Introduction
For the case of the present document, the applicable harmonised standard has been ETSI EN 302 065-3 [i.12], for UWB
devices for ground based vehicular applications, which was published in the OJEU without restriction at
10 March 2017 [i.9] and then published at 5 February 2020 [i.10] with the following restriction:
• "This harmonised standard does not set out technical specifications for 'trigger before-transmit techniques'.
Implementing Decision (EU) 2019/785, however, imposes, as of 16 November 2019, technical requirements to
be used within the bands 3,8-4.2 GHz and 6-8,5 GHz for vehicular access systems using trigger-before
transmit. Therefore compliance with this harmonised standard does not ensure compliance with Decision (EU)
2019/785 and accordingly does not confer a presumption of conformity with those essential requirements set
out in Article 3 (2) of Directive 2014/53/EU which relate to 'trigger-before-transmit techniques'".
In order to consider the above points, ETSI ERM TGUWB decided to develop more specific standards; for the present
document this means instead of a generic ETSI EN 302 065-3 [i.12] standard for all road and rail vehicles applications,
an ETSI EN 302 065-3-1 for UWB devices for vehicular access systems. Other sub-parts for UWB devices installed in
motor and railway vehicles may follow (ETSI EN 302 065-3-x).
More details on the changes of the present document to previous versions are provided in annex F.

ETSI

1 Scope
The present document specifies technical requirements, limits and test methods for equipment employing UWB for
vehicular access devices installed in motor and railway vehicles in the frequency ranges 3,8 GHz to 4,2 GHz and
6,0 GHz to 8,5 GHz.
These equipment types are intended to be utilized for vehicle access, vehicle immobilization and extended vehicle
access control functionalities (like closing windows or remotely starting the car).
Further details of the covered EUT can be found in clause 4.2 in the present document.

Introduction
For the present document, the applicable harmonised standard has been ETSI EN 302 065-3 [i.12], for UWB devices for
ground based vehicular applications, which was published in the OJEU without restriction at 10 March 2017 [i.9] and
then published at 5 February 2020 [i.10] with the following restriction:
• "This harmonised standard does not set out technical specifications for 'trigger before-transmit techniques'.
Implementing Decision (EU) 2019/785, however, imposes, as of 16 November 2019, technical requirements to
be used within the bands 3,8-4.2 GHz and 6-8,5 GHz for vehicular access systems using trigger-before
transmit. Therefore, compliance with this harmonised standard does not ensure compliance with Decision
(EU) 2019/785 and accordingly does not confer a presumption of conformity with those essential requirements
set out in Article 3 (2) of Directive 2014/53/EU which relate to 'trigger-before-transmit techniques'".
In order to consider the above points, ETSI ERM TGUWB decided to develop more specific standards; for the present
document this means instead of a generic ETSI EN 302 065-3 [i.12] standard for all road and rail vehicles applications,
an ETSI EN 302 065-3-1 for UWB devices for vehicular access systems. Other sub-parts for UWB devices installed in
motor and railway vehicles may follow (ETSI EN 302 065-3-x).
More details on the changes of the present document to previous versions are provided in annex F.

ETSI
9 Final draft ETSI EN 302 065-3-1 V3.2.0 (2024-12)
1 Scope
The present document specifies technical requirements, limits and test methods for equipment employing UWB for
vehicular access devices installed in motor and railway vehicles in the frequency ranges 3,8 GHz to 4,2 GHz and
6,0 GHz to 8,5 GHz.
These equipment types are intended to be utilized for vehicle access, vehicle immobilization and extended vehicle
access control functionalities (like closing windows or remotely starting the car).
Further details of the covered EUT can be found in clause 4.2.

