Overview

SIST EN 301 091-2 V1.2.1:2005 is the harmonised European standard that specifies essential requirements for radar equipment operating in the 76 GHz to 77 GHz frequency range, dedicated to Road Transport and Traffic Telematics (RTTT) applications. This standard falls under the scope of the R&TTE Directive 1999/5/EC, which regulates radio equipment to ensure effective use of the radio spectrum and avoid harmful interference. It complements Part 1 (EN 301 091-1), which addresses technical characteristics and test methods, by focusing on requirements necessary for regulatory compliance and market access within the European Union.

The standard targets short range radar devices integrated in road vehicles, ensuring they are designed and tested to meet electromagnetic compatibility (EMC) and radio spectrum efficiency expectations. It establishes a clear framework for manufacturers and stakeholders seeking conformity assessment under the R&TTE Directive.

Key Topics

• Scope and Applicability

  • Applies to integrated antenna radar equipment for mobile road transport applications operating between 76 GHz and 77 GHz.
  • Focused on essential requirements as defined by Article 3.2 of the R&TTE Directive.

• Technical Requirements

  • Environmental conditions: Radar devices must function within defined operational environmental profiles.
  • Permitted operating frequencies: Devices must operate strictly within the assigned 76 GHz - 77 GHz band.
  • Power specifications: Limits for radiated mean and peak power (e.i.r.p.) to prevent interference.
  • Emission controls: Requirements for out-of-band and spurious emissions for both transmitter and receiver units.

• Conformance and Testing

  • Outlines test suites and procedures to verify compliance with frequency, power, and emissions requirements.
  • Emphasizes the necessity for reliable operation under typical environmental conditions.

• Documentation and Modularity

  • Adopts a modular approach, allowing updates and expansions as technology or regulatory needs evolve.
  • Coordinates with other related standards covering EMC and radio safety.

Applications

SIST EN 301 091-2 V1.2.1:2005 is crucial in the following contexts:

• Automotive Industry

  • Enables the deployment of vehicle-mounted radar systems for advanced driver assistance systems (ADAS), collision avoidance, adaptive cruise control, and other intelligent traffic management applications.
  • Provides assurance of radio spectrum compliance for automotive suppliers entering the EU market.

• Road Transport and Infrastructure

  • Supports integration of traffic telematics solutions in smart infrastructure projects.
  • Facilitates harmonization and interoperability between intelligent transport systems (ITS) across Europe.

• Regulatory Compliance and Market Access

  • Ensures seamless CE marking for manufacturers by demonstrating conformance to article 3.2 of the R&TTE Directive.
  • Reduces complexity and risk in certification processes for radar equipment using the harmonised EN framework.

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.
