Introduction
ETSI ERM TGUWB decided to develop more specific standards; this means instead of one generic ETSI
EN 302 729 [i.13] for all Level Probing Radar (LPR) devices, a multi-part deliverable was initiated in order to reflect
the intended use in relation to different aspects of the corresponding regulation ECC Decision (11)02 [i.3].
Part 1 of the multi-part deliverable covers the original provisions made in ECC Decision (11)02 [i.3] of 11 March 2011
for LPR equipment with strictly vertical downward installation (see ECC Decision (11)02 [i.3], first four lines of
Table 1 for strictly vertical antenna orientation).
Part 2 of the multi-part deliverable covers the amendments made in ECC Decision (11)02 [i.3] on 5 July 2019 for LPR
equipment with tilted downward installation (see ECC Decision (11)02 [i.3], last three lines of Table 1 for tilted antenna
orientation).
Due to the amendment of ECC Decision (11)02 [i.3] on 5 July 2019, ETSI ERM TGUWB decided to follow henceforth
a two part structure and to only reflect the amendments made in 2019 in part 2 of the series.
More information on the conducted changes in previous versions of the present document can be found in the change
history in Annex H.

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, but as a minimum, shall be that specified in the test
conditions contained in the present document. 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
Technical and regulatory requirements for Level Probing Radars are provided in general in European
Commission Implementing Decision (EU) 2022/180 [i.7] and ECC Decision (11)02 [i.3], which are based on ECC
Report 139 [i.4]. The present document covers only the essential technical requirements set out in the first four rows in
Table 1 of ECC Decision (11)02 [i.3] for LPR equipment using a strictly vertical downward orientation of the EUT
antenna.
In addition, the manufacturer needs to consider further installation requirements as specified in Annex E and will have
to provide this information to the user/installer. These installation requirements, however, are not subject to Annex A of
the present document.
Receive-only devices, EUTs exhibiting a receive only mode or a standby mode are not covered by the scope of the
present document.
A further sub-categorization of this LPR device category has been conducted based on:
• the output power, see clause 4.2.2;
• the used Operating Frequency Range (OFR), see clause 4.2.3;
• the used antenna connection, see clause 4.2.4.
The environmental conditions for testing are specified in clause 5.1.
4.2.2 Categorization by output power
The following sub-categorization of LPR EUTs by the output power is used:
• LP1: EUT is a low power LPR (LPLPR) device;
• LP2: EUT is a high power LPR (HPLPR) device.
More information on LP1 and LP2 devices can be found in clause 4.3.7.1.
NOTE: The LP1 category considers a reduced mean and peak power limit by 20 dB compared to ECC
Decision (11)02 [i.3]. This reduction of transmit power is equivalent to the use of a mitigation technique
as described in clause 4.3.7 and therefore no additional mitigation measures are necessary for the LP1
category.
4.2.3 Categorization by Operating Frequency Range (OFR)
The following sub-categorization of LPR EUTs by the operating frequency range is used:
• OFR1: OFR of the EUT is contained in the frequency range 6 GHz to 8,5 GHz;
• OFR2: OFR of the EUT is contained in the frequency range 24,05 GHz to 26,5 GHz;

• OFR3: OFR of the EUT is contained in the frequency range 57 GHz to 64 GHz;
• OFR4: OFR of the EUT is contained in the frequency range 75 GHz to 85 GHz.
This categorization has been conducted, reflecting the different permitted frequency ranges which can be used for Level
Probing Radars in accordance with European Commission Implementing Decision (EU) 2022/180 [i.7] and ECC
Decision (11)02 [i.3].
4.2.4 Categorization by antenna connection
The following sub-categorization of LPR EUTs by the antenna connection is used:
• ANT1: EUT features an antenna connector, e.g. the EUT is equipped with a dedicated antenna;
• ANT2: EUT has no antenna connector, e.g. the EUT is equipped with an integral antenna.
4.2.5 Summary of LPR sub-categories
An overview of the applicability of transmitter requirements and receiver requirements for the different LPR
sub-categories is shown in Table 1 and Table 2, respectively.

Introduction
ETSI ERM TGUWB decided to develop more specific standards; this means instead of one generic ETSI
EN 302 729 [i.13] for all Level Probing Radar (LPR) devices, a multi-part deliverable was initiated in order to reflect
the intended use in relation to different aspects of the corresponding regulation ECC Decision (11)02 [i.3].
Part 1 of the multi-part deliverable covers the original provisions made in ECC Decision (11)02 [i.3] of 11 March 2011
for LPR equipment with strictly vertical downward installation (see ECC Decision (11)02 [i.3], first four lines of
Table 1 for strictly vertical antenna orientation).
Part 2 of the multi-part deliverable covers the amendments made in ECC Decision (11)02 [i.3] on 5 July 2019 for LPR
equipment with tilted downward installation (see ECC Decision (11)02 [i.3], last three lines of Table 1 for tilted antenna
orientation).
Due to the amendment of ECC Decision (11)02 [i.3] on 5 July 2019, ETSI ERM TGUWB decided to follow henceforth
a two part structure and to only reflect the amendments made in 2019 in part 2 of the series.
More information on the conducted changes in previous versions of the present document can be found in the change
history in Annex H.

