Do I have this right? Neutrinos are fermions, carriers of mass, and therefore have no wave characteristics in the two-slit experiment sense. Seems to me that "neutrino radio" is a misnomer?
All particle, whether fermions or bosons, are waves. The difference is that fermions can't pile up on top of one another like bosons can, which means they can't form macroscopic classical waves, like light or gravity. This is probably what you mean when you say that "neutrino radio" would be a misnomer. Normal "radio" consists of radio waves, which are macroscopic collections of many, many photons. In principle, you can measure these waves by watching how they tug and pull on charged macroscopic objects.
However, the sense in which neutrinos have wave characteristics is precisely the two-slit sense. (For examples, http://en.wikipedia.org/wiki/Atom_interferometer .) Furthermore, the distinction between fermion and boson is independent of them having mass. There are massive bosons (the W and Z) and, though none yet discovered, plenty of proposed massless fermions.
So I was wondering if we ever started "broadcasting" neutrinos (assuming we had technology to receive them like radios today) would we have a way to divide up the spectrum or otherwise prevent interference? Anyone know? Anyone want to guess?
The precision which neutrino pulses could be detected in time (phase modulation) would determine the signal-to-noise ratio. The bandwidth of the channel is dependent upon that.
So very large, very short bursts of neutrinos at controllable times in very fast succession would be a very high-bandwidth channel. Divide up the spectrum exactly as we do today with radio.
