Trango, SAF, Exalt, etc. Typically 250Mbps FDX @ 40MHz/256QAM. And
360Mbps FDX @ 56MHz/256QAM. Give or take a bit for things like strong or
weak FEC, ACM enabled, etc.

What other radios will only do 250Mbps (502.4Mbps capacity according
to the data sheet...) on one 40mhz single polarity channel at 256qam?
The other's I've looked at are typically around 300Mbps...
Not that I'm saying the AF11 is a bad radio, I plan on putting up at
least a few of them this year... but I find it a little funny that
they use 1024qam as a selling point, when it can't do as much
throughput at 1024qam as other radios do at 256qam.

I think this whole thread can be summed up that there's no magical
way to get around the shannon limit and bps/Hz coding efficiency
for a given channel size and modulation... From the technical
perspective of people who have to really understand the FDX
capacity of a new PTP link, the ubnt marketing department is
divorced from reality, it's not 1200 Mbps no matter how many slick
PDFs they publish.
One 40 MHz channel single polarity at 1024QAM 5/6 code rate is
going to be nearly the same efficiency bps/Hz from many different
manufacturers. Multiply as necessary for dual polarity or for
larger channel sizes such as 60, 80 or 112 MHz.

FYI... on a "single" 40mhz channel 'dual polarity' (mimo) the
expected throughput on Af11x is 500meg duplex.

But if I can get 80mhz channels in both polarities
(running at 56Mhz/1024QAM with this radio), I should be
able to at least double he capacity of my PTP-800 link
which can do 228Mbps. Right?

At 40 MHz and a single polarity, you're looking at an
almost insignificant increase in throughput.
Their claim is 1.2 gb+.
Cut that in half as they're advertising the aggregate,
so 600 mb+.
That's using both polarities, so now only 300 mb+.
Only I haven't heard of anyone getting much more than
500 in a single direction (they may certainly exist, I
just haven't seen them), so now that 300 is really
only 250.
Not much of an upgrade unless you can also get larger
channels in both polarities.

This PTP800 is only capable of running at 40Mhz
(ODU-A) so it can only do 228Mbps full-duplex. The
AF11x should be able to do much more than that, right?

IIRC, PTP800 is Remec Style, you'll need Remec to

What do you expect to achieve with this upgrade?
Not much capacity difference between PTP800 and
AF11x, maybe 50-80- mbps more. Only if you have a
xpic license you can double your throughput with
the af11x

Good news - thanks for sharing.
Somewhat un-related question:
I have a PTP-800 link using these dishes:
http://www.hol4g.com/AC/product.aspx?number=ANC-VHLP3-11W-RR1&p=237127&sc=0
<http://www.hol4g.com/AC/product.aspx?number=ANC-VHLP3-11W-RR1&p=237127&sc=0>
Do you know if I can re-use these dishes with the
AF11x? Do I need adapters?

Hey all, just dropping by to share our
experience with AF11x, we habe been beta
testing the unit since Sept and for the last 3
months, the unit has been rock solid.
We are very happy with its performance, just
wished it had a SFP port!
This unit replaced a Mimosa B11 unit that we
were having some intermitent throughtput issues,
The swap was easy since we reused the Jirous
Dishes and only had to add the af11x adapters
to it,
The link went live on 9/21/16 and on the
first weeks we experienced some lockups, but
after a revised beta fw was applied, all
issues went away.
For UBNT, please add SFP port and continue the
good work towards a af6x and af18x
