LiFi is the abbreviation of Light Fidelite, a new type of wireless network connection technology that uses wireless data to transmit wireless data.
It is understood that LiFi sends Internet data through LED bulbs instead of the familiar WiFi radio waves!
The LED bulb generates a very fast optical frequency by transmitting high-speed flicker. The transmission speed per second reaches 200G, which is at least 100 times faster than the WiFi speed. At the Global Mobile Show, OLED comm demonstrated the li-fi technology by first placing the smartphone on an LED bulb and then downloading the video from the Internet. This smartphone is in the absence of any WiFi router with this LED bulb. Have a wireless connection!
Recently, PureLi-Fi has demonstrated a LiFi product that will not only stay in the design and theory.
PureLi-Fi's product is a U-shaped adapter with a light signal and infrared lens mount, and LiFi-compatible LED lights and transmitters above the stand. In the demonstration, LiFi has a transmission rate of 40 Mbps, and it has a strong stability under direct light conditions, and it will fall at the edge of the light, and the light will be diffracted, so that it can be connected while walking around.
Advantages of LiFi: 1. In the Li-Fi environment, the total capacity of the data will be improved, and the light can't pass through the wall. Therefore, compared with Wi-Fi, the network created by Li-Fi will have Safer and more efficient. 2. Li-Fi will not cause interference to other wireless devices. For example, in hospitals, WiFi may interfere with the use of medical devices, but Li-Fi does not.
The disadvantage of LiFi is that the signal is susceptible to interference, and if the source is weakened or blocked, the LiFi signal will be disturbed. Although there are still many limitations in this technology, it is believed that in the near future, technology will be more mature and provide us with a safer and more efficient online environment.
