Increasing the volume of test zones in anechoic chamber MIMO Over-the-Air test set-ups

The essence of Over-the-Air testing is the emulation of realistic radio environments, in order to assess the communication performance of devices under test with their antennas in interaction with the environment, especially with the advent of MIMO. To this end, the communication signals are to be convolved with the spatio-temporal characteristics of the mobile radio channel before they are received by the test object.