NOTE: Time-of-Flight between EUT and companion device.
packet: used to refer to an UWB data frame or aggregated pulse sequence, that is sent over the air
NOTE: Typically, one packet represents a continuous T time.
on
receiver spurious emissions: receiver unwanted emissions that emanate from the EUT
NOTE: Receiver spurious emissions are generated internally by the receiver or result from the interaction of the
RX coupling with the TX signal.
responder: EUT role in an UWB transmission sequence in which the EUT responds to an UWB transmission
NOTE: Typically an UWB transmission is a received UWB packet (for more details see clause 4.3.7.2.).
system trigger event: trigger event on system level
NOTE: Usually out of scope for EUT.
Time-of-Flight (ToF): travel time of the radio signal between transmitter and receiver
Trigger-Before-Transmit (TBT): mitigation technique as required for vehicular access systems
NOTE: See ECC/DEC/(06)04 [i.4].
vehicle transceiver: UWB enabled unit, installed in the vehicle

Introduction
For the present document, the applicable harmonised standard has been ETSI EN 302 065-3 [i.12], for UWB devices for
ground based vehicular applications, which was published in the OJEU without restriction at 10 March 2017 [i.9] and
then published at 5 February 2020 [i.10] with the following restriction:
• "This harmonised standard does not set out technical specifications for 'trigger before-transmit techniques'.
Implementing Decision (EU) 2019/785, however, imposes, as of 16 November 2019, technical requirements to
be used within the bands 3,8-4.2 GHz and 6-8,5 GHz for vehicular access systems using trigger-before
transmit. Therefore, compliance with this harmonised standard does not ensure compliance with Decision
(EU) 2019/785 and accordingly does not confer a presumption of conformity with those essential requirements
set out in Article 3 (2) of Directive 2014/53/EU which relate to 'trigger-before-transmit techniques'".
In order to consider the above points, ETSI ERM TGUWB decided to develop more specific standards; for the present
document this means instead of a generic ETSI EN 302 065-3 [i.12] standard for all road and rail vehicles applications,
an ETSI EN 302 065-3-1 for UWB devices for vehicular access systems. Other sub-parts for UWB devices installed in
motor and railway vehicles may follow (ETSI EN 302 065-3-x).
More details on the changes of the present document to previous versions are provided in annex F.

1 Scope
The present document specifies technical requirements, limits and test methods for equipment employing UWB for
vehicular access devices installed in motor and railway vehicles in the frequency ranges 3,8 GHz to 4,2 GHz and
6,0 GHz to 8,5 GHz.
These equipment types are intended to be utilized for vehicle access, vehicle immobilization and extended vehicle
access control functionalities (like closing windows or remotely starting the car).
Further details of the covered EUT can be found in clause 4.2.

3.1 Terms
For the purposes of the present document, the terms given in ETSI EN 303 883-1 [1], ETSI EN 303 883-2 [2] and the
following apply:
control equipment: equipment capable of sending control messages to the EUT, as well as receiving responses to that
control command or other status messages, in order to setup the EUT and perform a measurement procedure
control message: one or more commands used to control or configure the EUT
NOTE: Typically submitted on a specific, non-UWB control interface, like CAN-bus interface.
EUT trigger event: trigger event on EUT level
NOTE: Which is used for measurement procedures in the present document.
initiator: EUT role in an UWB transmission sequence in which the EUT initiates UWB transmission upon a system
trigger event
NOTE: For more details see clause 4.3.7.2.
message: sequence or exchange of two or more packets in order to transfer information, in particular to generate a
ranging information
NOTE: Time-of-Flight between EUT and companion device.
packet: used to refer to an UWB data frame or aggregated pulse sequence, that is sent over the air
NOTE: Typically, one packet represents a continuous T time.
on
receiver spurious emissions: receiver unwanted emissions that emanate from the EUT
NOTE: Receiver spurious emissions are generated internally by the receiver or result from the interaction of the
RX coupling with the TX signal.
responder: EUT role in an UWB transmission sequence in which the EUT responds to an UWB transmission
NOTE: Typically an UWB transmission is a received UWB packet (for more details see clause 4.3.7.2.).
system trigger event: trigger event on system level
NOTE: Usually out of scope for EUT.
Time-of-Flight (ToF): travel time of the radio signal between transmitter and receiver
Trigger-Before-Transmit (TBT): mitigation technique as required for vehicular access systems
NOTE: See ECC/DEC/(06)04 [i.4].
vehicle transceiver: UWB enabled unit, installed in the vehicle

