Dr Kegen Yu received a BEng degree from Jilin University, China, a MEng degree from the Australian National University, Australia, and a PhD degree from the University of Sydney, Australia, in 1983, 1999 and 2003 respectively. From 1983 to 1997 he worked as a practicing engineer and later a lecturer at Nanchang University, China. From 2003 to 2005 he was employed as a Postdoctoral Fellow at the Centre for Wireless Communications, University of Oulu, Finland, researching on wireless positioning and communications theory. Since November 2005 he has served as a Research Scientist at CSIRO working on ad hoc wireless positioning systems, wireless sensor networks and reconfigurable radio. Kegen has published three book chapters, and over 40 refereed journal and conference papers.

Ian Sharp is a Senior Consultant on wireless positioning systems. He has over 30 years of engineering experience in radio systems. His initial involvement in positioning technology was in aviation and later, in the 1980s, with the Interscan microwave landing system (MLS). In the later 1980s to the early 1990s, Ian was the R&D manager for the Quiktrak covert vehicle tracking system. This system is now commercially operating worldwide. From the mid 1990s to 2007 Ian worked at the CSIROmainly on developing experimental radio systems. Hewas the inventor and architect designer of CSIRO's precision location system (PLS) for sports applications. The PLS has been successfully trialed in Australia and the USA. Ian holds a number of patents relating to positioning technology.
