Method, computer program and system for characterizing radiofrequency environment

A computer implemented method for characterizing a radiofrequency environment, the method comprising:

• obtaining measurements of geometrical properties of physical objects in the radiofrequency environment, said geometrical properties including at least respective positions and dimensions of said physical objects,
• simulating radiofrequency ray-tracings involving a multiplicity of simulated rays, each ray being:
• emitted by a transmitter located in said radiofrequency environment in a transmitter position, and/or
• received by a receiver located in said radiofrequency environment in a receiver position,
• each pair of a transmitter position and a receiver position defining therebetween a radiofrequency path where simulated rays possibly interact with at least a part of said physical objects,
• selecting, among all the radiofrequency paths, at least one radiofrequency path,
• obtaining radiofrequency measurements of a radiofrequency channel defined by the selected path and estimating radiofrequency properties of physical objects interacting in said selected path,
• Said radiofrequency properties and said geometrical properties of said physical objects characterizing thereby said radiofrequency environment,
• wherein said selection comprises:
• assigning to the physical objects scores sk of interactions with the simulated rays, and
• selecting, among all the radiofrequency paths, at least one radiofrequency path defined by simulated rays interacting with the physical objects having the highest scores sk.
