Deployment and Study of Voip-Over-Wlan Based Intracom on UG Campus

Abstract

Communication between people over a distance has evolved over the centuries from smoke signals, drum beating era to telephony and the current era of mobile wireless communication. The evolution of Internet Protocol has encouraged the introduction of VOIP systems on a converged data network and has indicated many benefits of the VOIP systems on a converged data network even though there are challenges as well. A test bed of VOIP-Over-WLAN was built at the Department of Computer Science of University of Ghana, Legon. The wireless environment of the location was surveyed to read values of Radio Frequency parameters that measure the performance of a resilient wireless network and quality of voice transmitted. The study has shown that the inherent challenges of the wireless LAN could be monitored and managed with wireless survey tools. Good results were obtained for the quality of voice transmitted at the various of the location. This is an indication that the VOIP system was properly designed and the wireless environment is ready for such a system.
