Go Fast With Li-Fi | Rajat Poonia Rajasthan
Li-Fi technology A new technology, known as Li-Fi, could one day offer internet speeds one hundred times faster than the Wi-Fi we use today. Scientists have achieved speeds in the lab of up to 224 GB per second. Like radio waves, visible light is part of the electromagnetic spectrum. The difference is that viable light has a spectrum 10,000 times larger than radio waves. This means Li-Fi has the potential for enormous capacity. Instead of transmitting information via one data stream, visible light would make it possible to transmit the same information using thousands of data streams simultaneously. That’s the equivalent of downloading 18 movies in the blink of an eye. Li-Fi, or light fidelity, is now moving to trials in the real world, with office tests in Tallin, Estonia achieving speeds of 1 GB per second, 100 times the speed of traditional Wi-Fi. Is it end of Wi-Fi? Li-Fi probably won’t bring about the end of Wi-Fi. At least not for the foreseeable future. Though f
