    Introduction
    • Ultra - wideband  is a radio technology that
    can be used at very low energy levels for
    short-range high-bandwidth communications by
    using a large portion of the radio spectrum.
    •  Technology for transmitting information
    spread over a large bandwidth (>500 MHz) that
    should, in theory and under the right
    circumstances, be able to share spectrum with
    other users.

    Working
    Ø A UWB transmitter works by sending billions of
    pulses across a very wide spectrum of
    frequency several GHz in bandwidth.
    Ø The corresponding receiver then translates the
    pulses into data by listening for a familiar
    pulse sequence sent by the transmitter.

    Pros
    • High data capacity .
    – Can support close to 30,000 users at 19.2kbps with BER
    of 10 or a 6 users system with a peak speed of
    -3
    50mbps.
    • Low power .
    – Transmitting at microwatts results in very low harmful
    interference to other radio systems. Usually below
    the noise floor and undetectable.
    – Longer battery life for mobile devices.
    • Resilient to distortions and fading ( Great for
    indoor usage ).
    – Spread spectrum property overcomes frequency selective
    fading.
    – High information redundancy and frequency diversity
    provides protection against multi-path distortion.
    • Simplicity translate to lower hardware cost .
    – No carrier frequency translate analog front-end has
    simpler implementation than traditional
    sinusoidal radio.
    • Security
    – Only a receiver that knows the schedule of the 8, CUSA
    School of Engineering
    Cons
    • Interference with GPS .
    – UWB presents a problem to GPS because their
    frequency overlaps, and GPS signal is particular
    sensitive to interference .
    • Limited on range
    – Output power is limited in order to keep down the
    noise floor due to its overlapping frequency
    bandwidth with other radio systems.
    • One kilometer with high gain antenna.
    • Ten to twenty meter with regular antenna.
    • Affects on economy and current businesses .
    – Speculations on UWB making current billion
    dollar FCC licensed frequencies worthless.
    – Increased competition for local cable or phone
    company. Making their existent investments
    on cable and equipments obsolete.

    Conclusion

    • In today's era of mobile communication UWB


    technology is next step toward it as it
    provides a wide bandwidth, low cost and
    low power consumption for the need of
    mobile communication as try to remove the
    barrier in the way to wireless
    communication.
    • So its next step toward the funda of mobile
    communication i.e. Anything , Anywhere ,
    Anytime .
