Meh. You can have 1,000 wires in a bit of pipe, effectively 1,000 "spectrums." The air will always only be a single spectrum. Cell division does not scale in

Meh. You can have 1,000 wires in a bit of pipe, effectively 1,000 "spectrums." The air will always only be a single spectrum. Cell division does not scale infinitely, and becomes more and more complex to manage. Running cable you do once, then you can benefit for a long time. Wired will always be the better technical solution, and more economic one, in built up areas.
