Foreword
This Harmonized European Standard (Telecommunications series) has been produced by ETSI Technical Committee
Electromagnetic compatibility and Radio spectrum Matters (ERM), and is now submitted for the Vote phase of the
ETSI standards Two-step Approval Procedure.
The present document has been produced by ETSI in response to a mandate from the European Commission issued
under Council Directive 98/34/EC (as amended) laying down a procedure for the provision of information in the field of
technical standards and regulations.
The present document is intended to become a Harmonized Standard, the reference of which will be published in the
Official Journal of the European Communities referencing the Directive 1999/5/EC of the European Parliament and of
the Council of 9 March 1999 on radio equipment and telecommunications terminal equipment and the mutual
recognition of their conformity ("the R&TTE Directive ").
NOTE: A list of such Harmonized European Standards is included on the web site http://www.newapproach.org.
Technical specifications relevant to Directive 1999/5/EC are given in annex A.
Proposed national transposition dates
Date of latest announcement of this EN (doa): 3 months after ETSI publication
Date of latest publication of new National Standard
or endorsement of this EN (dop/e): 6 months after doa
Date of withdrawal of any conflicting National Standard (dow): 18 months after doa
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 R&TTE Directive. The modular
structure is shown in EG 201 399 (see bibliography).
UWB Technologies
The present document provides a generic set of technical requirements covering many different types of UWB
technologies used for short range communications. These technologies can be broken down into two groups:
1) Impulse based technologies; and
2) RF carrier based technologies.
The following clauses give a brief overview of these UWB technologies and their associated modulation techniques.
ETSI
7 Final draft ETSI EN 302 065 V1.1.1 (2007-12)
Impulse technology
Impulse derived UWB technology consists of a series of impulses created from a dc voltage step whose risetime can be
modified to provide the maximum useful number of spectral emission frequencies. This derived impulse can then be
suitably modified by the use of filters to locate the resulting waveform within a specific frequency spectrum range. This
filter can be a stand alone filter or incorporated into an antenna design to reduce emissions outside the designated
frequency spectrum.
Modulation techniques include pulse positioning in time, pulse suppression and other techniques to convey information.
The transmitted energy is summed at the receiver to reproduce the transmitted pulse.
This technology is suitable for direct and non-direct line of sight communications, any reflected or time delayed
emissions being suppressed by the receiver input circuits.
RF carrier based technology
RF carrier based UWB technology is based upon classical radio carrier technology suitably modulated by a baseband
modulating process. The modulating process must produce a bandwidth in excess of 50 MHz to be defined as UWB.
Different modulating processes are used to transmit the data information to the receiver and can consist of a series of
single hopping frequencies or multi-tone carriers.
This technology can be used for both direct and non-direct line of sight communications, any reflected or time delayed
emissions being suppressed by the receiver input circuits.
Test and measurement limitations
The ERA report 2006-0713 (see bibliography) has shown that there are practical limitations on measurements of RF
radiated emissions. The minimum radiated levels that can be practically measured in the lower GHz frequency range by
using a radiated measurement setup with a horn antenna and pre-amplifier are typically in the range of about
-70 dBm/MHz to -75 dBm/MHz (e.i.r.p) to have sufficient confidence in the measured result (i.e. UWB signal should
be at least 6 dB above the noise floor of the spectrum analyser and the measurement is performed under far-field
conditions at a one meter distance). However, RF conducted measurements with a pre-amplifier can be carried out to
somewhere around -100 dBm/MHz.
For equipment that have detachable antennas and provide a 50 Ω antenna port, measurements can be made providing
suitable antenna calibrations can be provided.
For integrated antenna equipment, previous ETSI testing standards have allowed equipment modification to provide a
50 Ω adaptor to be added to provide the necessary test port. However, UWB integral equipment and particularly
impulse based technology does not use classical radio techniques and as such is unlikely to have matched 50 Ω antenna
port impedances.
The present document therefore recognizes these difficulties and provides a series of test methods suitable for the
different UWB technologies.

4.1.1.1 Definition
The width of a frequency band such that, below the lower and above the upper frequency limits, the mean powers
emitted are each equal to a percentage of 0,5 % of the total mean power of a given emission.
For the purposes of the present document the measurements are made at the -23 dB points.

