Breaking the limitations of visible light communication through its side channel

Visible Light Communication (VLC) is a promising technology for future wireless communications. By modulating the visible light - -that has about 10,000x larger frequency band than that of radios - -to transmit data, VLC has the potential to provide ultra-high-speed wireless connectivities. However, it also has limitations such as i)...

Bracelet+: Harvesting the Leaked RF Energy in VLC with Wearable Bracelet Antenna

Visible Light Communication (VLC) is widely considered a promising technology for the coming 6G networks. Recent studies show that a VLC transmitter not only emits visible light signals but also leaks RF signals during the transmission. In this work, we devote effort to harvesting the free leaked RF energy from VLC transmissions. We observe that...
