Bidirectional visible light communication

Optical Engineering, 2020
Visible light communication (VLC) is a data transmission technology that uses the LED lighting infrastructure to simultaneously illuminate and communicate. The ubiquitous existence of LED lamps opened a new opportunity for addressing VLC in many indoor communication scenarios.

Visible Light Communication-Based Outdoor Broadcasting

2021 17th International Symposium on Wireless Communication Systems (ISWCS), 2021
In this paper, we explore visible light communication (VLC) as a wireless connectivity solution to enable outdoor broadcasting for public safety systems. Unlike indoor VLC broadcasting systems which build upon LED ceiling luminaries, outdoor VLC systems use ubiquitous streetlights as transmitters.

Precoded visible light communications

2013 9th International Conference on Information, Communications & Signal Processing, 2013
Multiple input multiple output (MIMO) technology appears attractive for indoor visible light communication (VLC) systems as multiple light-emitting diodes (LED) sources are typically deployed for indoor environment. Most of current indoor MIMO VLC systems utilize single user terminal scenario to investigate the performance of the system.

Visible Light Communications

2020
Current wireless communications need to fulfill two important requirements according to different applications. The first is to achieve high-speed and long-distance data transmission, and the second is to realize ubiquitous and short-range information services.

(In)visible light communication

ACM SIGGRAPH 2014 Emerging Technologies, 2014
Consumer devices transform into interactive communication interfaces when visible light is used to transmit data. At home, during work or leisure time, light bulbs, toys, or other electronics and accessories can be used as environmental sensors, and act as user interfaces based on their location, play pattern, or other context provided by the Internet.

Visible-light communications and light fidelity

2020
This chapter starts by explaining the significantly increased interest in visible-light communications (VLC) and light fidelity (LiFi) during the last 10 years. Next, a taxonomy of the various optical wireless communications technologies is provided, and we discuss their key discriminating features.