4.1.1.3 Limit
The operating bandwidth shall be greater than 50 MHz (at -23 dB relative to the maximum spectral power density).
4.1.1.4 Measurement uncertainty
See table 9.
NOTE: The operating bandwidth is calculated from the two measured frequencies for which the uncertainty
figure for frequency applies. However, the uncertainty of either radiated or conducted power will need to
be taken into account when deriving the uncertainty value for frequency measurements at the -23 dB
points.
4.1.2 Maximum value of mean power spectral density
4.1.2.1 Definition
The maximum mean power spectral density (specified as e.i.r.p.) of the device under test, at a particular frequency, is
the average power per unit bandwidth (centred on that frequency) radiated in the direction of the maximum level under
the specified conditions of measurement.
4.1.2.2 Test procedure
This test shall be performed using a radiated or conducted test procedure (see clause 5.8.2) for the frequencies as shown
in table 2.
ETSI

Table 2: Maximum value of mean power spectral density limit
Frequency Maximum value of mean power
(GHz) spectral density (dBm/MHz)
3,4 < f ≤ 4,8 ≤ -41,3 (see note 1)
4,2 < f ≤ 4,8 ≤ -41,3 (see note 2)
6 < f ≤ 8,5 ≤ -41,3 (see note 2)
NOTE 1: LDC is required (see clause 4.1.7). If LDC is not
implemented then the following applies:
- 3,4 GHz to 3,8 GHz ≤ -80 dBm/MHz;
- 3,8 GHz to 4,2 GHz ≤ -70 dBm/MHz.
NOTE 2: In case of devices installed in road and rail vehicles,
operation is subject to the implementation of Transmit
Power Control (TPC) with a range of 12 dB with respect to
the maximum value of mean power spectral density. If
TPC is not implemented then the following applies:
- 4,2 GHz to 4,8 GHz ≤ -53,3 dBm/MHz;

radiated power occurs, radiated in the direction of the maximum level under the specified conditions of measurement.
4.1.3.2 Test procedure
This test shall be performed using a radiated or conducted test procedure (see clause 5.8.3).
4.1.3.3 Limit
The maximum peak power limit measured using the above test procedure shall not exceed the limits given in table 4.

3,4 < f ≤ 4,8 0 (see note 1)
4,2 < f ≤ 4,8 0 (see note 2)
6 < f ≤ 8,5 0 (see note 2)
NOTE 1: LDC is required (see 4.1.7). If LDC is not implemented then the
following applies:
- 3,4 GHz to 3,8 GHz ≤ -40 dBm, measured in 50 MHz;
- 3,8 GHz to 4,2 GHz ≤ -30 dBm, measured in 50 MHz.
NOTE 2: In case of devices installed in road and rail vehicles, operation is
subject to the implementation of Transmit Power Control (TPC)
with a range of 12 dB with respect to the maximum value of peak
power. If TPC is not implemented then the following applies:
- 4,2 GHz to 4,8 GHz ≤ -12 dBm, measured in 50 MHz;
- 6 GHz to 8,5 GHz ≤ -12 dBm, measured in 50 MHz.
The power reading on the spectrum analyser can be directly related to the peak power limit when a spectrum analyser
resolution bandwidth of 50 MHz is used for the measurements. If a spectrum analyser resolution bandwidth of X MHz
is used instead, the maximum peak power limit shall be scaled down by a factor of 20 log (50/X), where X represents
the measurement bandwidth used.
EXAMPLE: If the maximum peak power in a particular frequency band is 0 dBm/50 MHz, and a 3 MHz
resolution bandwidth is used in case of an impulsive technology, then the measured value shall not
exceed -24,4 dBm (see annex D).
For rf carrier based modulation using multi-tone carriers and not having gating techniques implemented, the maximum
peak power limit shall be scaled down by a different factor of 10 log(50/X), where X represents the measurement
bandwidth used.
4.1.3.4 Maximum allowable measurement uncertainty
See table 9.
4.1.4 Transmit Power Control
4.1.4.1 Definition
Transmit Power Control (TPC) is a mechanism to be used to ensure an interference mitigation on the aggregate power
from a large number of devices. The TPC mechanism shall provide the full range from the highest to the lowest power
level of the device and is required for UWB devices intended to be used in road or rail vehicles.
4.1.4.2 Test procedure
TPC tests to assess the highest and lowest power spectral density level shall be measured using a radiated or conducted
test procedure (see clauses 5.8.2).
4.1.4.3 Limit
The maximum value of power spectral density when configured to operate at the highest level of the TPC range shall
not exceed the levels given in table 5a.

