LiFi Opportunities and Challenges

This paper motivates the need for a new spectrum for current and future wireless networks. Furthermore, it argues that wireless networks based on light waves are at a very mature state. To this end, we introduce a taxonomy that defines the four major developments in this field: i) visible light communications (VLC), ii) optical camera communication (OCC), iii) free-space optical (FSO) communications, and iv) light-fidelity (LiFi) and discuss these technologies in the context of industrial private networks. Finally, key existing challenges are discussed in detail, and an outlook is provided.
