Claim One:
1. A method for planning a radiocommunications network, comprising: computing, using a computer, cell coverage, to indicate a region around a radio base station where a radioelectric signal radiating out from the radio base station copes with given requirements; wherein computing the cell coverage comprises: dividing the region around said radio base station into a number of first areas; for each first area, computing a first quantity indicative of the cell coverage within the first area as a function of data describing an environment within the first areas along a propagation path of a radioelectric signal radiating out from said radio base station and passing through said first area; dividing at least some of said first areas into a number of second areas; and for at least some of said second areas, computing respective second quantities indicative of the cell coverage within said second areas, each second quantity being computed for a respective second area as a function of at least the first quantity computed for the first area containing said respective second area and of data describing the environment within said respective second area and within at least some further second areas within said first area and arranged upstream said respective second area along a radioelectric signal propagation path passing through said respective second area, wherein each second quantity is computed for the respective second area also as a function of the first quantities computed for first areas surrounding the first area containing said respective second area, and wherein in the computation of each second quantity for the respective second area, the first quantities computed for the first areas surrounding the first area containing said respective second area are each weighted by using a respective weight which is inversely proportional to a distance between said respective second area and the corresponding first area.