Foreword
This Harmonized European Standard (Telecommunications series) has been produced by ETSI Technical Committee
Electromagnetic compatibility and Radio spectrum Matters (ERM).
The present document has been produced by ETSI in response to a mandate from the European Commission issued
under Council Directive 98/34/EC (as amended) laying down a procedure for the provision of information in the field of
technical standards and regulations.
The present document is intended to become a Harmonized Standard, the reference of which will be published in the
Official Journal of the European Communities referencing the Directive 1999/5/EC of the European Parliament and of
the Council of 9 March 1999 on radio equipment and telecommunications terminal equipment and the mutual
recognition of their conformity ("the R&TTE Directive ").
NOTE: A list of such Harmonized European Standards is included on the web site http://www.newapproach.org.
Technical specifications relevant to Directive 1999/5/EC are given in annex A.

Date of adoption of this EN: 15 February 2008
Date of latest announcement of this EN (doa): 31 May 2008
Date of latest publication of new National Standard
or endorsement of this EN (dop/e): 30 November 2008
Date of withdrawal of any conflicting National Standard (dow): 30 November 2009
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 R&TTE Directive. The modular
structure is shown in EG 201 399 (see bibliography).
UWB Technologies
The present document provides a generic set of technical requirements covering many different types of UWB
technologies used for short range communications. These technologies can be broken down into two groups:
1) Impulse based technologies; and
2) RF carrier based technologies.
ETSI
7 ETSI EN 302 065 V1.1.1 (2008-02)
The following clauses give a brief overview of these UWB technologies and their associated modulation techniques.
Impulse technology
Impulse derived UWB technology consists of a series of impulses created from a dc voltage step whose risetime can be
modified to provide the maximum useful number of spectral emission frequencies. This derived impulse can then be
suitably modified by the use of filters to locate the resulting waveform within a specific frequency spectrum range. This
filter can be a stand alone filter or incorporated into an antenna design to reduce emissions outside the designated
frequency spectrum.
Modulation techniques include pulse positioning in time, pulse suppression and other techniques to convey information.
The transmitted energy is summed at the receiver to reproduce the transmitted pulse.
This technology is suitable for direct and non-direct line of sight communications, any reflected or time delayed
emissions being suppressed by the receiver input circuits.
RF carrier based technology
RF carrier based UWB technology is based upon classical radio carrier technology suitably modulated by a baseband
modulating process. The modulating process must produce a bandwidth in excess of 50 MHz to be defined as UWB.
Different modulating processes are used to transmit the data information to the receiver and can consist of a series of
single hopping frequencies or multi-tone carriers.
This technology can be used for both direct and non-direct line of sight communications, any reflected or time delayed
emissions being suppressed by the receiver input circuits.
Test and measurement limitations
The ERA report 2006-0713 (see bibliography) has shown that there are practical limitations on measurements of RF
radiated emissions. The minimum radiated levels that can be practically measured in the lower GHz frequency range by
using a radiated measurement setup with a horn antenna and pre-amplifier are typically in the range of about
-70 dBm/MHz to -75 dBm/MHz (e.i.r.p) to have sufficient confidence in the measured result (i.e. UWB signal should
be at least 6 dB above the noise floor of the spectrum analyser and the measurement is performed under far-field
conditions at a one meter distance). However, RF conducted measurements with a pre-amplifier can be carried out to
somewhere around -100 dBm/MHz.
For equipment that have detachable antennas and provide a 50 Ω antenna port, measurements can be made providing
suitable antenna calibrations can be provided.
For integrated antenna equipment, previous ETSI testing standards have allowed equipment modification to provide a
50 Ω adaptor to be added to provide the necessary test port. However, UWB integral equipment and particularly
impulse based technology does not use classical radio techniques and as such is unlikely to have matched 50 Ω antenna
port impedances.
The present document therefore recognizes these difficulties and provides a series of test methods suitable for the
different UWB technologies.

