“…The increase in gain value, as formulated by formula (18) due to the utilization of a smaller FOV, also significantly affects the SNR value obtained, as shown in Figure 5 (c). This result is closely related to the received power outlined in formula (20). Observing the downward trend in SNR, it is evident that system performance will decrease when utilizing a larger FOV, specifically 60 0 and 75 0 .…”

“…where A eff can be calculated using formula ( 14) [14]: (17) Based on formula (17), the A eff value depends on detector area ( 𝐴 𝑑𝑒𝑡 ), lens gain (g), filter transmission gain (𝑇 𝑠 ), field of view (FOV), and angle of incidence (ψ). The calculation of lens gain is formulated as follows (18) [14], [20][21][22]:…”

“…The subsequent observation is the performance of the proposed Li-Fi indoor multiplexing model, based on the influence of FOV variations ranging from 300 to 750. The mathematical formulation refers to formulas (17)(18)(19)(20), with FOV's influence extending to the fluctuating values of A eff , H LOS , and received power Pr. Similar to the previous research, the transmitter half angle was limited when m=1 or 60 0 with irradiance angle and incidence values of 20 0 for the movable LED panel scheme.…”

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.
