Dominic Schulz
Heinrich Hertz Institute (HHI)
Optical wireless communication, also
denoted as LiFi, is the communication bylight and represents an alternative to radio
frequencies for wireless transmission. With
the properties of light, gigabit per second
data rates, mobility support and low
latencies, LiFi is a promising technology toserve the demanding requirements of future
IoT applications. In this talk our current workof LiFi for various use cases is presented
and the benefits for the IoT are highlighted.
