    PureLiFi Teases Smaller LiFi-X-Style Dongle

    BARCELONA—PureLiFi is working on a LiFi dongle that’s roughly half the size of the LiFi-X device launched at last year’s Mobile World Congress. PCMag was shown 3D-printed prototype ...

    How Does it Work

    Light Fidelity (Li-Fi) is a bidirectional, high-speed and fully networked wireless communication technology similar to Wi-Fi. The term was coined by Harald Haas[1] and is a form of visible light ...

  • BARCELONA—PureLiFi is working on a LiFi dongle that’s roughly half the size of the LiFi-X device launched at last year’s Mobile World Congress. PCMag was shown 3D-printed prototype cases for the new device, and while we weren’t allowed to take any pictures, we can say that one of them was about the same size and...

  • Light Fidelity (Li-Fi) is a bidirectional, high-speed and fully networked wireless communication technology similar to Wi-Fi. The term was coined by Harald Haas[1] and is a form of visible light communication and a subset of optical wireless communications (OWC) and could be a complement to RF communication (Wi-Fi or cellular networks), or even a replacement...

  • Li-Fi looks to be yet another disruptive technology, this time in communication, which has remained with the same wireless technology since the year 2000.

  • Someday the last leg of our communication networks might not depend on a modulated radio signal but on a modulated light signal from an LED bulb in a desk lamp or ceiling fixture. IEEE Senior Member Harald Haas has developed a visible light communication system he calls light fidelity, or Li-Fi, which relies on nanometer waves in...

  • Why AT&T Tried to Kill the Answering Machine

    If you follow the history of the answering machine it spans more than 100 years with a variety of formats and recording media. The process began in the late 1800’s with Valdemar Pouisen who invented the first device to record sound through magnetics and wire. This device was known as the telegraphone and it paved...
