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
