Get ready for lifi, a technology 100 times faster than wifi. Lifi is upcoming technology which will change the way we access internet. So, in simple terms, we can say that this li fi technology is nothing but light based wi fi technology. Lifi is touted as being nearly 100 times faster than the traditional wifi technology based on transmission of radio waves. Imagine streaming a movie through your tube light or accessing the internet through a street lamp. Imagine a world where every light connects us with unprecedented data and bandwidth. Furthermore, philips points out, li fi can be used in situations that require more security, as light cannot pass through solid walls, and in order for li fi to work, you need to literally see the. Additionally, where there is a lack of light bulbs, there is a lack of lifi internet so lifi does take a hit when it comes to public wi fi networks. And as we know, this wi fi is fully networked, bidirectional wireless communication technology. The existing wi fi systems use radio waves to transfer data.
A lifi enabled device converts the beam of light into an electrical signal. What if we could use existing technologies to provide internet access to the more than 4 billion people living in places where the infrastructure. Lifi could transmit up to 100 gbps and possibly higher, but this would require a change in lighting technology. Take this quiz to find out which it career is right for you. Li fi provides transmission of data through illumination by sending data. If you enjoyed this video about li fi internet technology, why not consider a career in it. Recent news report that lifi is 100 times faster than wifi. The world might eventually have to shift its reliance on wi fi to lifi, an alternative technology that scientists say can reach speeds of 1 gbps in realworld use 100 times faster than.
Not to mention, lifi requires the light bulb is on at all times to provide connectivity, meaning that the lights will need to be on during the day. The technology is very new and was proposed by the german physicist harald haas in 2011. Imagine every light could connect us tot he internet. Li fi idea rates as one of 50 best inventions of 2011 on ted world site on the internet. Although internet users might think that li fi, with its insane speed of 224gbps, is capable of leaving out wi fi for good, its important to understand the li fi. Thus y ou can use internet in running rooms by li fi technology. Of course, this also speaks to the products downsides.
Pure lifi transmits data using light video pure lifis system sends data wirelessly using light rather than radio waves, with a li flame prototype that knows which light source its supposed. Oledcomm shows lifi, 10mbitps internet by light youtube. Connect your bulb to your adslfiber box, and anywhere the light reaches, a receiver can download that data at up to an up to 10mbitps. Here we will do data transmission experiment by using lifi. Transmit music file over the visible light spectrum using lifi visible light communication to a speaker.
