    UWB Radio - High data rate wireless radiosystems with Real time location support

    The technology achieves sufficient accuracy in distance measurementand in real time positioning. During the distance measurement andpositioning the UWB technology provides simultaneous wireless datatransmission up to 6.8 Mbit/s.The UWB radio technology has been applied in different applicationssuch as short-range communication, sensor networks systems and realtime location systems (RTLS).The UWB radio signals have an extremely wide bandwidth comparedto traditional radio signals, which offers several benefits; accurateranging, robustness to propagation fading, superior obstaclepenetration, resistance to jamming, interference rejection, and fluentcoexistence with traditional narrow bandwidth systems.

    UWB basics

    Relatively immune todisturbances.Doesnt disturb conventionalradio transmitters (powerlevel ca. 1 mW).Operational distance up to300 meters in open space.Very broad signal bandwidth,typically > 500 MHz.

    Basics of Impulse Radar technology

    Utilises UWB bands3,1 10,6 GHz

    Very low energy radiation-41,3 dBm/MHz

    Relatively economic solution.One chip only.No moving parts.Measures only flying timee.g. distance, introducingdirection of measuredobjects need more antennas.A transmitter antenna is emitting veryshort non-sinusoidal pulses.

    Transmitted signals bandwidth is severalgigahertzes.

    Ultra-Wideband Radio

    Methods, like imaging, laser-scanners, radars arecumbersome and not at all ideal solutions to theneeds.

    Typically soft objects (humans, animals) are notvisible to todays car-radars.

    Operation in challenging environments (dust, rain,smoke).

    Economics, implementations are far cheaper thancompeting ones.

    Technology benefitsImmune to radio disturbances and signal fadingDoesnt disturb conventional radio transmitters(power level ca. 1 mW).Operational distance < 100 meters.Very broad signal bandwidth, typically > 500 MHz.Very fast pulses -> great accuracy in positioningapplications.

    Technology usage2D and 3D real-time positioning systems (RTLS)Positioning of humans in factories, warehouses etcDistance measurements, cylinders etc.Fast data transmission (->6,8 Mbit/s) in harsh env.Combined positioning and data transmission
