If there is no free channel on a beam forming the coverage including one given station, the method of the invention looks for free channels in each beam adjacent said beam, and allocates one of the adjacent beam free channels to the given station as soon as in an optimal subset of beams comprising all beams using the same channel as the free channel each level of isolation equal to the ratio of an antenna gain of a main lobe of a respective one of the beams of the optimal subset to the sum of the maximal antenna gains of secondary lobes of the other beams is greater than a given threshold. | |
