4 Applicability of Radio Parameters
4.1 General

The essential requirements of the Radio Equipment Directive are general and do not identify specific design criteria.

ETSI HSs define criteria for fulfilling the essential requirements by providing applicable radio parameters for the

development and manufacturing of radio equipment.

The TB should identify the parameters and/or tests necessary to be specified in an HS for the radio system under

consideration to fulfil the essential requirements in article 3.2 of Directive 2014/53/EU [i.1] by considering the radio

parameters in the following clauses of the present document.

The parameters in clause 5 of the present document are the minimal set TBs should consider including in HSs. These

parameters are relevant for most equipment, but TBs may consider including additional parameters where relevant. The

order of the parameters is not significant.

TBs not including one or more of the parameters in clause 5, or including additional parameters, should include a

technical justification of such deviation from the present document in the HS or in a referenced separate ETSI

deliverable.

The guidance in clause 6 applies when producing an HS under article 3.1(b) of Directive 2014/53/EU [i.1] covering the

ElectroMagnetic Compatibility (EMC) aspects of radio equipment.

Any differences from terminology used in the present document should be clarified in the HS or in a separate ETSI

deliverable.

When drafting HSs, relevant ETSI TBs should take into consideration all applicable CEPT/ECC deliverables.

4.2 Additional Information required
4.2.1 Operating frequency range

The operating frequency range consists of the radio frequency band(s) over which the transmitter and receiver operate

in accordance with the intended use of the equipment, as referred to in Article 10(8) of the Radio Equipment

Directive [i.1]:

"Manufacturers shall ensure that the radio equipment is accompanied by instructions and safety information in a

language which can be easily understood by consumers and other end-users, as determined by the Member State

concerned. Instructions shall include the information required to use radio equipment in accordance with its

intended use. …

The following information shall also be included in the case of radio equipment intentionally emitting radio waves:

(a) frequency band(s) in which the radio equipment operates;

(b) maximum radio-frequency power transmitted in the frequency band(s) in which the radio equipment operates."

However, this type of information is not part of the normative requirements included in the HSs covering article 3.1(b)

and article 3.2 of Directive 2014/53/EU, which are within the scope of the present document.

4.2.2 Other information

At the discretion of the TB, other information may be required, for example to facilitate testing. Informative annexes

may be included where appropriate.

TBs should not include requirements for manufacturers declarations within the normative part of HSs.

10 ETSI EG 203 336 V1.2.1 (2020-05)
5 Technical parameters for article 3.2 of Directive
2014/53/EU
5.1 General

Harmonised Standards (HSs) are not intended to specify how products are designed but how they respond in the

presence of various external stimuli (simulating other spectrum users and interference). An EUT in an HS should be

regarded as a "black box".

Some equipment may implement features relevant to article 3.2 using embedded software. Where appropriate, TBs

should include provisions in an HS that prevent unintended configurations potentially leading to non-conformity with

article 3.2.

An "Environmental Profile" clause should be included which indicates that technical requirements should be met

throughout the environmental conditions indicated in the HS. Example text is provided in the skeleton document for

HSs available from the ETSI web site.

The Radio Equipment Directive (RED) does not contain an equivalent of "Essential Radio Test Suites" from annex III

of Directive 1999/5/EC [i.8]. Nevertheless, in order to ensure repeatability, HSs should specify, when necessary, test

procedures and corresponding test conditions.
5.2 Transmitter parameters under article 3.2 of Directive
2014/53/EU
5.2.1 General
The essential requirement in article 3.2 of Directive 2014/53/EU [i.1] states:

"Radio equipment shall be so constructed that it both effectively uses and supports the efficient use of radio spectrum in

order to avoid harmful interference."

When deciding which transmitter parameters to include in the HS, TBs should consider both in-band and adjacent-band.

Relevant Electronic Communications Committee (ECC) and/or European Union (EU) deliverables may provide useful

information.

In order to facilitate the application of HSs, the technical conditions attached to spectrum regulations (including

conditions to support a general licence) should be taken into consideration when drafting the HS compliance conditions.

Justification for the requirements in relation to transmitters is given by recital 10 of the Directive which states:

"…when the transmitter is properly installed, maintained and used for its intended purpose it generates radio waves

emissions that do not create harmful interference, while unwanted radio waves emissions generated by the transmitter

(e.g. in adjacent channels) with a potential negative impact on the goals of radio spectrum policy should be limited to

such a level that, according to the state of the art, harmful interference is avoided;"

Some equipment types may have a number of different operational transmission modes with different spectrum usages.

The HS should be developed such that compliance with the essential requirements is ensured when operating in any

operational mode.
5.2.2 Transmitter power limits

HSs may include transmitter power limits. However, TBs should note that these are defined in national Radio Interface

Specifications (RIS) and also in individual or general licence authorizations. Furthermore, TBs should be aware that

there may be relevant ECC and EU deliverables.

