Visible light communication applications in healthcare

Area of Science:

• Optoelectronics
• Wireless Communication

Background:

• Advancements in science drive the evolution of communication methods for enhanced security, health safety, and efficiency.
• Visible Light Communication (VLC) emerges as a novel data transfer technology utilizing the visible light spectrum.

Purpose of the Study:

• To explore the capabilities and limitations of Visible Light Communication (VLC) as an advanced communication method.
• To highlight the potential of VLC in offering secure, health-safe, and cost-efficient data transfer.

Main Methods:

• VLC utilizes visible light spectrum (384–789 THz) for data transmission.
• Data transfer speeds vary, with LEDs achieving up to 500 Mb/s, significantly faster than older methods.
• System components include light sources (LEDs) and receivers, with advancements enabling bidirectional communication using LEDs.

Main Results:

• VLC demonstrates potential for high-speed data transfer, with LEDs reaching speeds up to 500 Mb/s.
• While range is a limitation, data transfer up to 1-2 km has been achieved at lower rates.
• The use of LEDs ensures continuous illumination without brightness changes, making it safe for eye health.

Conclusions:

• VLC presents a promising alternative for secure and efficient data communication.
• Despite current technical challenges, VLC technology holds significant potential for future widespread adoption.
• Further research and development are crucial to overcome existing limitations for practical daily use.
