Maybe I'm missing something -- but w/ LICENSED Dragonwave 50 Mb radios as
low as $8-9k / link, unless you're going to shoot 15+ miles (which isn't
really possible w/ the amount of spectrum utilized) why would you even
bother messing around w/ such a high-priced unlicensed radio?

-Charles

P.S. -- Bob, can you ping me offlist w/ your contact info, need to ask you
something

Bob,

They way you wrote it, you are correct its not to bad at all. My post was
based on what I thought I read from someone else's post that 
stated that the 200mbps model (raw) pushed 100mbps of throughput (real), I 
was assuming based on waste of protocol overhead like Wifi.  Trango has a 
very efficient MAC with little waste.  If the the Exalt does real throughput

of 100mbps in each direction, than that is a completely different animal and

value proposition.  And getting 50mbps Full Duplex in 32Mhz, also might be a

speed leader in unlicensed.

Bob, have you confirmed actual real throughput?
