( Reading] Wifi and the huge demand for a large amount of data transmission for the current technology have very high requirements. With the development trend of the exponential of a mobile device, by 2019 more than 10 billion mobile devices will exchange 350 billion each month ( 10 ^ 18) Bits of information. 。 。
the huge demand for wifi and a large amount of data transmission for the current technology have very high requirements. With the development trend of the exponential of a mobile device, by 2019 more than 10 billion mobile devices will exchange 350 billion each month ( 10 ^ 18) Bit of information, and this is just the data on mobile. Through conventional computers, big data services and the influence factors of iot equipment and so on, you will find that the seriousness of the problem.
but scientists have discovered a data 100 times faster than traditional Wifi transmission method, and you need to do is turn on the light.
LiFi optical communication is a kind of visible: the LED to the human eye cannot detect flicker, the speed at which to transfer data & ndash; — It's a bit like high-tech Morse code. In fact, scientists have demonstrated in the laboratory, indicates that in this way can realize the 224 billion per second of information, this is equivalent to 18 1. 5 g film. In an office environment, the information transmission speed can reach 100 times of the traditional Wifi speed.
the energy needed to power a LED lamp is very small, it can be power supply through Ethernet power cord. The inventor of this technology Harald Haas also suggests that this kind of intelligent light source can use solar rechargeable battery for power supply. In addition, LiFi doesn't create the same electromagnetic interference and Wifi, which means it can be applied to a lot of very sensitive environment, such as medical institutions.
LiFi sensor & ndash; — To transmit data through the bulb
of course, this approach also has some disadvantages. In a sunny day, the receiver will not be able to distinguish between signal; Unlike Wifi, LiFi signal can't through the wall. Of course, with the development of technology can overcome these limitations, such as design, intelligent buildings that light can follow the user moves in space. Algorithm will be increasingly decide our light and access to data.
in fact, due to the LiFi does not travel through walls, so as to make the real-time data flow more security; Users can access data must appear in the corresponding environment.
in addition, LiFi can be installed in any user like where lights and data services: bus shelters, train station, street lamps, tourist information booth, these places can provide data transmission services.
as the growth of the Internet equipment market, sensors can be deployed to more and more equipment and place, the more rapid and massive data transmission becomes more important. If things continue to predict the rate of growth at present, so our current infrastructure will not be able to process such data transmission requirements.
if we want to continued development of big data and the Internet of things, then LiFi is currently the only viable solution.
the current leds will only need to add a tiny microchips can become LiFi transmitter, in the end, more than 14 billion of the world's light bulbs will be 14 billion transmitter.
pureLiFi company has launched a plug-and-play LiFi system, can transmit 11 per second. 5 MB of data, equal to the first generation of Wifi transmission capacity. Other projects are office building and hospital in testing the technology all over the world.
as we of the data, the degree of the preference of the Internet and mobile market is growing, we need to find a way to transmit more data more quickly. These technologies and network is closely linked. So I believe that once the LiFi technology ( Or similar technologies) Mature, the market demand will grow rapidly and become the darling of the market.
