“Technique puts more data into airwaves” "phony science"? tfrugal, first, 3 things. 1. I am long QCOM, 2. I have not read the original article, just your post from it, and 3. I said that if this information had not come from a respected source (Bell Labs) I wouldn't give it any credibility. Perhaps the science involved lost something in the translation to language intended for readers without a strong scientific education. Here are my concerns. Saying that ordinarily the red, green, and blue components of a color picture would require separate transmission channels is nonsense. Perhaps they meant that 3 colors require more bandwidth than a single color in order to be sent in the same period of time. One of the scientists says that multi-path scattering "adds an extra information-carrying dimension to those waves." How is that possible? How could disturbances in the path between sender and receiver make it possible to add information at the sender? Wouldn't an undisturbed path be the best possible case? The same scientist also says "textbook explanations of electromagnetic waves preclude polarization along the same direction a wave travels." I choose to believe the textbook on this. Disclaimer: I am an electronics engineer, not an expert in math or propagation (or in electronics for that matter).
