Monday 25th Jul 2016, 02.15pm

This podcast is part of the The Big Questions series.

Can we receive information through our lighting?
 
Prof Dominic O'Brien explains how light might be the answer to adding more capacity to our wireless internet connections. You might be used to connecting to the internet through a wireless network that works through radiowaves, but what if we could use lights in buildings to send information; like data from the internet? Using LEDs for something more novel than just christmas decorations, Dominic is looking to find ways around the challenges of sending information, in a way that can be used for sending information with light, at high enough 'speeds' to complement WiFi.
