To gain a better insight, note that for LTE, the conducted MU is set to +0.7 dB while the LTE OTA MU is already +2.6 dB. To add to these, because of the limited test equipment (TE) noise floor, the fact that a minimum of 10 dB SNR is required to obtain better than 0.4 dB accuracy, and the large path loss due to the distance separating the UE from the TE (e.g. 68 dB free space loss 1.5 m at 43 GHz), the dynamic range in OTA is limited. The impact on the conformance test is that a minimum transmit power has been agreed upon as - 13 dBm, while both the ACS test case 2 and the UE maximum input power require- ment of -25 dBm at the UE antenna port
