Wifi or not Wifi…
What is Wifi and who invented it?
Wifi is a technology that allows wireless devices such as laptops and mobile phones to access the internet. It is also known as WLAN (Wireless Local Area Network). It is difficult to name a single inventor of Wifi as its development was built on ideas and inventions from many individuals.
– The history of WLAN stretches back more than a century to the work of Guglielmo Marconi, the Italian inventor who began experimenting with radio waves in 1894.
In the 1940s, Hedy Lamarr and George Antheil invented a system that allowed radio waves to jump onto different frequencies. The idea was to stop the US Navy’s radio signals from being intercepted by their enemy in World War 2. This was a vital step in the development of Wi-Fi.
