Introduction
The present document is part of a set of standards developed by ETSI and is designed to fit in a modular structure to
cover all radio and telecommunications terminal equipment within the scope of the Directive 2014/53/EU [i.3].
For the case of the present document, the applicable harmonised standard has been ETSI EN 302 065-4 (V1.1.1) [i.8],
for Material Sensing devices using UWB technology below 10,6 GHz which was published in the OJEU without
restriction at 12 April 2017.
In order to consider the above points, ETSI ERM TGUWB decided to develop more specific standards; this means
instead of one generic ETSI EN 302 065-4 [i.8] standard for Material Sensing devices the following standard family
ETSI EN 302 065-4-x for material sensing devices:
• ETSI EN 302 065-4-1: "Material Sensing devices; Sub-part 1: Building material analysis below 10,6 GHz".
• ETSI EN 302 065-4-2: "UWB Material Sensing devices for Security Scanning".
• ETSI EN 302 065-4-3: "Ground humidity and condition sensor".
• ETSI EN 302 065-4-4: "Material Sensing devices; Sub-part 4: Exterior material sensing applications for
ground based vehicles".
• ETSI EN 302 065-4-5: "UWB surveillance devices for parking lot sensors below 10,6 GHz".
NOTE: The above list of standards represents the active work items at the time of finalizing the present document
and the final structure of the ETSI EN 302 065-4-x family may change later.

4.2 EUT categories
4.2.1 General
The present document covers one category of EUT for exterior material sensing applications at ground based vehicle
below 10,6 GHz. This category is named as Exterior Vehicle Sensors (EVSs).
More details about the use-case, wanted technical performance criteria and the RX-test conditions of the EVS category
is provided in annex C.
The specified EVS EUT sub-categories provide a clear classification for the wanted technical performance criteria,
limits requirements and conformance test procedures.
The following criteria were considered for sub-categorization of EVS category:
• Regulation: ECC and EC recommendations and decisions, see clause 4.2.2.
• Modulation: kind of modulation of the TX signal, see clause 4.2.3.
• Usage of active UWB mitigation techniques (e.g. LBT, DAA), see clause 4.2.4.
An overview of the EVS EUT sub-categories is provided in clause 4.2.5, table 1.
4.2.2 Categorization by Regulation
The following regulation was considered for sub-categorization of EVS EUT:
• UWB regulations: ECC/DEC/(07)01 [i.1] and 2019/785/EU [i.2] for EVS EUT based on UWB technology
with or without active mitigation techniques.
4.2.3 Categorization by Modulation
The following categorization of EVS EUT by modulation is used:
• TX1: for EUT with FHSS, sequential hopping/stepping or FMCW modulation.
• TX2: for any other modulation different from TX1.
4.2.4 Categorization by Active Mitigation Techniques
BMA EUT covered by ECC/DEC/(07)01 [i.1] and 2019/785/EU [i.2] can be categorized by use of active mitigation
techniques (e.g. Listen Before Transmit (LBT), Detect-and-Avoid (DAA)):
• EVS EUT based on UWB technology without active mitigation techniques.
• EVS EUT based on UWB technology with active mitigation techniques.
ETSI

Introduction
The present document is part of a set of standards developed by ETSI and is designed to fit in a modular structure to
cover all radio and telecommunications terminal equipment within the scope of the Directive 2014/53/EU [i.3].
For the case of the present document, the applicable harmonised standard has been ETSI EN 302 065-4 (V1.1.1) [i.8],
for Material Sensing devices using UWB technology below 10,6 GHz which was published in the OJEU without
restriction at 12 April 2017.
In order to consider the above points, ETSI ERM TGUWB decided to develop more specific standards; this means
instead of one generic ETSI EN 302 065-4 [i.8] standard for Material Sensing devices the following standard family
ETSI EN 302 065-4-x for material sensing devices:
• ETSI EN 302 065-4-1: "Material Sensing devices; Sub-part 1: Building material analysis below 10,6 GHz".
• ETSI EN 302 065-4-2: "UWB Material Sensing devices for Security Scanning".
• ETSI EN 302 065-4-3: "Ground humidity and condition sensor".
• ETSI EN 302 065-4-4: "Material Sensing devices; Sub-part 4: Exterior material sensing applications for
ground based vehicles".
• ETSI EN 302 065-4-5: "UWB surveillance devices for parking lot sensors below 10,6 GHz".
NOTE: The above list of standards represents the active work items at the time of finalizing the present document
and the final structure of the ETSI EN 302 065-4-x family may change later.

4 Technical requirements specifications
4.1 Environmental profile
The technical requirements of the present document apply under the environmental profile for operation of the
equipment, which shall be in accordance with its intended use. The equipment shall comply with all the technical
requirements of the present document at all times when operating within the boundary limits of the operational
environmental profile defined by its intended use.
4.2 EUT categories
4.2.1 General
The present document covers one category of EUT for exterior material sensing applications at ground based vehicle
below 10,6 GHz. This category is named as Exterior Vehicle Sensors (EVSs).
More details about the use-case, wanted technical performance criteria and the RX-test conditions of the EVS category
is provided in annex C.
The specified EVS EUT sub-categories provide a clear classification for the wanted technical performance criteria,
limits requirements and conformance test procedures.
The following criteria were considered for sub-categorization of EVS category:
• Regulation: ECC and EC recommendations and decisions, see clause 4.2.2.
• Modulation: kind of modulation of the TX signal, see clause 4.2.3.
• Usage of active UWB mitigation techniques (e.g. LBT, DAA), see clause 4.2.4.
An overview of the EVS EUT sub-categories is provided in clause 4.2.5, table 1.
4.2.2 Categorization by Regulation
The following regulation was considered for sub-categorization of EVS EUT:
• UWB regulations: ECC/DEC/(07)01 [i.1] and 2019/785/EU [i.2] for EVS EUT based on UWB technology
with or without active mitigation techniques.
4.2.3 Categorization by Modulation
The following categorization of EVS EUT by modulation is used:
• TX1: for EUT with FHSS, sequential hopping/stepping or FMCW modulation.
• TX2: for any other modulation different from TX1.
4.2.4 Categorization by Active Mitigation Techniques
BMA EUT covered by ECC/DEC/(07)01 [i.1] and 2019/785/EU [i.2] can be categorized by use of active mitigation
techniques (e.g. Listen Before Transmit (LBT), Detect-and-Avoid (DAA)):
• EVS EUT based on UWB technology without active mitigation techniques.
• EVS EUT based on UWB technology with active mitigation techniques.
ETSI
12 ETSI EN 302 065-4-4 V1.1.1 (2022-06)
4.2.5 Summary EVS EUT sub-categories
4 sub-categories of the EVS EUT are identified:
• EVS1: based on UWB technology without active mitigation techniques using TX1 (UWB regulations)
• EVS2: based on UWB technology without active mitigation techniques using TX2 (UWB regulations)
• EVS3: based on UWB technology with active mitigation techniques using TX1 (UWB regulations)
• EVS4: based on UWB technology with active mitigation techniques using TX2 (UWB regulations)
An overview of requirements for each EVS EUT sub-categories is given in table 1.
