Abstract:

The measurement and analysis of radio waves propagation play significant part in the plan and function of WLAN applications. This paper provides an overall coverage of the Wi-Fi in the indoor environment. In this paper radio waves propagation for indoor environments will be considered using the Wireless LAN 802.11b/g at the frequency of 2.4 GHz. This paper involves the study of the effect on building’s structure and materials used within the access points set up at different locations and obtaining Wi-Fi measurements and comparing them with values predicted by classical model such as ITU Indoor Propagation Model. Measurements of signal strength using the Wi-Fi card utility will be carried out in the research. The aim of this paper is to study the conduct of signal strength when it travels through line of sight (LoS) and non-line of sight (NLoS) and results will be compared with an Indoor site general model of ITU.
