Viewing MMI and XPI Levels (CLI)
You can view MMI and XPI levels for the individual radio carriers in a MIMO group.
Note that the MMI value can also be calculated manually. To calculate it manually, you must
measure the following RSL levels per receiver:
1.
Mute all remote transmitters except the transmitter for the link you want to measure, and
measure the local RSL level (RSL_Wanted).
2.
Mute all remote transmitters except the same polarization interferer and measure the local
RSL2 (RSL_Int).
3.
The MMI is equal to RSL_Wanted – RSL_Int.
To show the status of a MIMO group, as well as the MMI and XPI levels for the individual radio
carriers, enter the following command:
root
> radio mimo show status group 1
The following is a sample output from this command:
root> radio mimo show status group 1
MIMO group type: mimo-4x4.
MIMO group 1st member: slot 2 port 1.
MIMO group 2nd member: slot 2 port 2.
MIMO group admin status: disable.
MIMO state: MIMO-Disabled.
MIMO advanced state: disabled.
MIMO RFU role: slave.
MIMO 1st carrier MMI: -0.0
MIMO 2nd carrier MMI: -0.0
MIMO 1st carrier XPI: 99.0
MIMO 2nd carrier XPI: 99.0
