I don't know that anyone has really examined the overhead required by
OFDM (AF11) versus the overhead required by the various other licensed
vendor proprietary modulation schemes. I think this would be the primary
issue. I know we get over 500 Mbps through a Dragonwave on a single 50
MHz channel. Two channels should theoretically get over 1 Gbps. The AF11
comes out of the chute doing dual polarity, so that would be the comparison.

If all you can get on a particular path is a theoretical single 40 MHz

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

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.
