Riding the Wave...Visible Light Communication System
Relay-Assisted VLC and Underwater VLC Communication systems
Due to huge demand of the wireless connectivity and data use, mobile communication standards advanced rapidly to support the world needs by introducing new waveforms and spectrum. One of the ways 5G and beyond will enable this is by tapping into new, unused bands at the top of the radio spectrum. These high bands are known as millimeter waves (mmwaves). Later versions of 5G or 6G will also allow things like IoT devices to connect to mmwaves, VLC, as well as allow for use of unlicensed spectrum to increase speeds some more.
VLC links present a very high bandwidth that allows muchhigher data rates. VLC exhibits also immunity to interferencefrom electromagnetic sources, unlicensed channels, very lowpower consumption and no health hazard. VLC is appealing fora wide range of applications including reliable communicationswith low latency such as vehicle safety communication. In this talk we will address the major advantages of VLC technology and variety of itsapplications. We will present anoverview of the current developments of the hybridRF/VLC systems, VLC relay assisting, underwater VLC link analysis and present the advantage of the capacity of VLC links and its connectivity. Hybrid RF/FSO and Hybrid mmwave/FSO systems as backhaul systems will be briefly introduced.
