The invention relates to a method and a device for measuring the antenna diversity gain in digital radio transmission systems, wherein the sensitivity of a receiver system is designed by using a plurality of antennas, wherein the signals thereof determine a diversity gain (DG) by means of the bit error rate (BER)-increase of the signals. The invention is characterized in that the method and the device for measuring the diversity-gain (DG) in digital radio transmission systems form an optimization of radio net planning by means of targeted use of diversity, wherein a decrease of the number of used base stations and an increase of the transmission- and receiving quality is achieved.

The invention relates to a method for allocating frequencies to base stations in a mobile telephone network, especially a method for automatically resetting frequencies already allocated in the case of non-saturated base stations and re-allocating frequencies to said base stations. Firstly, frequencies are allocated to base stations using any known prior art method. In the case where no non-saturated base station is present, a complete frequency plan is obtained. However, if some base stations are not saturated, the inventive method is carried out: the current frequency allocation is reset and a new frequency allocation is carried out automatically. A parameter, the resetting extent parameter, is used to determine to which extent the resetting method is implemented.
