LED-Based Visible Light Communication and Positioning Technology and SoCs

The rapid deployment of high-energy-efficiency, solid-state light emission diode (LED) lighting devices, replacing the conventional luminaires devices, brings unprecedented opportunities for alternative optical wireless communication and navigation applications. This paper reviews the state-of-the-art of LED-based visible light communications (VLC) and positioning (VLP) technologies with a focu...

Integrated system of white LED visible-light communication and power-line communication

Real-time white-light phosphor-LED visible light communication (VLC) with compact size.

In this demonstration, we first demonstrate a real-time phosphor-LED visible light communication (VLC) system with 37 Mbit/s total throughput under a 1.5 m free space transmission length. The transmitter and receiver modules are compact size. Utilizing our proposed pre-equalization technology, the ~1 MHz bandwidth of phosphor LED could be extended to ~12 MHz without using blue filter. Thus, the...

Is blue optical filter necessary in high speed phosphor-based white light LED visible light communications?

Optical blue filter is usually regarded as a critical optical component for high speed phosphor-based white light emitting diode (LED) visible-light-communication (VLC). However, the optical blue filter plays different roles in VLC when using modulations of on-off keying (OOK) or discrete multi-tone (DMT). We show that in the DMT VLC system, the blue optical filter may be unnecessary, and even ...

Visible Light Communication for Wireless Data Transmission

Visible Light Communication (VLC) technology, one of the advanced optical wireless communication technologies, in which light in the visible region (375nm-780nm) is used as a medium for data transmission is more secure and achieves high data rates as compared to conventional wireless technologies like Wi-Fi, Bluetooth, Wi-max etc., which use radio waves for communication. While using wireless i...
