Speaker: Dr. Hani Elgala, Boston University


The demand load of streaming traffic ranging from running concurrent applications on smartphones and tablets to HD video streaming is the primary consumer of capacity on wireless networks. The existing RF wireless technologies suffer from the spectrum scarcity and the ability to grow capacity is limited. Visible light communications (VLC) using light- emitting diodes (LEDs) is an emerging technology that allows data communication to be combined with illumination. VLC has the potential for being an attractive complementary to realize indoor broadband wireless access and to off-load data from existing Wi-Fi and cellular networks. In this talk, we highlight the potential applications of VLC, give an overview on the current status of research, and discuss the emerging research challenges as well as a number of solutions that have been proposed.
