Seriously, these questions, please, please, please! State your rain region.
Here,. id like to punch anybody in the eye who lies to you and tells you 24
GHZ is a good idea over 1.2 miles ( I dont care the KM Im mercan) but some
guy in a desert might tell you its an awesome idea at 6 miles, I dont care
about him here, he doesnt care about me there. If you get into the higher
frequencies yout rain zone, it really matters.
but when it works, it works, and in 24 GHZ right now, theres nothing on th
market that compares to AF, even if you skimp on the HD. Literally
nothing.... Ive looked. you can pay 10k with the other actual carrier
classes for 200mb... just not worth it, if 24 works to go anywhere else.
You have to remember, UBNT 24ghz (airfiber) is NOT a UBNT product, its a
Motorola product. Just before Motorola shit canned, UBNT bought \theirguys.
11ghz, totally different beast. you OWN the channel, and you can be a dick
about it. Like central Illinois wanting to put up a link. If your in
central Indiana, you can contest... This is fact, we just had to trade off
10db to get a link because it was contested 100 miles away, because our max
EIRP could impact that link during its lowest rain fade hundreds of miles
away. Im not complaining, if I had their GIS and hired guns, I would have
done it too.
however, I literally can come in across the street on your 24 ghz link, put
it on the same channel as you and just pump out on maximum power all day.
You know what you can do? you can go to Starbucks, get yourelf a nice
double frappe vanilla bean, half caf, choco humpagoat with double froth,
and take it to your shop, set it in the middle of your chair and sit on it
while humming Mary had a little lamb. Thats it, thats the end of your
recourse.
And dont ever talk about Mimosa again. Its garbage. If I was going to put
another link up outside of what I can do again, I wouldnt touch Mimosa, not
if the Mimosa CEO sent their grandmother to service me and thirteen of my
friends. The only reason to put Mimosa up beyond 3 miles is to lawfully
squat some spectrum on the cheap.
FWIW
Harshish words, I know, but this is all stuff I learned the hard way, Im
only a decade into this nonsense, I wish some prick had shown up and
smacked me like a wife who didnt have the pot pies in the oven on time long
before I made some bad decisions, You have to treat all your gear like a
woman. Know where you are and what her scope is in that area. Dont go full
bukakee on a housewife.
