You can surf the Internet with lights! LED optical communication Lifi products come out

 In 2011, Harald Haas, a professor at the University of Edinburgh, delivered a speech on Lifi technology on TED. Lifi is a communication technology based on visible light, which transmits data information through the light of LED lights and creates network signals that can be used by various terminals. .

In addition to the University of Edinburgh, the Fraunhofer Institute for Optoelectronics in Germany, the ACEMIND project operated by another European team, and the laboratory of the School of Computer Science and Technology of Fudan University have all realized similar technologies. For now, Edinburgh-based pureLife is the first related startup.

Recently, pureLifi announced that it has received a new round of investment of 15 million pounds (about 141 million yuan), led by London & Scotland Investment Group (LSP), Old College Capital and Scottish Investment Bank (SIB). The chief scientific officer (CSO) of the project is Harald Haas, and the financing will be used to support the product development route, as well as marketing and sales.

The company's first-generation product Li-1st can achieve two-way transmission within three meters, with a speed of up to 5Mbps, while the lighting function of the LED lamp will not be affected in any way. In the fourth quarter of 2014, the pureLife team launched Li-Flame, a LiFi network product. This system can convert existing light bulbs into LiFi access points and automatically transmit data bidirectionally. In other words, as long as you have Li-Flame, you can surf the Internet when you see the light bulb.

 Li-Flame has two key accessories. One is a ceiling kit, which can form a small-scale multi-access switching network by simply connecting to LED lamps through a standard Ethernet port , and seamlessly switch between APs (AccessPoints). The other is the desktop kit, which is connected to the user's device through the USB interface, and then can use infrared rays to upload data to the ceiling kit, and the speed can reach 10Mpbs. The Li-Flame is rechargeable and ensures a constant connection when the user moves from one AP to another (such as entering another room), enhancing user mobility.

As for security issues, since Lifi signals are carried on a very narrow beam of optical channels, it is difficult to pass through walls. At the same time, since the upload and download channels are separated, if a hacker attempts to attack a computer, he must crack the two-way channel in theory. Then the most reliable way to achieve it is to be in the same room as the computer he wants to attack.

Li-Frame is currently on sale, and its main customer base is enterprise users. Before this technology took shape, many commercial visions focused on the construction of public facilities (such as turning street lights into network hotspots) and enterprise network security guarantees. According to the official website, the demand for this product is still high in the first quarter of 2015. After analyzing industry data, Marketandmarkets predicts that the LiFi industry will grow to at least $9 billion (about 55.926 billion yuan) by 2020. Haas said that he is very optimistic about this new technology, because it will promote the shift of the mobile Internet to a cellular network, usher in the 5G era, and at the same time promote the development of the Internet of Things.
