High-speed breakthrough brings Li-Fi closer

THE UNVEILING of a high-speed version of Li-Fi has brought the revolutionary technology closer to widespread adoption.

French manufacturer Oledcomm has demonstrated its latest model which gives 16 users simultaneous access to 100Mbps internet connectivity via visible light from LED luminaires, rather than tradition Wi-Fi.

The LiFiMax platform requires the users to plug a transceiver dongle into their device, which allows for 100 Mbps download and 40Mpbs upload. The download information is ‘embedded’ in the high-frequency visible light from the light fitting.

LiFiMax – which will be available this September and costs £700 (€780, US$900) – was launched at the CES Show in Las Vegas and is compliant with Windows, MacBook and Linux-based devices. The luminaires are connected to an internet access point via a network cable and feature a Li-Fi-compatible driver which converts data into modulated light.

Oledcomm founder Benjamin Azoulay says the LiFiMax product has been 10 years in development. He believes Li-Fi’s early adaptors will in specialist applications.  These include 'the health community or electro-sensitive people for whom Wi-Fi is prohibited.

‘There’s also a stronger security scenario since a broadcast of this type is more difficult to intercept than Wi-Fi. Our technology can also appeal to those seeking selective connectivity - we are limited to a place - or for those who try to avoid being connected all the time and everywhere’.

The introduction of LiFiMax follows the launch of a downlight in November from fellow French manufacturer Lucibel which offers internet speeds of up to 54 Mbps.

The world’s first Li-Fi luminaire was unveiled at the LuxLive exhibition in London in 2017. That innovation – developed by Lucibel and  Scottish start-up pureLiFi – was first to put all the necessary Li-Fi components in a single unit. It is able to support between eight to 16 users at once, and deliver data at rates of 45 megabits per second.

Last February, a  US technology company showed a prototype of  the world’s first LED panel with integrated Li-Fi. Developed by Virginia-based VLNComm, the panel is capable of a download speed of 108Mbps and an upload speed of 53Mbps, and provides 48 square metres of coverage.

Around 15 users can simultaneously receive data through the use of standard white LEDs.

Meanwhile US firm Linmore launched the first-ever Li-Fi battens, designed as retrofit for fluorescent luminaires. These light fittings deliver data speeds of up to 43 Megabits-per-second (Mbps) up and down.
