Abstract: In a cellular communication system, particularly in a system using GHz frequencies, communication signals may become blocked by physical objects. As a result, communications may be disrupted or prevented. In a cellular system using beamforming and directional signal beams, a beam is tested prior to its use by sending a discovery signal over the beam, and by detecting any reflections of the discovery signal. A reflection may indicate the presence of a blocking object in the direction of the beam. By repeating this process using different directional beams, it is possible to produce a map of an area surrounding the base station, and to subsequently select or configure a directional beam for communicating with an individual user device. The process may also be used when selecting the antenna position and orientation for a new base station, by testing different alternatives and selecting an alternative that has relatively fewer blocking obstructions.
