Abstract: A method for estimating the electric field strength associated to a radio wave emitted by an electromagnetic source of a cellular radio communication network within an area. The method includes: identifying a set of obstacles; determining at least one of: a direct visibility polygon of points in line of sight with the source; a reflection visibility polygon of points reachable by the wave after reflection by the obstacles; a diffraction visibility polygon of points reachable by the wave after diffraction by the obstacles. The visibility polygons are associated to respective values of the electric field computed therein. The method further includes: subdividing the area into pixels; for each pixel, determining if it belongs to at least one of the visibility polygons; and in the affirmative, determining the electric field strength at the pixel as a value proportional to the electric field computed at the at least one visibility polygon.

Abstract: A method of planning deployment of a radio communication network in at least a portion of a geographic area is provided. The method comprises: providing a three-dimensional model of the at least a portion of the geographic area; providing a model of at least one radio base station, the model comprising at least an indication of a position of the radio base station within the geographic area; and evaluating a propagation channel within the at least a portion of the geographic area associated with electromagnetic radiation, radiated by the at least one radio base station, at predetermined positions in the three-dimensional model of the geographic area. The method further comprises planning the deployment of the radio communication network based on the evaluation of the propagation channel.
