Abstract: In this study, we present our findings of important IEEE 802.16d performance characteristics. This study is part of our ongoing study of wireless communications technologies for the Federal Railroad Administration and provides details about our approach to modelling various channel effects, such as Doppler shift and Rician fading, details of the effect of link quality conditions, expected throughput and distance characteristics, as well as the impact of multi-hop and multi-user scenarios. Based on our simulation model, we can find a maximum throughput of approximately 69 Mbits sec⁻¹ and a maximum distance of 31 miles, making IEEE 802.16d a promising candidate of addressing many critical requirements for large-scale deployments in environments such as the railroad industry. Our goal is to provide a comprehensive analysis that will assist others in understanding 802.16d performance and guiding future network deployments.
