The world's first wireless telephone conversation occurred in 1880, when Alexander Graham Bell and Charles Sumner Tainter invented the photophone, a telephone that conducted audio conversations wirelessly over modulated light beams. In those days, when utilities did not yet exist to provide electricity, there were no practical applications for their invention. Therefore, the wireless technology of Bell’s imagination would simply have to wait until the world was ready for it [and you thought wireless technology was a modern-day invention].
Wireless communication now encompasses a series of other technology apart from the wireless telegraphy. It now also means cellular phone networks and also wireless broadband telephony and internet. Other practical uses are in security systems, where the access can be controlled through wireless technologies. Even the simplest TV or music system remote control devices use wireless technology.
