European UWB Regulation Background
May 2003
Two Groups with Primary responsibility
CEPT SE24
European Conference of Postal and Telecommunications Administrations Spectrum Engineering Committee 24
Currently studying UWB frequency sharing with other services in bands < 6 GHz
Results will guide European regulators
Provides European input to ITU-R TG 1/8
ETSI TG31a
Focusing on conformance testing

4. The European Process ETSI TG31a Uses FCC mask as starting point
May 2003
The European Process
ETSI TG31a
Uses FCC mask as starting point
Adds sloping sides for O.O.B. emissions
CEPT SE24
Uses FCC mask as starting point
For in-band sharing studies
OOB – Out of band

CEPT SE24 Current (draft) Report – Point 1
Protection for Fixed Service < 6 GHz
In the bands: GHz, GHz and GHz
Fix at some 20 dB below FCC emission mask
Agree with FCC limit: 3.1 to 3.41 GHz and 4.2 to 4.4 GHz
Fixed Service results are only one example
These results to will go to ITU-R TG 1/8 through European contributions
Observation: allowable bandwidth can not support UWB under the FCC definition

CEPT SE24 Current (draft) Report – Point 1
More observations:
Global deployment of single emission mask and single standard UWB needs attention
Calculations are difficult to fault
Assumptions should be reviewed
Some companies are active: more help is needed!!

ETSI TG31a UWB mask – Point 2
Sloping ETSI mask should be examined
No lower limit for out-of-band emission
Is the slope comfortable for implementation?

ETSI TG31a – Conformance testing
Should be reviewed by industry
Completion of work may be waiting for a to decide non modulation and waveforms
