Constraints and Recent Solutions of Optical Camera Communication for Practical Applications

Visible light communication (VLC) has emerged as a promising technology for wireless due to its advantages of the vast optical spectrum, high energy efficiency, and no electromagnetic interference radiation. With widespread adoption LED infrastructure camera-equipped smart devices, camera (OCC) gained momentum pragmatic version VLC based on commercial off-the-shelf (COTS) devices. Compared with systems photodiodes (PD), information-carrying capability OCC enables it provide wide range services in areas intelligent transportation, indoor positioning, underwater communication, Internet Things (IoT). This paper presents brief overview system, focuses constraints affecting performance, offers feasible solutions dependable data transmission complex diverse scenarios. Finally, this summarizes potential extended applications OCC, hoping push advanced form toward practical deployments our daily lives.
