The Trulifi family of LiFi systems from Signify (formerly Philips Lighting) delivers reliable, secure, high-speed wireless communication over a company’s lighting infrastructure. Instead of using radio signals (e.g. WiFi, 4G/5G, Bluetooth), LiFi uses light to send and receive data between optical wireless transceivers built into Philips luminaires and a USB access key plugged into a laptop. It offers guaranteed speeds of up to 150 megabits per second – fast enough to stream 30 1080p HDTV movies simultaneously – with seamless handover between light points, enabling employees to roam around an office and not lose connectivity.
The LiFi spectrum is more than 1,000 times the size of the radio spectrum, making it ideal for busy areas such as multi-tenancy buildings, stations, airports and public venues; it can be used where radio frequencies don’t work well or at all (e.g. underground) or where they are not permitted; and it is secure, thanks to AES 128 encryption, the need for a USB access key and because light waves cannot penetrate walls.
An early adopter of the technology, Belgian marketing agency Claerhout Communication Campus has retrofitted a Trulifi 6002 system to four Philips LED luminaires in a large meeting room at its office in Ghent. Business Development Manager Christoph Ruys said: “We wanted good quality, energy-efficient lighting and wireless connectivity capable of handling high resolution images, artwork and big data files. We’ve gone from offering our staff and clients 5 Mbps to a blistering 150 Mbps, and we can roam around freely as one light point hands off to another seamlessly. Trulifi adds an extra layer of security as light can’t pass through walls, so what’s in the room stays in the room. This is truly game-changing technology.”
