VIC HAYES, JOHN O’SULLIVAN, 1997

Wi-Fi, or 802.11 networks, is a technology that allows a device to exchange data using radio waves, just like cellphones and radio’s do. A Wi-Fi network – short for Wireless Fidelity – is relatively cheap and easy to set up. Devices that use Wi-Fi can connect to a network via a wireless network access point, also called “hot spots”. One of the key technologies behind Wi-Fi was developed by radio astronomer John O’Sullivan as a by-product in a research project to detect mini black-holes. That sounds rather cool, doesn’t it? Vic Hayes has been called the “father of Wi-Fi”, he chaired the IEEE committee that created the 802.11 network in 1997.
