Our latest research on load balancing in hybrid WiFi/LiFi networks has shown an interesting result: There is a direct relationship between WiFi throughput and LiFi throughput. Specifically, as the LiFi throughput increases, so does the WiFi throughput, and vice versa. This is despite the fact that both systems use entirely different parts of the electromagnetic spectrum, and also that there is no interference between these systems. This research work has been accepted for publication by the IEEE Journal of Lightwave Technology, and a pre-print can be downloaded here.
