LiFi: Self-powered Li-Fi

Li-Fi (Light-Fidelity) is high speed wireless communications through light emitting diodes (LEDs). Li-Fi has first been coined by Prof. Haas in his TED talk:

We investigate Li-Fi in the context of novel 5G technologies to solve the looming spectrum crisis in wireless communications. Transmission speeds of up to 10 Gbps have been demonstrated in our lab and it has also been shown that Li-Fi does not required line-of-sight. Therefore, we are now studying wireless system concepts based on Li-Fi technology. We refer to a cellular Li-Fi network as an attocell network as the cell sizes are smaller than in a typical radio frequency (RF) femtocell network potentially unlocking very high area spectral efficiencies.

Self-powered Li-Fi

In this project we investigate energy harvesting concepts for Li-Fi systems in combination with energy-efficient transceiver technologies. This requires energy-efficient digital modulation techniques and low computational complexity algorithms. Therefore, investigations of new MAC and synchronisation techniques as well as novel circuit designs are all within the scope of this project. The project primarily targets sensor network applications.
