Abstract
LED‐to‐LED communication, in which an LED is used as both transmitter and receiver, is n ubiquitous technology that presents important advantages such as low‐cost devices and security enhancement. We investigate the performance of visible light LED‐to‐LED communication under realistic conditions. We analyze the impact on transmission performance imposed by different colors of LEDs and their combinations. In sum, our results evidence the importance of a correct LED setup. According to our results, lower frequency LEDs such as red and orange are highly efficient when used as receivers, while higher frequency LEDs are less sensitive and therefore more limited in these scenarios. Moreover, we highlight that the pattern created by a wide range of LEDs can be helpful for new visible light communication‐based mechanisms.
