Not only that, but the Atlas isn't capable of 45Mbps in any form much less
FDX.  Most we've ever seen out of an Atlas is maybe 20Mbps HDX with very
clean air.  Add a little noise to the equation and that puppy will auto-rate
itself down to the 10Mbps neighborhood in a heartbeat.

Believe me these "up to" or "best effort" radios are tempting, but until you
deploy a few $15k - $30k PtP radio sets that actually produce what they
claim you won't understand what we're talking about.  

When I say "you" I'm not directing that at anyone in particular just a
general comment.

Best,


Brad

Tom,

You're gonna bond 2 atlas links and get close to 100 Mb full 
duplex?????   How is that?? 

The 200 Mb Exalt is 100 Mb TX /100 Mb RX

If you use your  equation you really need 4 Trango radios which is 5 x  
$3000 = $15000 and that will give you 100 mb with 50/50 MIR.  Not to say 
what you would use up in spectrum (20 Mhz. x 5 = 100 Mhz......OK...you 
could play with polarity with good antennas and probably do better).

So the Exalt doesn't look that expensive after all........  :-)

And BTW:  I was told to expect MIR control for asymetrical bandwidth soon...
