           Shenzhen Risen OPTO Co.,Ltd,led RGB light supplier in china,LED RGB FLOOD Light with 24VAC Input Voltage,led lamp fixtures supplier.According to Tencent Digital reported that people on speed requirements, not the fastest, only faster. Li-Fi, a widely used as an alternative to WiFi technology, now finally from laboratory to the real world. Estonian company called Velmenni venture companies have developed such a fast network transmission technology, has been tested in offices and industrial environments. This new technology and how fast? Velmenni said, Li-Fi speed will be 100 times the WiFi.

          What does this mean? If you follow this rate to measure, to download a high-definition movie takes only a few seconds, probably faster than we now see in the video online movie site speed.

           Velmenni used in the test Li-Fi technology to send data to the fastest 1GBps, and this speed is more than 100 times a WiFi network. In fact, Li-Fi is a wireless technology similar to WiFi, but it is by means of indoor visible light communication (VLC), at a very quick speed to transmit data. Li-Fi technology was invented by Professor Harald Haas University of Edinburgh, compared to WiFi, it has a number of competitive advantages.

           First of all, it is more secure. Li-Fi can have higher security in the local transport network, and since the light can not penetrate walls, so this means between different devices "interference" relatively small. In addition, Li-Fi greatest competitive advantage is probably its data transfer speed. Researchers measured in a laboratory environment of Li-Fi transmission can be achieved 1GBps.

          "We are different from the industrial environment do some experimental tests in these environments, we can use visible light communication technology." Velmenni company CEO Deepak Solanki said, "Currently, we have for those who need light for data transmission in industrial environments devised an intelligent optical solutions. We are also working with private customers to test the technology, we have built a Li-Fi network for them to access their office internet. "

           Nevertheless, Li-Fi may not completely substituted in the short term WiFi technology, these two technologies may exist, thereby creating a more efficient network. If the test is successful, Li-Fi network in the next 3 - to the mass consumer market in five years, so that ordinary consumers to use their household light bulbs to access the Internet.

           Li-Fi before large-scale application of this technology requires further improvement, it can be compatible with existing equipment. "Li-Fi creation of a new infrastructure is very difficult, we need our system to integrate with existing systems." Solanki representation. Li-Fi technology inventor Harald Haas said, the future of each LED bulb light can act as a WiFi alternatives. In TED speech, Haas said the current infrastructure suitable for Li-Fi to do integration.

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