NLOS UV Li-fi at 71Mbit/s

eeNews Europe and Compound Semiconductor features "Researchers prove non line-of-sight UV Li-fi at 71Mbit/s"

‚Äč"Modulating the signal of an ultraviolet LED emitting at 294nm, researchers from King Abdullah University of Science & Technology (KAUST) have demonstrated a high-speed near-solar-blind communication link with a data rate of 71 Mbit/s."

"Among other things, there are low background solar radiation and low device dark noise for the UV-band, especially for the UVC/B band (100-280nm/280-315nm), making the communication link near-solar-blind and impervious to noise."

"What's more, because UV radiations are scattered by many molecules and aerosols present in the atmosphere, the UV band is particularly indicated to establish a non-line-of-sight (NLOS) communication link, with less restrictive requirements for pointing, acquisition, and tracking of the light beam."
