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: http://bit.ly/tedvlc.
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.
Interference Management in Optical Attocell Networks
This project addresses the issue of co-channel interference in an optical attocell network. The project will develop novel interference cancellation techniques which are tailored to Li-Fi signals. Moreover, the project will study cell cooperation techniques as well as potential interference avoidance techniques taking into account the particular signal propagation characteristics in the visible light and infrared spectrum.
