SIST EN 300 674-2-2 V1.1.1:2005 is the Slovenian adoption of ETSI EN 300 674-2-2 V1.1.1, published by SIST. It is a harmonized European standard for Dedicated Short Range Communication (DSRC) transmission equipment in the 5,8 GHz Industrial, Scientific and Medical (ISM) band, and it sets the radio-spectrum requirements for On-Board Units (OBU) used in Road Transport and Traffic Telematics (RTTT).

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

SIST EN 300 674-2-2 V1.1.1:2005 specifies the technical requirements and test methods that OBUs must meet to support the essential requirements of article 3.2 of the R&TTE Directive. It applies to data-only RTTT equipment with an RF output connection and a specified antenna or an integral antenna, operating in the 5,725 GHz to 5,875 GHz ISM band.

The document is organized into five clauses and three annexes:

Annex	What it covers
A	The EN Requirements Table (EN-RT) for OBUs
B	Bibliography
C	The EN title in the official languages

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

SIST EN 300 674-2-2 V1.1.1:2005 focuses on a small set of radio-performance limits and the test approach needed to prove them. In practice, the document tells suppliers and test labs what to declare, what to measure, and which clauses in EN 300 674-1 supply the detailed limits and methods.

Environmental and supply conditions

Clause 4.1 requires the equipment to meet the standard across the declared environmental profile and across the declared power-supply conditions. That means the provider must define the operating environment and supply range before claiming conformity.

Transmitter limits

Clause 4.2.1 covers four transmitter requirements:

• maximum equivalent isotropically radiated power (e.i.r.p.)
• frequency error
• transmitter spectrum mask
• unwanted emissions

Each of these points to a limit in EN 300 674-1, and each matters because it keeps the OBU within its intended channel and reduces interference to other users of the band.

Receiver emissions

Clause 4.2.2 limits receiver spurious emissions. This matters in practice because even receive-only behaviour can create unwanted radio energy that affects nearby equipment.

Test conditions

Clause 5.1 says testing must be done at representative points within the declared environmental profile, and over enough environmental variation to give confidence in compliance. For a buyer or lab, that means test evidence must match the actual operating conditions of the product.

Essential radio test suites

Clause 5.2 links each requirement to a named test in EN 300 674-1:

• 10.4 for maximum e.i.r.p.
• 10.5 for frequency error
• 10.6 for transmitter spectrum mask
• 10.7 for unwanted emissions
• 10.8 for receiver spurious emissions

Clause 5.3 then says to apply the interpretation of results and measurement uncertainty rules in EN 300 674-1. This is the part that controls how borderline results are judged.

Static conformity summary

Annex A turns the requirements into an EN-RT summary table for OBUs. That table is useful for conformity assessment because it shows which entries are mandatory and how each requirement maps to the clauses.

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

• Road Transport and Traffic Telematics (RTTT) - The transport telematics application area covered by the standard.
• Dedicated Short Range Communication (DSRC) - The short-range radio communication system used by the equipment in scope.
• On-Board Unit (OBU) - The vehicle-mounted unit covered by this sub-part.
• equivalent isotropically radiated power (e.i.r.p.) - A transmitter power measure used for the output-power limit.
• environmental profile - The declared range of environmental conditions under which compliance must hold.
• EN Requirements Table (EN-RT) - The annex table that summarizes the requirements for conformity assessment.

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

SIST EN 300 674-2-2 V1.1.1:2005 is used by OBU designers, radio manufacturers, conformity assessment bodies, and test laboratories. It is also relevant to buyers and quality managers who need to check that vehicle-mounted DSRC equipment has been specified and tested for the correct spectrum, emissions, and measurement conditions.

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

The history lists an earlier publication as ES 200 674-2 and shows the later enquiry, vote, and publication steps that led to the August 2004 edition. The document itself presents the 2004-08 version as ETSI EN 300 674-2-2 V1.1.1.

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

• ETSI EN 300 674-1 - provides the general characteristics, detailed limits, test methods, and measurement uncertainty rules that this sub-part references.
• Directive 1999/5/EC (R&TTE Directive) - provides the article 3.2 legal basis for the harmonized standard.
• ECC/DEC/(02)01 - identifies the frequency bands for coordinated introduction of RTTT systems.
• CEPT/ERC/REC 70-03 - gives the short-range device spectrum-use framework cited by the scope.
• Council Directive 89/336/EEC and Council Directive 73/23/EEC - appear in the reference set and the modular-structure discussion as part of the wider regulatory context.

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

The document contains a short regulatory foreword, a scope statement, references, definitions, technical requirements, and compliance test clauses. It also includes a modular-structure figure showing where spectrum, EMC, safety, and other article 3 requirements sit in the R&TTE system.

Annex A provides the EN-RT proforma for OBUs, which can be completed for conformity assessment. Annex B lists background references, and Annex C gives the title in official languages.

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.
