I’m looking for guidance for pointing directional antennas used with the RM520N-GL. There is apparently no direct correlation between the antenna ports (ANT0-3) and AT commands that output RSRP (PRX, DRX, RX2, RX3). AT+QRSRP seems to report only actively used MIMO links. When using directional 4x4 MIMO antennas, I can turn one of the antennas in the wrong direction and almost nothing changes on the RSRP reading. Are there any tips for antenna pointing using AT commands?
Actually, when you tested this in real network, it has little impact, so you didn’t see any obvious change. It is recommanded to test it in the lab, like test UXM OTA.