See table 9.
NOTE: The operating bandwidth is calculated from the two measured frequencies for which the uncertainty
figure for frequency applies. However, the uncertainty of either radiated or conducted power will need to
be taken into account when deriving the uncertainty value for frequency measurements at the -23 dB
points.
4.1.2 Maximum value of mean power spectral density
4.1.2.1 Definition
The maximum mean power spectral density (specified as e.i.r.p.) of the device under test, at a particular frequency, is

resolution bandwidth of 50 MHz is used for the measurements. If a spectrum analyser resolution bandwidth of X MHz
is used instead, the maximum peak power limit shall be scaled down by a factor of 20 log (50/X), where X represents
the measurement bandwidth used.

resolution bandwidth is used in case of an impulsive technology, then the measured value shall not
exceed -24,4 dBm (see annex D).

technical standards and regulations.
The present document is intended to become a Harmonized Standard, the reference of which will be published in the
Official Journal of the European Communities referencing the Directive 1999/5/EC of the European Parliament and of
the Council of 9 March 1999 on radio equipment and telecommunications terminal equipment and the mutual
recognition of their conformity ("the R&TTE Directive ").

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 R&TTE Directive. The modular
structure is shown in EG 201 399 (see bibliography).
UWB Technologies
The present document provides a generic set of technical requirements covering many different types of UWB
technologies used for short range communications. These technologies can be broken down into two groups:
1) Impulse based technologies; and
2) RF carrier based technologies.
ETSI
7 ETSI EN 302 065 V1.1.1 (2008-02)
The following clauses give a brief overview of these UWB technologies and their associated modulation techniques.
Impulse technology
Impulse derived UWB technology consists of a series of impulses created from a dc voltage step whose risetime can be
modified to provide the maximum useful number of spectral emission frequencies. This derived impulse can then be
suitably modified by the use of filters to locate the resulting waveform within a specific frequency spectrum range. This
filter can be a stand alone filter or incorporated into an antenna design to reduce emissions outside the designated
frequency spectrum.
Modulation techniques include pulse positioning in time, pulse suppression and other techniques to convey information.
The transmitted energy is summed at the receiver to reproduce the transmitted pulse.
This technology is suitable for direct and non-direct line of sight communications, any reflected or time delayed
emissions being suppressed by the receiver input circuits.
RF carrier based technology
RF carrier based UWB technology is based upon classical radio carrier technology suitably modulated by a baseband
modulating process. The modulating process must produce a bandwidth in excess of 50 MHz to be defined as UWB.
Different modulating processes are used to transmit the data information to the receiver and can consist of a series of
single hopping frequencies or multi-tone carriers.
This technology can be used for both direct and non-direct line of sight communications, any reflected or time delayed
emissions being suppressed by the receiver input circuits.
Test and measurement limitations
The ERA report 2006-0713 (see bibliography) has shown that there are practical limitations on measurements of RF
radiated emissions. The minimum radiated levels that can be practically measured in the lower GHz frequency range by
using a radiated measurement setup with a horn antenna and pre-amplifier are typically in the range of about
-70 dBm/MHz to -75 dBm/MHz (e.i.r.p) to have sufficient confidence in the measured result (i.e. UWB signal should
be at least 6 dB above the noise floor of the spectrum analyser and the measurement is performed under far-field
conditions at a one meter distance). However, RF conducted measurements with a pre-amplifier can be carried out to
somewhere around -100 dBm/MHz.
For equipment that have detachable antennas and provide a 50 Ω antenna port, measurements can be made providing
suitable antenna calibrations can be provided.
For integrated antenna equipment, previous ETSI testing standards have allowed equipment modification to provide a
50 Ω adaptor to be added to provide the necessary test port. However, UWB integral equipment and particularly
impulse based technology does not use classical radio techniques and as such is unlikely to have matched 50 Ω antenna
port impedances.
The present document therefore recognizes these difficulties and provides a series of test methods suitable for the
different UWB technologies.

