  2. 2.  What is UWB?  Principles of UWB  Advantages of UWB  Applications of UWB  UWB Characteristics  Comparison With Other Technologies  Future Scopes  Challenges  Conclusion  References
  3. 3.   Wireless technology for transmitting digital data at very high rates, using very low power. UWB is ideally suited for short-range and high-speed data transmissions for WPAN applications.
  4. 4. Time Domain • Extremely short pulses • Very low duty cycle Frequency Domain • Ultra wide spectrum • Low power spectral density
  5. 5. Spectrum reuse High data rate in short range Multipath immunity • 3.1-10.6 GHz, coexist with other users • 500 Mbps at 10 feet • Path delay >> pulse width Low power • Baseband modulation (no carrier) Low cost • Almost “all digital”, simple analog module
  6. 6. Communications Radar Intelligence Sensors • Wireless Personal Area Network • Military communications • Ground penetrating radar • Through-wall radar • Buried victim rescue • Telemetry • Intelligent airbag, driving and parking aids • Intelligent transport system
  7. 7.   Due to the wide bandwidth and high time resolution UWB signals are much more robust to interferences and multipath fading. The large channel capacity and wide bandwidth offer wireless transmission of real-time high quality multimedia files.
  8. 8.  The extremely small transmit power and the very short communication distances result in a large number of other advantages for WPAN applications.  Since UWB signals are operating below the noise floor, they provide better security, lower RF health hazards, and lower interference to other systems
  9. 9.  Ground   o penetrating radar (GPR):- Because of Accurate timing information and ultra wide bandwidth it is widely applicable for the detection of unknown objects under the ground. The UWB GPR is used to draw a map of gas pipelines buried under ground by connecting GPS system to the GPR UWB GPR have been intensively investigated for mine detection.
  10. 10.  Military  o Communication :- Attractive for manned and unmanned military vehicles 􀂉 Issues associated with cable weight, space, and costs. 􀂉 Substantial cost associated with installing and modifying cabling embedded within the platform . Trade-off: extra ammunition or fuel.
  11. 11.  Extremely low transmission energy  Extremely difficult to intercept  Multipath immunity to fading  Follows Shannon’s channel capacity theorem  C:- Maximum channel capacity B:- Bandwidth(Hz) S/N:- Signal to Noise power Ratio(Watts)  
  12. 12. COMPARISION WITH OTHER TECHNOLOGIES • Extremely low transmission energy • Extremely difficult to intercept • Multipath immunity to fading • Follows Shannon’s channel capacity theorem
  13. 13. WIRELESS USB   The next step for USB technology is wireless USB. WUSB will be high speed wireless interconnect technology to take advantage of UWB  With WUSB, a user can bring a hard disk in proximity to a PC, laptop and, once authentication and authorization are complete, files can be transferred onto the PC.
  14. 14.  Interference  Tradeoffs  Low with other licensed bands with noise power operation
  15. 15.  Well suited for high speed, short range WPAN.  Supports multimedia data rates, and offers inherent data security.  There's a possibility that UWB will become the "next best" technology for all types of wireless networks, including wireless LANs.
