Efficient Exploitation of Radio Frequency and Visible Light Communication Bands for D2D in Mobile Networks
The concept of device-to-device (D2D) communication, combining common radio frequency (RF) and visible light communication (VLC), is seen as a feasible way how to cope with spectrum crunch in the RF domain and how to maximize spectral efficiency in general.In this paper, our objective is to decide when RF should be utilized or if VLC proves to be t
