Connected Nation - Pitch: Ultra Parallel Visible Light Communications - Martin Dawson, University of Strathclyde

Supplementary content information

Can you communicate through a light-bulb? Breakthrough wireless communications systems using micro-LEDs could massively increase the available bandwidth for communications, opening up a new spectrum of possibilities, and create additional benefits such as increased security and energy savings.

I’m Martin Dawson from the University of Strathclyde. I’m here today to describe our work under a project called Ultra Parallel Visible Light Communications (UPVLC); data communications through a light. One of the things that's happening at the moment which Colin Humphreys will describe, I’m sure, in his presentation is the excitement around the replacement of traditional incandescent and fluorescent lighting by solid-state LED based lighting. A key recognition associated with this sort of lighting is that is semiconductor based, and semiconductor-based technologies interface very well with electronics. So in fact that the lighting itself in our rooms, in our offices and so on is in the process of becoming digital.

One aspect of that digital lighting is the ability to be able to communicate through lighting. And that's what this project is about. It’s a partnership between five universities; Strathclyde, Oxford, Cambridge, Edinburgh and St. Andrews looking at micro-pixel light emitting diode technology as a very high bandwidth optical wireless communications capability; looking at spatial multiplexing wavelength division colour control in these lights and the ability for example to project real-time video directly from your lighting infrastructure in your building. It can also track movement to allow you to have service free operation of this technology as you move around in space. So we’re looking forward to showing you our technology at the stand, and we're very excited about it, excited to be here today. Thank you.
