AirMax vs Osbridge Polling?

[Bero]

How AirMax looks compared to Osbridge WPM Polling?

[WHT]

For U.S. users, its a moot point as Osbridge pulled out of the U.S. market, as my understanding for FCC compliance issues.

[Bero]

I`m asked for technical aspects.

ps. I`m not a U.S. user.

Well,

I have like 160 OSB 5gxi on my network. With polling and without it. At these point it's to soon to determine what it's better.

Airmax it's totally new and OSB ran polling before with the 5Ghz units, UBNT start with polling with the N products. Actually OSB will have now his own N units with good performance too dual polarity. I have experience with Nstream to that I am testing with N and my feedback it's the following:

With a lot of noise the best so far that works it's Nstream also with point to point for cctv camera it's a plus

The actual polling of Airmax sounds good we don't to much info in a real enviroment of Multipoint. Sound goods from know and the actual Polling protocol in noisy enviroment we get less bandwidth compare without it.

Osbridge in the other side Polling rest a lot of bandwidth for the end users you can connect like 50 clients per sector and stable latency but the performance normally you get like 3-4mbps more than that with 30 clients connected to the sector in my experience.

So when we tall about polling the only one out there that it's really working it's Motorola Canopy.

OSB - more client less bandwidth, stable latency
Mikrotik - more bandwidth, more clients, erratic latency 2ms-25ms,30ms,2ms...
Airmax - work better with interference like nstream, less bandwidth sometimes that with it. Latency more accurate that with nstream but in a point to point at these point I don't have any sector with 10 clients with Airmax.

Canopy - Good latency, stable ping, (low bandwidth platform and expensive)

too soon to determine if any one have 4 sectors with 300 of client right know that can share the info it's welcome.

I know that TDMA Airmax will be great, but for my experience it's too SOON.

Note that AirMax only runs in new 400 MHz units; may be if all remote units of MT nstreme would be that class of processors or higher(i.e., RB433AH), the latency would be less erratic. People complain that Ubiquiti broke backward compatibility in not implemeting AirOS V in older units, but that may be actually a good thing.

As for polling, pre-WiMAX systems like Alvarion VL and Aperto PacketMax are also good options to Canopy systems.

I can understand the frustration in lack of backward compatibility, but to say UNBT broke anything is unfair. There comes a point that you simply can't go forward with new technologies and maintain legacy support.

The reality is that AirMax simply won't work on the earlier units. Would you really expect Vista to run on an old Intel 80386 CPU with 640 KB or RAM on the board.?

When the automobile was first introduced, there was a law that required a person to walk ahead of the car with a red flag to warn oncoming horse driven carriage a car was approaching. That was an attempt to make the automobile compatibly with the legacy horse carriage.

hi,

at least you can mention other manufacturers pros/cons on here without getting a forum ban :)

Mikrotik - more bandwidth, more clients, erratic latency 2ms-25ms,30ms,2ms...

This has been corrected many months ago. You need to install the new version of nstreme.

Well first of all, I have experienced with all of those. I know the Airmax will be great! Time will speak!

For: Ron

I have a few link using Mikrotik Rb433AH with version 3.20 or later. All my router haves 3.25 or 3.28 I will try to upgrade one of the wireless link and I will let you know if really change something with the Nstream stability.

I don't know whay the people cry for backward compatibility it's a totally new product Airmax.

Ivan, if you load wireless-test on 3.27 or 3.28 the latency problems disappear.

Hi,

Good to know, I have 3.27 & 3.28 in all my routers but not in the wireless links.

I will try and let you know! =)

Thanks George.

Ivan, if you load wireless-test on 3.27 or 3.28 the latency problems disappear.

George

ditto... i loaded the wireless-test package with nstreme on all of my wireless towers and the latency went from 30-50ms down to 5-15ms..

[kijoma]

hi,


if you rename the package to wireless from wireless-test before you upload you also wont get the surprise of the router rebooting with the new package disabled!
