    As noted in a couple comments there is some misinformation presented there.
    That is not correct at all. Radio waves travel at the same speed, regardless the frequency: ~186,000 miles per second, or the speed of light. This is a Law of Physics. And Radio waves, regardless the frequency will travel the same distance (forever!) unless blocked. However different frequencies will behave differently. Some travel in straight lines only (line of sight), some bounce off objects or the atmosphere.

    However, higher frequencies, as with CPUs, means more information can be processed in the same amount of time. So in terms of data "bandwidth" higher frequencies can support more. This results in "faster" data transfer but not faster radio waves or signals.

    It will be interesting to see what the FCC allows as the government owns the frequencies and allocates when, how and who will use it.
