Optimal design of wireless local area networks (WLANs) using simulation

In this paper, we introduce a wireless LAN design framework for optimal placement of access points (APs) based on detailed coverage area and capacity requirements in the operational environment. The framework provides a combination of optimization algorithms that place APs for maximizing coverage and capacity, while minimizing interference and deployment cost. The framework accurately models RF propagation effects and leverages OPNET Modeler^娫s discrete event simulation (DES) capabilities to validate the output of the optimization algorithm. The algorithm can be executed iteratively incorporating recommendations from DES results to provide verifiable and optimal AP placement.
