Tim, I am not sure if you are talking about OFDM or DSSS. With OFDM, you DON'T need LOS. Of course its not going to connect forever with NLOS, but for a few miles, it is a no brainer. We have ample empirical data that proves it.

OFDM of DSSS will handle interference (ie. "smearing" ) of the signal better with the lower symbol rate. Things like multipath will be less of an issue. Still an issue, but less pronounced.
