A method is described of selecting, by a multi-antenna base station of a wireless communications system, at least one transmission beam to transmit data to at least one terminal. The method can include determining a grid of N2 transmission beams intended to cover a portion of the space served by the base station and generated by using N1 antennas of the base station, where N1 and N2 designate integers such as N2&#x3e;N1, and selecting one or more non-adjacent beam(s) of the grid to transmit data to at least one terminal during at least one given time interval.

An electric field emitted by an electronic equipment is measured by producing at least one radiation measurement in the radiating field of the equipment. Several sets of simultaneous near-field measurements, within a measuring surface located at a short distance from the equipment, are performed. The sets of performed measurements are processed by estimating the statistical properties of the radiated field at any point outside the measuring surface.