The transmitter power limits may include a minimum range of Transmitter Power Control (TPC) (see clause 5.4 on

interference mitigation techniques).
ETSI
---------------------- Page: 10 ----------------------
11 ETSI EG 203 336 V1.2.1 (2020-05)

Transmitter power limits may be specified and measured using a "spectrum mask" (clause 5.2.4) or as a total power in

the transmit channel.

For devices without an antenna connector, the maximum power allowed may be specified as Total Radiated Power,

ERP or EIRP.

4 Applicability of Radio Parameters
4.1 General

The essential requirements of the Radio Equipment Directive are general and do not identify specific design criteria.

ETSI HSs define criteria for fulfilling the essential requirements by providing applicable radio parameters for the

development and manufacturing of radio equipment.

The TB should identify the parameters and/or tests necessary to be specified in an HS for the radio system under

consideration to fulfil the essential requirements in article 3.2 of Directive 2014/53/EU [i.1] by considering the radio

parameters in the following clauses of the present document.

The parameters in clause 5 of the present document are the minimal set TBs should consider including in HSs. These

parameters are relevant for most equipment, but TBs may consider including additional parameters where relevant. The

order of the parameters is not significant.

TBs not including one or more of the parameters in clause 5, or including additional parameters, should include a

technical justification of such deviation from the present document in the HS or in a referenced separate ETSI

deliverable.

The guidance in clause 6 applies when producing an HS under article 3.1(b) of Directive 2014/53/EU [i.1] covering the

ElectroMagnetic Compatibility (EMC) aspects of radio equipment.

Any differences from terminology used in the present document should be clarified in the HS or in a separate ETSI

deliverable.

When drafting HSs, relevant ETSI TBs should take into consideration all applicable CEPT/ECC deliverables.

4.2 Additional Information required
4.2.1 Operating frequency range

The operating frequency range consists of the radio frequency band(s) over which the transmitter and receiver operate

in accordance with the intended use of the equipment, as referred to in Article 10(8) of the Radio Equipment

Directive [i.1]:

"Manufacturers shall ensure that the radio equipment is accompanied by instructions and safety information in a

language which can be easily understood by consumers and other end-users, as determined by the Member State

concerned. Instructions shall include the information required to use radio equipment in accordance with its

intended use. …

The following information shall also be included in the case of radio equipment intentionally emitting radio waves:

(a) frequency band(s) in which the radio equipment operates;

(b) maximum radio-frequency power transmitted in the frequency band(s) in which the radio equipment operates."

However, this type of information is not part of the normative requirements included in the HSs covering article 3.1(b)

and article 3.2 of Directive 2014/53/EU, which are within the scope of the present document.

4.2.2 Other information

At the discretion of the TB, other information may be required, for example to facilitate testing. Informative annexes

may be included where appropriate.

TBs should not include requirements for manufacturers declarations within the normative part of HSs.

5 Technical parameters for article 3.2 of Directive
2014/53/EU
5.1 General

Harmonised Standards (HSs) are not intended to specify how products are designed but how they respond in the

presence of various external stimuli (simulating other spectrum users and interference). An EUT in an HS should be

regarded as a "black box".

Some equipment may implement features relevant to article 3.2 using embedded software. Where appropriate, TBs

should include provisions in an HS that prevent unintended configurations potentially leading to non-conformity with

article 3.2.

An "Environmental Profile" clause should be included which indicates that technical requirements should be met

throughout the environmental conditions indicated in the HS. Example text is provided in the skeleton document for

HSs available from the ETSI web site.

The Radio Equipment Directive (RED) does not contain an equivalent of "Essential Radio Test Suites" from annex III

of Directive 1999/5/EC [i.8]. Nevertheless, in order to ensure repeatability, HSs should specify, when necessary, test

procedures and corresponding test conditions.
5.2 Transmitter parameters under article 3.2 of Directive
2014/53/EU
5.2.1 General
The essential requirement in article 3.2 of Directive 2014/53/EU [i.1] states:

"Radio equipment shall be so constructed that it both effectively uses and supports the efficient use of radio spectrum in

order to avoid harmful interference."

When deciding which transmitter parameters to include in the HS, TBs should consider both in-band and adjacent-band.

Relevant Electronic Communications Committee (ECC) and/or European Union (EU) deliverables may provide useful

information.

In order to facilitate the application of HSs, the technical conditions attached to spectrum regulations (including

conditions to support a general licence) should be taken into consideration when drafting the HS compliance conditions.

Justification for the requirements in relation to transmitters is given by recital 10 of the Directive which states:

"…when the transmitter is properly installed, maintained and used for its intended purpose it generates radio waves

emissions that do not create harmful interference, while unwanted radio waves emissions generated by the transmitter

(e.g. in adjacent channels) with a potential negative impact on the goals of radio spectrum policy should be limited to

such a level that, according to the state of the art, harmful interference is avoided;"

Some equipment types may have a number of different operational transmission modes with different spectrum usages.

