  1. Ultra Wideband Technology T-109.551 Research Seminar on Telecommunications Business II Haapaniemi, Isola: UWB

  2. PAN Device networks < 10 m Bluetooth WLAN Computer networks Indoor < 60 m Outdoor < 200 m IEEE 802.11 a/b/g/h HiperLAN2 TCP/IP Segmentation of Wireless Solutions 1/2 Haapaniemi, Isola: UWB

  3. Ultra Wideband OFDM Bluetooth HiperLAN2 IEEE 802.11 a/b/g/h UMTS Segmentation of Wireless Solutions 2/2 vs. Haapaniemi, Isola: UWB

  4. Introduction to UWB 1/4 - Technology - • Extremely short pulses in the time domain • Large bandwidth in the frequency domain • Fractional bandwidth=(fH-fL)/fC> 25% • or total bandwidth > 1,5 GHz F Amplitude Amplitude S frequency / Hz time / s B Haapaniemi, Isola: UWB

  5. Introduction to UWB 2/4 - Technology- PROS • High data rates • Low transmission power • Multipath immunity • Simple implementation, low cost • CONS • Short operating ranges • Interference with other licensed, ”narrowband” systems Haapaniemi, Isola: UWB

  6. Introduction to UWB 3/4 - Regulations - • FCC approved the sale of UWB products in the United States under certain limits in February 2002 • UWB devices are allowed to work on very low power levels to avoid interference • ETSI is working on proposal in Europe Haapaniemi, Isola: UWB

  7. Introduction to UWB 4/4 - Applications - • Automotive collision-detection systems • Medical imaging • Through-wall imaging • Ground-penetrating radar • Communications devices • Cable replacement (USB, Firewire) Haapaniemi, Isola: UWB

  8. Companies • Xtreme Spectrum (Trinity chipset) • Philips (chipsets for IEEE 802.15.3a) • Mitsubishi Electric (development of UWB channel model) • Cisco, Intel and Motorola Haapaniemi, Isola: UWB

  9. Complementing and Competing Technologies • GSM, GPRS, EDGE and UMTS are complementing due to their superior mobility compared to others • Wired solutions are always required as backbones • Most probable competitors are Bluetooth, IEEE 802.11 and HiperLAN2 Haapaniemi, Isola: UWB

  10. Three Scenarios 1/3 • PAN: Bluetooth • WLAN: IEEE 802.11 • UWB gains popularity in small segments like automobile collision detection and wall-through radars  UWB remains as marginal technology Haapaniemi, Isola: UWB

  11. Three Scenarios 2/3 • PAN: UWB replaces Bluetooth • WLAN: UWB and IEEE 802.11 co-exist • Transition to HDTV in USA opens totally new market that benefits UWB. CATV operators exploit this opportunity.  UWB is widely used where it is best Haapaniemi, Isola: UWB

  12. Three Scenarios 3/3 • PAN: UWB replaces Bluetooth • WLAN: UWB replaces IEEE 802.11 • Integration with IEEE 802.3 framing and IP succeeds. New product that combine mobile networks and UWB hit the market.  UWB becomes a major solution for short range wireless services Haapaniemi, Isola: UWB

  13. Market Estimates Haapaniemi, Isola: UWB
