High Throughput Mobile Visible Light Communication

Visible Light Communication (VLC) data capacity can be in the order of Tera-bits-per-second (Tbps) as it operates on an unrestricted terahertz band (400–700 THz) of the electromagnetic spectrum. However, in practice, all the existing VLC systems are limited in data rate, in the range of Kbps-Mbps. In this paper, we introduce a novel state-of-art VLC system for achieving ultra high data rates from the perspective of designing a high-speed VLC receiver. In our designed VLC receiver architecture, along with high sampling rates photodiode, we integrate an image sensor-like shutter mechanism that filters noise and interference. Through this unified design, the receiver will be able to select the exact area over which the transmitted signal is detected on the array, and thus isolates signal from noise to improve the Signal to Noise Ratio (SNR) significantly which leads the ultra high-speed in VLC systems. In this paper, we discuss the design details of our proposed VLC prototype and study the feasibility of the system through proof-of-concept experimentation.
