Does anyone have experience with the Huawei ASI4518R37 antenna? What would be the appropriate configuration for connecting a high-band radio (1800/2100) with 4 ports and wanting to achieve the best 4x4 MIMO performance? Does it make any difference whether you use y1-y4 or y2-y3, in terms of MIMO performance?
Not sure if it could be useful for you, but there is a CRS Antenna Port Mapping Optimization Detection function. After starting and complete the detection (could spend 10hours based on your cells number) you will get the Current & Optimal CRS Antenna Port Mapping… For me after alignment to the optimal I’ve got improvement on RSRP
