One day, in the not too distant future, you may be able to connect to the Web through your lights instead of your router, which could eventually extend your broadband Internet connection into previously inaccessible rooms and floors. Signify (the maker of smart lamps Philips Hue) announced the creation of Trulifi, a new high-speed version of its LiFi (Light Fidelity) technology that transmits data using light. We already seemed that these systems had been tested, but now it is becoming a reality. Or at least, a reality for business and industry: Trulifi heads first to offices, hospitals, and other large buildings, though it may eventually end up in our basements and attics.
The fantastic light
Here's how it works: A wired connection runs through each room and connects the lights inside. These LEDs then transmit data signals to laptops in which a recognized USB access key is installed, verifying the connection. The lights can connect to each other as you move around the room, making it ideal for open-plan offices. Signify also talks about Trulifi's ability to work in places where the radio spectrum (Wi-Fi and 4G) might be congested or restricted. LiFi only works as far as light can travel, it doesn't reach walls. While this is obviously a problem for a partitioned space, it means more peace of mind for businesses that are concerned about data being hacked from outside their building. As we said, Trulifi isn't quite ready for home use yet, but with the first business partners signing up for the technology, it's a wireless streaming option to watch, along with the growth of 5G.
