Abstract—IEEE 802.16e fixed WiMAX provides a low cost solution for integrated multimedia access networks with a wide bandwidth making it particularly suitable for telemedicine applications. While a wide variety of modulation schemes are suitable for fixed wireless systems, single carrier modulations such as QAM offer advantages such as reduction in power requirements and system complexity compared to multi-carrier transmission systems. In this paper, we analyze the performance of QAM schemes used in a fixed WiMAX system that supports multicast distribution of .real-time traffic for healthcare services by evaluation of system performance on a 10 GHz carrier. Results are presented by comparing the distribution of video data using QPSK and 16-QAM and bandwidth utilization is calculated for continuous data transmission in remote patient monitoring.
