Visible light positioning – the ‘indoor GPS’ of the future!


In this talk we will show how visible light positioning (VLP) using lighting LEDs can become the all-purpose indoor positioning system of the future. We will show how our patented QADA-Plus system can estimate your position within a few centimetres and is also small enough to be incorporated within future mobile phones.

GPS has become an invaluable and ubiquitous aspect of daily life. But GPS doesn’t work reliably indoors and despite decades of research on RF wireless solutions no ideal indoor system has emerged. The widespread introduction of LED lighting means that VLP is possible. LEDs unlike conventional lighting can transmit high data rate information because they can be modulated at high frequencies.  In the last few years many VLP systems have been described using either photodiodes or cameras as receivers. Our new hybrid receiver incorporates both photodiodes and a camera and so combines the data rates of photodiodes with the accuracy of a camera.

Professor Jean Armstrong Professor Jean Armstrong


Professor Jean Armstrong is a professor at Monash University, Melbourne, Victoria, Australia, where she leads a research group working on topics including visible light communications (VLC), radio frequency communications, and visible light positioning (VLP). She has published many highly cited papers, particularly on OFDM, VLC, and VLP, and her inventions have led to many commercialized patents.

Before emigrating to Australia, she was a design engineer at Hewlett-Packard Ltd, Scotland. In Australia she has held a range of positions at Monash University, the University of Melbourne, and La Trobe University

During her career, she has received numerous awards including a Carolyn Haslett Memorial Scholarship, a Zonta Amelia Earhart Fellowship, the Peter Doherty prize for the best commercialization opportunity in Australia, induction into the Victorian Honour Roll of Women, the 2014 IEEE Communications Society Best Tutorial Paper Award, and the 2016 IET Mountbatten Medal. She is a Fellow of the IEEE and IEAust. She has served on the Australian Research Council (ARC) College of Experts and the ARC Research Evaluation Committee.
