pureLiFi, the light communications technology company, that transmits data using light waves from ‘off-the-shelf’ LED bulbs, says they have doubled the previous levels of data rates. Li-Fi enables energy-efficient data transmission using LEDs in light fixtures.

The findings were made at the University of Edinburgh’s recently opened Li-Fi R&D centre. pureLiFi is a spin-out company from University of Edinburgh and its Chief Science Officer (CSO) and co-founder, Professor Harald Haas.

pureLiFi demoed the world’s first commercial Li-Fi product, Li-1st, during March at MWC 2014 and CeBIT 2014. pureLiFi’s Li-Fi wireless system went to market in January 2014 and continues to be in high demand from industry customers worldwide.

Professor Harald Haas said:

“At the Li-Fi centre in Edinburgh, we’ve established that we can still transmit data wirelessly at data rates close to 100 per cent when lights are dimmed to levels where they appear to be switched off altogether.”

“This latest development furthers the case for Li-Fi revolutionising wireless communications, helps keep pureLiFi at the forefront of research and commercialisation and shows that Li-Fi really could be the enabler of the Internet of Everything.”

Visible Light Communication (VLC) is the use of light to transmit data wirelessly. Li-Fi – a term coined by Professor Haas – is a technology based on VLC that provides full networking capabilities similar to Wi-Fi, but with significantly greater spatial reuse of bandwidth.
