Imagine if the LED bulbs in your house could transmit high-speed data without WiFi or broadband. Or an LED-lit movie billboard that can relay high-quality promotional videos and songs to your smartphone as you pass by in a crowded mall? Well, these scenarios are not out of any sci-fi thriller — the government of India is already testing technology that can enable this and other features.
In a recent pilot project, the ministry of electronics and IT successfully tested a technology called LiFi (Light Fidelity), which uses LED bulbs and light spectrum to transmit data at speeds as high as 10 GB per second over a 1-km radius.
The pilot project was conducted in association with Indian Institute of Technology Madras at its campus along with lighting company Philips a few months ago. While the pilot was staged in a closed environment, ERNET now plans to test it in open spaces in partnership with Indian Institute of Science, Bengaluru.
