[ale] Outdoor Wifi - Water - The missing Detail?

[Alex Carver]

Yeah, plenty of documentation about the Fresnel Zone, interference
caused by intrusions into the Fresnel Zone, and calculators for finding
various performance metrics all over the innertubes. Every telecom
products or service company.

Here's a fun online calculator from Ubiquiti that uses Google Maps and
graphically calculates the Fresnel Zone based on local terrain and the
particular device(s) you're using. Other than registering, usage is
free.  There are better ones online that also collect all of the local
terrain and topology from buildings, trees, etc. but those are for a
fee.  There's a few others that are basic online calculators that will
produce a KML file to import into Google Earth for visualization but the
Ubiquiti one has live feedback on the map as you point at locations on
the Fresnel Zone diagram at the bottom. For probably the next best one
this calculator generates the KML file.

I own no stock or other financial interests in Ubiquiti, they just
happen to have cleaner interfaces and tools as you would expect from
former Apple employees.
