Abstract
For the effective implementation of a wireless local area network (WLAN) within a
building, a complete understanding of indoor signal propagation is required. This
paper compares three empirical propagation prediction models with regards to
efficiency and accuracy. To achieve this, a software prediction tool was developed
using C++ which allows an end user to quickly draw a building floor plan using user
specified drawing materials. It also has the ability to calculate the required empirical
parameters from entered measurements but this was found to produce results similar
to that when theoretical empirical parameters were used. The accuracy of the
prediction tool was gauged by comparing its outputs, using the different empirical
models, to measurements. In doing so it was determined that two of the models
produced functional levels of accuracy in which 93% and 82% of the simulated
results were within 15 and 10 dB of the measured results respectively for the most
accurate of the models used. All three empirical models were found to have
computational times low enough, less than 5 minutes for an average building, as to
allow for interactive WLAN design.
