Brezžični prenos električne energije s tehnologijami, ki ne uporabljajo radiofrekvenčnega snopa v območjih 19–21 kHz, 59–61 kHz, 79–90 kHz,100–300 kHz, 6765–6795 kHz - Harmonizirani standard, ki zajema bistvene zahteve člena 3.2 direktive 2014/53/EU
V tem dokumentu so navedene tehnične lastnosti in metode merjenja za sisteme brezžičnega prenosa električne energije (WPT) na podlagi tehnologij, ki ne vključujejo radiofrekvenčnega snopa v območjih 19–21 kHz, 59–61 kHz, 79–90 kHz,100–300 kHz, 6765–6795 kHz.
Ta dokument zajema sisteme brezžičnega prenosa električne energije, ki se obravnavajo kot radijska oprema, ker vključujejo lastno radijsko komunikacijsko ali radiofrekvenčno določanje prek vmesnika ali vrat WPT v določenih frekvenčnih območjih WPT.
Tovrstni sistemi običajno vključujejo:
1) oddajnik električne energije z dodatno možnostjo komunikacije za nadzor funkcije napajanja v povezavi s sprejemnim delom. Ta oddajnik se lahko imenuje tudi bazna postaja.
2) sprejemnik električne energije, ki s prejeto energijo oskrbuje mobilno napravo in izvaja funkcijo upravljanja/nadzora za stanje ter napajanje mobilne naprave.
Oba dela lahko poleg prenašanja električne energije skupaj prenašata in sprejemata tudi podatke, kot so na primer podatki za nadzor stanja mobilne naprave ter optimizacijo načina prenosa električne energije.
Tovrstna radijska oprema lahko deluje v dovoljenih frekvenčnih pasovih pod 30 MHz, kot je določeno v preglednici 1.
Ta dokument zajema fiksne, mobilne in prenosne sisteme.

1 Scope
The present document specifies technical characteristics and methods of measurements for wireless power transmission
(WPT) systems using technologies other than radio frequency beam in the 19 - 21 kHz, 59 - 61 kHz, 79 - 90 kHz,
100 - 300 kHz, 6 765 - 6 795 kHz ranges.
For the purpose of the present document WPT systems are classified into three different cases according to Table 1.
Table 1: Distinction between WPT systems cases with regard to the communication technology
WPT Cases RE-D article 3.2 RE-D article 3.1b EMC-D
(see note 3)
1: only energy N/A N/A CENELEC EN 55011 [i.7]
transmission, no data Group 2 (or more specific
communication CENELEC standard if
applicable), see note 1
2: energy transmission ETSI EN 303 417 (the ETSI EN 301 489-1 [i.8] N/A
and data communication present document) ETSI EN 301 489-3 [i.9]
in frequency ranges
covered by the present
document
3: energy transmission in Based on the communication function, this case is a "combined equipment" according to RE-
frequency ranges D (see ETSI EG 203 367 [i.5]). Therefore, two options for homologation could be used:
covered by the present
• Option 1: energy transmission frequencies (the present document), data
document and data
communication frequencies: related ETSI standard
communication in
• Option 2: energy transmission frequencies CENELEC EN 55011 [i.7] (see note 1
different frequency
and note 2), data communication frequencies: related ETSI standard
ranges
NOTE 1: WPT systems are expected to be included in future revision of CENELEC EN 55011 [i.7].
NOTE 2: CENELEC EN 55011 [i.7] are to be listed under the related articles in the OJEU for RE-D.
NOTE 3: The division into these three cases could change once ITU has finalized their work on WPT-systems in
response to Question ITU-R 210-3/1 and WRC 19 Agenda Item 9.1, Issue 9.1.6 [i.11].
The present document covers wireless power transfer systems according to cases 2 and 3 of Table 1, i.e. systems which
consist of:
1) A power transmitter, with additional communication capability to control the charge function in conjunction
with the receiving part. The power transmitter could also be named as charger.
2) A receiver, which supplies the received energy to a battery and performs a control/supervision function for the
battery status and charge operation.
Both parts in combination are able to transmit and receive data in addition to the power transfer mode e.g. to control the
battery status and to optimize the transfer mode.
These radio equipment types are capable of operating in the permitted frequency bands below 30 MHz as specified in
Table 2.
The present document covers fixed systems, mobile and portable systems.
The limits and the frequency ranges of the present document are based on 2013/752/EU [i.2] and ERC/REC 70-03 [i.1].
For the clarification of open questions for high power wireless power transmission systems to charge vehicles a SRdoc
ETSI TR 103 409 [i.4] was prepared. New specific requirements for such systems (e.g. higher H-field emission limits in
the 79 - 90 kHz band) will be reflected within a future revision of the present document.

