Alexander's assistant succeeded in transmitting a wireless voice telephone message to a significant distance of around 700 ft (213 meters). This occurred on June 21, 1880, 19 years prior to the first voice radio broadcast. The voice message was transferred from the roof of the Franklin School to the window of Bell’s laboratory.
