802.11b Wireless Network Visualization and Radiowave Propagation Modeling

This paper outlines the methods of creating detailed coverage maps of 802.11b networks, with an emphasis on minimizing the expenses and time involved. The goal of this work is to develop and present a streamlined, reproducible approach to wireless visualization as well as techniques for predicting coverage area before conducting network installations. After evaluating these coverage maps, a repeated series of field measurements will be checked against interpolated values in order to improve techniques for extrapolation of data for unsampled regions. If successful, these extrapolation techniques will provide additional guidelines for, and assist modeling of, new wireless network installations. However, this paper demonstrates that due to the microcellular structure of indoor/outdoor 802.11b networks, accurate interpolation and propagation prediction techniques do not exist independent of highly specific location models. In lieu of the creation of extensive simulation environments, best practice guidelines for municipal wireless network planning and deployment are presented
