Can someone confirm for me it will do full 1.4G (aggregate) at 13Km with perfect LOS and snow/rain fade?
Some more facts/specs would be helpful.
If it can do this, it is an amazing product.

specifications are based on absolute
best case. And as you also seem to
know, the 24GHz band is subject to
Ubiquiti can't turn back the laws of
rf physics--as you well know. All the
other Ubiquiti radios are not able to
provide both full speed and full range--
why expect this one to? Dave

"revolutionary performance of 1.4+ Gbps, aggregate throughput and 13+ km in range"
I guess it should have said:
"revolutionary performance of up to 1.4+ Gbps, aggregate throughput and max distances of 13+ km in range"
Thought maybe the boys had pulled something off and once again shattered Einsteins Theory's.
Is there somewhere to see the specs on distance vs throughput?

The other AirMax product spec sheets show RX sensitivity vs different data rates.
This allows us to estimate the trade-off between distance and speed and TX Power.
The AirFiber spec sheet is quite different in that it does not include the information we need to properly design a link, or to advise a potential customer how fast his link might run.

In drier regions people may feel comfortable around 3 to 4 miles +/- at FULL modulation with an up time of 99.999%
Snow is NOT much of an issue with 24 GHz, primarily just rain, mdeium to heavy rain.
This is all just "conjecture" based on years of experience with other 24 GHz gear.
I plan to full evaluate the gear, I will let you know if I was correct? Currently I run a dozen or so 24 GHz links.
They really do work!

someone from ubiquiti please supple the rx sensitivity numbers so we all can do some link planning.
Exactly... I've got some shots in mind of more in the 4 to 5 mile range. I don't expect the full 1.4Gbps but I'd like something better than fantasizing about it (e.g. mebbe 500 to 800Mbps... dunno).

Hi!, i can give to you my experience statistics,
I depeloped a wireless link with AF24, the distance between the radios is: 6,655 m (21,834 ft), with the best alignment,(the best signal, and the same gain on all channels)
To get the max modulation (64 quam) i had to set the Tx power at 38 dB, and high gain in both devices... With this options i got a signal about 59-60. (all channels, both radios)
With a iperf probe i got a troughput around 650Mbps Full Duplex (real). The problem here is when a rain comes, the W-link suports without problem light rains, but storms with serious rainfalls the link gets down.
So i decided to put the link using 40 dB(México), the modulation keeps in 4x (16QAM MIMO) and i can pass trough allmost 500 Mbps but when the storm comes, the link goes to lowest modulation but still trough traffic.
With 40dB TX Power option the link gets down once, but the storm was really heavy!
