How about Dragonwave 18ghz or 11ghz? I think they make a 200mbps product
in both of those bands.

24 Ghz. won't do 5-10 miles.
The other option is an Exalt 2.4 Ghz. or 5 Ghz radio. 100 Mb Full
Duplex (Yes 2.4 Ghz.) for around $15-16K plus antennas

That depends on your perspective. We have a ton of orders and are
racing to service them all. The more we install the more capacity
upgrades we have to do meaning even more installs. This kind of
growth is extremely challenging because if it isn't done correctly we
can destroy the company.
Look at licensed. I know that is obvious but I think it is the only
way short of bonding Orthogons together. I thought the max distance
for 70 GHz gbps radios was about 7 miles. It has been a while since
I read the specs. I am sure the rain fade would be an issue here.
There is actually much less attenuation of 70 GHz than there is at
60 GHz. There is a spike of absorption of 60 GHz where water
molecules eat that signal. It gets better above 60 GHz. I believe
that you can go through the air better with as high as 100 GHz than
what you can with 60 GHz. Obviously there are other licensed options
in lower frequency space as well. I know Charles has some experience
running licensed high capacity backhaul. Charles, what do you run
for backhaul over 100 mbps FDX?
Licensed doesn't make a lot of sense for us. We simply don't have the
ability to predict where are growth is coming from. We routinely
upgrade existing backhauls and/or reconnect our POPs together in
different ways to increase our capacity and redundancy. With licensed
we are forced to have a static configuration.
I thought 24 GHz unlicensed had limited bandspace which made the top
end about 100 mbps FDX?
DragonWave seems to have a 24Ghz unlicensed product that can do
200Mbps full duplex.
