A system allowing reuse of one same frequency on all the cells of a network. It includes means storing data characteristic of the network and a computing module provided with means to associate carriers of a transmitter with service areas to distribute the traffic to be handled in the sector over N shares of traffic in N complementary areas determined in relation to their radio attenuation, and a determined frequency with each service area, the different carriers used being respectively associated with a single service area of a sector. With the system it is possible to adjust the transmission power of each carrier in relation to the determination made by the computing module to share the power of transmitter between the carriers of one same sector.
