cnWave provides consistent high bandwidth internet in dense urban environment. It is a 60GHz, multi-node wireless Software Defined Network (SDN) that enables high-speed internet connectivity in multiple environments. cnWave is a high-speed backbone network to which other networks are connected.
throughput numbers provided above are bidirectional numbers considering 50/50 for uplink and downlink in mesh network. There is a plan to support asymmetric throughput in future for PTP links.
Tools used-
Iperf version 3.7 for bidirectional support (widely used)
I have a V3000 to V3000 PtP link with a 661 meter distance. I recently upgraded to software version 1.2.2 and wanted to test the new channel bond feature. The POP is running E2E controller onboard.
I wanted to use the devices to test, and I wish there was a “link capacity test” like the PMP450 product line. I came across this post and discovered the next best thing for what I need.
I used PuTTY to SSH into both sides of the link, with the same username and password as the web interface.
On the POP side I ran:
service iperf -s
On the CN side I ran:
service iperf -c [ipv6 of PoP] -i1 -fm -w128k -P 16 --bidir
Then retrieved the output on the CN:
system iperf show
Some of the output is shown below (it looks like it runs several iterations).
I had to SSH into the POP a second time to shut down the iperf service, using the command:
system iperf kill
system iperf clear
I don’t know how much of what I discovered is “proper” so to speak, but thought it might help someone else who wanted to test without downloading software onto multiple computers, or else just wanted a unit-to-unit test.
In fact, if Cambium would take a suggestion, it would be great to incorporate a test like this into the web UI. It’s clear that the units themselves can support it using the CLI.
