History

The founding principles and inventions of wireless technology can be found in the lectures and patent record of the electrical engineer Nikola Tesla and in his 1916 deposition on the history of wireless and radio technology.

Modern usage

In modern usage, the term refers to communication without cables or cords, chiefly using radio frequency and infrared waves. Common uses include the various communications defined by the IrDA and the wireless networking of computers.

Low-powered radio waves, such as those used in networking to transmit data between devices, are often unregulated. High powered transmission sources usually require government licenses to broadcast on a specific wavelength. The wireless platform has historically carried voice and has grown into a large industry, carrying many thousands of broadcasts around the world.
