Nearly a billion people use John O’Sullivan’s invention every day. When you use a WiFi network - on your mobile phone, at home, in the office or at the airport - you are using patented technology born of the work of John and his CSIRO colleagues.
John O’Sullivan is an Australian electrical engineer whose work in the application of Fourier transforms to radio astronomy led to his invention with colleagues of a core technology that made wireless LAN fast and reliable. This technology was patented by CSIRO and forms part of the 802.11a, 802.11g and 802.11n Wi-Fi standards.
