The invention consists of an integration (IS) of a microwave system (MKT) with a millimetrewave system (MLBS) so that the total performance of the system is optimized. By combining the microwave system and the millimetrewave system it will be possible to very flexibly build an optimal infrastructure for different types of areas. Degree of coverage and range by that can be strongly improved where respective system is utilized for the task for which it is best suited.
