Abstract
The absence of interference by radio waves, due to the use the unlicensed light spectrum provided by light-emitting diodes (LEDs) sources, is one of the main advantages of visible light communication (VLC) systems in health classified areas. The robustness of a stable and reliable VLC system, for application in intensive care medical environments, is experimentally demonstrated in this paper. A proof-of-concept experimental setup is presented and the results described to confirm the performance of on-off keying (OOK) schemes based on Manchester coding. The experimental results show that the transmission, of real data provided by a patient monitoring equipment, over a VLC link of 1.5 m, was successfully achieved with the wide range of LED bias current between 10 and \(\approx 700\) mA.
