Abstract—In the 5G age, communication speed is getting faster, and as a result, IoT is getting more and more developed. In such a situation, the frequency band becomes insufficient and the higher frequency band is used. In this situation, LiFi technology is expected as an alternative to RF communication. This is because LiFi technology can be used effectively in enterprise conference rooms, which is the indoor environment using LEDs and many IoT devices. In this paper, the simulation is performed using OOK, 4-PAM, and 8-PAM in the enterprise conference room environment for the LiFi based network. The BER (Bit Error Rate) and the throughput of pulse modulation are calculated and compared according to the LiFi Standard to analyze the link performance and also evaluate the feasibility of employing LiFi technology in the conference room for providing the higher data support and more secure connection over conventional RF communication networks

Index Terms—LiFi, VLC, pulse modulation, OOK, 4-PAM, 8-PAM
