Abstract

The purpose of this study is to characterize the indoor chan nel for 802.11 wireless local area networks at 2.4 GHz frequency. This work presents a channel model based on measurements conducted in commonly found scenarios in buildings. These scenarios include closed corridor, open corridor, classroom, and computer lab. Path loss equations are determined using log-distance path loss model and log normal shadowing. The Chi-square test statistic values for each access point are calculated to prove that the observed fading is a normal distribution at 5% signi´Čücance level. A numerical analysis of measurements in each scenario was conducted and the study determined equations that describe path loss for each scenario.
