Imagine a future where every one of the billions of light bulbs in use today is a wireless hotspot delivering connectivity at speeds that can only be dreamed of with Wi-Fi. That's the goal of the man who invented such a technology, and this week Li-Fi took a step out of the domain of science fiction and into the realm of the real when it was shown to deliver speeds 100 times faster than current Wi-Fi technology in actual tests. Lifi internet is similar to Wi-fi. It is a wireless, bidirectional technology founded by Professor Harald Haas of University of Edinburgh. Li-fi stands for Light fidelity which takes light from light-emitting diodes (LEDs) as a path to deliver networked, mobile, high-speed communication. Lifi is a wireless technology using LED lights to transmit data through network. Scientists have receive a speed of 224 gigabits per second in laboratories by using this technology and the expected speed in the in the outside world could be 1giga-byte (1GB) per seco...
