Over-the-air (OTA) testing

What is OTA testing? Over-the-air (OTA) measurements are used to validate the performance of 4G/LTE & 5G antenna by looking at the radio-frequency (RF) and analyzing the spectrum. A quick check of the power parameters can validate the good health of a cell site. In certain case, RF interference mitigation can be required to improve OTA RF performance.
