Overview
SIST EN 300 674-2-1 V1.1.1:2005 is a harmonized standard developed by the Slovenski inštitut za standardizacijo (SIST), aligning with EN 300 674-2-1, and produced within the European Telecommunications Standards Institute (ETSI) framework. This document specifies essential requirements for Road Side Units (RSU) used in Road Transport and Traffic Telematics (RTTT) employing Dedicated Short Range Communication (DSRC) at 500 kbit/s or 250 kbit/s, operating within the 5.8 GHz Industrial, Scientific and Medical (ISM) band. It fulfills the provisions set out in article 3.2 of the R&TTE Directive (Directive 1999/5/EC), emphasizing electromagnetic compatibility (EMC) and efficient radio spectrum use.
Key Topics
- Electromagnetic Compatibility (EMC): Ensures RSUs operate without causing or suffering from electromagnetic interference, in accordance with European EMC requirements.
- Radio Spectrum Management: Addresses RF characteristics so RSUs make effective use of the 5.8 GHz ISM band, minimizing harmful interference.
- Conformance Testing: Lays out methods and criteria for testing transmitter and receiver characteristics such as maximum radiated power, frequency accuracy, emission masks, and spurious emissions.
- Environmental Profile: Specifies that RSUs must comply with technical requirements under all declared operating environmental conditions.
- R&TTE Directive Compliance: Establishes that RSUs must satisfy the EU’s essential requirements for efficient spectrum usage and interference avoidance.
Applications
The standard is critical for manufacturers, suppliers, system integrators, and regulatory authorities involved with roadside infrastructure employing DSRC in Intelligent Transport Systems (ITS). Typical applications include:
- Electronic Toll Collection (ETC): RSUs communicate securely with on-board units (OBUs) in vehicles to automate toll payments and manage vehicle classification.
- Traffic Management: Enables real-time vehicle detection, control of traffic flows, and supports traffic data acquisition for roads and highways.
- Access Control: Used at entry/exit points, such as parking areas or restricted zones, allowing automated vehicle identification.
- Urban Mobility Solutions: Supports advanced driver assistance systems and urban transport telematics services.
By ensuring harmonized technical criteria, the standard facilitates cross-border interoperability, contributes to road safety, and supports the broad deployment of ITS applications based on DSRC.
Related Standards
To achieve comprehensive compliance and seamless integration of RSUs, the following related standards and directives are commonly referenced:
- EN 300 674-1: General characteristics and test methods for both Road Side Units (RSU) and On-Board Units (OBU).
- EN 301 489: EMC standard for radio equipment and services.
- ECC DEC (02)01: European decision on frequency designations for RTTT systems.
- CEPT/ERC/REC 70-03: Guidance on short-range device use within the relevant frequency bands.
- EMC Directive (89/336/EEC) and Low Voltage Directive (73/23/EEC): Provide additional safety and compatibility requirements.
- Directive 1999/5/EC (R&TTE Directive): The legal foundation for conformity assessment of radio and telecommunications terminal equipment.
Practical Value
Implementing SIST EN 300 674-2-1 V1.1.1:2005 ensures that RSUs supporting DSRC:
- Are compliant with European regulatory frameworks.
- Achieve optimal performance and reliability in demanding roadside environments.
- Reduce the risk of cross-system and cross-border radio interference.
- Can be readily integrated into broader transport telematics and smart road infrastructures.
This enables safer, more efficient, and future-ready road transport and mobility services across Europe.
