Characterization of Indoor Propagation Properties and Performance Evaluation for 2.4Ghz Band Wi-Fi

Abstract

Indoor wireless systems poses one of the biggest design challenges although it is the most flexible and easily deployable method of implementing Local Area Networks. This difficulty in predicting the propagation of radio frequency wave in indoor environments is caused by reflection, refraction, diffraction and scattering of signals due to closed proximities to furniture, walls, human beings, and reflectors like ceiling, mirrors and glasses. To help improve the user experience and guarantee good quality of service in indoor situations, the research investigated the throughput and attenuation effect on signal with respect to 4, 5, 6 and 9 inches sizes of blocks walls respectively. The characterized Path-loss exponent was 1.999 and differed from the free space model, Wall and Floor Factor model and ITU model by 53.54dB, 6.42dB and 6.85dB respectively.

QoS Analysis to Optimize the Indoor Network IEEE 802.11 at UNTELS

“…Many problems arise when implementing a network, greater is the case when it is a wireless network, this due to the hostile environment as gauging, temperature, distance and all kinds of natural barriers that faces the signal during the Transmitter/Receiver journey being impossible from the beginning to satisfy the QoS in its entirety and for all cases.
