Signify launched a new range of LiFi systems. The range, branded Trulifi, leverages existing and future professional luminaires. 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.
Trulifi overcomes the increasing congestion of the radio spectrum and is perfect for areas where radio frequencies don’t work well, or at all, or are not permitted.
The new range comprises Trulifi-enabled luminaires providing wireless connectivity at speeds up to 150 Megabits per second (Mbps) over large spaces, such as meeting rooms and office floors. There is seamless handover between each Trulifi-enabled luminaire enabling users to roam around. The speed is fast enough to stream simultaneously 30 1080p HDTV movies. A USB-access key, plugged into a laptop, is needed to receive the LiFi signal and acts as an emitter to send data back to the luminaire.
The Trulifi range also includes a fixed point-to-point system, up to 250 Mbps speed, which acts like a wireless cable, ideal for connecting devices. Potential applications include connecting robots or machines in radio frequency (RF) harsh environments like industrial plants, or hospitals where RF communications may not be permitted, or where there’s a need to send and receive large data files securely and quickly.
