5 years later, we can use Li-Fi?

According to Tencent digital reports, people on the speed requirements, not the fastest, only faster. Li-Fi, as a widely used alternative to WiFi, is now moving from the laboratory to the real world. Estonia, a start-up company called Velmenni has developed this ultra fast network transmission technology, has been tested in the office and industrial environment. How fast is the new technology, Velmenni said, Li-Fi will be 100 times the speed of WiFi.

What does that mean? It's only a matter of seconds to download a high-definition movie at this rate, perhaps faster than we are now watching online movies on video sites.

The Velmenni technology used in the Li-Fi test can send data at the fastest rate of 1GBps, which is currently more than 100 times the WiFi network. In fact, Li-Fi is a wireless technology similar to WiFi, but with the help of indoor visible light communication (VLC), can be very fast to send data. Li-Fi technology was invented by Professor Harald Haas, University of Edinburgh,, it has a number of competitive advantages.

First, the higher security. Li-Fi can have a higher security in the local network transmission, and because the light can not penetrate the wall, so this means that the interference between different devices is relatively small. In addition, Li-Fi's biggest competitive advantage may be its data transfer speed. Researchers in the laboratory environment measured Li-Fi transmission can reach 1GBps.

"We are doing some experimental testing in different industrial environments in which we can use visible light communication technology. Velmenni CEO Deepak Solanki said, at present, we have designed for those who need light to transmit data in the industrial environment of an intelligent light solutions. We are also working with private customers to test the technology, we set up a Li-Fi network for them to access their office site internet. "

Nevertheless, Li-Fi may not be able to completely replace the WiFi technology in the short term, these two technologies may exist at the same time, thus creating a more effective network. If the test is successful, Li-Fi network will be in the next 3-5 years to the mass consumer market, so that ordinary consumers can use their home bulbs to access the internet.

Prior to the large-scale application of Li-Fi, this technology needs to be further improved to make it compatible with the current device. "Creating a new infrastructure for Li-Fi is very difficult, and we need to integrate our systems with existing systems," he said. "Solanki representation. Li-Fi technology inventor Harald Haas said that the future of each LED bulb can serve as a substitute for WiFi. In the TED speech, Haas said the current infrastructure for Li-Fi integration.

"What we need to do is to add a microchip to each lighting device so that it can have two basic functions: lighting and wireless data transmission," Haas said. In the future, we will not only have 14 billion bulbs, we may also be in a more environmentally friendly way to build a Li-Fi network of 14 billion. "
