Overview

SIST EN 301 091-2 V1.2.2:2006 is a harmonized Slovene and European Standard addressing the essential requirements for electromagnetic compatibility (EMC) and radio spectrum use in short range devices, specifically radar equipment used in road transport and traffic telematics (RTTT) applications within the 76 GHz to 77 GHz frequency range. The standard covers equipment with integral antennas intended for mobile use in vehicles, and aligns with Article 3.2 of the R&TTE Directive (1999/5/EC), which mandates that radio equipment must effectively utilize allocated spectrum while avoiding harmful interference.

This standard applies to radar systems for road vehicles as designated within the coordinated European frequency allocation frameworks established by CEPT/ECC/DEC(02)01 and CEPT/ERC/REC 70-03. It aims to ensure conformity while supporting the safe and efficient integration of radar-based technologies in intelligent transport systems.

Key Topics

• Electromagnetic compatibility (EMC): Establishes requirements to minimize unintentional electromagnetic emissions and ensure immunity to external interference for RTTT radar equipment.
• Radio spectrum matters: Addresses the efficient and interference-free use of the 76 GHz to 77 GHz band by short range radar devices in road vehicles.
• Transmitter requirements: Specifies mandatory limits on operating frequency, radiated mean and peak power (e.i.r.p.), and permissible levels for out-of-band and spurious emissions.
• Receiver requirements: Defines standards for limiting spurious emissions where applicable.
• Testing and compliance: Outlines standardized test suites and environmental conditions to verify conformity to technical and operational specifications under realistic usage scenarios.
• Conformance documentation: Introduces the EN Requirements Table (EN-RT), enabling stakeholders to clearly document and assess compliance for radar equipment.

Applications

SIST EN 301 091-2 V1.2.2:2006 is vital for:

• Road vehicle radar systems: Ensures reliable electromagnetic performance for mobile radars used in automotive safety features, such as adaptive cruise control, collision avoidance, blind spot detection, and traffic monitoring systems.
• Manufacturers and integrators: Enables radar technology providers to develop and test compliant devices, ensuring alignment with European regulations for EMC and spectrum usage.
• Type approval and certification: Supports the certification process for placing road vehicle radar equipment on the European market, demonstrating conformity with harmonized standards under the R&TTE Directive.
• National authorities and regulators: Provides a reference for market surveillance and regulatory enforcement related to radio equipment in the 76 GHz to 77 GHz band.

Related Standards

• EN 301 091-1: Defines the technical characteristics and testing methods for radar equipment operating in the 76 GHz to 77 GHz frequency range.
• EN 301 489 (all parts): Covers EMC requirements for all radio equipment and services, including short range devices and road traffic telematics systems.
• CEPT/ECC/DEC(02)01: Specifies the coordinated European frequency bands for RTTT systems.
• CEPT/ERC/REC 70-03: Relates to the broader regulatory framework for the use of short range devices (SRDs) across Europe.
• Directive 1999/5/EC (R&TTE Directive): Provides the legislative context for placing radio and telecommunications terminal equipment on the EU market.
• EMC Directive (89/336/EEC) and LV Directive (73/23/EEC): Contains additional requirements relevant to electrical and EMC safety for related device categories.

By adhering to SIST EN 301 091-2 V1.2.2:2006, manufacturers and stakeholders ensure their RTTT radar equipment is market-ready, legal, and reliable, contributing to safer and smarter road transport infrastructures throughout Europe.

Foreword
This Candidate 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 [1] 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").
Technical specifications relevant to Directive 1999/5/EC [1] are given in annex A.
The present document is part 2 of a multi-part deliverable covering Electromagnetic compatibility and Radio spectrum
Matters (ERM); Short Range Devices; Road Transport and Traffic Telematics (RTTT); Radar equipment operating in
the 76 GHz to 77 GHz range, as identified below:
Part 1: "Technical characteristics and test methods for radar equipment operating in the 76 GHz to 77 GHz
range";
Part 2: "Harmonized EN covering essential requirements of article 3.2 of the R&TTE Directive".

Introduction
The present document is part of a set of standards designed to fit in a modular structure to cover all radio and
telecommunications terminal equipment under the R&TTE Directive [1]. Each standard is a module in the structure.
The modular structure is shown in figure 1.

The left hand edge of the figure 1 shows the different clauses of article 3 of the R&TTE Directive [1].
For article 3.3 various horizontal boxes are shown. Dotted lines indicate that at the time of publication of the present
document essential requirements in these areas have to be adopted by the Commission. If such essential requirements
are adopted, and as far and as long as they are applicable, they will justify individual standards whose scope is likely to
be specified by function or interface type.
The vertical boxes show the standards under article 3.2 for the use of the radio spectrum by radio equipment. The
scopes of these standards are specified either by frequency (normally in the case where frequency bands are
harmonized) or by radio equipment type.
For article 3.1b the diagram shows EN 301 489 [6], the multi-part product EMC standard for radio used under the
EMC Directive [2].
For article 3.1a the diagram shows the existing safety standards currently used under the LV Directive [3] and new
standards covering human exposure to electromagnetic fields. New standards covering acoustic safety may also be
required.
The bottom of the figure shows the relationship of the standards to radio equipment and telecommunications terminal
equipment. A particular equipment may be radio equipment, telecommunications terminal equipment or both. A radio
spectrum standard will apply if it is radio equipment. An article 3.3 standard will apply as well only if the relevant
essential requirement under the R&TTE Directive [1] is adopted by the Commission and if the equipment in question is
covered by the scope of the corresponding standard. Thus, depending on the nature of the equipment, the essential
requirements under the R&TTE Directive [1] may be covered in a set of standards.
The modularity principle has been taken because:
• it minimizes the number of standards needed. Because equipment may, in fact, have multiple interfaces and
functions it is not practicable to produce a single standard for each possible combination of functions that may
occur in an equipment;
• it provides scope for standards to be added:
- under article 3.2 when new frequency bands are agreed; or
- under article 3.3 should the Commission take the necessary decisions without requiring alteration of
standards that are already published;
• it clarifies, simplifies and promotes the usage of Harmonized Standards as the relevant means of conformity
assessment.
