Efficient Spectrum Management for High Capacity Wireless Networks

The provision of Personal Communiactionm Services (PCS) is the goal of the evolution of integrated communication systems. The basic PCS philosophy is that the underlying telecommunication infrastructure will provide user-to-user, location independent, communication services. An indispensable feature of a personal communication network is that the final interface between the portable terminal and the network will be wireless, through radio base stations wired to the backbone network. In addition t o phone, a wide variety of services will be supported by PCS, including among others, video, pictures (picture-phone), paging and multimedia services. These services generate a large volume of communication traffic with diverse burstiness characteristics and quality of service requirements. The wireless network should be able to support this traffic and to meet the quality of service requirements. Efficient utilization of the limited radio spectrum will be vital for meeting the anticipated traffic demands of PCS.
