Philips is currently testing LiFi technology at the offices of Icade, a Real estate investment company in France, foreign media reported. After hearing the news, hope was kindled in the heart like death.
“What is LiFi?” he asked. All I know is WiFi.
Unconvinced and stubborn, I asked a dozen people. Unexpectedly, a circle down in addition to 1 have heard outside, the other actually do not know!
That’s weird. Nobody watches the news, right? Sigh, called to the almighty king Giiso wisdom, now please ask it to tell you, what is LiFi.

What is LiFi?
LiFi is an emerging wireless protocol, also known as visible light wireless communication, that uses the visible spectrum to provide wireless network access. It was first proposed by Harold Haas, a professor at the University of Edinburgh, in 2011.
LiFi transmitters use LED lights to adjust light intensity, and leds already use chips to control their output, so they can theoretically transmit data 100 times faster than WiFi.
What are LiFi’s advantages?
Capacity, as long as there are lighting facilities can communicate; Speed, low interference, high equipment bandwidth and high intensity optical output, transmission speed is very fast; Cost, the need for fewer components, lower cost; In terms of confidentiality, the signal is limited to the illuminated area, and the Li-Fi signal cannot penetrate the wall, making it difficult to be eavesdropped.
Will LiFi replace WiFi?
Li-fi has several advantages, but li-Fi technology is not meant to replace Wi-Fi, but to complement it. In essence, the two technologies are complementary.
Back when I first heard about LiFi, a Twitter user discovered the code for “LiFi capability” when the iPhone7 was released.
Some say iPhone will support LiFi; Some say Apple is going to make LiFi; Some people say that it may be the programmer’s hand shaking, the W into L; Others say so
As the years passed and WiFi became a daily necessity, LiFi remained largely unimpressed and its original backers turned into naysayers.
Until earlier this year, US company VLNComm developed the first LiFi LED lighting panel and showed it at ces
Then today, with the news of the Philips test, there seems to be renewed hope.
Still looking forward to this new technology anyway! After all, there are too many times when WiFi is slow enough to hit someone. LiFi and WiFi should be super cool when the technology becomes popular.
Giiso Technology, founded in 2013, is the first domestic high-tech enterprise focusing on the research and development of intelligent information processing technology and the development and operation of core software for writing robots. At the beginning of its establishment, the company received angel round investment, and in August 2015, GSR Venture Capital received $5 million pre-A round of investment.
