MIMO OTA is the well-established and predominant method to test mobile devices with multiple antennas. The MIMO OTA approach subjects the device under test to challenging channel conditions (Multipath, Doppler, Interference, Correlation, Cross-Polarization), and the mobile device is tested in a wholistic way, i.e. chipset, antenna design, and enclosure. Additionally, multiple antenna connectors make standard conductive tests complicated and impractical. As new 5G NR devices enter the market, it becomes necessary to create a test methodology that can assess their performance in a standardized way using a MIMO OTA test. |
