Abstract:
1. Power planning method in a cellular wireless communication network (N) whose characteristic is to allow the reuse of one same frequency on all the cells of the network provided with radio base stations (BTS) having transmitters TR to transmit data to determined transmission sectors (Sc) and ensure radio coverage of areas defining respective cells, the method being implemented via a data processing system ( 1 ) provided with memorising means ( 11 ) storing data (d 1 ) representing geographical areas divided into a plurality of dots or pixels ( 301 , 302 , 303 ) depending upon the division of said network, data (d 2 ) characteristic of the sectors (Sc) and transmitters (TR) of the network, data (d 3 ) representing the transmit/receive radio attenuation for each sector (Sc), data (d 4 ) representing the traffic volume and distribution in the network, the method being characterized in that a computing module ( 10 ) of the data processing system ( 1 ), for each transmission sector (Sc) associated with a transmitter (TR) having a plurality of carriers (C 1 , C 2 , CN- 1 , CN), performs an assignment step ( 42 ) to assign carriers to service areas ( 2 ), the computing module ( 10 ) using the data (d 1 , d 2 , d 3 , d 4 ) stored in the memorising means ( 11 ) to distribute the total traffic (TF) to be handled in the sector (Sc) into N shares of traffic (TF/N) in N complementary services areas ( 2 ) determined in relation to their radio attenuation and geographically forming rings that are increasingly distant from the transmitter (TR), the method also comprising: an initialising step ( a list (d matrixes of propagation attenuation (d a matrix of traffic distribution (d a coefficient of use representing a traffic volume (d specifications (d matching rules (d estimation parameters (d a frequency planning step ( a power adjustment step (
