Optical camera communication for smart cities

Nowadays, the study of viable applications for smart cities has the direct interest of the research community. The generalized use of LED-based devices with larger dimensions and affordable costs, and the insertion of cameras with better characteristics in devices such as tablets and smart-phones, impulse the use of Optical Camera Communication (OCC) as a practical solution for future Internet of Things (IoT) and smart cities implementations. A real long distance OCC system for relatively slow data rate applications in smart cities is described along with its advantages and possible difficulties. A real scenario experiment has been held showing the viability of the proposed system.
