Hi Patrick:

Good paper, but the claims of NLOS are exactly as I thought they would be. 
Significant multi-path enviroments which have strong signals, such as offices 
or dense urban spaces. I didn't see any claims of the signal being able to 
burrow through an isolated hill on a long distance/weak signal path in a rural 
area just because it is using OFDM.

None-the-less, there still may be an advantage for signal limited long distance 
applications. You might want to go back to the author and have them add a 
section about Fresnel zones (which itself is multipath/signal cancelation). I'm 
not sure OFDM would help there, but suspect it might depending on if we are 
looking at bit smear or waves 180 degrees out of phase. Then if you could prove 
this, you'd have a paper you could universally apply to the long distance 
suburban/rural operator as well as the urban hot spot/office crowd (which is 
all it addresses now).
