LiFi无线通信的研究进展

Research Progress of LiFi Wireless Communication

摘要: 5G通信技术和WiFi让人们的生活越来越便捷，可见光通信典型代表LiFi也引来人们的日益关注。近年来，可见光通信在各领域的应用更加广泛，只要有光的地方，我们就可以随时进行信号传输，而不像WiFi热点一样受限制。但LiFi也存在一定的缺点，由于其通过光传输数据，当可见光在室外传输时会受到太阳光的干扰，同时如果光线被遮挡也会影响传输数据，这是目前光通信研究的一些难题。WiFi和LiFi单独使用时有缺陷，把两者结合使用也不失为一个好的办法。

Abstract: 5G communication technology and Wireless Fidelity (WiFi) make people’s life more and more con-venient. However, Light Fifelity (LiFi) has attracted increasing attention with the rapid develop-ment of communication technology. In recent years, the visible light communication is more widely used in various fields where there is light, you can communicate online without limitation like WiFi hotspots. However, there are some disadvantages to Lifi; if the sun too bright or the light is blocked, it cannot transmit data which are some problems in current research. So it will be a good method by using the combination of the WiFi and LiFi.
