During the past decade, a major development in the telecommunications industry has been the explosive growth of the cellular telephone market. There are currently over two billion subscribers world-wide. In the US alone, the cellular service industry generates an annual revenue in excess of one hundred billion dollars. Even though the demand for cellular phone service shows no sign of slowing down, the industry is preparing for the next wave of innovation which includes wireless services such as high-speed data, audio/video streaming for web conferences, news, lectures, music, movies, etc. These different applications require inherently different Quality of Service (QoS) levels. The challenge is to design systems capable of supporting applications which are both appealing and affordable.Beyond the cellular network, there is a whole range of emerging wireless communication technologies. Ultrawide bandwidth technology is being proposed for very high speed data transfers over short distances. New generation wireless local area networks are being designed to support higher bit rates while offering improved security. Standards are being adopted for wireless metropolitan area networks which will establish wireless local loops to the home. Mobile ad-hoc and sensor networks are emerging as potentially important for specific applications.This research program will investigate a number of issues related to the design and performance analysis of multimedia wireless communication systems. It will train highly qualified personnel in the telecommunications field, one in which Canada has historically made significant research contributions. The results from this research will assist in the development of innovative communication services to the consumer at an affordable cost.
