After Philips Hue, Trulifi lights transmit and receive data by light

Signify, the Philips subsidiary behind Hue lighting, has announced even smarter lighting aimed at businesses: Trulifi lights can transmit and receive data using nothing more than light. Instead of using radio signals (such as WiFi, 4G/5G, Bluetooth, etc.), Trulifi uses light waves to enable highly reliable, secure two-way wireless communications at speeds far above most conventional workplace wireless technologies. Trulifi uses optical wireless transceiver technology built, or retrofitted, into Philips luminaires. This means customers don’t have to rip and replace their existing lighting infrastructure to receive great quality light and wireless connectivity.
