AirMax AC-Lite Results

My in-house testing of the new line of AC products show:

20Mhz - 144Mbps (173 OTA)
40Mhz - 307Mbps (400 OTA)
50Mhz - 383Mbps (494 OTA)
60Mhz - 467Mbps (612 OTA)
80Mhz - 580Mbps (867 OTA)

Due to spectrum constraints at both locations, I was only able to test 20 and 40Mhz channels briefly on a 14 mile link.  I was able to pass 138Mbps one way at 20Mhz and 247Mbps on a 40Mhz channel utilizing 2' rocketdishes fully shielded on both ends.

Looking good.  TCP or UDP?  Iperf across link through ethernet yadda yadda?

Correct, UDP iperf across the link.

What does single/multi stream TCP look like?

I didn't get to test that unfortunately.  Waiting on this new 14 mile site to be approved.  I was parked illegally on a loop around a hill with an inverter, a tripod with a pole and an AF5 unit on it sitting on the side of the road with the truck running.  LOL  I had to pack up and go around the loop a few times and leave my buddy with the AF5/tripod setup on the side of the road so I could come back around and 'park' on the one way loop.  I'm hoping to have more tests to the actual location we're mounting, but that was the best I could do.

Re: AirMax AC-Lite Results

Nice! Our test units are supposed to arrive on Tuesday, I'm definitely looking forward to seeing what they can do. How are you finding AirOS 7? Is it sufficiently similar to AirOS 5.x that the learning curve won't hurt too much?

You'll love them.  Ver 7 is cake.  All it is, is a very clean version of 5.  Options are nearly identical.

Re: AirMax AC-Lite Results

Are 30 MHz channels supported in the current release?

Nope.  Not yet.  Just the channel widths I posted.

I'm looking forward to a TCP test... Especially full duplex test.

Re: AirMax AC-Lite Results

I'm betting a 15% or so drop in performance with TCP.  Wish I would've had more time to test.

Re: AirMax AC-Lite Results

I'm curious where in the real world one would find 50Mhz or greater available spectrum to setup shop??

Re: AirMax AC-Lite Results

So has the new AC stuff been approved for the 5150 - 5250 spectrum?  Assuming the answer is no.  Would be a hell of a surprise if so!

Re: AirMax AC-Lite Results

What frequencies do the AC airmax product line support currently?
Will DFS be available on AC airmax products?
Will 5.1(unii-1) be available on AC airmax products?

Re: AirMax AC-Lite Results

No approval for that yet.  I'm sure it's on the to-do list but we're all playing the hurry up and wait game with the FCC so... hurry up and wait.

Re: AirMax AC-Lite Results

So just U-NII Upper (U-NII-3): 5.725 to 5.825 GHz for now?

Re: AirMax AC-Lite Results

Let me check, I need to plug them back in and I'll let you know.  I tested them in the upper band for PtP over 14 miles so can't say about middle band.

Yes, confirmed, Rocket M5 AC Lite - ONLY U-NII-3 Band for now.

Re: AirMax AC-Lite Results

Our test units just arrived. :-) AirOS 7 really is just like the 5.5.x line, but with a more modern looking UI. It still has the annoying "wait while the whole unit reboots because you changed the password" thing going, otherwise it's pretty slick. We did some very quick testing with "duck" antennas from some UniFi 5 gear across the office, with the power turned WAY down (to -4). I'll write up something more complete later, but initial testing confirms @WisTech 's findings: these things are really fast. We only used the internal speed-test until we get some hardware moved around, and across the office with duck antennas makes for a pretty poor connection - but speeds were really good even then. 75+ mbit/s on 20 mhz, 150 mbit/s+ on 40 mhz, and the rockets ran out of CPU testing larger channel sizes than that - stubbornly refusing to go above 300 on the internal speed test. All tests were full-duplex; running them again half-duplex showed almost exactly the same speed, but in one direction rather than split between the two (so 300 down, or 150/150).

A few other things I spotted:

  • 30 mhz channels aren't available, curiously enough.
  • It's upper-band only for now.
  • It looks like WDS is on, no matter what (not a bad thing).
  • Some of the options I'm used to seeing such as alternate data rate and channel shifting appear not to exist in AirOS 7 at this time.
  • The internal speed-test gives real-time feedback on speed while it runs, except on advanced "transmit-only" tests - where it appears to lock up completely and suddenly gives you an answer.
  • I couldn't find AirView anywhere. Did I miss it?

Overall, based on an initial 10-minute testing session color me very impressed. We're planning a proper bench-test later today (or tomorrow, depending upon call volume) - and I'll post a proper write-up. Based on this quick-test, I suspect we'll be using this to replace a congested back-haul link next week. I'm not sure where this leaves the AirFiber 5; it seems like these can get pretty darned good results for a fraction fo the price, without eating an enormous chunk of spectrum to get there.
