I think both Julian Kemp and Daniel White both did rain presentations at
AnimalFarm in years past. Fascinating with the shape and size of the
raindrops, and the fact that some places have continual drizzle and some have
torrential sky floods but both will show the same amount of rainfall.
Certainly not as simple as looking up rainfall specs for a place.

SEA is amazingly friendly. They get rain but not very intense.
What makes it particularly challenging is that it is rain specifically across
the path of the link. So a 1km link that follows a typical squall line path
will be different than a 1km link that is perpendicular to the typical squall
line (partial path with rain vs. full path with rain). It's cool stuff like
this that makes it so much fun! :-)

Move the decimal 5 places = 5.296 minutes per year
25.9 seconds per month.
So should drop for a second a day or perhaps for half a minute a month or 7
seconds a week etc etc.
Be interesting to see what folks in Seattle actually see.

that is good for five nines reliability at 500 to 650 meters in a
Seattle-like rain zone. Somewhat less distance in places that have higher
mm/hour rain rates. These are serious products that take direct 48VDC power,
singlemode fiber connections, and have dedicated management interfaces.

IgniteNet does all of that too.

Please don't let your impression of 60 GHz be influenced by IgniteNet's silly
USB dongle in front of a reflector, cheap stuff...
Bridgewave (REMEC/Mosely) and others make much more expensive, carrier grade,
fiber-connected 60 GHz PTP equipment that is good for five nines reliability at
500 to 650 meters in a Seattle-like rain zone. Somewhat less distance in places
that have higher mm/hour rain rates. These are serious products that take
direct 48VDC power, singlemode fiber connections, and have dedicated management
interfaces.
"serious" 60 GHz equipment is built to the same standards as $15,000 80 GHz
links and is used by a lot of large ISPs. Most of whom don't consider
themselves to be WISPs, but rather ISPs that happen to use PTP millimeter wave
when it is necessary or justified.
I have not personally seen a Metrolinq 60 GHz but I have seen photos of one
disassembled, and it is literally a USB 802.11ad 60 GHz dongle hot glued to a
plastic thing in front of a reflector. Scary.

Let me back up.
We lose our IN link every time a bird pees. It generally holds up during
torrential down pours.
Random fog events will cause it to become trashed.
The link is .6 miles. I expected it to fade from time to time. The problem
for me is the fail over does not happen properly.
It's a gosh darn USB dongle attached to a reflector dish. Don't expect too
much out of it.

I disagree. We lose our IN link every time it rains. And the 5GHz does
not fail over seemleasly at all.
There is packet loss and high pings until the 60GHz finally dies. Then it
sometimes flips.

Between 50-80GHz, oxygen attenuates the EM spectrum significantly more
than water. Not to say that it doesn’t contribute at all to fade, but at 300
meters you’d probably only ever go down if Poseiden himself took offense to
your client.

Is rain fade an issue?
I just read an article claiming that the atmospheric attenuation at
60ghz is so great that at any range where 60ghz will operate the rain fade is
insignificant.

Yes, and the LR brackets. They should just drop the regular

I have a 1300 meter link on PTP60-35 radios doing -59/-61. Very
happy with them. The mounts they come with are trash. Get the “long range”

I have a microwave shot about 3 blocks long, so 60ghz seems like
an option.
Have any of you tried IgniteNet? Has it been reliable for you?
I don't actually need a gigabit in this case, I just need it to
be up.