Introduction
For the present document, the applicable harmonised standard has been ETSI EN 302 065-3 [i.12], for UWB devices for
ground based vehicular applications, which was published in the OJEU without restriction at 10 March 2017 [i.9] and
then published at 5 February 2020 [i.10] with the following restriction:
• "This harmonised standard does not set out technical specifications for 'trigger before-transmit techniques'.
Implementing Decision (EU) 2019/785, however, imposes, as of 16 November 2019, technical requirements to
be used within the bands 3,8-4.2 GHz and 6-8,5 GHz for vehicular access systems using trigger-before
transmit. Therefore, compliance with this harmonised standard does not ensure compliance with Decision
(EU) 2019/785 and accordingly does not confer a presumption of conformity with those essential requirements
set out in Article 3 (2) of Directive 2014/53/EU which relate to 'trigger-before-transmit techniques'".
In order to consider the above points, ETSI ERM TGUWB decided to develop more specific standards; for the present
document this means instead of a generic ETSI EN 302 065-3 [i.12] standard for all road and rail vehicles applications,
an ETSI EN 302 065-3-1 for UWB devices for vehicular access systems. Other sub-parts for UWB devices installed in
motor and railway vehicles may follow (ETSI EN 302 065-3-x).
More details on the changes of the present document to previous versions are provided in annex F.

1 Scope
The present document specifies technical requirements, limits and test methods for equipment employing UWB for
vehicular access devices installed in motor and railway vehicles in the frequency ranges 3,8 GHz to 4,2 GHz and
6,0 GHz to 8,5 GHz.
These equipment types are intended to be utilized for vehicle access, vehicle immobilization and extended vehicle
access control functionalities (like closing windows or remotely starting the car).
Further details of the covered EUT can be found in clause 4.2.

3 Definition of terms, symbols and abbreviations
3.1 Terms
For the purposes of the present document, the terms given in ETSI EN 303 883-1 [1], ETSI EN 303 883-2 [2] and the
following apply:
control equipment: equipment capable of sending control messages to the EUT, as well as receiving responses to that
control command or other status messages, in order to setup the EUT and perform a measurement procedure
control message: one or more commands used to control or configure the EUT
NOTE: Typically submitted on a specific, non-UWB control interface, like CAN-bus interface.
EUT trigger event: trigger event on EUT level
NOTE: Which is used for measurement procedures in the present document.
initiator: EUT role in an UWB transmission sequence in which the EUT initiates UWB transmission upon a system
trigger event
NOTE: For more details see clause 4.3.7.2.
message: sequence or exchange of two or more packets in order to transfer information, in particular to generate a
ranging information
NOTE: Time-of-Flight between EUT and companion device.
packet: used to refer to an UWB data frame or aggregated pulse sequence, that is sent over the air
NOTE: Typically, one packet represents a continuous T time.
on
receiver spurious emissions: receiver unwanted emissions that emanate from the EUT
NOTE: Receiver spurious emissions are generated internally by the receiver or result from the interaction of the
RX coupling with the TX signal.
responder: EUT role in an UWB transmission sequence in which the EUT responds to an UWB transmission
NOTE: Typically an UWB transmission is a received UWB packet (for more details see clause 4.3.7.2.).
system trigger event: trigger event on system level
NOTE: Usually out of scope for EUT.
Time-of-Flight (ToF): travel time of the radio signal between transmitter and receiver
Trigger-Before-Transmit (TBT): mitigation technique as required for vehicular access systems
NOTE: See ECC/DEC/(06)04 [i.4].
vehicle transceiver: UWB enabled unit, installed in the vehicle
