Abstract
Comparing market estimates for wireless personal communication and considering recent proposals for wideband multimedia services with the existing spectrum allocations for these types of systems show that spectrum resource management remains an important topic in the near and distant future. Future data traffic is not only expected to require a lot more bandwidth, it also is likely to be much more “bursty” and exhibit large variations in required throughputs and delay. Since today’s 2nd generation wireless communication systems are mainly geared to constant bit rate voice communication, the management of the spectrum resources in future systems poses a number of new and challenging problems. In this paper, first a few key problem areas in resource management are discussed. The main relative merits of two candidate principles, random channel allocation schemes, as found in frequency hopping or direct sequence CDMA systems, and deterministic dynamic channel allocation schemes are compared. The paper closes by giving some design examples derived from the European Community ACTS/FRAMES project.
