“…Li-Fi technology offers wide bandwidth and high data rates, providing opportunities for enhancing both transmitter and receiver efficiency and capacity [18]. However, Li-Fi technology faces limitations in accurately positioning devices for lineof-sight (LOS) conditions, necessitating the use of multiplexing systems to boost bandwidth efficiency, especially in indoor settings [18,19]. Research has proposed multiple input multiple output (MIMO) scenarios, with findings indicating that 2x2 and 4x4 channel multiplexing schemes result in nearly identical received power values.…”

“…Research has proposed multiple input multiple output (MIMO) scenarios, with findings indicating that 2x2 and 4x4 channel multiplexing schemes result in nearly identical received power values. However, increasing the channel spacing value, from 5 nm to 25 nm, affects system performance, where the 25 nm channel spacing scenario demonstrates better performance [18], although reliable observation distance is still limited to 3 meters. Research [18] only reached a distance of 3 meters, our proposed research was made at a distance of 3-5 meters to see the quality of system modeling based on increasing transmission distance.…”

Li-Fi technology faces a critical challenge in achieving line-of-sight (LOS) connectivity while also optimizing bandwidth efficiency for high-speed data transmission. To address these issues, this research introduces a channel multiplexing model for Light Fidelity (Li-Fi) communication, employing movable LED panels. The study evaluates the model's performance by varying channel number, transmitter half-angle values, and field of view (FOV) parameters over a 3 to 5-meter transmission range. Results demonstrate that the proposed Light Fidelity indoor multiplexing model excels with an inter-channel spacing of 25 nm, particularly for Mux 2x2 and Mux 4x4 schemes. Longer-wavelength channels exhibit lower bit error rates (BER) and superior Q-factor values compared to others. Reliable performance within the 3 to 5-meter range is achieved with transmitter half-angle values of 30 0 and 45 0 , enhanced by adopting a higher Lambertian order value (m>1) to ensure signal quality with a superior signal-tonoise ratio (SNR). Additionally, employing a FOV of 30 0 solely complies with the optical communication standard (BER < 10-12) for distances spanning 3 to 5 meters.

Light Fidelity (LiFi) based on data transfer with visible light offers a more profound solution to the wireless communication paradigms. This study brings focus on how the line-of-sight (LOS) channel can be used to enhance the performance of a LiFi network. We discuss the LOS channel characteristics, system features, and deployment considerations with respect to evolution and prospects. Experimental modelling and conditions testing involve Q-factor, bit error rate (BER) and data rates analysis. The results presented in this study suggest that both the characteristics of channels and the data transmitted affect the efficiency of the network; higher data rates and longer distances lead to increased BER and lower Q-factor. The outcome of this study reveals key factors which influence the channel performance and provides a guideline that would be beneficial in advancing the LiFi system implementation for different applications. It is hoped that the findings of this study are useful for network engineers and researchers to design better and more flexible LiFi systems for various communication applications.
