Visible Light Communication (VLC) is a new paradigm that could revolutionize the future of wireless communications. In VLC, information is transmitted by modulating the visible spectrum (400–700 nm) used for illumination
Visible light communication (VLC) refers to a communication technology that uses visible light as the light carrier for data transmission and illumination. Today, light-emitting diodes (LEDs) at visible wavelengths (380 nm ~ 780 nm) are actively developed (Schubert, 2003) for use as communication sources, and of course, silicon photodiodes exhibit good responsivity in the visible wavelength region as a receiving element. The transmission channel is air, whether indoors or outdoors.
With a variety of vision solutions that adapt to the fluidity of today’s hybrid environments, ViewSonic showcases large business displays for communication and messaging, interactive displays that facilitate collaboration between teams, and budget friendly for classrooms and small meeting rooms projector. Other solutions that can help ProAV partners and their customers’ changing needs include professional-grade monitors for color-sensitive projects and small touch monitors that can expand digital workspaces or be used as a second monitor.
Whether the link is directional or non-directional depends on whether the sender has a direction towards the receiver. The decision of whether a link is LOS or non-LOS depends on whether there is a barrier blocking the light transmission between the transmitter and receiver. In a VLC system, the non-directional LOS link is important because general lighting operates in a LOS environment, which is not focused or directional.
