Mobile WiMAX system level performance under different deployment strategies

For the WiMAX system networks, providing a high quality voice and data services, while at the same time mapping an ever increasing traffic demand on the radio propagation channel, is a challenging engineering task. There is an inherent trade-off between providing optimum quality of service and increasing capacity. This trade-off must be properly engineered to ensure that WIMAX networks deliver excellent service to their subscribers and increase profits by adding as many new subscribers as possible.;Since WiMAX is designed as a world-wide standard, the specifications allow for many different deployment options. The deployment options may use different frequency bands, paired or unpaired spectrum configurations, different channel bandwidths and a large set of advanced radio resource management options. As a side effect of numerous deployment options each particular network deployment needs to be preceded with a decision making process that helps select which deployment option is the optimum. This decision making process is multidimensional and practically very difficult without proper decision making tools. The goal of the work presented in this dissertation is development of decision making software that facilitates evaluation of different deployment scenarios. The software is effectively a system level simulator of the mobile WiMAX. It allows user to input a set of deployment parameters and through Monte Carlo type simulations it provides quantitative assessment of how effective particular deployment would be.;The design of the simulator, implementation of various WiMAX options and the simulator use in the decision making process are thoroughly described in the document.
