- Wireless Technology
- Automotive Systems
Background:
- Visible Light Communications (VLC) is a promising wireless technology for diverse applications.
- Existing VLC systems often require dedicated transmitters and receivers.
- Integrating communication capabilities into existing vehicle infrastructure is desirable.
Purpose of the Study:
- To design, implement, and evaluate a novel in-vehicle VLC system.
- To provide optical wireless communication for car passengers.
- To explore the use of decorative optical fibers for data transmission within a vehicle.
Main Methods:
- A VLC emitter was integrated into a vehicle's ambient lighting system, utilizing a 3 W LED distributed via 500 decorative optical fibers.
- A mobile VLC receiver was employed to capture the transmitted data.
- The prototype system was installed in a car and tested under relevant working conditions.
Main Results:
- The experimental evaluation demonstrated the viability of the proposed in-vehicle VLC concept.
- A data rate of 250 kb/s was achieved.
- A Bit Error Rate (BER) lower than 10-7 was recorded.
Conclusions:
- The proposed system successfully integrates VLC with decorative optical fibers for in-vehicle communication.
- This work presents a novel application of VLC technology, utilizing distributed light sources for data transmission.
- The findings open new avenues for utilizing VLC in automotive environments.
