What would happens if we install the wrong port between RRU_Antenna !

[bluep]

Dear bro
I know that the KPI and thoughput will low if we do the wrong port between RRU and antenna ( just like 1 to 2, 2 to 1 ...)
However, if with mimo 4x4, Port RRU 1 2 connect to port 3 4 of antenna , and vice versa, what would happens ?
And any document that show the details of this mismatch?
Tks a lot

"Downlink 4T4R network performance is affected by channel correlation, which is determined by the polarization and spacing between antennas"
so if you have wrong connections configuration, it will cause low channel correlation which led to low MIMO Rank2 % so Throughput will be low

Tks a lot , bro
So if installed with my first picture, the thoughput will be low, right ? Tks a lot
Do you have any document that recommend about it ?

Your CrsPortMap parameter setting must be matching with the actual connection configuration in field
as in below table
