“…However, this type of communication cannot be used in case of specific conditions in targeted environment (because of fog or vapor for example). In these cases, the optical transmission by the laser or light emitting diode of infra-red (IR) or visible light (VL) [3 – 7] wavelength is completely useless because it has significant and inestimable attenuation [8] , [9] – 10] . Radiofrequency (RF) communication [11] , [12] represents a better solution in these specific situations.…”
