John Visser earned a Bachelor of Applied Science in Electrical Engineering from the University of British Columbia in Vancouver, Canada in 1973. After gaining practical experience in diverse areas within military communications as an officer in the Canadian Armed Forces, John joined Bell-Northern Research, then the R&D arm of Nortel Networks, in 1978. Since then, he has been involved in many key network standards, systems engineering, planning, product design, and product line management support activities. He has an extensive background in SS7, ISDN, Intelligent Networks and mobile networks, and has held a series of positions of increasing responsibility, both internally and within standards bodies, in these areas over his career with Nortel Networks. John became an independent consultant in March 2009. Together with prior activities in ANSI T1, TIA, and other areas in ITU-T, and the 3G Partnership Projects, John is very active in International Mobile Telecommunications (IMT 2000) standardization work in ITU-T. In October 2000, John was appointed Chairman of the ITU-T Special Study Group (SSG) on "IMT 2000 and Beyond". In October 2004, he was appointed Chairman of the successor to ITU-T Special Study Group SG 19 “Mobile Telecommunication Networks”. The SSG/SG 19 has been successfully globalizing the 3GPP and 3GPP2 specifications as adopted by their partner organizations, and progressing the vision and requirements for the core network infrastructure of next generation mobile systems. The latter includes inter-system mobility management, and the convergence of fixed and mobile networks. At WTSA-2008, John was appointed Chairman of TSAG. John is a member of the Advisory Board of the Advanced Software Engineering Research and Training (ASERT) Laboratories at the University of Ottawa and Carleton University. He is also a guest lecturer at Carleton University and a frequent speaker at conferences and seminars. John is a Registered Professional Engineer in the province of Ontario and a member of IEEE.
