An experimental study on the installation effect the EM wave absorber to wireless LAN communication environment

Indoor propagation by dipole antenna and throughput measurement by using commercial wireless LAN equipment are conducted for the experimental room, in order to investigate the effectiveness of setting EM-wave absorber for better wireless LAN communication environment. Comparison of well reflected environment, replacing of one side wall to the three layered absorber using common building material makes average delay profile half, and makes average throughput 40% faster. So, desired results of the better wireless LAN communication environment are confirmed by the installation of EM-wave absorber by this work. Simulation by ray tracing method is performed and the relationship of throughput to delay spread for the experimental room is also discussed in this paper.
