Abstract: A multi-objective wireless local area network (WLAN) design models have been developed to optimize the network quality of services. The proposed model combines three problems together, including the optimal access point placement, the frequency channel assignment and the power level assignment. In addition, it accounts for user population density in the service area, traffic demand characteristics and the physical structure of the service area. The design model aims to determine a network configuration that optimizes the network quality of services in term of the radio signal coverage and the data rate capacity to serve expected user traffic demand in the service area. Numerical results and sensitivity analysis is performed to analyze the improvement of the network performance. We found that when we incorporate the issue of the user data rate capacity in the design model, we can greatly improve the quality of service in term of data rate requirement while slightly !
degrading the signal coverage availability. It is observed that as the weight factor of the user data rate capacity objective increases from 0 to 1, the user satisfaction level increases about 40% while the signal coverage availability decreases about 10%.
