Abstract :
The 2360-2400 MHz frequency band has been proposed for the medical use of body sensor networks. This paper investigates the performance of IEEE 802.15.4 and its high rate extensions (to 500 kbps and 2 Mbps) in this new band. Two receiver structures, namely correlation and hard decision receivers are evaluated based on a number of performance metrics including BER, spectrum efficiency, throughput, and interference. The results show that the IEEE 802.15.4, with lowered transmit power, is suitable for most medical body sensor network applications, though higher rate extensions are necessary for some particular applications.
