>200 Mb/s

< 10 m

< 100 m ~1 Mb/s



100‘s Mb/s over short-range links (up to ~10m) High data rate video to flat screens, transfer of still

images from digital camera to PC 10‘s kb/s to ~1 Mb/s over links (up to 100 m)

Warehousing, rescue (e.g. fire brigades), tracking of sensitive goods, industrial production processes

UWB Radio Potential (Markets)

UWB suitable for high number of appliances

Indoor (home, office, workplace, stores...) + outdoor

Can serve low to high-end markets

Low cost: e.g. RFID, positioning, sensor networks

High performance : e.g. high rate video data, wireless WWW access, mobile computing

Convergence synergies

Operation Principles (“Spectrum Underlay“)

1 Frequency/GHz 10

Narrowband (e.g GSM: +35 dBm/MHz)

WCDMA (typ. +15 dBm/MHz)

UWB (e.g – 41 dBm/MHz)

4

Transmit Power

Spectral Density

[dBm/MHz]

Bandwidth (GSM : WCDMA : UWB) ~ 1 : 10 : 10000



Operation Principles (Major Advantages)

Access to a huge license-free spectrum resource

Decentralised use of spectrum by high number

of UWB devices

High spatial capacity (100s Mb/s in room/office)

Low max. RF output power (< 0.6 mW in US)

low radiation hazard

Supports maximisation of spectrum usage

5



Operation Principles (Incumbents‘ Concern)

Potentially affected radio services in: Mobile communications Fixed wireless access Satellite communications Air traffic control Global positioning Scientific radio research

UWB UBIQUITY

Status of Research & Development

< 2000 Military applications (US start-ups)

~2000 International interest (Far East/Europe)

Major manufacturers get invested in UWB

2001 European UWB projects (IST)

whyless.com (FP5, UWB-WLAN, spectrum management study)

UCAN (FP5, UWB high data rate system development)

ULTRAWAVES (FP5, UWB system for multiple video streams)

PACWOMAN/URSAFE (FP5, low power PAN, medical appl.)

2003 250 Mb/s over short links demonstrated

2004 PULSERS (FP6, builds on and extends FP5 UWB

projects) 7



Status of Research & Development (Europe)

UWB research in Europe

Closing up to US and Japan

Dedicated and efficient research community

Considerable visibility in international scientific, regulation and standardisation activities

Practical implementations/experience

Not encouraged by pending regulatory processes

Hampered by non-existent initial/experimental deployment permits

8



Status of Regulation (US)

Federal Communications Commission (FCC)

UWB regulation effective February 2002

“Start from conservative basis“

Reiterations dependent on market experience

• initial ruling confirmed February 2003 Spectrum masks (e.g. –41.3 dBm/MHz from 3.1 – 10.6 GHz)

Indoor: fixed UWB infrastructure

Outdoor: only mobile UWB devices

UWB operation possible below 1 GHz

9



Status of Regulation (ASIA)

Japan Studies initiated by MPHPT in 2002 ICT Sub-Council report

• Positive as regards coexistence• Cautious approach advised

Regulation expected in 2005 Experimental deployment in 2004?

Singapore IDA proactively drives UWB UWB friendly zone established in 2003 allowing 4 times FCC power spectral density

10



Status of Regulation (Europe)

ETSI mandated (M/329) by EC DG Enterprise in 2003 to produce harmonised UWB standard

Request to establish a set of Harmonised Standardscovering UWB applications under Directive 1999/5/EC

Ongoing coexistence studies : CEPT (SE24)

Contradictory study results (pro vs con)

No jointly accepted interference models/definitions

No experimental verification planned

Process currently appears “deadlocked“

Reason for our being here today!

11



UWB Cluster Recommendations

RSC is invited to encourage...

Continuation of open & transparent European UWB regulation process

Adequate protection of established spectrum users and radio services

Global compatibility of UWB regulation

Convergence towards jointly accepted interference models/thresholds

Incremental (low risk) regulation process with early trial phase preceding open UWB market

12



Contribute to:

Interference models, -scenarios, -definitions, ... by providing critical mass of expertise

Setting-up effective UWB trial framework

• Providing UWB technologies & technical

skills

• Conducting measurements/field trials

• Evaluation & reporting of relevant results

UWB Cluster – Proposed Role

THANK YOU!

The UWB Cluster invites the RSC to provide guidance on how to go forward in a most

constructive manner
