Previously, it was revealed on the Internet that oppo brand plans to put lifi technology into mobile phones. Recently, the rendering image of oppo mobile phone equipped with this technology is exposed. The machine adopts a full screen design, and the rear camera is arranged vertically. Of course, the biggest highlight of this mobile phone is the introduction of lifi technology. < / P > < p > as can be seen from the pictures on the Internet, oppo plans to install the lifi led transmitting lights in the top and back areas of the mobile phone, so as to facilitate the transmission and reception of signals. However, some netizens said that the design of lifi LED light on the top or back of the mobile phone may affect the installation of protective case for the mobile phone, and they do not like this design very much. What do you think of this? It is understood that lifi technology is a faster WLAN technology than WiFi technology, and theoretically the former is hundreds of times faster than the latter. However, this technology also has a fatal disadvantage, if there is no light, the signal can not be transmitted or transmission capacity is poor. In addition, the transmission distance of lifi technology is only about 10 meters, while WiFi technology can reach about 32 meters.
