Imagine just switching on your lights and downloading a movie in a second. The world demands high-speed internet connectivity at a lower price. This increasing clamour for speed and bandwidth is opening up new avenues, and one such evolving domain is LiFi - a wireless technology that makes use of light-emitting diodes (LEDs) to transmit data. Light waves are 10,000 times denser than WiFi signals, so there is vast untapped potential here.
