And as licensed spectrum has to be payed they are not cheap overall.

The lack of spectrum efficiency with the licensed bands
is my biggest beef with the inexpensive licensed links on
the market by Ubiquiti and Mimosa. Yes they transfer a
lot of data, but they do it by using very large amounts
of scarce spectrum in both H&V channels.

No, their site just sucks. Look up Test Report 1 for
SWX-AF11

Do you have to have some sort of Login for that? I just
return a plain 'You are not authorized to access this

My theory is that the AF11FX "40 MHz" channel used in
the previous example I posted is actually something like
33 or 34 MHz wide if you look at it on a $15,000 bench
test spectrum analyzer.

It is significantly worse... Look at the spec sheets.
Our old SAF Lumina can do 366mbps in a single polarity
256qam 56mhz channel... an AF11 doesn't even match that
running at 1024qam - it will theoretically do somewhere
around 340mbps at 1024qam and somewhere around 275mbps at
256qam.

If all you can get on a particular path is a theoretical
single 40 MHz wide FDD channel pair, one polarity, I
don't see how the 1024QAM bps/Hz efficiency would be
significantly worse than a competing single polarity
product (SAF Integra, etc) running in the same channel
size. Unless you are counting more expensive competing
products that advertise header compression and very
different Mbps rates for 64-byte vs much larger packet
sizes.
It's very cost effective so I will forgive it many
things, my main problem is that it can't actually use
near the full width of an 80 MHz channel.

Yeah. Cost is one thing, but if all you can get is a
single polarity on a particular path, the AF11 is
probably one of the last things I'd look at. Congestion
is a problem around here.

We're running the full 56mhz/MIMO... I haven't been able
to get them to run at 1024qam yet (antennas still need to
be fine tuned, it wasn't ideal weather conditions when we
put them up, so I'm hoping we'll be able to get a bit
more out them), so they're only at around 550Mbps
capacity (and I've verified the link will do around
500Mbps with real traffic).
Only 500 meg with two channels? Crap, I have an old
Exalt that can do that with only one channel at 256QAM.
