A method for planning a radiocommunications network includes computing
cell coverage in turn including dividing a region around a radio base
station into a number of large environment pixels, dividing each large
environment pixel into a number of small environment pixels, and, for
each target small environment pixel, computing a second quantity
indicative of the coverage within the target small environment pixel,
wherein each second quantity is computed for the respective target small
environment pixel as a function of a mixed environment profile describing
the environment between the radio base station and the target small
environment pixel along a propagation path of a radioelectric signal
radiating out from the radio base station and passing through the target
small environment pixel, wherein the mixed environment profile describes
the environment within small environment pixels close to the radio base
station and the target small environment pixel, and within large
environment pixels along the remaining stretch of the radioelectric
signal propagation path.
