High-speed Internet through your lights with LiFi

    Where there’s light… there can be wireless communication through LiFi.

    Introducing Trulifi, a new range of LiFi systems: great quality light and a reliable, fast internet connection.


    By 2020, more than 50 billion devices will connect to the Internet, most wirelessly. This is placing wireless communication under increasing pressure. Put simply, the radio spectrum is becoming congested. What’s more there are areas where radio frequency wireless communication is not permitted or the best fit.

    Trulifi by Signify is the perfect solution. It’s a range of LiFi systems, providing two-way wireless communication that’s reliable, secure and fast.

    High-speed Internet through your lights with LiFi

    Our Trulifi systems modulate light waves to transmit data. A USB access key plugged into a laptop or tablet receives data and sends data back to a transceiver. By leveraging lighting infrastructure, Trulifi customers get the best of both worlds: great quality Philips light and a reliable, secure, high-speed wireless connection.

    Plug-and-play. Trulifi can be retrofitted into existing luminaires: an all-in-one solution to declutter your ceiling.
