Abstract
In two superimposing communication systems using the same frequencies, where the second communication system was not considered in the frequency planning of the first cellular communication system, frequencies are to be allocated to the second communication system in a way that they do not interfere with the first communication system. Accordingly, a medium field strength of each frequency is calculated after a time interval has expired. A number of frequencies are selected in correspondence with the value of the medium field strength. A medium value is formed with the field strengths of the selected number of frequencies. The time interval of the calculation of the medium field strength of each frequency is changed in response to the medium value.
