Title: Ultra Wideband Technology


1
Ultra Wideband Technology
  • T-109.551 Research Seminar on Telecommunications
    Business II

2
Segmentation of Wireless Solutions 1/2
  • PAN
  • Device networks
  • lt 10 m
  • Bluetooth
  • WLAN
  • Computer networks
  • Indoor lt 60 m
  • Outdoor lt 200 m
  • IEEE 802.11 a/b/g/h
  • HiperLAN2
  • TCP/IP

3
Segmentation of Wireless Solutions 2/2
vs.
  • Ultra Wideband
  • OFDM
  • Bluetooth
  • HiperLAN2
  • IEEE 802.11 a/b/g/h
  • UMTS

4
Introduction to UWB 1/4
- Technology -
  • Extremely short pulses in the time domain
  • Large bandwidth in the frequency domain
  • Fractional bandwidth(fH-fL)/fCgt 25
  • or total bandwidth gt 1,5 GHz

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

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

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)

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

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

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

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

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
