Incredible! Use LED Smart Bulbs to Access the Internet Or Serve As Routers

Now every time you reach a place, the first sentence is not to say hello, but a simple and clear question:“Is there Wi-Fi, what is the Wi-Fi password?”Essence For some smart devices, Wi-Fi has become an indispensable thing in our lives. However, sometimes, Wi-Fi is not ubiquitous. For example, in the basement or a more complicated room, the Wi-Fi signal may not be fully covered. A few days ago, the R & D team of the Department of Electronics and Computer Engineering at the University of Virginia is conducting experimental projects that send wireless signals through LED bulbs—Lifi. If the final experiment is successful, you can serve as a router through the LED bulbs that can be distributed wirelessly at home, so that the wireless signal in the home can be everywhere. Maite Brandt Pearce, the person in charge of the R & D team, said:“Sending wireless data through LED bulbs does not use more energy, and the LED bulbs are just expanding the auxiliary means of expanding the wireless signal through their ubiquitous lights. Wireless Router.”Lifi is enhanced by wireless data signals through LED bulbs, which can make Wi-Fi ubiquitous. Of course, the first premise is to ensure that there is no transparent window in the entire room, otherwise the Wi-Fi signal is likely to be damaged by the bulb transmission. Earlier, a company named Vlncomm had applied for relevant patents and used LIFI technology to connect to the Internet through the light waves of the desk lamp. In addition to enhancing wireless signals, LIFI is that the bigger advantage is that it is extremely simple to implement. The replacement of LED bulbs is very convenient. Another major advantage of LIFI is that there are no restrictions on the light waves such as the unrequited and popular places such as the hospital. R & D personnel said:“This technology will have an impact on the Internet of Things. For example, alarm clock can communicate with the coffee pot, notifying that the coffee pot can start coffee. In other words, device equipped with LED bulbs can communicate with each other. Of course, you don't need to be equipped with a wireless signal transmission device alone, because as long as there is LIFI, it is enough.”
