This research presents the integration of Visible Light Communication (VLC) and conventional Radio Frequency (RF) wireless networks to enhance the data rate for mobile users, compute coverage, and analyze the average user's rate in joint VLC and RF networks in an indoor environment. Specifically, this thesis aims to examine the challenges posed by hybrid RF/VLC-based cellular networks and consider certain fundamental structures or factors. On the other hand, considering the limitations of RF, Visible Light Communication emerges as a promising technology for interference-sensitive applications such as medical networks. In this thesis, we explore hybrid RF-VLC relay systems that are suitable for applications supporting user mobility. In this system, the end user, assumed to be inside a moving vehicle, is covered by an indoor VLC system, where indoor coverage refers to network coverage inside the vehicle. In contrast, data transmission in outdoor areas is carried out via multiple RF backhaul links. Additionally, it is assumed that the RF link is established by a relay. The performance of this system is analyzed in terms of outage probability and bit error rate (BER). Moreover, for cases where the average SNR on RF links or the optical power of the LED is high, the necessary analysis is conducted. The numerical results presented show that the use of multiple RF backhaul links can significantly improve the overall performance of the RF-VLC system.