4.2 EUT categories
4.2.1 General
Technical and regulatory requirements for Level Probing Radars are provided in general in European
Commission Implementing Decision (EU) 2022/180 [i.7] and ECC Decision (11)02 [i.3], which are based on ECC
Report 139 [i.4]. The present document covers only the essential technical requirements set out in the first four rows in
Table 1 of ECC Decision (11)02 [i.3] for LPR equipment using a strictly vertical downward orientation of the EUT
antenna.
In addition, the manufacturer needs to consider further installation requirements as specified in Annex E and will have
to provide this information to the user/installer. These installation requirements, however, are not subject to Annex A of
the present document.
Receive-only devices, EUTs exhibiting a receive only mode or a standby mode are not covered by the scope of the
present document.
A further sub-categorization of this LPR device category has been conducted based on:
• the output power, see clause 4.2.2;
• the used Operating Frequency Range (OFR), see clause 4.2.3;
• the used antenna connection, see clause 4.2.4.
The environmental conditions for testing are specified in clause 5.1.
4.2.2 Categorization by output power
The following sub-categorization of LPR EUTs by the output power is used:
• LP1: EUT is a low power LPR (LPLPR) device;
• LP2: EUT is a high power LPR (HPLPR) device.
More information on LP1 and LP2 devices can be found in clause 4.3.7.1.
NOTE: The LP1 category considers a reduced mean and peak power limit by 20 dB compared to ECC
Decision (11)02 [i.3]. This reduction of transmit power is equivalent to the use of a mitigation technique
as described in clause 4.3.7 and therefore no additional mitigation measures are necessary for the LP1
category.
4.2.3 Categorization by Operating Frequency Range (OFR)
The following sub-categorization of LPR EUTs by the operating frequency range is used:
• OFR1: OFR of the EUT is contained in the frequency range 6 GHz to 8,5 GHz;
ETSI
12 ETSI EN 302 729-1 V3.1.1 (2025-05)
• OFR2: OFR of the EUT is contained in the frequency range 24,05 GHz to 26,5 GHz;
• OFR3: OFR of the EUT is contained in the frequency range 57 GHz to 64 GHz;
• OFR4: OFR of the EUT is contained in the frequency range 75 GHz to 85 GHz.
This categorization has been conducted, reflecting the different permitted frequency ranges which can be used for Level
Probing Radars in accordance with European Commission Implementing Decision (EU) 2022/180 [i.7] and ECC
Decision (11)02 [i.3].
4.2.4 Categorization by antenna connection
The following sub-categorization of LPR EUTs by the antenna connection is used:
• ANT1: EUT features an antenna connector, e.g. the EUT is equipped with a dedicated antenna;
• ANT2: EUT has no antenna connector, e.g. the EUT is equipped with an integral antenna.
4.2.5 Summary of LPR sub-categories
An overview of the applicability of transmitter requirements and receiver requirements for the different LPR
sub-categories is shown in Table 1 and Table 2, respectively.

Introduction
ETSI ERM TGUWB decided to develop more specific standards; this means instead of one generic ETSI
EN 302 729 [i.13] for all Level Probing Radar (LPR) devices, a multi-part deliverable was initiated in order to reflect
the intended use in relation to different aspects of the corresponding regulation ECC Decision (11)02 [i.3].
Part 1 of the multi-part deliverable covers the original provisions made in ECC Decision (11)02 [i.3] of 11 March 2011
for LPR equipment with strictly vertical downward installation (see ECC Decision (11)02 [i.3], first four lines of
Table 1 for strictly vertical antenna orientation).
Part 2 of the multi-part deliverable covers the amendments made in ECC Decision (11)02 [i.3] on 5 July 2019 for LPR
equipment with tilted downward installation (see ECC Decision (11)02 [i.3], last three lines of Table 1 for tilted antenna
orientation).
Due to the amendment of ECC Decision (11)02 [i.3] on 5 July 2019, ETSI ERM TGUWB decided to follow henceforth
a two part structure and to only reflect the amendments made in 2019 in part 2 of the series.
More information on the conducted changes in previous versions of the present document can be found in the change
history in Annex H.

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, but as a minimum, shall be that specified in the test
conditions contained in the present document. 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
Technical and regulatory requirements for Level Probing Radars are provided in general in European
Commission Implementing Decision (EU) 2022/180 [i.7] and ECC Decision (11)02 [i.3], which are based on ECC
Report 139 [i.4]. The present document covers only the essential technical requirements set out in the first four rows in
Table 1 of ECC Decision (11)02 [i.3] for LPR equipment using a strictly vertical downward orientation of the EUT
antenna.
In addition, the manufacturer needs to consider further installation requirements as specified in Annex E and will have
to provide this information to the user/installer. These installation requirements, however, are not subject to Annex A of
the present document.
Receive-only devices, EUTs exhibiting a receive only mode or a standby mode are not covered by the scope of the
present document.
A further sub-categorization of this LPR device category has been conducted based on:
• the output power, see clause 4.2.2;
• the used Operating Frequency Range (OFR), see clause 4.2.3;
• the used antenna connection, see clause 4.2.4.
The environmental conditions for testing are specified in clause 5.1.
4.2.2 Categorization by output power
The following sub-categorization of LPR EUTs by the output power is used:
• LP1: EUT is a low power LPR (LPLPR) device;
• LP2: EUT is a high power LPR (HPLPR) device.
More information on LP1 and LP2 devices can be found in clause 4.3.7.1.
NOTE: The LP1 category considers a reduced mean and peak power limit by 20 dB compared to ECC
Decision (11)02 [i.3]. This reduction of transmit power is equivalent to the use of a mitigation technique
as described in clause 4.3.7 and therefore no additional mitigation measures are necessary for the LP1
category.
4.2.3 Categorization by Operating Frequency Range (OFR)
The following sub-categorization of LPR EUTs by the operating frequency range is used:
• OFR1: OFR of the EUT is contained in the frequency range 6 GHz to 8,5 GHz;