4 Technical requirements
4.1 Environmental conditions
The technical requirements of the present document apply under the environmental profile for operation of the
equipment, which shall be declared by the manufacturer. The equipment shall comply with all the technical
requirements of the present document which are identified as applicable in annex A at all times when operating within
the boundary limits of the declared operational environmental profile. The test conditions are defined in clause 5.3.
4.2 General
4.2.1 Background information
In this clause all general considerations for the testing of wireless power transmission (WPT) systems using
technologies other than radio frequency beam in the 19 - 21 kHz, 59 - 61 kHz, 79 - 90 kHz, 100 - 300 kHz,
6 765 - 6 795 kHz ranges are given. The tests cover all different operational modes, as described in clause 4.2.3.
All permitted ranges of operation of the equipment (see clause 4.3.2) shall be declared by the equipment manufacturer.
ETSI
11 Draft ETSI EN 303 417 V1.1.0 (2016-12)
The modulation and energy transfer of the WPT system during testing should be representative of normal use of the
equipment. The manufacturer shall employ each implemented mode of operation of the equipment (see clause 4.2.3)
which results in power transmission out of the WPT system which would be available in operation, and should ensure
that the requirements in clause 4.3 and clause 4.4 are fulfilled.
4.2.2 Wanted performance criteria
A WPT system always consists of a charger and a battery which are in proximity to each other. The performance of a
WPT system is dependent on the related operational mode, see clause 4.2.3.
Based on the different specific operational modes, additional dedicated RX requirements (e.g. blocking, ACS) cannot be
specified for WPT systems, see clause 4.4.
Therefore, the manufacturer shall declare and publish the performance criteria used to determine the performance of the
receiving parts inside the WPT system (related to the mode).
4.2.3 WPT operational modes
Because of the close interaction between charger and battery the manufacturer shall provide all necessary parts for the
presentation of equipment and for testing purposes. The description of the setup including the positioning and
mechanical orientation of both parts shall be provided since this affects the radiated emissions. For using different
batteries or power receiving parts with one charger, the manufacturer shall declare the typical and the worst case
combinations with regard to radiated emissions and provide such combinations for testing.
In certain cases it may be not possible to provide the necessary samples of batteries due to unavailability. In these cases
the manufacturer has to declare that the charger was developed based on certain batteries and such charger/battery
combinations shall be provided for testing.
The manufacturer shall declare for each possible operation mode of the WPT system (overview see Table 3):
a) charging mode/power transfer/system in resonance;
b) communication mode (data transmission from and to the battery);
c) determination of the charging action e.g. to find the resonance frequency of the system or optimal charging
parameters of the WPT systems.
Additional declarations to establish the appropriate test conditions:
a) the mechanical setup/alignment;
b) the maximum allowed values for the x-y-z offset within the alignment (worst-case alignment)
c) the mechanical orientation;
d) the permitted range of frequencies;
e) the range of operating conditions including the duty cycle or pulsing operational parameter;
f) power requirements;
g) information about which part of the WPT System can be interpreted as transmitter (mode dependent).
The measurements itself shall be done on these actual set-up and operating conditions for each mode.
NOTE: If during the initial establishment of the charging mode (mode 2 from Table 3), no or very low emission
are occurring, this initialization mode can be declared as irrelevant for the test.

