John O'Sullivan
Biography
The efforts of John O’Sullivan, David Skellern, and Terence Percival in developing and commercializing high-speed Wi-Fi provided the milestone technology for practically all in-home and local area mobile Internet communications. O’Sullivan initiated and led the early efforts in techniques for very high-speed wireless networks at Australia’s Commonwealth Scientific and Industrial Research Organization (CSIRO). Percival took over and led the CSIRO project that modeled and prototyped the high-speed modulation schemes and hardware needed for successful Wi-Fi communications. Working in conjunction with CSIRO, Skellern led a pioneering project on wireless local area networks at Macquarie University and in 1997 co-founded, with Percival and Neil Weste, Radiata Communications to commercialize the CSIRO-Macquarie research. O’Sullivan joined Radiata in 1999. In 2000 Radiata demonstrated the first working Wi-Fi system based on the IEEE 802.11a 5-GHz standard.
An IEEE Senior member, O’Sullivan is a physicist and electrical engineer (retired).
