Abstract

Wireless communication technology is the basis of radio and television broadcasting, it is used in satellite-based cellular telephone systems, in point-to-multipoint radio access systems, and in terrestrial mobile cellular networks, to mention a few such systems (see [5] for more detailed information).

Wireless communication networks employ radio frequencies to establish communication links. The available radio spectrum is very limited. To meet today’s radio communication demand, this resource has to be administered and reused carefully in order to controlmutual interference. The reuse can be organized via separation in space, time, or frequency, for example. The problem, therefore, arises to distribute frequencies to links in a “reasonable manner”. This is the basic form of the frequency assignment problem. What “reasonable” means, how to quantify this measure of quality, which technical side constraints to consider cannot be answered in general. The exact specification of this task and its mathematical model depend heavily on the particular application considered.
