100 times faster than Wi-Fi, this Indian company wants to popularize "Li-Fi" technology...
The requirements of human speed on the Internet are not as fast as they are faster. Wi-Fi has become the demand for Maslow's demand that is lower than that of physiology. Although Wi-Fi is now everywhere, there are many unsatisfactory scenarios, such as In most cases, the speed of the Internet is still very impressive. . .
Is there no faster network connection than Wi-Fi? At the site of the Asian Intelligent Hardware Contest hosted by Mobile Technology, the titanium geeks saw Velmenni from New Delhi, India. The company's R&D products are based on Li-Fi. (Wi-Fi's relatives...)
Judging from available information, Li-Fi is also known as light fidelity. It is a new type of wireless network connection technology. It is mainly through the visible light spectrum to achieve wireless data transmission and belongs to visible light communication. One of technology.
The name Li-Fi was first publicly presented by Professor Harald Haas of the University of Edinburgh in the United States in October 2011 at the TED Global conference.
If divided according to the coverage scenario, Li-Fi is more of a supplement rather than a substitute for Wi-Fi, Bluetooth, NFC, and other transmission methods. One of the advantages of this technology is that its visible light spectrum is 10,000 times larger than the radio frequency spectrum, which means more bandwidth and higher speed, and it is less likely to interfere with other devices.
In terms of speed, the theoretical limit of Li-Fi is 220Gbps, and the latest WIFI standard is only 1.3Gbps. In terms of security, Li-Fi's data transmission does not need to cross the wall, so it is inherently safer than WIFI.
At the Asian Intelligent Hardware Contest, the founder of Velmenni was also on the scene: "Like we are in such a conference venue today, although we have a Wi-Fi connection, we can't even connect to it. Why? Because connecting people too. That's more, so there will be such congestion."
Velmenni currently has three different products, namely LIFI Transmitter, INTERENT HUB and MESH HETWORKING. Li-Fi can transmit very large data remotely. INTERENT HUB can establish an "Internet center" in its own home and build a Li-Fi transmission center in the store.
In 2014, Velmenni received a seed fund. In March 2015, Velmenni had already used this technology to achieve a transmission speed of 1 Mbps in a range of 10 meters. In November 2015, the Li-Fi technology used in its testing was able to send data at the fastest rate of 1GBps.
The Velmenni team released an advantage analysis chart comparing the competing products at the competition site. Therefore, investors began to question: “Your competitors seem to be three times faster than you. What do you think of your advantage over them? Can you catch up? On their speed?"
The Velmenni team stated, “We are at a speed of 1Mbps per second. This speed is not reachable in many parts of the world. When we transform and commercialize results, we will consider, for example, its limitations in different applications. Sex, such as the particularity of data transmission on an airplane, may need to be adjusted in terms of designing the solution, not just considering speed."
When the light source changes, we also change the rate. We consider that the stability of the light source under different application space application scenarios changes the speed of our data transmission. This has been considered, and there are Some solutions have.
Li-Fi technology is currently mainly used in indoor scenes, including hotels, airports, and train stations, but Velmenni is also doing other experiments in other scenes, such as outdoor scenes. Their first product is tailor-made for "aircraft." It is planned to be launched in the first quarter of next year.
As the most likely alternative to Wi-Fi technology in the future, it is finally necessary to move from the laboratory to the real world.
