    its a strange yet cool feeling when youre watching this vid on your phone and you pan out a bit to admire the awesomeness of the thing youre holding now

  • Scott Provost говорит:

    The Bay Area Police Emergency Radio Network was the first cellular network. Cellular radio communications networks were not legal yet but the fact that it was only supposed to be used for emergencies made breaking the FCC Rules temporarily lawful. But that legality was questionable so the Motorola COMSS and maintenance staff never discussed the legality.
    Motorola employees did not retain intellectual property rights and the legality concerns kept everyone quiet hence the truth about who invented cellular communications.

    Your videos are first class. At this moment you have 7189 likes and 86 dislikes. I wonder what it was that those 86 didn't like. You can't please everyone I know but I still wonder. Love your videos.
