一种新兴的Li-Fi可见光无线通信技术浅析

Analysis of a New Li-Fi Visible Light Wireless Communication Technology

目前全球WiFi上网越来越普及,其技术也相对成熟,但WiFi热点上网信号不稳定,特别是接入用户较多时,上网速度明显变慢。近年来,一种新兴的Li-Fi可见光通信技术利用发光的LED灯泡作为"热点"来进行无线通信传输二进制数据,可能在不久的将来解决该问题,成为WiFi技术的一种补充。

WiFi is becoming more and more popular all over the world,and its technology is relatively mature.However,the signal of WiFi hotspot is unstable.Especially when there are more users,the speed of Internet access becomes slower.In recent years,a new technology of Li-Fi visible communication,which uses light-emitting LED bulbs as"hot spots"to transmit binary data in wireless communication,may solve this problem in the near future and become a supplement to WiFi technology.
