With 0.5 dB STD repeatability differences across CATR systems in two different continents, EMITE has found that current commercial 5G devices exhibit RF OTA performance differences above 5 dB. The ability to independently test 5G device performance to meet market demands and enhance first generation 5G devices becomes of the outmost importance, and EMITE-unique signaling-box-independent CATR Test Platform for simultaneous FR1 and FR2 OTA testing represents the state of the art equipment for achieving an ever-increasing demand of high performance 5G devices.