4.2.4.1 General
Each WPT system submitted for testing shall fulfil the requirements of the present document on all frequencies over
which it is intended to operate.
The manufacturer shall declare the permitted frequency ranges (see clause 4.4.2), the range of operating conditions and
power requirements as applicable, to establish the appropriate test conditions.
Additionally, technical documentation and operating manuals, sufficient to make the test, shall be supplied.
If a WPT system is designed to operate with different system mode (see clause 4.2.3), measurement of each mode shall
be performed, according to the present document, on samples of equipment defined in clause 4.2.4.2.
To simplify and harmonize the testing procedures between different testing laboratories, measurements shall be
performed, according to the present document, on samples defined in clauses 4.2.4.2 to 4.2.4.4.
4.2.4.2 Choice of model for testing
The manufacturer shall provide one or more samples of the WPT system, as appropriate for testing.
Standalone WPT systems shall be offered by the manufacturer complete with any ancillary equipment needed for
testing.
If a WPT system has several optional features, considered not to affect the emission parameters then the tests need only
to be performed on the WPT system configured with that combination of features considered to be the most complex, as
proposed by the manufacturer and agreed by the test laboratory.
The performance of the WPT system submitted for testing shall be representative of the performance of the
corresponding production model.
4.2.4.3 Testing of WPT systems
If a family of WPT systems has alternative radiated field strengths provided by the use of separate power modules or
add on stages, then these shall be declared by the manufacturer. Each module or add on stage shall be tested in
combination with the equipment. As a minimum, measurements of the radiated H-field strength and spurious emissions
shall be performed for each combination and shall be stated in the test report.
The manufacturer has to submit the necessary parts as charger and battery for the test. The test shall be done in the
worst case setup/mechanical arrangement.
4.2.4.4 On-site testing
In certain cases it may not be possible to provide representative samples of antennas and/or equipment due to physical
constraints. In these cases equivalent measurements to the present document shall be made at a representative
installation of the equipment (on-site).
4.2.5 Mechanical and electrical design

4.2.5.3 Shut-off facility
If the WPT system is equipped with an automatic shut-off facility (for communication and/or power transfer), it should
be made inoperative for the duration of the test.
If this would be not possible, e.g. to avoid the damage of the battery, the test shall be performed during normal
operation.
4.3 Transmitter conformance requirements
4.3.1 General
A WPT system could work in different mode (see clause 4.2.3, Table 3) and this could influence the radiated emission.
Depending on the operation mode of the WPT system the manufacturer has to declare the operational modes (e.g.
combination charger/battery or stand-alone charger), see clause 4.2.3, Table 3. The emission test shall be performed for
all operational modes (see Table 3).

1 Scope
The present document specifies technical characteristics and methods of measurements for wireless power transmission
(WPT) systems, using technologies other than radio frequency beam, in the 19 - 21 kHz, 59 - 61 kHz, 79 - 90 kHz,
100 - 300 kHz, 6 765 - 6 795 kHz ranges.
The present document covers wireless power transmission systems which are regarded as radio equipment since
including inherent radio communication functionality or radiodetermination via the WPT interface or port at the specific
WPT frequency ranges.
Such systems usually consist of:
1) A power transmitter, with additional communication capability to control the charge function, in conjunction
with the receiving part. The power transmitter could also be named as base station.
2) A power receiver, which supplies the received energy to a mobile device and performs a control/supervision
function for the mobile device status and charge operation. Both parts in combination are able to transmit and
receive data in addition to the power transmission mode e.g. to control the mobile device status and to
optimize the power transmission mode.
These radio equipment types are capable of operating in the permitted frequency bands below 30 MHz as specified in
Table 1.
The present document covers fixed systems, mobile and portable systems.
Table 1: WPT systems within the permitted frequency bands below 30 MHz
WPT frequency range Frequency Bands Applications
Transmit and Receive 1 19 kHz to 21 kHz WPT systems
Transmit and Receive 2 59 kHz to 61 kHz WPT systems
Transmit and Receive 3 79 kHz to 90 kHz WPT systems
Transmit and Receive 100 kHz to 119 kHz WPT systems
Transmit and Receive 119 kHz to 140 kHz WPT systems
Transmit and Receive 140 kHz to 148,5 kHz WPT systems
Transmit and Receive 148,5 kHz to 300 kHz WPT systems
Transmit and Receive 5 6 765 kHz to 6 795 kHz WPT systems
NOTE 1: The frequency ranges listed in Table 1 are also used for generic inductive short range devices, according
to ETSI EN 300 330 [1].
NOTE 2: The limits and the frequency ranges of the present document are EU wide harmonised according to
EC Decision 2013/752/EU [i.2] and ERC/REC 70-03 [i.1].
NOTE 3: In addition, it should be noted that other frequency bands may be available in a country within the
frequency range below 30 MHz.
The present document covers the essential requirements of article 3.2 of Directive 2014/53/EU [i.3] under the
conditions identified in Annex A.

