Wireless communication was first seen when Alexander Graham Bell and Charles Sumner Tainter invented and patented their invention. This was known as the photo phone and was the early persecutor to the telephone. However at that point in time, it didn’t have any use, since electricity or other utilities didn’t exist. When Heinrich Hertz demonstrated the ability of the electromagnetic waves, which were till then a theory, it became significant development in wireless communication. He demonstrated that the electromagnetic waves could be transmitted and can travel in space in straight lines and can be caught by the receiver at the other end.
However it was Jagdish Chandra Bose, who developed the early wireless detection device and branded the spectrum for the knowledge of the wireless communication and the electromagnetic waves. Later on practical uses were found by inventors such as Nikola Tesla for making the wireless radio communication and radio remote control technology.
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 the wireless technology.
