Li-Fi is a term coined by Professor Harald Haas, a renowned professor in the field of Mobile Communications. Also popular as Technology innovator and expert in the field of visible light communication and mobile.
Light Fidelity, better known as Li-Fi is a fully networked, high-speed and bi-directional wireless communication system. It uses the visible light of an electromagnetic spectrum and transmits data. It falls under the category of OWC. OWC is Optical Wireless Communications which includes communication modes like Infra-Red, Ultraviolet etc. Uniqueness of Li-Fi lies in the fact that energy emitted from light can be used for communications along with illumination.
LEDs (Light Emitting Diodes) seems to be major boon for Li-Fi technology, because of the technology used for manufacturing LEDs enables modulation at very high speeds which can be detected by photo-detector devices and then is later converted back to electrical current which is not visible to human eye.

Key Areas where Li-Fi can be useful:
- Navigation Services
- Mobile Connectivity
- Smart Lighting
pureLiFi is one of the pioneers and global leaders in Li-Fi technology. It was established in 2012.
They have a team of highly qualified professionals from the fields of Mobile technology, Communications, Management. Professor Harald Haas is the Chief Scientific Officer and company also work with university of Edinburgh for working on breakthrough technologies in the field of Li-Fi.
- Russell Griggs OBE- Chairman
- Harald Hass- Co-Founder and interim CEO
- Mostafa Afghani- Co-Founder and CTO
- Harald Burchardt- COO
pureLiFi has recently tied up with Lucibel, a French LED lighting specialist and will be working on developing prototype for Europe’s first LiFi and is expected to be launched later this year.
pureLiFi has raised closed to £9M with latest funding coming from Temasek, a Singapore investment firm where company has raised £7M in Series B funding.
With the bandwidth shrinking day by day, LiFi comes as a hope for speedy and more secured connectivity.