A WPT system always consists of a base station and a mobile device which are in proximity to each other. The
performance of a WPT system is dependent on the related operational mode, see clause 4.2.3.
For the purpose of the receiver performance tests, the WPT system shall produce an appropriate output under normal
conditions as indicated below:
• use as intended without degradation of performance; or
• a degradation of the performance is indicated by the WPT system as described in the manual.
The manufacturer shall declare the performance criteria used to determine the performance of the receiving parts inside
the WPT system (related to the mode).
4.2.3 WPT operational modes
Because of the close interaction between base station and mobile device the manufacturer shall provide all necessary
parts for the presentation of equipment and for testing purposes. The description of the setup including the positioning
and mechanical orientation of both parts shall be provided since this affects the radiated emissions. For using different
batteries or power receiving parts with one base station, the manufacturer shall declare the typical and the worst case
combinations with regard to radiated emissions and provide such combinations for testing.
In certain cases it may be not possible to provide samples of all possible mobile devices due to unavailability. In these
cases the manufacturer has to declare that the base station was developed based on certain mobile devices and such base
station/mobile device combinations shall be provided for testing.
The manufacturer shall declare for each possible operation mode of the WPT system (overview see Table 2):
a) charging mode/power transmission/system in resonance;
b) communication mode (data transmission from and to the mobile device);
c) determination of the charging action e.g. to find the resonance frequency of the system or optimal charging
parameters of the WPT systems.
Additional declarations to establish the appropriate test conditions:
a) the mechanical setup/alignment;
b) the maximum allowed values for the x-y-z offset within the alignment (worst-case alignment);
c) the mechanical orientation;
d) the permitted range of frequencies;
e) the range of operating conditions including the duty cycle or pulsing operational parameter;
f) power requirements;
g) information about which part of the WPT System can be interpreted as transmitter (mode dependent).
The measurements itself shall be done on these actual set-up and operating conditions for each mode.

NOTE: If during the initial establishment of the charging mode (mode 2 from Table 2), no or very low emission
occur (below the sensitivity level of the test set-up), then this initialization mode can be assumed as
irrelevant for the test.

4.2.4 Presentation of equipment for testing purposes
4.2.4.1 General
Each WPT system submitted for testing shall fulfil the requirements of the present document on all frequencies over
which it is intended to operate.
The manufacturer shall declare the permitted frequency ranges (see clause 4.4.2), the range of operating conditions and
power requirements as applicable, to establish the appropriate test conditions.
Additionally, technical documentation and operating manuals, sufficient to make the test, shall be supplied.
If a WPT system is designed to operate with different system mode (see clause 4.2.3), measurement of each mode shall
be performed, according to the present document, on samples of equipment defined in clause 4.2.4.2.
To simplify and harmonize the testing procedures between different testing laboratories, measurements shall be
performed, according to the present document, on samples defined in clauses 4.2.4.2 to 4.2.4.4.
4.2.4.2 Choice of model for testing
The manufacturer shall provide one or more samples of the WPT system, as appropriate for testing.
Standalone WPT systems shall be offered by the manufacturer complete with any ancillary equipment needed for
testing.
If a WPT system has several optional features, considered not to affect the emission parameters then the tests need only
to be performed on the WPT system configured with that combination of features considered to be the most complex, as
proposed by the manufacturer and agreed by the test laboratory.
The performance of the WPT system submitted for testing shall be representative of the performance of the
corresponding production model.
4.2.4.3 Testing of WPT systems
If a family of WPT systems has alternative radiated field strengths provided by the use of separate power modules or
add on stages, then these shall be declared by the manufacturer. Each module or add on stage shall be tested in
combination with the equipment. As a minimum, measurements of the radiated H-field strength and spurious emissions
shall be performed for each combination and shall be stated in the test report.
The manufacturer has to submit the necessary parts as base station and mobile device for the test. The test shall be done
in the worst case setup/mechanical arrangement.
4.2.4.4 On-site testing
In certain cases it may not be possible to provide representative samples of antennas and/or equipment due to physical
constraints. In these cases equivalent measurements to the present document shall be made at a representative
installation of the equipment (on-site).
4.2.5 Mechanical and electrical design
4.2.5.1 General

