we have used the MATLAB Simulator to analyze the performance of IEEE 802.15.1, and IEEE 802.15.4 . The performance metrics measured in this study includes BER (Bit Error Rate). The results show how BER(Bit Error Rate) affects the performance of IEEE 802.15.1 and IEEE 802.15.4.

Keywords : IEEE 802.11b, 802.15.1, 802.16a, Wi-Fi, Bluetooth, WiMAX, MANET, Matlab.
