Conclusions
There is a shortage of RF spectra: most of them have been allocated
Traditional RF based wireless communication has arrived at a bottleneck to meet 5G requirement
Light communication technology is an ideal complement to RF systems in 5G technologies
Coexistence of RF and light communication technologies can fulfill the requirement of 5G communication
