AirFibre Max Distance

So we received the brochure on the AirFibre and are still stunned that it says distances of 13Km+ at 24Ghz.
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.

Re: AirFibre Max Distance

No, of course it can't. As you well know,
specifications are based on absolute
best case. And as you also seem to
know, the 24GHz band is subject to
precipitation fade.
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
No disclaimer. Nothing to sell. I need to fix that.

Re: AirFibre Max Distance

Just by the brochure:
"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?
Thanks

Re: AirFibre Max Distance

+1 for more complete specs.
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.

The longest distance capable, always complies with the lowest useable data rates.

Re: AirFibre Max Distance

If you want my "opinion" 1.5 to 2.5 miles +/- in a region that see significant rain fall at FULL modulation and remains up 99.999% over a year.
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.

Re: AirFibre Max Distance

someone from ubiquiti please supple the rx sensitivity numbers so we all can do some link planning.

Thanks

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).
