LEDs Transfer Optical Data to Mobile Devices

Facebook X LinkedIn Email
MUNICH, Germany, Aug. 2, 2011 — Common room-illuminating LEDs are now being used to transport HD video from the Internet directly to laptops and other mobile devices. With only a few adjustments, regular LEDs are being turned into optical WLANs — safely shuttling high-speed data wirelessly and with no loss in quality. Within the scope of the EU's OMEGA project (the Home Gigabit Access project, consisting of 20 European partners from industry and academia), scientists from the Fraunhofer Institute for Telecommunications, Heinrich Hertz Institute (HHI) in Berlin, in collaboration with industry partners Siemens and...Read full article

    photodiode
    A two-electrode, radiation-sensitive junction formed in a semiconductor material in which the reverse current varies with illumination. Photodiodes are used for the detection of optical power and for the conversion of optical power to electrical power. See avalanche photodiode; PIN photodiode.
    siemens
    The electric conductance of a conductor in which a current of 1 ampere is produced by an electric potential difference of 1 volt.
