Intelligent Transport Systems (ITS) - Radiocommunications equipment operating in the 5 855 MHz to 5 925 MHz frequency band - Harmonised Standard covering the essential requirements of article 3.2 of Directive 2014/53/EU
The present document specifies technical characteristics and methods of measurement for radio transmitters and
receivers operating in the frequency range 5 855 MHz to 5 925 MHz. The spectrum usage conditions are set out in
ECC Decision (08)01 [i.1] for the frequency range 5 875 MHz to 5 925 MHz (with 5 905 MHz to 5 925 MHz
considered as a future ITS extension) and in ECC Recommendation (08)01 [i.2] for the frequency range 5 855 MHz
to 5 875 MHz. The Commission Decision 2008/671/EC [i.3] mandates a harmonised use of the frequency band
5 875 MHz to 5 905 MHz dedicated to safety-related applications of ITS throughout the member states of the European
Union. Table 1 outlines the 5 GHz ITS frequency band segmentation.
Inteligentni transportni sistemi (ITS) - Radiokomunikacijska oprema, ki deluje v frekvenčnem pasu od 5855 MHz do 5925 MHz - Harmonizirani standard, ki zajema bistvene zahteve člena 3.2 direktive 2014/53/EU
Ta dokument določa tehnične karakteristike in merilne metode za radijske oddajnike in sprejemnike, ki delujejo v frekvenčnem območju od 5855 MHz do 5925 MHz. Pogoji uporabe spektra so določeni v odločbi ECC (08)01 [i.1] za frekvenčno območje od 5875 MHz do 5925 MHz (pri čemer se 5905 MHz do 5925 MHz obravnava kot prihodnja razširitev ITS) in priporočilu ECC (08)01 [i.2] za frekvenčno območje od 5855 MHz do 5875 MHz. Odločba Komisije 2008/671/ES [i.3] predpisuje usklajeno uporabo frekvenčnega pasu od 5875 MHz do 5905 MHz, namenjenega za z varnostjo povezane vrste uporabe ITS v državah članicah Evropske unije. V preglednici 1 je prikazana segmentacija frekvenčnega pasu 5 GHz ITS.

1 Scope
The present document applies to radio transmitters and receivers for Intelligent Transport Systems (ITS) operating in
the frequency range 5 855 GHz to 5 925 GHz. The spectrum usage conditions are set out in ECC Decision (08)01 [i.1]
for the frequency range 5 875 GHz to 5 925 GHz and in ECC Recommendation (08)01 [i.2] for the frequency range
5 855 GHz to 5 875 GHz. The Commission Decision 2008/671/EC [i.3] mandates a harmonised use of the frequency
band 5 875 GHz to 5 905 GHz dedicated to safety-related applications of ITS throughout the member states of the
European Union. Table 1 outlines the 5 GHz ITS frequency band segmentation.

Foreword
This final draft Harmonised European Standard (EN) 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 EN Approval Procedure.
The present document has been prepared under the Commission's standardisation request C(2015) 5376 final [i.5] to
provide one voluntary means of conforming to the essential requirements of Directive 2014/53/EU on the harmonisation
of the laws of the Member States relating to the making available on the market of radio equipment and repealing
Directive 1999/5/EC [i.4].
Once the present document is cited in the Official Journal of the European Union under that Directive, compliance with
the normative clauses of the present document given in Table A.1 confers, within the limits of the scope of the present
document, a presumption of conformity with the corresponding essential requirements of that Directive, and associated
EFTA regulations.

1 Scope
The present document specifies technical characteristics and methods of measurement for radio transmitters and
receivers operating in the frequency range 5 855 MHz to 5 925 MHz. The spectrum usage conditions are set out in
ECC Decision (08)01 [i.1] for the frequency range 5 875 MHz to 5 925 MHz (with 5 905 MHz to 5 925 MHz
considered as a future ITS extension) and in ECC Recommendation (08)01 [i.2] for the frequency range 5 855 MHz
to 5 875 MHz. The Commission Decision 2008/671/EC [i.3] mandates a harmonised use of the frequency band
5 875 MHz to 5 905 MHz dedicated to safety-related applications of ITS throughout the member states of the European
Union. Table 1 outlines the 5 GHz ITS frequency band segmentation.

The present document covers the essential requirements of article 3.2 of Directive 2014/53/EU [i.4] under the
conditions identified in annex A.
Interference mitigation techniques in the present document are provided to protect road tolling applications using CEN
DSRC or HDR DSRC.

1 Scope
The present document specifies technical characteristics and methods of measurement for radio transmitters and
receivers operating in the frequency range 5 855 MHz to 5 925 MHz. The spectrum usage conditions are set out in
ECC Decision (08)01 [i.1] for the frequency range 5 875 MHz to 5 925 MHz (with 5 905 MHz to 5 925 MHz
considered as a future ITS extension) and in ECC Recommendation (08)01 [i.2] for the frequency range 5 855 MHz
to 5 875 MHz. The Commission Decision 2008/671/EC [i.3] mandates a harmonised use of the frequency band
5 875 MHz to 5 905 MHz dedicated to safety-related applications of ITS throughout the member states of the European
Union. Table 1 outlines the 5 GHz ITS frequency band segmentation.

The present document covers the essential requirements of article 3.2 of Directive 2014/53/EU [i.4] under the
conditions identified in annex A.
Interference mitigation techniques in the present document are provided to protect road tolling applications using CEN

ETSI ETSI EN 302 571 V2.1.1 (2017-02) 8 1 Scope The present document specifies technical characteristics and methods of measurement for radio transmitters and receivers operating in the frequency range 5 855 MHz to 5 925 MHz. The spectrum usage conditions are set out in ECC Decision (08)01 [i.1] for the frequency range 5 875 MHz to 5 925 MHz (with 5 905 MHz to 5 925 MHz considered as a future ITS extension) and in ECC Recommendation (08)01 [i.2] for the frequency range 5 855 MHz to 5 875 MHz. The Commission Decision 2008/671/EC [i.3] mandates a harmonised use of the frequency band 5 875 MHz to 5 905 MHz dedicated to safety-related applications of ITS throughout the member states of the European Union. Table 1 outlines the 5 GHz ITS frequency band segmentation.
