Overview

SIST EN 300 674-2-2 V1.1.1:2005 is a harmonized European standard developed to address the electromagnetic compatibility (EMC) and radio spectrum matters (ERM) for Road Transport and Traffic Telematics (RTTT), specifically for Dedicated Short Range Communication (DSRC) transmission equipment. This part focuses on the On-Board Units (OBU), which are devices installed in vehicles to enable efficient communication for RTTT applications such as electronic toll collection and intelligent transport systems. The equipment operates in the 5.8 GHz Industrial, Scientific, and Medical (ISM) band and is designed for data transmission at 500 kbit/s or 250 kbit/s.

This standard fulfills the essential requirements of article 3.2 of the R&TTE Directive (1999/5/EC) by ensuring that radio equipment uses spectrum resources effectively to prevent harmful interference, supporting seamless interoperable transport telematics across Europe.


Key Topics

  • Scope:

    • Applies exclusively to OBUs with RF output connections or integral antennas.
    • Covers operation in the 5.725 GHz to 5.875 GHz ISM band for data transmission.
    • Defines technical and EMC requirements in line with European regulatory frameworks.
  • Technical Requirements:

    • Ensures OBUs operate within declared environmental profiles and power supply conditions.
    • Specifies limits for transmitter power, frequency error, spectrum mask, and unwanted emissions.
    • Mandates receiver spurious emission limits.
  • Testing and Compliance:

    • Outlines standardized test methods for demonstrating compliance.
    • Requires testing under operational environmental boundaries.
  • Conformance:

    • Uses a structured EN Requirements Table (EN-RT) identifying mandatory requirements for transmitters and receivers.

Applications

OBUs compliant with SIST EN 300 674-2-2 V1.1.1:2005 are critical in modern road transport systems, supporting a variety of transport telematics uses, including:

  • Electronic toll collection (ETC):
    Enables seamless, automatic vehicle identification and tolling without stopping at toll gates.

  • Access control and management:
    Grants or denies vehicle access based on authentication via DSRC communication.

  • Traffic management and information systems:
    Facilitates real-time information exchange between vehicles and roadside infrastructure.

  • Commercial vehicle operations:
    Supports fleet management, compliance reporting, and freight tracking over short ranges.

By standardizing radio parameters and EMC requirements, this standard enables interoperability between equipment from different manufacturers while helping avoid interference among devices using the 5.8 GHz band.


Related Standards

OBUs designed under this standard may also need to comply with additional relevant standards, including:

  • EN 300 674-1:
    General characteristics and test methods for both Road Side Units (RSU) and OBUs.

  • EN 301 489:
    EMC requirements across radio equipment and services.

  • Directive 1999/5/EC (R&TTE Directive):
    Broad regulatory framework for radio and telecom terminal equipment in the EU.

  • Council Directive 89/336/EEC (EMC Directive):
    Sets the baseline for electromagnetic compatibility.

  • Council Directive 73/23/EEC (LV Directive):
    Addresses electrical equipment designed for certain voltage limits.

  • ECC/DEC/(02)01 and CEPT/ERC/REC 70-03:
    Coordination and recommendations for SRDs (Short Range Devices) in assigned frequency bands.
