Visible light and infrared bands of the optical spectrum used for optical camera\ncommunication (OCC) are becoming a promising technology nowadays. Researchers are proposing\nnew OCC-based architectures and applications in both indoor and outdoor systems using the\nembedded cameras on smartphones, with a view to making them user-friendly. Smartphones have\nuseful features for developing applications using the complementary metal-oxide-semiconductor\ncameras, which can receive data from optical transmitters. However, several challenges have arisen\nin increasing the capacity and communication range, owing to the limitations of current cameras\nand implementation complexities. In this paper, we provide a comprehensive analysis of the OCC\ntechnology requirements and opportunities using smartphone cameras from an implementation\npoint of view. Furthermore, we demonstrate an OCC system using a low frame rate smartphone\ncamera to particularly analyze the requirements and critical implementation challenges. Also, some\npossible solutions are provided with a view to improving the overall system capacity, communication\ndistance, and stability.
