What is UWB?

• First of all, the term "ultra wideband" is a
  relatively new term to describe a technology
  which had been known since the early 1960s as
  "carrier-free", "baseband" or "impulse"
  technology. The basic concept is to develop,
  transmit and receive an extremely short duration
  burst of radio frequency (RF) energy typically
  a few tens of picoseconds (trillionths of a
  second) to a few nanoseconds (billionths of a
  second) in duration.
• Frequency range occupied is more than 500 MHz or
  fractional bandwidth is greater than 20.

Advantages of UWB

• High Data rates
• Low Power
• Immunity to multipaths
• No carrier
• Low cost transceivers
• Bandwidth usually in GHz
• Promising applications in Biomedical areas

4
Applications

• Cardiac Monitoring and Imaging
• Respiratory pattern monitor
• Infant Monitor
• Vocal Chord Monitor
• Wheel Chair Driving systems
• Smart Home systems
• Rubble Rescue Radar
• IR Spectral Imagingetc etc

5
Advantages

• Non Contact Based
• No Cleaning required
• No disposables
• Remote and Continuous monitors
• Low Cost
• Low Maintenance
• Can monitor through clothes and useful at a few
  meters range