4.1 Technical requirements
4.1.1 Operating bandwidth
4.1.1.1 Definition
The width of a frequency band such that, below the lower and above the upper frequency limits, the mean powers
emitted are each equal to a percentage of 0,5 % of the total mean power of a given emission.
For the purposes of the present document the measurements are made at the -23 dB points.
4.1.1.2 Test procedure
This test shall be performed using a radiated or conducted test procedure (see clause 5.8.4).
4.1.1.3 Limit

ETSI
12 ETSI EN 302 065 V1.1.1 (2008-02)
4.1.1.4 Measurement uncertainty
See table 9.
NOTE: The operating bandwidth is calculated from the two measured frequencies for which the uncertainty
figure for frequency applies. However, the uncertainty of either radiated or conducted power will need to
be taken into account when deriving the uncertainty value for frequency measurements at the -23 dB
points.
4.1.2 Maximum value of mean power spectral density
4.1.2.1 Definition
The maximum mean power spectral density (specified as e.i.r.p.) of the device under test, at a particular frequency, is
the average power per unit bandwidth (centred on that frequency) radiated in the direction of the maximum level under

Frequency Maximum value of mean power
(GHz) spectral density (dBm/MHz)
3,4 < f ≤ 4,8 ≤ -41,3 (see note 1)
4,2 < f ≤ 4,8 ≤ -41,3 (see note 2)
6 < f ≤ 8,5 ≤ -41,3 (see note 2)

- 3,8 GHz to 4,2 GHz ≤ -70 dBm/MHz.
NOTE 2: In case of devices installed in road and rail vehicles,
operation is subject to the implementation of Transmit
Power Control (TPC) with a range of 12 dB with respect to
the maximum value of mean power spectral density. If

4.1.3 Maximum value of peak power
4.1.3.1 Definition
The power specified as e.i.r.p. contained within a 50 MHz bandwidth at the frequency at which the highest mean
radiated power occurs, radiated in the direction of the maximum level under the specified conditions of measurement.
4.1.3.2 Test procedure
This test shall be performed using a radiated or conducted test procedure (see clause 5.8.3).
4.1.3.3 Limit
The maximum peak power limit measured using the above test procedure shall not exceed the limits given in table 4.
Table 4: Maximum peak power limit
Frequency Maximum peak power
(GHz) (dBm, measured in 50 MHz)
3,4 < f ≤ 4,8 0 (see note 1)
4,2 < f ≤ 4,8 0 (see note 2)
6 < f ≤ 8,5 0 (see note 2)
NOTE 1: LDC is required (see 4.1.7). If LDC is not implemented then the
following applies:
- 3,4 GHz to 3,8 GHz ≤ -40 dBm, measured in 50 MHz;
- 3,8 GHz to 4,2 GHz ≤ -30 dBm, measured in 50 MHz.
NOTE 2: In case of devices installed in road and rail vehicles, operation is
subject to the implementation of Transmit Power Control (TPC)
with a range of 12 dB with respect to the maximum value of peak
power. If TPC is not implemented then the following applies:
- 4,2 GHz to 4,8 GHz ≤ -12 dBm, measured in 50 MHz;
- 6 GHz to 8,5 GHz ≤ -12 dBm, measured in 50 MHz.
The power reading on the spectrum analyser can be directly related to the peak power limit when a spectrum analyser
resolution bandwidth of 50 MHz is used for the measurements. If a spectrum analyser resolution bandwidth of X MHz
is used instead, the maximum peak power limit shall be scaled down by a factor of 20 log (50/X), where X represents
the measurement bandwidth used.
EXAMPLE: If the maximum peak power in a particular frequency band is 0 dBm/50 MHz, and a 3 MHz
resolution bandwidth is used in case of an impulsive technology, then the measured value shall not
exceed -24,4 dBm (see annex D).
ETSI
14 ETSI EN 302 065 V1.1.1 (2008-02)
For rf carrier based modulation using multi-tone carriers and not having gating techniques implemented, the maximum
peak power limit shall be scaled down by a different factor of 10 log(50/X), where X represents the measurement
bandwidth used.
