Analysis of Bit Rate and Distance Variation on Multiplexing System of Indoor Li-Fi Technology Using Movable LED Panel

The major problem of using light fidelity (Li-Fi) technology is still limited to the line sight (LOS) conditions, which poses a challenge perform bandwidth efficiency support increased bit rates, especially for indoor use. In addition, distance between lamp driver (transmitter) and receiver becomes critical discussion determine characteristics propagation losses. Therefore, this study focuses on analyzing performance an Li-Fi multiplexing system movable LED panel (LP) based parameters rate variation multiple-input multiple-output (MIMO) 2x2 4x4. parameter analysis signal quality included optical electrical spectrum characteristics, signal-to-noise ratio (SNR), error (BER), Q-factor parameters. Based results, increase in significantly increases BER value decreases value. Both 4x4 mux systems can meet standards up 30 Mbps at LOS 3 meters, while 40 Mbps, there are no channels that ITU-T standard. received 4 only reach standard 20 all channels. However, channel model have values Mbps. decrease SNR affected by insignificant. it opportunity further observation proposed system, detection scheme, or responsivity, processing side be reliable higher rate.
