Buying cheap is buying twice (and mounting). Dont know what your license
cost is. In Germany it would be 6kEuro for 56MHz x 2 V+H for 10 years.
Looking at cheap lastgen licensed gear like e.g. SIAE Alfo+ the difference
is not that much.
Blocking frequency does only make sense where regulations does allow
inefficient/interfering gear. I would not get a licensed frequency for a
Wifi-based Radio like Mimosa. With higher quality gear you could reuse the
frequency every 30 degree. So there is more free spectrum to use.

Yeah, I really don't see it as being an issue with the
AF11. With Mimosas,
the fact that you're having to license both channels
both directions,
certainly has the potential to cause problems trying to
coordinate around
your own stuff, and that's not really going to be
particularly useful as
far as the "reserving" channels argument goes. But with
the AF11, they're
operating exactly the same as a normal licensed radio
with a (technically
two channels, if you're using MIMO) transmit channel and
a receive channel,
so going to a more efficient radio is going to just be a
direct drop in...
it's really not the worst thing to use a spectrally
inefficient radio on a
link that's probably going to need to be upgraded to
something faster in a
few years from that point of view.

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

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

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.

Congestion is a problem around here.

Only 500 meg with two channels? Crap, I have an old
Exalt that can do
that with only one channel at 256QAM.
