If you are still using WiFi, you will be out: li-fi is better!!!

You know, WIFI, But you know LI-FI Do you ？LI-FI Have you never heard of ？ No hurry .LI-FI It's a ratio. WIFI Better new technology .LI-FI（Light Fidelity） It's a new technology , go by the name of “ New wireless network connection technology ”, Its main function is to use the visible spectrum to realize wireless data transmission . This technology was first Harold Hass Professor Yu 2011 In a speech in .

In Barcelona, Spain this year MWC Mobile world congress ,PureLi-Fi The company showed us Li-Fi Actual products , So what is it with Wi-Fi What's the difference ？ Let's get to know .
PureLi-Fi The company's network chief operating officer Harald Burchardt In an interview with the media, he said ：“Li-Fi It's very simple , We go through LED Light to transmit wireless signals , It's a bit like Wi-Fi, But what we're using is LED Lights and other lighting media to complete wireless data communication .”
according to the understanding of ,Harold Hass Professor from 2003 Began to study this Li-Fi technology , Because he foresaw the upcoming spectrum crisis . About the same time , new LED Light source technology began to impact the market , therefore Harold Hass The professor came up with the idea of combining them . Final , He found a way to use these electronic lighting components to achieve high-speed data transmission , At the same time, it will not cause interference to the existing radio frequency infrastructure .
Founded on 2012 Year of PureLi-Fi The main purpose of the company is to Li-Fi Commercialization of Technology . The actual product they showed is a U Disk shaped adapter , It is equipped with a light and infrared lens type receiving device for receiving light signals . besides , The upper part of the booth is also equipped with a compatible device for transmitting wireless data Li-Fi Of LED Lights and transmitters .

The data transmission speed of this product has reached 40Mbps, And it can achieve very strong stability in the case of direct light , The edge of the light will drop , Thanks to the reflection of light , There is no problem with the device connection , Walking back and forth does not affect the use .
Harald Burchardt Pointed out that , the Li-Fi Technology has two key advantages , It can transmit more data in a local area , At the same time, the security is also higher . He explained that the ：“ stay Li-Fi Environment , The total capacity of data will be increased , Plus, light can't pass through the wall , therefore , Follow Wi-Fi By comparison , The network we create will have higher security .”
in addition ,Harald Burchardt Also said ：“ As this technology matures , We hope that the ideal situation is to reduce the volume of this product , Build it into an integrated circuit module , And then used in smart phones 、 The tablet 、 laptop 、 Wearable devices and other types of electronic devices .”
however ,Harald Burchardt Finally, I also admit , Although this technology will be very promising , At that time, it still needs 10 To 15 It takes years to appear in every LED Lights or every electronic device , and PureLi-Fi What the company needs to do is to achieve this goal in a relatively short time .
