SIST EN 302 288-2 V1.6.1:2012

• Abstract:

  RSCOM 11-07 decided to amend the existing EC decision 2005/50/EC for the frequency range from 22 GHz to 26,65 GHz with the sunset date 30.6. 2013 to 24,25 GHz to 26,65 GHz with the new sunset date January 1st 2022. This requires an adaption of the current EN 302 288-2.; The present document applies to Short Range Devices (SRDs) in Road Transport and Traffic Telematics (RTTT) systems as described in the scope of EN 302 288-1 [1]:; • with an integral antenna;; • for ultra low power motion and distance monitoring radars for mobile applications only;; • the operating frequency range for intentional UWB emissions has been determined for the range of 22,000 GHz to 26,65 GHz until 30th June 2013 and from 24,25 GHz to 26,65 GHz until 1st January 2018.; However, the date of 1 January 2018 will be extended by 4 years for automotive short-range radar equipment mounted on motor vehicles for which a type approval application has been submitted pursuant to Article 6(6) of Directive 2007/46/EC [i.8] and has been granted before 1st January 2018.; The applicability of the present document covers only the 24 GHz Short Range Radar (SRR) for road vehicles. The present document does not necessarily include all the characteristics which may be required by a user, nor does it necessarily represent the optimum performance achievable.; NOTE: Member States of the European Union are requested to prohibit the taking into service of equipment covered by the present document after a date defined in Commission Decision 2005/50/EC [i.7].; The present document covers transmitters intended to operate in a temporary frequency designation under the EU Commission decision on 24 GHz SRR EC 2005/50/EC [i.7] and the amendment as presented in RSCOM11-21 [i.7].; The present document is intended to cover the provisions of Directive 1999/5/EC (R&TTE Directive) [i.2], article 3.2, which states that "… radio equipment shall be so constructed that it effectively uses the spectrum allocated to terrestrial/space radio communications and orbital resources so as to avoid harmful interference".; The present document responds to the EC mandate M/329 [i.6] for Harmonized Standards covering UltraWide Band (UWB) applications.

SIST EN 302 288-2 V1.6.1:2012 is the Slovenian adoption of ETSI EN 302 288-2 V1.6.1, a harmonized European standard for short range radar equipment operating in the 24 GHz range. It specifies the radio spectrum and electromagnetic compatibility requirements, and the compliance tests, for Road Transport and Traffic Telematics (RTTT) short range devices with integral antennas. It is aimed at manufacturers, test laboratories, and conformity assessment teams that need evidence for article 3.2 of the R&TTE Directive.

What does SIST EN 302 288-2 V1.6.1:2012 specify?

SIST EN 302 288-2 V1.6.1:2012 specifies the harmonized requirements for 24 GHz Short Range Radar (SRR) used in RTTT road-vehicle applications. The standard covers the temporary 24 GHz spectrum arrangement and the related transmitter, receiver, installation, and test provisions needed to show compliance with the essential requirement on efficient spectrum use.

The document applies to Short Range Devices (SRDs) in RTTT systems with an integral antenna and for ultra low power motion and distance monitoring radars for mobile applications only. Its scope is tied to the 24 GHz SRR use case for road vehicles and to the EC decision framework that governs that band.

The document is organized into scope, references, definitions, technical requirements, compliance testing, and two annexes.

Annex	What it covers
Annex A (normative)	HS Requirements and conformance Test specifications Table (HS-RTT), mapping requirements to test specifications and marking them as essential or other
Annex B (informative)	Bibliography

What are the key requirements of SIST EN 302 288-2 V1.6.1:2012?

SIST EN 302 288-2 V1.6.1:2012 is mainly a set of transmitter and receiver limits, plus the tests used to verify them. In practice, it tells a provider what has to be declared, measured, recorded, and included in the test report.

Environmental conditions

Clause 4.1.1 requires the equipment to comply within the declared environmental profile. That means the provider has to state the operating environmental range, and the equipment must meet the radio requirements at representative points within that range.

Transmitter requirements

Clause 4.2.1.1 gives the limits for transmitters in the 22 GHz to 26,65 GHz range for type A and type B. It covers permitted operating frequency ranges, maximum radiated average power density, and maximum radiated peak power density. This is the main control on where the radar may transmit and how strongly it may radiate.

Clause 4.2.1.2 sets the rules for transmitters in the 24,05 GHz to 24,25 GHz band, including the permitted operating range and the peak power limit. Clauses 4.2.1.3 to 4.2.1.5 add limits on vertical plane emissions, emissions in the 24,05 GHz to 26,65 GHz range, and emissions outside the operating-frequency range. These clauses are what keep unwanted radiation under control.

Receiver and installation requirements

Clause 4.2.2.1 limits receiver spurious emissions. Clause 4.2.3 applies the installation requirements from EN 302 288-1, annex G. In practice, the equipment is not assessed only as a box on the bench - the installation arrangement also matters.

Testing and measurement uncertainty

Clause 5 mirrors the technical requirements with test suites. It states which tests to run for transmitters, receivers, and installation-related checks, and it requires tests to be carried out at representative points within the declared environmental profile.

Clause 5.3 requires the measured value to be compared with the corresponding limit, and the test report to include measurement uncertainty for each parameter. The uncertainty is calculated using TR 100 028, with the stated coverage factor, and table 1 sets the maximum uncertainty levels for the listed parameters.

What terms does SIST EN 302 288-2 V1.6.1:2012 define?

• environmental profile - the range of environmental conditions in which the equipment must still comply with the standard.
• Short Range Devices (SRDs) - short-range radio devices covered by the RTTT use case in this standard.
• Road Transport and Traffic Telematics (RTTT) - transport-related telematics applications for road transport systems.
• equivalent isotropically radiated power (e.i.r.p.) - the radiated-power measure used for the transmitter limits and tests.
• R&TTE Directive - the EU directive that sets the essential requirement this standard supports.
• HS-RTT - the annex A requirements-and-tests table that links each requirement to its conformance test.
• UWB - ultra wide band, the application area mentioned in the standard’s mandate context.

Who uses SIST EN 302 288-2 V1.6.1:2012?

SIST EN 302 288-2 V1.6.1:2012 is used by manufacturers of 24 GHz automotive short-range radar equipment, especially for road vehicles. It is also used by test laboratories, compliance engineers, and conformity assessment bodies that have to check transmitter limits, receiver emissions, installation conditions, and measurement uncertainty.

Automotive system integrators and quality teams use it when preparing technical files, planning verification tests, and documenting the evidence needed for presumption of conformity under the R&TTE framework.

Which standards are used with SIST EN 302 288-2 V1.6.1:2012?

• ETSI EN 302 288-1 (V1.6.1) - the companion Part 1 standard that provides the technical requirements and methods of measurement referenced throughout Part 2.
• ETSI TR 100 028 (V1.4.1) - the measurement-uncertainty guidance used in clause 5.3.

What does the SIST EN 302 288-2 V1.6.1:2012 document contain?

The document contains the scope, references, definitions, technical requirements, and compliance testing provisions for 24 GHz RTTT short range radar. Clause 4 sets the limits for transmitter frequency use, radiated power density, vertical-plane emissions, non-operating-band emissions, receiver spurious emissions, and installation requirements.

Clause 5 gives the associated test suites and the rules for environmental test conditions and measurement uncertainty. Annex A provides the cross-reference table used for presumption of conformity, and table 1 gives the uncertainty limits that belong in the test report.
