It is understood that LiFi sends Internet data through LED bulbs instead of the familiar WiFi radio waves!
Led bulbs are generated by high-speed flicker to produce an extremely fast optical frequency. The transmission speed per second reaches 200G, which is at least 100 times faster than WiFi. On the global mobile exhibition, Oledcomm company demonstrated li-fi technology, the first smart phone on taking a dip led lights illuminated, then download video from the Internet, this smart phone with the LED light bulb without any WiFi router case Have a wireless connection!
Recently, Pure Li-Fi has demonstrated a LiFi product that will not only stay in the design and theory.
Pure Li-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. If the light 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.

Traditional 60-cell and 72-cell solar panels will have 120 half-cut cells and 144 half-cut cells, respectively. When solar cells are halved, their current is also halved, so resistive losses are lowered and the solar cells can produce more power.
Smaller cells experience reduced mechanical stresses, reaching a decreased opportunity for cracking. Half cut cell PV modules have higher output ratings and are more reliable than conventional solar panels.
