WIRELESS FLEXIBLE PERSONALIZED COMMUNICATIONS	COST 259
Sub-Working Groups

The goal of this subgroup is to set up a collection of frequency planning scenarios. These scenarios will be used to evaluate the quality of various frequency planning algorithms and to stimulate the development of new algorithms for complex planning problems. Common file formats for the presentation of scenarios are highly desirable for an easy exchange of scenarios and frequency plans and will be established in the initial phase.

In the beginning, the focus of the subgroup will be on fixed (or static) channel assignment problems in GSM networks. In the course of the action, the scope will be enlarged to contain more complex scenarios like dynamic channel assignment, hybrid networks with static and dynamic parts, and networks with a mixture of macro and micro cells. The collection of scenarios will serve as a benchmark for frequency planning algorithms. The expected results of the bench-marking process are:

- the assessment of the quality of the assignments produced by frequency assignment algorithms, and
- insights to which extend a future increase in traffic can be handled by the use of sophisticated techniques for freqeuncy planning while keeping the use of radio frequency resources fixed.
