To meet the ever increasing need for wireless communication bandwidth, the proposed 5G new radio access technology will utilize techniques such as beamforming and massive MIMO which have not seen widespread adoption in any previous wireless technology. It will also attempt to use millimeter wave frequencies for mobile communication at a scale never seen in previous defense and satellite applications. These decisions will have a drastic impact on the test methods used to validate the operation and performance of new radio designs, requiring radiated test techniques to replace tests that are traditionally performed. This paper will touch on various issues the industry must address, and the current work in 3GPP to develop the basis for these test techniques before the radio design has even been completed.
