Yes, absolutely - I should have said "AT THE LEAST' we need 5,10, 20, 40 available on all cross compatible gear. But yes, 15, and 25, and 30, and 50 are great options available on other gear as well. For sure, if Cambium wants ePMP to be as versatile as possible, then it should have 5,10,15, 20, 25, 30, 35, 40, 50, 60, 70 and 80.
AND whatever is decided with channel widths (even if it's just 5, 10, 20 & 40 available in all cross-compatible gear) then both 2.5ms and 5.0ms frames in all channel widths.
It would be really nice to have 10mhz channel width available in 2.5ms available.
30mhz would also be nice... and 50 or 60, but I'm not sure both would be necessary.
If I remember correctly, Cambium has said in the past that it's a significant amount of work to add in the addtional channel sizes, so it probably realistically isn't worth it to do anything beyond that.
Furthermore, I'd personally like to see the AC gear stay limited to 2.5ms frame lengths (assuming that's what it currently is... I guess I'm not completely certain), since that would encourage everyone to stick to the same settings for sync purposes. Actually, if the N based radios do get any additional channel sizes, I wouldn't mine seeing them limited to 2.5ms for the same reason.

Yes - for us in particular, this is an issue for us in the ePMP 2.4Ghz gear. There isn't enough spectrum in 2.4gz to be burning up 20 Mhz at a time, and we find that 10Mhz channels work very well for us, and can fit between the noise better anyway.
BUT this limits our choices, which is frustrating. We can't choose BOTH the best channel widths, and also choose to have lower latency. We need to be able to have 10 Mhz channels with 2.5ms frame sizes, particularly in the 2.4Ghz gear.
Also, while we are asking anything, the 550 should be able to make changes to one of the radios, without dropping the whole link on save/activate. That would make the dual radio product SO much more effective and valuable.
We should be able to be tweaking & optimising Radio2, and have Radio1 remain linked and passing data all the while. Then, once we had Radio2 dialed in with the best channel & width, we should be able to leave it online while we go back and optimize Radio1. The way it is no, pretty much any change to either radio, tears them both down. (sad face)
Hi Ninedd,
We will have the 3000L announcement very soon!
I can't say too much, but it will work a little bit differently than how we have made our lite models in the past.
It is basically an 802.11AC wave2 chipset with 2x2 instead of the full blown MU-MIMO with the normal 3000 AP.
Stay tuned in the next couple weeks for more information, pricing, and availability!

Yes, I appreciate that. They told me the same thing. I do get that, and I do appreciate that. I'd remind them that it's also a significant amount of work for us WISPs to be out there in the wild, trying to maximize spectrum use, and throughput, and performance, and to mitigate interference, and optimize latency, and...
This business is a lot of work for everyone involved, and on the front lines, we need the tools to deliver the best to our clients. For channel width's, we at least need compatibility between N-chipset gear and AC2-chipset gear's channel sizes and frame sizes. It does no good to work on Force300 compatibility to an ePMP2000 AP, if we're not going to also have compatibility with the ePMP2000's channel widths.... at the least. So that at least means 5, 10, 20, 40 widths in both 2.5 and 5.0 frames, on both N-chipset (2.4ghz and 5ghz) and AC2-chipset gear. Otherwise 'forward and backward compatibility' isn't really achieved.
And I want to add... I say these things from love. :) I'm not just complaining - I really, really, really like a ton of things about Cambium. If I didn't, I wouldn't be here commenting, I would have moved onto something I like better. The fact is, Cambium kicks butt in so many ways. The RF and 'secret sauce' is amazing. So when many of us are saying we need things that other vendors have, that's coming from love and from wanting Cambium to have everything (and more) than any other offering. :)
Hello
in ePMP2000 sector and force180/force110/force200 as client I see the latency to be too high. 17 to 30ms.
link distance of 1.3 Km.
Why in TDD mode the Latency is always high?
Parfull,
Welcome to the forum. I think you know the answer already :) Its a 5ms frame so at a minimum you will get 15 to 17ms latency which will often go up when you have other data as ping is not prioritized.
Pleaswe work with Sreejith to get a full deep dive on this topic.
Hello, Please i urgently need an Acceptance test Plan for one of my customers, immediately, can you help
Acceptance Test Plan a for Epmp 3000 Trial....
Please email me off line with details. What product? What type of test plan etc? What region?
