When radio waves are sent to an antenna, they are spherical in the near field but becomes a plane wave in the far field. RanLOS has developed an innovative and portable solution to convert near field waves to far field waves at a distance of only a few meters. RanLOS products consists of an antenna array with a series of antennas that send signals to a reflector and when the waves bounce off the reflector, they are converted into plane waves.

An example from a real environment is when a base station sends a signal to a vehicle on a country road, then a plane wave directly hits the antenna of the vehicle at a random angle. To test this in a controlled test environment, direct plane signals are sent at different angles to the communication system of the vehicle. The entire process is controlled by RanLOS’ measurement software, which performs a measurement in five simple steps. The results are presented in easy graphical layout and can be exported to be used as input data for simulations for autonomous vehicles for example.