The HS should be developed such that compliance with the essential requirements is ensured when operating in any

operational mode.
5.2.2 Transmitter power limits

HSs may include transmitter power limits. However, TBs should note that these are defined in national Radio Interface

Specifications (RIS) and also in individual or general licence authorizations. Furthermore, TBs should be aware that

there may be relevant ECC and EU deliverables.

The transmitter power limits may include a minimum range of Transmitter Power Control (TPC) (see clause 5.4 on

interference mitigation techniques).

4 Applicability of Radio Parameters
4.1 General

The essential requirements of the Radio Equipment Directive are general and do not identify specific design criteria.

ETSI HSs define criteria for fulfilling the essential requirements by providing applicable radio parameters for the

development and manufacturing of radio equipment.

The TB should identify the parameters and/or tests necessary to be specified in an HS for the radio system under

consideration to fulfil the essential requirements in article 3.2 of Directive 2014/53/EU [i.1] by considering the radio

parameters in the following clauses of the present document.

The parameters in clause 5 of the present document are the minimal set TBs should consider including in HSs. These

parameters are relevant for most equipment, but TBs may consider including additional parameters where relevant. The

order of the parameters is not significant.

TBs not including one or more of the parameters in clause 5, or including additional parameters, should include a

technical justification of such deviation from the present document in the HS or in a referenced separate ETSI

deliverable.

The guidance in clause 6 applies when producing an HS under article 3.1(b) of Directive 2014/53/EU [i.1] covering the

ElectroMagnetic Compatibility (EMC) aspects of radio equipment.

Any differences from terminology used in the present document should be clarified in the HS or in a separate ETSI

deliverable.

When drafting HSs, relevant ETSI TBs should take into consideration all applicable CEPT/ECC deliverables.

4.2 Additional Information required
4.2.1 Operating frequency range

The operating frequency range consists of the radio frequency band(s) over which the transmitter and receiver operate

in accordance with the intended use of the equipment, as referred to in Article 10(8) of the Radio Equipment

Directive [i.1]:

"Manufacturers shall ensure that the radio equipment is accompanied by instructions and safety information in a

language which can be easily understood by consumers and other end-users, as determined by the Member State

concerned. Instructions shall include the information required to use radio equipment in accordance with its

intended use. …

The following information shall also be included in the case of radio equipment intentionally emitting radio waves:

(a) frequency band(s) in which the radio equipment operates;

(b) maximum radio-frequency power transmitted in the frequency band(s) in which the radio equipment operates."

However, this type of information is not part of the normative requirements included in the HSs covering article 3.1(b)

and article 3.2 of Directive 2014/53/EU, which are within the scope of the present document.

4.2.2 Other information

At the discretion of the TB, other information may be required, for example to facilitate testing. Informative annexes

may be included where appropriate.

TBs should not include requirements for manufacturers declarations within the normative part of HSs.

5 Technical parameters for article 3.2 of Directive
2014/53/EU
5.1 General

Harmonised Standards (HSs) are not intended to specify how products are designed but how they respond in the

presence of various external stimuli (simulating other spectrum users and interference). An EUT in an HS should be

regarded as a "black box".

Some equipment may implement features relevant to article 3.2 using embedded software. Where appropriate, TBs

should include provisions in an HS that prevent unintended configurations potentially leading to non-conformity with

article 3.2.

An "Environmental Profile" clause should be included which indicates that technical requirements should be met

throughout the environmental conditions indicated in the HS. Example text is provided in the skeleton document for

HSs available from the ETSI web site.

The Radio Equipment Directive (RED) does not contain an equivalent of "Essential Radio Test Suites" from annex III

of Directive 1999/5/EC [i.8]. Nevertheless, in order to ensure repeatability, HSs should specify, when necessary, test

procedures and corresponding test conditions.
5.2 Transmitter parameters under article 3.2 of Directive
2014/53/EU
5.2.1 General
The essential requirement in article 3.2 of Directive 2014/53/EU [i.1] states:

"Radio equipment shall be so constructed that it both effectively uses and supports the efficient use of radio spectrum in

order to avoid harmful interference."

When deciding which transmitter parameters to include in the HS, TBs should consider both in-band and adjacent-band.

Relevant Electronic Communications Committee (ECC) and/or European Union (EU) deliverables may provide useful

information.

In order to facilitate the application of HSs, the technical conditions attached to spectrum regulations (including

conditions to support a general licence) should be taken into consideration when drafting the HS compliance conditions.

Justification for the requirements in relation to transmitters is given by recital 10 of the Directive which states:

"…when the transmitter is properly installed, maintained and used for its intended purpose it generates radio waves

emissions that do not create harmful interference, while unwanted radio waves emissions generated by the transmitter

(e.g. in adjacent channels) with a potential negative impac
