This discussion looks at the current and potential uses of communications technologies and what the implications may be for today and tomorrow. From the invention of the telegraph in 1837 to modern day digital cell phones and GPS navigation systems, communication technologies have come a long way in a short time. Communication devices now serve a broad range of uses, from controlling satellites more than a billion miles from Earth to communicating with tiny networks of devices inside the human body.
