The Need for speed

Tue Jan 13, 2015 2:08 am

You know I saw a post on the UBNT Forums the other day about ClaudeSS getting excited about 70 Mbps with the new airMAX Rocket AC PTMP with a 20 MHz wide channel.

CORRECTION HE GOT THAT ON 10 MHz AS WELL - which is impressive
http://community.ubnt.com/t5/airMAX-Sto ... -p/1146365

I have been getting close to 70+ Mbps on 20 MHz channels and 97 Mbps on 30 MHz wide DFS channels for years, just check my OLD post on the UBNT forums.

Here is a speed test from my house tonight. :cheers:

Also notice the tabs open to the left of my speed test, those are some of the switches/towers my home traffic also has to go through. Remember we create a STATIC LAG between our routers and the WS-24-400A in each tower then make each WISP Switch interface a VLAN to a virtual interface in the router.

Here is a screen capture of my home speed test which is on a 20 MHz wide channel AP, a screen grab of my tower switch, and a screen grab of my home CPE.
We are running WISP Switches at every tower and they handle ALL tower traffic including AF back hauls. :hurray:
And all my radios even CPE radios use RF Armor. :thumbsup:

Chris -

My testing with the AC Airprism PtMP to a 19dBi AC Beam is just over 70Mbps actual throughput (to my NAS at home) under ideal conditions on a 10Mhz channel, 135Mbps on a 20Mhz channel, close to 200Mbps on a 30, and bumping 300Mbps on a 40Mhz. Laptop wired directly into NBE-5AC-19 connecting to a titanium sector an AC PtMP Airprism AP in the house.

I keep saying, if they got backwards compatibility rolling with UNII-1 and 2 certs, I'd replace every single AP on my network with these and stop buying M-series products. 64QAM is a hell of a lot easier to get also, and still good for about 45Mbps net on a 10Mhz channel from my testing.

We just installed an Airprism PtMP AP today hung on a 60º AC sector on our busiest site. The noise is ridiculous up there so we figured this would be a great place to give it a whirl.

I posted on the UBNT forum's about it here. While the old setup worked okay, AC works that much better. If only we could get certs pushed through for this product line!

That looks pretty sweet. Thanks for sharing.

You by chance have it powered by a WS do you?

Curious on the current/watts it uses under load/transmitting?

New chips could use less power than old chipsets, or could be more with the external CPU?

I do... This is my 'problem' hill I keep telling you about.

This unit draws an average of 7.5W it looks like! More power than the existing stuff I have up there. Not ideal for solar, but hell, for the performance, you can either cram a lot more users on a single AP, or offer higher speeds with the same number of clients!

average 7.5 but what about the spikes? old rockets spike to 12-13 watts average 5-6 watts

I've measured the power draw on the AC Rockets. When moving a moderate amount of data abt 60-70Mbps it pulls 8.5W.

When moving 100Mbps, bridge mode, R5AC-PTP draws 8.68W.

Okay, it's good to know the R5AC-PTP min and max along with the typical. Idle draw = 7.75W High draw (running speed test @ 100% CPU) = 10.85W

Just a note on the 60deg AC sector. It's got a big spike in gain in the center about 10 degrees wide that is ~21dBm, the rest of the sector is ~17-18dBm. Kinda caught me off guard, I was doing a link off at about 25-30 degrees and I was way under calculated.

I am getting some really good speeds in a 10Mhz channel also. 60-70Mbps. I haven't tried it, but ClaudeSS in ubnt forums thinks the Ti sectors are a better fit as they have a more even pattern.

I'm going to put up 2 RAClite on 2 little 5G16 next week, (note: need to get some armor on order) and see how it does there. I'm having trouble sourcing the NBEAC-19 atm though :(
