Foreword

This 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 combined Public Enquiry and 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.3] 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.2].

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.

The present document is part 2, sub-part 2 of a multi-part deliverable covering Transport and Traffic Telematics (TTT);

Dedicated Short Range Communication (DSRC) transmission equipment (500 kbit/s / 250 kbit/s) operating in the

5 795 MHz to 5 815 MHz frequency band, as identified below:

Part 1: "General characteristics and test methods for Road Side Units (RSU) and On-Board Units (OBU)";

Part 2: "Harmonised Standard for access to radio spectrum";
Sub-part 1: "Road Side Units (RSU)";
Sub-part 2: "On-Board Units (OBU)".
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

1 Scope

The present document specifies technical characteristics and methods of measurements for Transport and Traffic

Telematics (TTT) systems:

• with a Radio Frequency (RF) output connection and specified antenna or with an integral antenna;

• for data transmission only;
• operating in the 5 795 MHz to 5 815 MHz frequency band.
The applicability of the present document covers only the On Board Units (OBU).

The present document complies with the Commission Implementing Decision 2017/1483/EU [i.4] and CEPT/ERC

Recommendation 70-03 [i.6].

The present document applies to the following radio equipment types operating in all or in part of the following service

frequency bands given in table 1.
Table 1: Frequency bands and centre frequencies f allocated for DSRC
Pan European Service Frequencies National Service Frequencies
Channel 1 5,795 GHz to 5,800 GHz, f = 5,7975 GHz
Channel 2 5,800 GHz to 5,805 GHz, f = 5,8025 GHz
Channel 3 5,805 GHz to 5,810 GHz, f = 5,8075 GHz
Channel 4 5,810 GHz to 5,815 GHz, f = 5,8125 GHz

IPRs essential or potentially essential to normative deliverables may have been declared to ETSI. The information

pertaining to these essential IPRs, if any, is publicly available for ETSI members and non-members, and can be found

in ETSI SR 000 314: "Intellectual Property Rights (IPRs); Essential, or potentially Essential, IPRs notified to ETSI in

respect of ETSI standards", which is available from the ETSI Secretariat. Latest updates are available on the ETSI Web

server (https://ipr.etsi.org/).

Pursuant to the ETSI IPR Policy, no investigation, including IPR searches, has been carried out by ETSI. No guarantee

can be given as to the existence of other IPRs not referenced in ETSI SR 000 314 (or the updates on the ETSI Web

Foreword

This Harmonised European Standard (EN) has been produced by ETSI Technical Committee Electromagnetic

compatibility and Radio spectrum Matters (ERM).

The present document has been prepared under the Commission's standardisation request C(2015) 5376 final [i.3] 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.2].

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.

The present document is part 2, sub-part 2 of a multi-part deliverable covering Transport and Traffic Telematics (TTT);

Dedicated Short Range Communication (DSRC) transmission equipment (500 kbit/s / 250 kbit/s) operating in the

5 795 MHz to 5 815 MHz frequency band, as identified below:

Part 1: "General characteristics and test methods for Road Side Units (RSU) and On-Board Units (OBU)";

Part 2: "Harmonised Standard for access to radio spectrum";
Sub-part 1: "Road Side Units (RSU)";
Sub-part 2: "On-Board Units (OBU)".

1 Scope

The present document specifies technical characteristics and methods of measurements for Transport and Traffic

Telematics (TTT) systems:

• with a Radio Frequency (RF) output connection and specified antenna or with an integral antenna;

• for data transmission only;
• operating in the 5 795 MHz to 5 815 MHz frequency band.
The applicability of the present document covers only the On Board Units (OBU).

The present document complies with the Commission Implementing Decision 2017/1483/EU [i.4] and CEPT/ERC

Recommendation 70-03 [i.6].

The present document applies to the following radio equipment types operating in all or in part of the following service

frequency bands given in table 1.
Table 1: Frequency bands and centre frequencies f allocated for DSRC
Pan European Service Frequencies National Service Frequencies
Channel 1 5,795 GHz to 5,800 GHz, f = 5,7975 GHz
Channel 2 5,800 GHz to 5,805 GHz, f = 5,8025 GHz
Channel 3 5,805 GHz to 5,810 GHz, f = 5,8075 GHz
Channel 4 5,810 GHz to 5,815 GHz, f = 5,8125 GHz

NOTE: The relationship between the present document and essential requirements of article 3.2 of

Directive 2014/53/EU [i.2] is given in annex A.
