What is it about?

Visible Light Communication (VLC) systems combine ambient lighting and wireless data transmission. The experienced channel in indoor VLC with multiple transmitters has fluctuations with sudden drops in frequency band. These varying frequency selective channels need solutions especially for mobile users. It is proven that LEDs should be aligned in hexagonal cellular structure and detector field of view should be arranged according to the cell dimension for flat fading channel characteristics all over the room.

Why is it important?

Our findings show that LEDs should be aligned in hexagonal cellular structure and detector field of view should be arranged according to the cell dimension for flat fading channel characteristics all over the room .

Perspectives

I hope this article gives a view about how to align the Leds in our homes and offices for probable future use of VLC systems for communication. My insight is that VLC will become popular soon and we shall be ready for this.
