Actually, not sure if that was the product. IMHO OFDM alone doesn't give you any intrinsic advantage for highly directional NLOS paths.
I'm still looking forward to seeing this white paper, but suspect it will put alot of conditionals in the equation to come up with the conclusion. A less then optimal path, in a closed office enviroment, with plenty of multi-path... that I can see them making the case. But a long distance point to point link, with little multipath using highly directional antennas? Then again, maybe they are assuming you are using a cluster of buildings in between as a reflector, and then illuminating them. In that case, we would have a signal that would have plenty of multipath on it. Then I can see the case being made.
