A Measurement Study of Speex VoIP and H.264/AVC Video Over IEEE 802.16d and IEEE 802.11g

Despite the significant interest in WiMAX technology and deployment (see www.wimaxforum.org); WiMAX equipment is yet to become readily available at affordable prices. In fact, there is lack of publicly reported measurements from testbeds and field trials. As such, most WiMAX studies employ simulation and modeling. This paper takes a different approach and reports testbed measurements, in an attempt to understand what is realistically possible using off-the-shelf fixed WiMAX equipment. In particular, the authors present results from a measurement study involving both video and voice over a fixed WiMAX testbed.
