    Li-Fi in the Paris Metro

    Li-Fi in the Paris Metro

    LED Light Li-Fi

    One of the most ambitious public projects to deliver Internet service via LED light appears to have hit a snag or two.

     

    RATP, the state-owned group that runs public transportation in the Paris region, hopes to equip 302 Metro subway stations and 66 RER commuter rail stations with Li-Fi, the Wi-Fi-like service that can transmit data by using LED lights rather than Wi-Fi's radio signals.

     

    The rail operation conducted extensive trials before setting out to equip stations a year ago, as LEDs Magazine sister publication Lux has reported. But it has managed so far to outfit only one location, according to sources that LEDs contacted inside government and vendor circles.

     

    And the lone site — the RER's La Défense station — is using a one-way-only technology to deliver navigation assistance, rather than providing full Internet service, one source said. At La Défense, the service is geared toward helping visually impaired people navigate their way.

     

    At one point several months ago, one of the sources told LEDs that it was difficult to provide a progress report because the Li-Fi subject at RATP was “delicate.” The source did not elaborate.
