The History of the WiFi

The history of WiFi goes back to 1970's in the Hawaiian Islands with a UHF wireless packet network. Which was the first demonstration of wireless packet data network. This network was very simple and was not what we know today. Vic Haynes was the first one to do work on developing WiFi. "Vic Hayes is often regarded as the “father of Wi-Fi.” He started such work in 1974 when he joined NCR Corp., now part of semiconductor components maker Agere Systems. A 1985 ruling by the U.S. Federal Communications Commission released the ISM band for unlicensed use – these are frequencies in the 2.4GHz band. These frequency bands are the same ones used by equipment such as microwave ovens and are subject to interference."(purple.ai) The creator of the WiFi we know today including its protocols for how it would be transfered via radio waves is accredited to "The Australian radio-astronomer John O’Sullivan with his colleagues Terence Percival, Graham Daniels, Diet Ostry, John Deane developed a key patent used in Wi-Fi as a by-product of a Commonwealth Scientific and Industrial Research Organisation (CSIRO) research project, “a failed experiment to detect exploding mini black holes the size of an atomic particle”. In 1992 and 1996, CSIRO obtained patents for a method later used in Wi-Fi to “unsmear” the signal. "(cablefree.net) As technology has improved the speeds achieved have also increased. The latest prtocol is 801.11ac. It is focused on making the 5Ghz range better. Overall the devolpments of WiFi have come a long way since when it was originally created in the 1970s.
