Abstract
Wireless Access Networks offer an alternative method for connecting subscribers to the global telecommunication networks. They will become widespread only if they can provide an attractive set of communication services at competitive prices and quality. Fundamental to achieving these goals is how the scarce radio frequency is managed. We evaluate a few alternative resource management principles and highlight some key design issues for such networks. The emphasis is on providing services that require certain minimum performance guarantees in order to be useful. High quality communication services and efficient resource management is only possible if the resource requirements of different services can be adequately described. We propose a framework for expressing wireless communication services in terms upon which radio resource management algorithms can operate. A price/priority component can be used to prioritize between different services. A comparison is made between fixed (FCA) and dynamic (DCA) channel allocation for multi-service TDMA networks. We show that if access networks should be capable of offering high peak-rate services, i.e., requiring more than a few percent of the available frequency spectrum, dynamic channel allocation techniques seem an imperative design component.
