What is WLR Mode?

I am a Ubiquiti shop and have gotten some ePMP 4525 SMs and should have some 4500 APs soon to test as a possible replacement for AirmaxAC. Looking at the SM I see it has two modes. One is a PtP mode which is pretty self-explanatory. The other is WLR mode.

Looking at the ePMP3000 documentation, as there is no 4500 documentation, I do not see WLR as a possible mode. Also looking at other threads it looks like TDD will be coming to the AX PtMP line later in the year.

So is WLR just standard 802.11ax or is it running a Cambium specific protocol with tweaks? What are the limitations or features of WLR driver mode.

I know Mimosa’s recently released AX equipment also does not have TDD yet and just appears to be running 802.11ax wifi mode. Is that what WLR is as well?

I don’t know about Mimosa but Cambium’s WLR (WiFi Long Range?) is proprietary and last I knew it only works with other Cambium radios that have the WLR option… I have no idea what its purpose is.

WLR is 802.11ax based protocol but it’s optimised to operate in outdoor scenarios on long distances with multiple subscriber modules.
WLR doesn’t support GPS sync.
TDD is coming soon. We are running an Alpha testing in a field right now.

Thank you


Will the 4500 radio support AC radios… ie Force 300 25?

Yes, but not quite yet.

Just like Cambium did with the AC deployment map, the first release for the Force 300’s were PTP only, followed by 3000/300 greenfield, and then followed by full Forward & Backwards compatibility.

So, from what I understand, that’s the deployment plan for 4000 series also. Cambium started PTP with the F400/F425, and now have 4500/4525 shipping for greenfield, and they are working fast & furious on TDD (in alpha testing) and then on to compatibility with Force 300.
