Abstract

Although the demand for wireless communication continuous to grow, the number of frequencies available in traditional data transmission is limited. Visible Light Communication (VLC) is a promising alternative communication method proven to work on high-end devices. However, large-scale adoption requires VLC to also work on everyday machines. Yet, no published research has proven effectiveness on low-end devices. This work describes how a communication system using light can be implement on a low-end smart phone, using a LED as a transmitter. Furthermore, it compares two methods of (de)modulation, namely On-Off Keying and Differential Manchester Code. Evaluation results demonstrate a working system with a maximum bit-rate of approximately 3000bps.
