Terms of Reference for TC ERM Working Group (WG) UWB: Ultra Wide Band (UWB)

Approved at ERM #87b

1           Tasks:

The task of TC ERM WG UWB is to investigate and develop generic and specific ETSI radio standards for Short Range Devices (SRD) using broadband air interfaces and systems using Ultra Wide Band (UWB) technologies under the direction of TC ERM, for communications purposes, sensor applications and networks. In addition, TC ERM WG UWB will identify spectrum requirements to ensure spectrum efficiency and compatibility with other radio services in co-operation with TC ERM according to its Terms of Reference and working procedures.

The main objectives of TC ERM WG UWB are:

• Investigate and develop generic and specific ETSI radio standards for Short Range Devices using broadband air interfaces and systems using Ultra Wide Band (UWB) technologies;


• Identify spectrum requirements for SRD devices using UWB/broadband technology;


• Support administrations during the discussions on the permanent EC mandates to CEPT ECC on UWB (UWB operating below 10,6 GHz) and SRD (for SRD operating above 40 GHz and specific wideband devices)

2           Areas of activity:

The activities of TC ERM WG UWB are linked with the regulatory EC/ECC framework for:

UWB devices operating below 10,6 GHz which are covered by

• ECC/DEC/(06)04; UWB operating below 10,6 GHz;


• ECC/DEC/(07)01; UWB material sensing (also listed in ERC/REC/70-03 Annex 6);


• ECC/DEC/(12)03; UWB onboard aircraft;


• ECC/REC/(11)09; Location tracking type 2 (also listed in ERC/REC/70-03 Annex 6);


• ECC/REC/(11)10; Location tracking application for emergency and disaster situations;


• Related European Commission Decision on UWB.

NOTE: These rules and related ETSI work is covered by the European Commission (EC) permanent mandate to CEPT on UWB.

Generic SRD operating above the frequency of 40 GHz which are covered by

• ERC/REC/70-03 Annex 1 (band n1, n2, o1, o2, p) and related EC SRD Decision (2022/180/EU) (band 74a, 76, 80a, 80b, 81);


• ECC/DEC/(22)03 and new EC Decision for radiodetermination applications above 116 GHz (also listed in ERC/REC/70-03 Annex 6).

NOTE: These rules and related ETSI work is covered by the EC permanent mandate to CEPT on SRD.

Specific wideband SRDs which are covered by

• ECC/DEC/(11)02; Level probing radar;


• ERC/REC/70-03 Annex 6 (band f1, f2, f3, f4, f5) and related EC SRD Decision (2022/180/EU) (band 60, 64, 68, 74b, 78b); (Tank) level probing radar;


• ECC/DEC/(06)08 (also listed in ERC/REC/70-03 Annex 6); Ground and wall probing radar;


• ECC/DEC/(21)02 (also listed in ERC/REC/70-03 Annex 6 (band l)) and related EC SRD Decision (2022/180/EU) (band 65); (High definition) ground based synthetic aperture radar;


• ERC/REC/70-03 Annex 6 and new EC SRD Decision for security scanners.

NOTE: These rules and related ETSI work is covered by the EC permanent mandate to CEPT on SRD.

3           Remarks

Liaisons will be established with bodies both internal to ETSI (e,g, TC ERM WG SRR) and external to ETSI (e.g. CEPT ECC WG FM PT SRD-MG, CEPT ECC WG SE PT SE24) on matters relevant for the development of ultra-wideband wireless short range applications in accordance with TC ERM working procedures.

Horizontal aspects related to EMC and radio spectrum matters will be deferred to TC ERM WG EMC and TC ERM WG RM respectively.

TC ERM WG UWB will establish liaisons with ETSI Technical Groups and other TC ERM WGs dealing with Short Range Devices using (ultra) wideband wireless interfaces.
