Title:
Study on the Performance of Wireless Local Area Network in a Multistory
Environment with CDMA Techniques
Abstract: A Wireless Local Area Network (WLAN) is a flexible
data communication system implemented as an extension to, or as an alternative
for, a wired LAN with in a building or campus. However, communications in
an indoor environment present problems not encountered in outdoor wireless
communication systems. Since cellular type systems are interference
limited, the indoor environment is more hostile than the outdoor environment
due to the lower propagation constant. In this paper, the equation
for the signal to interference ratio in a multistory building will be derived.
Finally, the simulation in this research is designed to study the Bit-Error-Rate
(BER) of WLAN system in the multistory environment by applying the some CDMA
modulation techniques. The procedure allows a quick evaluation of BER level
in Wireless LAN system due to the co-channel interference in the multistory
environment.