accessible to the user.
ETSI
15 Final draft ETSI EN 303 417 V1.1.1 (2017-06)
4.2.5.3 Shut-off facility
If the WPT system is equipped with an automatic shut-off facility (for communication and/or power transmission), it
should be made inoperative for the duration of the test.
If this would be not possible, e.g. to avoid the damage of the battery, the test shall be performed during normal
operation.
4.3 Transmitter conformance requirements
4.3.1 General
A WPT system could work in different mode (see clause 4.2.3, Table 2) and this could influence the radiated emission.
Depending on the operation mode of the WPT system the manufacturer has to declare the operational modes (e.g.
combination base station/mobile device or stand-alone base station), see clause 4.2.3, Table 2. The emission test shall
be performed for all operational modes (see Table 2).
4.3.2 Permitted range of operating frequencies
4.3.2.1 Applicability
This applies to all WPT systems.
4.3.2.2 Description

Introduction
The present document has been prepared to conform to the requirements of the new Radio Equipment Directive
2014/53/EU [i.3]. The present document covers wireless power transmission (WPT) systems using technologies other
than radio frequency beam in the frequency ranges 19 - 21 kHz, 59 - 61 kHz, 79 - 90 kHz, 100 - 300 kHz,
6 765 - 6 795 kHz.
In the context of the present document "power transmission via radio frequency beam" means power transmission by
radio waves.
For the clarification of open questions for high power wireless power transmission systems to charge vehicles a SRdoc
ETSI TR 103 409 [i.4] was prepared. New specific requirements for such systems (e.g. higher H-field emission limits in
the 79 - 90 kHz band) will be reflected within a future revision of the present document.
The present document is structured as follows:
Clauses 1 through 3 provide a general description on the types of equipment covered by the present document and the
definitions, symbols and abbreviations used.
Clause 4 provides the technical requirements specifications, limits and conformance relative to transmitter and receiver.
Clause 5 specifies the conditions for testing of the equipment and interpretation of the measurement results with the
maximum measurement uncertainty values.
Clause 6 specifies the required measurement methods.
Annex A (informative) provides the relationship between the present document and the essential requirements of
Directive 2014/53/EU [i.3].
Annex B (normative) provides the measurement setup specifically for Electric Vehicles.
ETSI

1 Scope
The present document specifies technical characteristics and methods of measurements for wireless power transmission
(WPT) systems, using technologies other than radio frequency beam, in the 19 - 21 kHz, 59 - 61 kHz, 79 - 90 kHz,
100 - 300 kHz, 6 765 - 6 795 kHz ranges.
The present document covers wireless power transmission systems which are regarded as radio equipment since
including inherent radio communication functionality or radiodetermination via the WPT interface or port at the specific
WPT frequency ranges.
Such systems usually consist of:
1) A power transmitter, with additional communication capability to control the charge function, in conjunction
with the receiving part. The power transmitter could also be named as base station.
2) A power receiver, which supplies the received energy to a mobile device and performs a control/supervision
function for the mobile device status and charge operation.
Both parts in combination are able to transmit and receive data in addition to the power transmission mode e.g. to
control the mobile device status and to optimize the power transmission mode.
These radio equipment types are capable of operating in the permitted frequency bands below 30 MHz as specified in
Table 1.
The present document covers fixed systems, mobile and portable systems.

