Did you ever wonder what communication was
             before telephones?

          what communication was in his
                      time.

                cellular phones, but in his time,
                 what do you think they used?

 consisted of messages carried by the

 want to message to, unlike now, we can
 send messages in mere seconds

   radiation tramissions, it creates a magnetic detector
Working from Edison’s discovery, his discovery the radio
   wave detector opens the door to advanced radio
   commmunication, he builds “the Rotating Oscilator” and
   discovers the directive properties of the antenna
The “aerial” antenna is first tested to the radio station in
   Glace bay, this could help on radio communication at
   world war 1
