In the fall of 2000, Dr. Joseph Weber of Weber bar gravity wave detector fame delivered a presentation before an international group of satellite engineers in the Reiger auditorium of the former Comsat laboratories in Clarksburg, MD.
He told us that he had developed an ultra-sensitive neutrino detector that was basically a large (palm sized) crystal of pure silicon set inside of a NMR (nuclear magnetic resonance) imaging device. He said that the effect of the nearly perfect silicon lattice was to make the cross section susceptible to neutrino detection larger, and that if a neutrino should strike a single atom in the silicon crystal lattice, they would all vibrate in a manner that he could detect with the NMR setup. So, according to Joe, it was relatively easy for him to detect neutrinos, and all we needed to do was to come up with a way to modulate a beam of neutrinos, and satellite telecommunications would become obsolete overnight.
I told a neutrino physicist (a former assistant to Nobel Laureate Ray Davis) about Joe's ideas about neutrino detection. Jack told me that the idea was not original with Joe, and that it did not work. Furthermore, Joe's Weber bars never detected a single confirmed instance of gravity wave either. Neither has LIGO as yet, so there's no shame or blame here.
Be that as it may, the various methods for producing a beam of unmodulated neutrinos, even from facilities like CERN's LHC are pretty much ad hoc and slap dash (literally), from the descriptions I have read. Communication is really not their specialty nor the reason for constructing their facility. Neutrino communication on the order that Joe Weber envisioned will likely remain something that is in the realm of science fiction until we learn more about how better to produce and detect them.
