Testing MU MIMO performance - No reboot required
Multi-user multi-input multi-output (MU MIMO) is used to multiply the capacity of a wireless connection
with no need for additional spectrum.
If you have deployed MU MIMO at your site, you can test its performance in a lab environment using one
of the following methods:
l
Web user interface (UI) of BTS
l
Linux setup - iPerf server
Before testing the MU MIMO performance, make sure that your lab environment contains 1 x BTS and at
least 2 x CPEs (which are installed such that the spatial frequency is at least 128).
Following sections describe the methods used for testing the MU MIMO performance in a lab
environment.
Web UI of BTS
You can run a link capacity test using the Tools page of the B1000 UI. Determine the MU MIMO Control
mode (enabled or disabled) for CPEs before running the link capacity test.
To run the link capacity test for the required CPEs, perform the following steps:
1. From the main B1000 dashboard page, navigate to System > Radio.
The Radio page appears.
2. In the MUMIMO Control field, select Disabled as shown in
Figure 27
.
By default, this parameter is enabled. 112 MHz is selected as an example for bandwidth.
