Philips, Dutch technology major announced on March 19, 2018, that they are utilizing Light Fidelity (LiFi) technology in French offices
Light Fidelity (Li-Fi) is a wireless optical networking technology that uses light-emitting diodes (LEDs) for data transmission. The technology is designed to use LED light bulbs, which are similar to the one used at homes and offices for low energy consumption. LiFi provides broadband internet through lights, using LEDs to transmit a high-speed connection up to 30 Mb per second through light waves. It works through LED luminaires that are equipped with built-in modems. To use this technology, users need to plug a USB dongle into their computers to access LiFi, the tech will eventually be built into other devices in near future. The dongle uses an infrared link to access LiFi, which is purported to be more secure and more reliable than WiFi.
Philips Lighting is renowned for its bulbs and other illuminating fixtures. The company intends to enter in internet space segment by offering Light Fidelity. Li-Fi has potential application in areas where Wi-Fi connectivity is weak. For instance, while radio frequencies may not be able to reach areas underground or interfere with equipment, lighting can be placed anywhere. Furthermore, Philips points out, Li-Fi can be used in situations that require more security, as light cannot pass through solid walls.
“LiFi has enormous potential for today’s digital age and as the world’s leading lighting company we are proud to pioneer new and innovative services for our customers,” said Olivia Qiu, chief innovation officer at Philips Lighting. “While radio frequencies are becoming congested, the visible light spectrum is an untapped resource with a large bandwidth suitable for the stable simultaneous connection of a vast array of Internet of Things devices. Being a lighting company, we ensure that our customers benefit from the finest quality energy efficient light along with state-of-the-art connectivity.”
