A Software-Defined Multi-Element VLC Architecture

In the modern era of radio frequency (RF) spectrum crunch, visible light communication (VLC) is a recent and promising alternative technology that operates at the visible light spectrum. Thanks to its unlicensed and large bandwidth, VLC can deliver high throughput, better energy efficiency, and low cost data communications. In this article, a hybrid RF/VLC architecture is considered that can simultaneously provide light- ing and communication coverage across a room. Considered architecture involves a novel multi-element hemispherical bulb design, which can transmit multiple data streams over light emitting diode (LED) modules. Simulations considering various VLC transmitter configurations and topologies show that good link quality and high spatial reuse can be maintained in typical indoor communication scenarios

A Software-Defined Multi-Element VLC Architecture For High Spatial Reuse

Visible light communication (VLC) is an emerging wireless technology that offers a promising set of possibilities for applications that need more capacity than legacy radio frequency (RF) can offer. Free-space-optical (FSO) communication is VLC's general form spanning infrared bands, and it has an upper hand on traditional RF systems due to license-free spectrum, inherent security and containment of beams, energy efficient communications, and high transmission rates. In this work, we consider a hybrid RF/FSO mechanism to transmit multiple data streams over multi-element VLC modules. We evaluate a novel model of multi-element hemispherical design that can provide good lighting and communication coverage across a room. Simulation results are presented to evaluate the link quality performance of the hemispherical design with hundreds of LED transmitters, organized in different configurations
