Faulkner,M. M. Vazquez,M. Bech,Frank Geilhardt,Ralf-Peter Braun,Xiong Deng,Eduward Tangdiongga,A.M.J. Koonen +21 more
TL;DR: Li-Fi needs an open architecture, consensus building towards standards, a roadmap to support future IoT and technology demonstrations in real environments, such as indoors, manufacturing, logistics, conference rooms and outdoors for fixed-wireless access.
Journal ArticleDOI
A Physical Layer for Low Power Optical Wireless Communications
Malte Hinrichs,Pablo Wilke Berenguer,Jonas Hilt,Peter Hellwig,Dominic Schulz,Anagnostis Paraskevopoulos,Kai Lennert Bober,Ronald Freund,Volker Jungnickel +8 more
TL;DR: A physical layer based on high-bandwidth on-off keying modulation allows for highly efficient transmitter frontend designs that avoid operation of amplifier stages in a resistive mode, which has the potential of reducing their energy usage by an order of magnitude.
Proceedings ArticleDOI
LiFi Experiments in a Hospital
Sreelal Maravanchery Mana,Peter Hellwig,Jonas Hilt,Kai Lennert Bober,Volker Jungnickel,Klara Hirmanova,Petr Chvojka,Radek Janca,Stanislav Zvanovec +8 more
TL;DR: LiFi channel measurements in a neurosurgery room of Motol University Hospital in Prague are presented and achievable data rates for different LiFi transmission schemes are reported.
