Signify uses LED lighting to wirelessly transfer 150 Mbps data via LiFi
Signify has launched a new range of LiFi systems tthat transfer high-speed wireless data, using existing lighting infrastructure. It is being aimed at professional markets including offices, hospitality, retail, industry and healthcare.
The range, branded Trulifi, uses existing and future professional lighting. 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 lighting. This means users don’t have to rip and replace their existing lighting infrastructure.
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 lights providing wireless connectivity at speeds up to 150 Megabits per second (Mbps) over large spaces, such as meeting rooms and office floors. 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, suitable for connecting devices.
Potential applications include connecting robots or machines in RF harsh environments like industrial plants, or hospitals where RF communications may not be permitted.
