Recently, the wireless connection has become a preferred technology, due to its ease in use and for its mobility, therefore , a rapid development has emerged in the wireless technologies. Wi-Fi is the most common technology used today. This paper discusses the Performance of Wi-Fi network in three cases: No fading, flat fading and dispersive fading by measuring the bit rate and packet error rate ratio (PER). IEEE 802.11a WLAN Physical Layer model is taken to simulate these three cases using Matlab simulation. I. Introduction: In the last years the mobility in computing and communications became more and more essential, especially for business usage. Mobility implies smaller sizes and more power considerations. It also, does not fit with fixed wired connections. The only suitable communication for mobile applications is wireless communication. The implication of mobility on computers appeared in the evolution of Notebook personal computers. On the other hand, the effect of mobility on computer networks appeared in the evolution of Wireless Computer Networks of which Wireless Local Area Networks are one kind. (1) Wi-Fi becomes the most common used wireless technology today. Wi-Fi was originally created to meet the requirements of relatively high bit rate and large bandwidth. Currently Wi-Fi is the primary wireless communication technology which is extensively utilized in the internet services because of its excellent capability and transparency to internet protocols. This paper describes the Performance of Wi-Fi network for three cases: No fading, flat fading and dispersive fading. The paper first gives a technical overview of the Wi-Fi wireless technology (IEEE 802.11). Then the paper Explain the methodology used and the model by using Matlab simulation Program. The paper then provides a comparative analysis of the three cases of fading and shows the results in tables and graphs. Lastly we conclude our paper.
