OTA testing of 5G's massive MIMO antenna arrays requires 3D perspective and high-performance equipment

摘要

Antenna arrays will play an essential role in future wireless communication. But challenges in their development, design and production make thorough testing essential to achieving optimal performance. The elimination of RF test ports and the use of frequencies in the centimetre and millimetre wavelength region make OTA a vital tool for characterising the performance of - not just massive MIMO arrays - but the internal transceivers as well. This will drive a high demand for OTA chambers and measurement equipment to measure the strict radiative properties of antennas and transceiver measurements. Rohde & Schwarz, with its wide range of anechoic chambers and measurement equipment expertise, is well situated to deliver solutions - even for future customer requirements.
