 When I think of the benefits of using something like Direct Sequence
 Spread Spectrum modulation over visible light frequencies, with
 bandwidths in, say, the terahertz range, I don't see any reason why an
 advanced civilization would be emitting much radio at all. Worse yet,
 such a signal would look just like white light, or starlight, or any type
 of source desired. It would not be decipherable or even detectably
 artificial unless the transmitting folk wanted it to be. For that
 matter, any number of "stars" we see could just as well be transmissions.

Is there a place I can find out more about this on the web? Like the
potential uses of frequencies in general also, etc..?

thanks
