What is Time Modulated Ultra Wideband Wireless
(TM-UWB) ?

• A New Wireless Paradigm

Very Different Historical Analogies

• Going from Vacuum Tubes to Transistors

• Going from Analog to Digital

• Going from Circuit Switching to Packet
  Switching

16
Technology Fundamentals of TM-UWB
Very different from conventional RF

• No continuous sine waves

• No assigned frequency

• No resonance

• No power amplifiers

• Multipath is a friend, not an enemy

17
Technology Fundamentals of TM-UWB

• Millions of Distinct Pulses per Second, Not a
  Continuous Sinewave

• Pulse Position
• Modulation for
• Data Encoding

• Time Hopped
• Channel Coding
• to Appear as
• Random Noise

18
What is UWBs Role in the Future of Broadband
Wireless?
Broadband To The Home...
Optical
DSL
Satellite
Cable Modem
FTTH
MMDS
CATV
POTS
The Challenge Broadband thru the home
19
Obstacles to Home Broadband Wireless - US

• Standards

• Incompatibility of Technologies

• The Spectrum Drought

• Licensed bands

• Unlicensed bands (2.4 Ghz UNII)

20
Unlicensed Spectrum-US
2.4 GHz 100 MHz
UNII Bands 300 MHz
21
Broadband Mobile Wireless - US
Two Challenges to Mobile Phone Industry

• Running out of spectrum

• Consumer health concerns

The UWB/PulsON Solution Dual-mode phone

• Outdoors expensive spectrum infrastructure at
  high power

• Indoors unlicensed spectrum at ultra-low power
  50 microwatts

22
Benefits of UWB
Ultra High Bandwidth Per User
Low Cost Interoperability
Channelization- Highly Efficient Use Of Spectrum
Fused Capability Inherent Radar Tracking
Ultra Low Power
Robust Indoor Performance
Private Inherently Encrypted

• Potential to Createmany GHz of New
  spectrum

• Non-interfering basis

• Reduce demand on government spectrum
  owners

• Frees up outdoor spectrum via dual-mode
  indoor/outdoor phones

29
Regulatory Status of UWB in USA

• Notice of Inquiry Sept 1998

• Military/Public Safety waivers - June 1999

• Notice of Proposed Rulemaking - May 2000

• Ultra wideband is a promising,
• spectrum efficient (wireless)
• technology that could provide
• tremendous benefits for public safety
• and for persons seeking broadband
• Internet access.
• W. Kennard, May 10, 2000

William E. Kennard FCC Chairman
31

• ultra wideband is considered by those who know
• about it to be the answer to just about every
• communications technology issue today.
• Upside Today, May 16, 2000

32

• It holds the promise of dramatically reducing
  the
• pressure on the wireless spectrum
• CNET, May 11, 2000

33

• This appears to be a
• truly unique technology
• promises important
• new products limited only by the imagination.

35
Regulatory Status of UWB in USA the specifics

• Presently billion of unintentional UWB devices
  approved (laptops, PDAs, etc).

• Operate in Part 15 license exempt

• Requirements
• Thou shalt not create harmful interference

• Unintentional UWB devices can use commercial
  and government spectrum

• Intentional UWB devices can use commercial
  spectrum, but not Government spectrum

• Seminal Question Does the intent of a signal
• change its interference potential?

36
Regulatory Status of UWB in USA - Testing

• GPS testing DoT, NTIA, University of Texas

• PCS testing Sprint Time Domain

• All tests due October 30th

• Our preliminary conclusion intent does
• not matter

37
Reaction.

• The Public Return from ultra-wideband radio will
  be seen in the creation of new industries,
  improved worker productivity, lower inventories,
  better public safety systems, and better use of
  the Nations Information Infrastructure. we see
  ultra wideband as a potential game changer
  for our company, and the productivity of the
  nation.
• GE Corporate Research and Development

38

• UWB is a key enabling technology which makes
  high quality, high data rate wireless
  communications possible in heavily congested
  communications environment.
• Sony Corporation

39

• the fact thatUWB would not require licensed
  operation, nor would it require coordination with
  other unlicensed users of UWB products, would
  greatly facilitate and accelerate the
  marketability and attractiveness of these
  products.