4.2 General
4.2.1 Background information
In this clause all general considerations for the testing of wireless power transmission (WPT) systems using
technologies other than radio frequency beam in the 19 - 21 kHz, 59 - 61 kHz, 79 - 90 kHz, 100 - 300 kHz,
6 765 - 6 795 kHz ranges are given. The tests cover all different operational modes, as described in clause 4.2.3.
4.2.2 Wanted performance criteria
A WPT system always consists of a base station and a mobile device which are in proximity to each other. The
performance of a WPT system is dependent on the related operational mode, see clause 4.2.3.
For the purpose of the receiver performance tests, the WPT system shall produce an appropriate output under normal
conditions as indicated below:
• use as intended without degradation of performance; or
• a degradation of the performance is indicated by the WPT system as described in the manual.
The manufacturer shall declare the performance criteria used to determine the performance of the receiving parts inside
the WPT system (related to the mode).
4.2.3 WPT operational modes
Because of the close interaction between base station and mobile device the manufacturer shall provide all necessary
parts for the presentation of equipment and for testing purposes. The description of the setup including the positioning
and mechanical orientation of both parts shall be provided since this affects the radiated emissions. For using different
batteries or power receiving parts with one base station, the manufacturer shall declare the typical and the worst case
combinations with regard to radiated emissions and provide such combinations for testing.
In certain cases it may be not possible to provide samples of all possible mobile devices due to unavailability. In these
cases the manufacturer has to declare that the base station was developed based on certain mobile devices and such base
station/mobile device combinations shall be provided for testing.
The manufacturer shall declare for each possible operation mode of the WPT system (overview see Table 2):
a) charging mode/power transmission/system in resonance;
b) communication mode (data transmission from and to the mobile device);
c) determination of the charging action e.g. to find the resonance frequency of the system or optimal charging
parameters of the WPT systems.
Additional declarations to establish the appropriate test conditions:
a) the mechanical setup/alignment;
b) the maximum allowed values for the x-y-z offset within the alignment (worst-case alignment);
c) the mechanical orientation;
d) the permitted range of frequencies;
e) the range of operating conditions including the duty cycle or pulsing operational parameter;
f) power requirements;
g) information about which part of the WPT System can be interpreted as transmitter (mode dependent).
The measurements itself shall be done on these actual set-up and operating conditions for each mode.
ETSI
12 ETSI EN 303 417 V1.1.1 (2017-09)
NOTE: If during the initial establishment of the charging mode (mode 2 from Table 2), no or very low emission
occur (below the sensitivity level of the test set-up), then this initialization mode can be assumed as
irrelevant for the test.

If a WPT system has several optional features, considered not to affect the emission parameters then the tests need only
to be performed on the WPT system configured with that combination of features considered to be the most complex, as
proposed by the manufacturer and agreed by the test laboratory.
The performance of the WPT system submitted for testing shall be representative of the performance of the
corresponding production model.
4.2.4.3 Testing of WPT systems
If a family of WPT systems has alternative radiated field strengths provided by the use of separate power modules or
add on stages, then these shall be declared by the manufacturer. Each module or add on stage shall be tested in
combination with the equipment. As a minimum, measurements of the radiated H-field strength and spurious emissions
shall be performed for each combination and shall be stated in the test report.

ETSI ETSI EN 303 417 V1.1.1 (2017-09) 6 Introduction The present document has been prepared to conform to the requirements of the new Radio Equipment Directive 2014/53/EU [i.3]. The present document covers wireless power transmission (WPT) systems using technologies other than radio frequency beam in the frequency ranges 19 - 21 kHz, 59 - 61 kHz, 79 - 90 kHz, 100 - 300 kHz, 6 765 - 6 795 kHz. In the context of the present document "power transmission via radio frequency beam" means power transmission by radio waves. For the clarification of open questions for high power wireless power transmission systems to charge vehicles a SRdoc ETSI TR 103 409 [i.4] was prepared. New specific requirements for such systems (e.g. higher H-field emission limits in the 79 - 90 kHz band) will be reflected within a future revision of the present document.
The present document is structured as follows: Clauses 1 through 3 provide a general description on the types of equipment covered by the present document and the definitions, symbols and abbreviations used. Clause 4 provides the technical requirements specifications, limits and conformance relative to transmitter and receiver. Clause 5 specifies the conditions for testing of the equipment and interpretation of the measurement results with the maximum measurement uncertainty values. Clause 6 specifies the required measurement methods. Annex A (informative) provides the relationship between the present document and the essential requirements of Directive 2014/53/EU [i.3]. Annex B (normative) provides the measurement setup specifically for Electric Vehicles.
ETSI ETSI EN 303 417 V1.1.1 (2017-09) 7 1 Scope The present document specifies technical characteristics and methods of measurements for wireless power transmission (WPT) systems, using technologies other than radio frequency beam, in the 19 - 21 kHz, 59 - 61 kHz, 79 - 90 kHz, 100 - 300 kHz, 6 765 - 6 795 kHz ranges. The present document covers wireless power transmission systems which are regarded as radio equipment since including inherent radio communication functionality or radiodetermination via the WPT interface or port at the specific WPT frequency ranges. Such systems usually consist of:
1) A power transmitter, with additional communication capability to control the charge function, in conjunction with the receiving part. The power transmitter could also be named as base station. 2) A power receiver, which supplies the received energy to a mobile device and performs a control/supervision function for the mobile device status and charge operation. Both parts in combination are able to transmit and receive data in addition to the power transmission mode e.g. to control the mobile device status and to optimize the power transmission mode. These radio equipment types are capable of operating in the permitted frequency bands below 30 MHz as specified in Table 1. The present document covers fixed systems, mobile and portable systems.

