Abstract: 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, for each large environment pixel, computing a first quantity indicative of the coverage within the large environment pixel, dividing each large environment pixel into a number of small environment pixels, and, for each small environment pixel, computing a second quantity indicative of the coverage within the small environment pixel, wherein each second quantity is computed for the respective small environment pixel as a function of the first quantity computed for the large environment pixel containing the small environment pixel, and of data describing the environment within the small environment pixel and within small environment pixels within the large environment pixel and arranged upstream the small environment pixel along a radioelectric signal propagation path passing through the small environment pixel.

Abstract: The radiation characteristics of an antenna are made configurable including in the antenna a plurality of radiating elements and associating to each of said radiating elements a respective chain for processing the signal in transmission and/or reception with a module for weighting digital signals capable of applying to a digital signal at least a respective weighting coefficient and an antenna conversion set interposed between the module for weighting digital signals and one of the radiating elements of the antenna. The antenna conversion set operates on a digital signal on the side of the signal weighting module and on an analogue signal distributed on the processing chains associated to each radiating element of the antenna propagates (in transmission and/or reception), while respective weight coefficients are applied to said digital signal weighting modules. The weighting coefficients determine the radiation diagram of the antenna.
