Smart lights of the future are coming to help boost your Wi-Fi

[sincity]

One day in the not-too-distant future you could be connecting to the web via your lighting fixtures rather than your router – potentially extending your broadband internet into rooms and on to floors where it was previously unable to reach.

Signify (the maker of the Philips Hue smart lights) has announced Trulifi, a new high-speed version of its LiFi (Light Fidelity) technology that transmits data over light. We've previously seem these systems tested, but now it's becoming a reality.

Or at least, a reality for business and industry: Trulifi is being aimed at offices, hospitals, and other large buildings to begin with, though it could eventually make its way into our basements and attics as well.

The light fantastic

Here's how it works: a wired connection runs through to each room and hooks up the lights inside it. Those lights then beam out data signals to laptops that have a recognized USB access key installed, verifying the connection.

Lights can pass off connections to each other as you move around the room, making it ideal for open plan offices. Signify is also talking up Trulifi's ability to work in places where the radio spectrum (Wi-Fi and 4G) might be crowded or restricted.

LiFi only works as far as light can travel though – it doesn't reach through walls. While that's obviously a problem for a partitioned space, it does mean extra peace of mind for companies worried about data hacks from outside their building.

As we've said, Trulifi isn't ready for home use just yet, but with the first commercial partners signing up for the technology, it's a wireless streaming option to keep an eye on – alongside the growth of 5G.
