"Spectrum" knows no protocol. All RF signals transmitted through the air are analog by definition. So are all cable RF signals in coax for that matter. Television was using it for television. Your cell phone probably uses some of what was originally channels 70-83, which was reassigned to AMPS back in the early 80's. 800 MHz trunking systems for two way radio work in that ex-TV band too. That is definitely 2-way. -- Toolmaster of La Grange. |
