Centre switches on superfast Internet pilot – Li-Fi in India

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.

Lucibel brings Li-Fi Internet connectivity to French hospital

Lighting systems manufacturer Lucibel announced that it has completed its first deployment of ‘LiFi by Lucibel’ in a hospital environment, installing the service in the cardiology department of the Stell clinic in the town of Rueil-Malmaison (Ile de France region). The company said that Li-Fi Internet connectivity is particularly suited to areas within hospitals where the use of Wi-Fi is not recommended or forbidden, due to the risk of interference with medical equipment. The service also offers the additional benefit of providing hospital staff with a secure connection to access patient data.

What is Li-Fi Internet

Light Fidelity (Li-Fi ) is a bidirectional, high speed and fully networked wireless communication technology similar to Wi-Fi. The term was coined by Harald Haas  and is a form of visible light communication and a subset of optical wireless communications (OWC) and could be a complement to RF communication (Wi-Fi or Cellular network), or even a replacement in contexts of data broadcasting. It is so far measured to be about 100 times faster than some Wi-Fi implementations, reaching speeds of 224 gigabits per second.

It is wireless and uses visible light communication or infra-red and near ultraviolet (instead of radio frequency waves) spectrum, part of optical wireless communications technology, which carries much more information, and has been proposed as a solution to the RF-bandwidth limitations.
