Control of the power gains of reception and transmission within a wireless point to multipoint system.

Method for controlling power gain for use in a radio communication system including at least a master station able to communicate with at least one slave fixed station, acquiring and storing the parameters configuration master and relevant operation of the slave, monitoring the accesses of the slave and assigning physical resources, including the slave means for receiving and / or transmitting variable power gain, characterized in that includes the following steps: - the master station acquires a piece of information related to the distance between the station antenna slave and its own antenna; - the master station transmits to the slave station said piece of information; - the slave station receives said piece of information and translates it into at least one control signal semistatic gain keeping a fraction of said variable power gain configurable for compensating the free space attenuation of the radio path due only to said distance.