The manufacturer shall declare the permitted frequency ranges (see clause 4.3.2), the range of operating conditions and power requirements as applicable, to establish the appropriate test conditions. Additionally, technical documentation and operating manuals, sufficient to make the test, shall be supplied. If a WPT system is designed to operate with different system mode (see clause 4.2.3), measurement of each mode shall be performed, according to the present document, on samples of equipment defined in clause 4.2.4.2. To simplify and harmonize the testing procedures between different testing laboratories, measurements shall be performed, according to the present document, on samples defined in clauses 4.2.4.2 to 4.2.4.4. 4.2.4.2 Choice of model for testing The manufacturer shall provide one or more samples of the WPT system, as appropriate for testing. Standalone WPT systems shall be offered by the manufacturer complete with any ancillary equipment needed for testing. If a WPT system has several optional features, considered not to affect the emission parameters then the tests need only to be performed on the WPT system configured with that combination of features considered to be the most complex, as proposed by the manufacturer and agreed by the test laboratory. The performance of the WPT system submitted for testing shall be representative of the performance of the corresponding production model. 4.2.4.3 Testing of WPT systems If a family of WPT systems has alternative radiated field strengths provided by the use of separate power modules or add on stages, then these shall be declared by the manufacturer. Each module or add on stage shall be tested in combination with the equipment. As a minimum, measurements of the radiated H-field strength and spurious emissions shall be performed for each combination and shall be stated in the test report. The manufacturer has to submit the necessary parts as base station and mobile device for the test. The test shall be done in the worst case setup/mechanical arrangement. 4.2.4.4 On-site testing In certain cases it may not be possible to provide representative samples of antennas and/or equipment due to physical constraints. In these cases equivalent measurements to the present document shall be made at a representative installation of the equipment (on-site). 4.2.5 Mechanical and electrical design 4.2.5.1 General Based on the possible operation mode declared by the manufacturer (see clause 4.2.3) the transmitter (base station) and receiver (mobile device or mobile device emulator) shall be tested as described in clause 4.2.3, Table 2. 4.2.5.2 Controls Those controls which, if maladjusted, might increase the interfering potentialities of the equipment shall not be easily accessible to the user.

If this would be not possible, e.g. to avoid the damage of the battery, the test shall be performed during normal operation. 4.3 Transmitter conformance requirements 4.3.1 General A WPT system could work in different mode (see clause 4.2.3, Table 2) and this could influence the radiated emission. Depending on the operation mode of the WPT system the manufacturer has to declare the operational modes (e.g. combination base station/mobile device or stand-alone base station), see clause 4.2.3, Table 2. The emission test shall be performed for all operational modes (see Table 2). 4.3.2 Permitted range of operating frequencies 4.3.2.1 Applicability This applies to all WPT systems. 4.3.2.2 Description The permitted range of operating frequencies denotes the frequency ranges set out in Table 1.

The justification/test shall be performed for Operating frequency ranges, see clause 4.3.3. 4.3.3 Operating frequency range(s) (OFR) 4.3.3.1 Applicability This applies to all WPT systems. 4.3.3.2 Description The operating frequency range is the frequency range over which the WPT system is intentionally transmitting (all operational modes, see clause 4.2.3, Table 2). The operating frequency range(s) of the WPT system are determined by the lowest (fL) and highest frequency (fH) as occupied by the power envelope. The WPT system could have more than one operating frequency range. For a single frequency systems the OFR is equal to the occupied bandwidth (OBW) of the WPT system. For multi-frequency systems the OFR is described in Figures 2 and 3. SIST EN 303 417 V1.1.1:2017
