“Li-Fi, a super-fast alternative to Wi-Fi, has been proven capable of sending data at up to 1GBps in real-world tests,” Adam Boult reports for The Telegraph. “At that speed, 100-times faster than current Wi-Fi technologies, a high-definition film could be downloaded in a matter of seconds.”
“In a pilot scheme carried of by Estonian start-up Velmenni, the technology was trialled in offices and industrial environments in Tallinn,” Boult reports. “Li-Fi uses light to beam information through the air. Writing about the technology earlier this year, The Telegraph’s Sophie Curtis said: ‘Light is already used to transmit data across fibre optic networks at high speed. These work by guiding the light along optical fibres using total internal reflection, so that no information is lost along the way. However, transmitting information by beaming light through the air is more difficult, because there is no ‘light tunnel’ to guide the signal to where it needs to go.'”
Boult reports, “Li-Fi technology was originated in 2011 by Professor Harald Haas of the University of Edinburgh, who demonstrated that, with a flickering light from a single LED, he could transmit more data than a cellular tower.”
