SIST EN 300 674-2-1 V1.1.1:2005 is the Slovenian adoption of ETSI EN 300 674-2-1, a harmonized European standard for Road Side Units (RSU) used in Dedicated Short Range Communication (DSRC) systems. SIST EN 300 674-2-1 V1.1.1:2005 specifies the radio spectrum and electromagnetic compatibility requirements for data-only RSUs operating in the 5,8 GHz Industrial, Scientific and Medical (ISM) band under article 3.2 of the R&TTE Directive. Manufacturers, test laboratories, and conformity assessors use it to check transmitter and receiver performance and to document conformity through the EN Requirements Table (EN-RT).

What does SIST EN 300 674-2-1 V1.1.1:2005 specify?

SIST EN 300 674-2-1 V1.1.1:2005 applies to Road Transport and Traffic Telematics (RTTT) systems with an RF output connection and a specified or integral antenna, for data transmission only, in the 5 725 MHz to 5 875 MHz Industrial, Scientific and Medical (ISM) band. The applicability covers Road Side Units (RSU) only. In practice, this makes the document the reference for fixed roadside DSRC equipment, not for every DSRC device in the series.

The document is organized into:

• Scope, references, definitions, symbols and abbreviations
• Technical requirements specifications
• Testing for compliance with technical requirements
• Annex A, B and C

What are the key requirements of SIST EN 300 674-2-1 V1.1.1:2005?

SIST EN 300 674-2-1 V1.1.1:2005 focuses on a small set of radio-performance limits that matter for spectrum use and interference control. Clause 4 states the limits, and Clause 5 states how to test them.

• Clause 4.1.1 requires the provider to declare an environmental profile, and compliance has to hold within that declared operating range. This matters because the equipment must still meet the standard in the conditions it is actually sold for.
• Clause 4.1.2 requires RSUs to meet all characteristics and essential requirements across the declared power-supply conditions. This is important when the unit sees supply variation in the field.
• Clause 4.2.1.1 limits maximum equivalent isotropically radiated power (e.i.r.p.) by reference to EN 300 674-1. This controls how strongly the RSU can radiate.
• Clause 4.2.1.2 limits frequency error. This matters because a transmitter that drifts too far can interfere with adjacent channels.
• Clause 4.2.1.3 limits the transmitter spectrum mask. This keeps the useful signal inside its intended channel.
• Clause 4.2.1.4 limits unwanted emissions, including spurious and out-of-band emissions. This is the key anti-interference check for nearby services.
• Clause 4.2.2 limits receiver spurious emissions. This matters when the receiver itself can emit unwanted energy.

For testing, Clause 5.1 requires tests at representative points within the declared environmental profile, and enough environmental variation to build confidence in compliance. Clause 5.2 links each requirement to a specific test in EN 300 674-1. Clause 5.3 applies EN 300 674-1 for interpreting results and measurement uncertainty.

What terms does SIST EN 300 674-2-1 V1.1.1:2005 define?

• Environmental profile - the range of environmental conditions under which equipment in scope must comply.
• DSRC - Dedicated Short Range Communication, the short-range radio technique covered by the standard.
• RTTT - Road Transport and Traffic Telematics, the application area for roadside transport communication.
• RSU - Road Side Unit, the equipment type covered by this part.
• e.i.r.p. - equivalent isotropically radiated power, the transmitter power measure used for the emission limit.
• EN-RT - EN Requirements Table, the Annex A table used to summarize requirements for static conformity assessment.

Who uses SIST EN 300 674-2-1 V1.1.1:2005?

SIST EN 300 674-2-1 V1.1.1:2005 is used by RSU manufacturers, RF design teams, test laboratories, conformity assessment bodies, and transport telematics integrators. It is also useful for buyers and quality managers who need to specify or verify RSU radio performance. In practice, they use it for design checks, type testing, test planning, and technical documentation for article 3.2 spectrum compliance.

What changed in SIST EN 300 674-2-1 V1.1.1:2005 from the previous edition?

The document history shows an earlier publication as ES 200 674-2 in February 1999, followed by public enquiry in 2003, a vote in 2004, and publication as EN 300 674-2-1 V1.1.1 in August 2004. The version retained in SIST is the Slovenian adoption of that ETSI publication.

Which standards are used with SIST EN 300 674-2-1 V1.1.1:2005?

• EN 300 674-1 - provides the general characteristics, test methods, definitions, symbols, abbreviations, limit clauses, and the detailed test clauses used throughout this part.
• Directive 1999/5/EC (R&TTE Directive) - gives the legal basis for the harmonized standard under article 3.2.
• ECC/DEC/(02)01 - identifies the frequency bands designated for coordinated introduction of RTTT systems.
• CEPT/ERC/REC 70-03 - covers the use of Short Range Devices and supports the spectrum context for this band.
• Council Directive 89/336/EEC (EMC Directive) and Council Directive 73/23/EEC (LV Directive) - appear in the references as part of the wider regulatory framework.

What does the SIST EN 300 674-2-1 V1.1.1:2005 document contain?

The document contains the scope, references, definitions, technical requirements, and compliance tests for RSU radio equipment. It also includes a frequency-band table for DSRC channels and a modular-structure figure that explains how this part fits into the wider R&TTE standards framework. Annex A provides the EN-RT proforma for static conformity assessment, which is the part used in design reviews, test reports, certification files, and audits. Annex B lists background references, and Annex C gives the title in official languages.

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
