If you are selling radios that need licenses, I would think that perhaps you 
should get some kind of bulk deal and pass the saving along to your customers.  
Radio, antenna, license – all in a package for one simple price.  

Right now we buy the car at one place, then we go across the street and buy 
tires and put them on the car, then we push it to the gas station for gas.  
Ford may not be in the business of refining petroleum or making tires, but can 
certainly drive the car off the lot.  And in all cases in recent memory the 
dealership also does everything necessary for obtaining the license plate too.

>>.I should have caveated that, b11 is crummy. 

Here is the part that I love about the WISP's... Everyone is Opinionated to the 
Nth degree without explanation or possible understanding of why they have such 
an opinion..... and that is ok, as long as it is expressed in that context ... 

As an engineer, I tend to dismiss all opinions, unless the person offering the 
opinion can offer an explanation which has some sound technical backing to 
support it.. Similarly, I also tend to dismiss the "I love it" opinions, unless 
they are backed up to the reason why.

I am happy to see lots of options in the market space, no one can please 
everyone ..... FWIW, We use gear from many different mfg. each for their 
strengths, and not their weaknesses. We find that each of these products shine 
in the different ares of the three common requirement that everyone has.. Needs 
to be Good Quality, Fast Performance, and Cost Effective..

In regards to the debate about Freq., I will suggest to the OP that do a little 
bit of reading on the fade characteristics of different Freq. is, this is 
physics, and totally vendor agnostic, and this will greatly help you in  
gaining  a better understanding of what is the difference one can expect 
between 24Gz/23GHZ/18GHZ/11GHZ/6GHZ etc.. for their deployment region.. (I 
agree with Steve, in regards to the missing context of rain zone, and I also 
agree with Mike H.. that Rain zone's are a rough guide, not an absolute ref  ).

I am a bit puzzled about Chuck M's comment about the Cost of License being high 
? and a desire to purchase a 'bundle' which includes coordination etc... I 
would like to see if Chuck can elaborate a bit more on this... 

:)

Happy Weekend.

  I should have caveated that, b11 is crummy. I havent seen much bad about the 
5ghz stuff

    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).

          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:

              a.. 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
              a.. 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
              a.. 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.
              a.. Any oddball items we should take into consideration other 
than the ones already mentioned here? Or are we missing some obvious questions?
            �
