Abstract: The present invention relates to a Light Fidelity (Li-Fi)-based intra-vehicular data transmission system configured to facilitate high-speed wireless data communication within a vehicle. The system comprises a data source module, a Li-Fi transmitter, a light-emitting diode (LED) light source, a Li-Fi receiver, and a portable device interface. The system employs visible light communication by modulating the intensity of light emitted by the LED light source to transmit data optically, which is received and converted into electrical signals by a photodiode-based receiver. The system is configured to facilitate data exchange between compatible devices within the vehicle environment. The use of visible light communication reduces reliance on conventional radio frequency (RF)-based transmission and may minimize electromagnetic interference in suitable operating environments. The proposed system supports efficient intra-vehicular data transmission and is suitable for applications involving multimedia sharing and wireless communication between in-vehicle devices. 5 Claims & 2 Figure.
