Mimosa 5 GHz works great for me. Don't use shit antennas.

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.

Our experience has been we get more throughput and more reliability from the 
AF11 than the B11. The B11s always seemed to be choking on high throughput. We 
gave up on them, and the AF11s are easier to license in congested areas anyway.

Yes, the AF11 can do more throughput on the same spectrum compared to the B11, 
but the B11 can use more spectrum (a lot more, granted), so it can do more 
throughput than the AF11 can. You can get close to a full gig in one direction 
with the B11 (assuming you can license enough spectrum), but you can only get 
around 650Mbps in one direction with the AF11 (it's a real full duplex radio 
though, so aggregate isn't that much different if you need a 50/50 split).

What others have said about distance. Short (up to 3 miles or so) 24 GHz. 
Medium (up to 8-9 miles) 18 GHz. Long (up to 20 miles) 11 GHz. Longest 6 GHz. 
I disagree with the B11 versus AF11. The AF11 will provide more throughput on 
less spectrum. Probably less expensive too.

I know this topic has come up before, but thought I would throw it out again to 
hear additional thoughts as products continue to evolve.�� We have been 
doing primarily 5 GHz backhaul using Mimosa products for the last couple of 
years.�� Their frequency reuse has really helped us, but we are starting to 
see more locations that have lots of noise.�� We�d like to make the jump 
to higher frequencies and are looking at 11 GHz and 24 GHz for that.�� The 
links we need are fairly short, 6-10 miles max, which pushes the limits of the 
24 GHz solutions, but with a very clean line of site we think we are in range 
for the links we are looking at as far as the design tools tell us.�� For 
11 GHz, we would likely stay with the Mimosa product line, we know it pretty 
well and have all the management tools in place for it.�� For 24 GHz we�d 
likely go with the Ubiquiti AF 24 or AF 24 HD.�� We have worked with 
Ubiquiti stuff here and there, and just don�t have much familiarity with any 
other options outside of AirFiber.� Here is where we see the Pros and Cons of 
the two options: 
� 
Mimosa 11 GHz Pros: 

    1. Licensed, should be clean spectrum for the full term of the license and 
require less babysitting for interference 
    1. Should support longer links, but that isn�t a big consideration for us 
as it looks like everything we will need is under the limits of the HD for sure 
and likely the AF 24 as well 
    2. Little less susceptible to rain fade 

� 
Cons: 

    1. Have to mess around with the license and there is a cost associated with 
it 
    2. Have to buy the dish separately, and know which to use before applying 
for the license 
    3. Not quite as much throughput (when compared to the AF 24 HD) 
    4. More expensive that the AF 24 (but likely a little less than the HD) 

� 
� 
Ubiquiti AF 24 Pros: 

    1. All in one unit, easy to figure out what to have on hand for all links 
    2. No messing around with licenses, making it much quicker to deploy 
    3. Higher throughput on the HD 

� 
Cons: 

    1. Unlicensed.� Might fight other noise out there, and even quiet links 
now might have noise later 
    2. Not as familiar with this tool set as we are with Mimosa, although this 
isn�t a big consideration as we have worked with lots of Ubiquiti products 
    3. Cost of HD is pretty high for an unlicensed link 

� 
Here are some questions we are hoping for help with: 

    1. How much room in the unlicensed band is there to move channels if you 
see other noise out there?�� We have been looking but are finding it tough 
to figure out if we run wide channels, and see noise, will we be able to move 
to other channels. 
    2. Is it reasonable to think you can push 1.2 aggregate IP traffic across 
any of the three options B11, AF24 or AF24HD?�� Seems like a well planned 
link with great line of site at 6 miles should be able to, but looking for some 
real world experience. 
    3. Any oddball items we should take into consideration other than the ones 
already mentioned here? Or are we missing some obvious questions?
