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:
1. Licensed, should be clean spectrum for the full term of the
license and require less babysitting for interference
2. 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
3. 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?
