TitleWireless Connectivity through Lighting: Techniques and Applications of Visible Light Communications

 

Abstract:

LED lamps have recently become the technology of choice for lighting in many environments,   from indoor office spaces to outdoor vehicular use.  These LED lamps can be modulated at relatively high speeds, opening up the possibility to use them to provide simultaneously illumination and data transmission, so-called visible light communications (VLC).  One of the most compelling applications for VLC is in large unobstructed indoor spaces where many users desire concurrent high-speed connectivity, such as conference centers and classrooms; Wi-Fi fails here because of its limited spectrum re-use.  Other promising applications include vehicle-to-anything (V2x) communications, indoor positioning, and transmission inside airplane cabins.  Yet VLC systems suffer from the limited bandwidth of inexpensive LEDs as well as from intersymbol interference (ISI) imposed by channel multipath. In this talk we introduce transmission schemes to increase the data throughput of single-user VLC  systems, as well as adaptive networking techniques that can provide mobile network access for many simultaneous  users.
