The objective of the work is to analyze the downlink signal-to-interference-plus-noise ratio (SINR), transmission rate, bit error rate (BER), and average BER in terms of the irradiance angle of the receiver’s orientation and incident light and transmitter-to-receiver separation distance. The research considered two Light Fidelity (LiFi) access points (APs) for this analysis in a smart classroom context. The work derived the best favorable irradiance angle in terms of transmitter–receiver separation at which user devices achieve the highest SINR and transmission rate considering both two-dimensional (2D) and three-dimensional (3D) coverage areas. Moreover, the work analyzed SINR-based BER and average BER for the same communication scenario. The research derived that 47° to 50° irradiance angles of the receiver’s orientation and incident light offer the most favorable performance.
