Needless to say, the use of wireless communications has increased exponentially since that breakthrough. The discovery of electromagnetic waves by the German physicist Heinrich Hertz in 1887 is generally considered to be the take-off date for wireless communication. This is understandable, because all kinds of wireless communication nowadays work with Hertzian waves, wireless telephony, radio, live television, or wireless computing in its various technical appearances, e.g. Bluetooth or the wireless local area networks (WLAN or “WiFi”). The textbook version of the history of “the wireless” usually continues with the Italian engineer and businessman Guglielmo Marconi, who introduced wireless telegraphy in large scale in the British Empire and who was the first to transmit wireless signals across the Atlantic Ocean.
