SIST EN 302 288-2 V1.1.1:2005 is the Slovenian adoption of ETSI EN 302 288-2 V1.1.1. It is a harmonized European standard for 24 GHz short range radar equipment used in Road Transport and Traffic Telematics (RTTT), and it supports the essential requirements of article 3.2 of the R&TTE Directive. In practice, it tells manufacturers and test labs how to show that this radio equipment uses spectrum within the agreed limits.
What does SIST EN 302 288-2 V1.1.1:2005 specify?
SIST EN 302 288-2 V1.1.1:2005 specifies spectrum-related and electromagnetic compatibility requirements for RTTT short range radar equipment with an integral antenna, intended for ultra low power motion and distance monitoring in mobile applications. The focus is the 24 GHz Short Range Radar (SRR) for road vehicles, operating in the 22 GHz to 26,625 GHz range.
The document is organized into scope, references, definitions, technical requirements, compliance testing, and three annexes. Annex A is normative and gives the EN Requirements Table (EN-RT); Annex B lists the EN title in official languages; Annex C gives the bibliography.

What are the key requirements of SIST EN 302 288-2 V1.1.1:2005?
SIST EN 302 288-2 V1.1.1:2005 sets the transmitter, receiver, installation, and test rules that a 24 GHz SRR device must meet to claim conformity. The key point is that the standard uses limits and methods from EN 302 288-1, so this part defines the harmonized requirements while Part 1 carries the detailed technical values and measurements.
Operating conditions and environmental profile
The equipment shall comply within the declared operational environmental profile and all declared power supply conditions. This matters because compliance is tied to the real operating range the provider declares, not to a single ideal lab condition.
Transmitter limits
The transmitter operating frequency range, maximum radiated average power density, and maximum radiated peak power density shall stay within the limits referenced from EN 302 288-1. For transmitters in the 24,050 GHz to 24,250 GHz band, the document also points to specific frequency-range and e.i.r.p. limits.
Emissions control
The transmitter shall meet vertical plane emission limits in the 23,6 GHz to 24,0 GHz range, and its spurious and out-of-band emissions shall remain within the referenced limits. The receiver shall also meet spurious emission limits. In practice, these clauses control unwanted radiation that could interfere with other radio systems.
Installation requirements
Installation requirements from annex D of EN 302 288-1 apply. This means conformity is not only about the radio module itself, but also about how it is fitted into the vehicle or host equipment.
Testing and measurement
Tests are to be carried out at representative points within the declared environmental profile, and with enough environmental variety where performance changes with conditions. Interpretation of results and measurement uncertainty follow clause 4.4 of EN 302 288-1.
Conformity summary
Annex A identifies the main EN requirements as mandatory and groups them into transmitter, receiver, and installation entries. This is useful for static conformity assessment and for checking that all required topics have been covered.
What terms does SIST EN 302 288-2 V1.1.1:2005 define?
- Environmental profile - The range of environmental conditions in which the equipment is required to comply.
- Equivalent isotropically radiated power (e.i.r.p.) - A way to express radiated transmitter power in a standard reference form for comparing emissions.
- Short Range Devices (SRD) - Short-range radio devices covered by this family of standards.
- Road Transport and Traffic Telematics (RTTT) - Radio and data systems used for road transport and traffic applications.
- EN Requirements Table (EN-RT) - The summary table in Annex A that lists each requirement and its status.
- Spurious emissions - Unwanted emissions outside the intended signal, relevant to both transmitter and receiver compliance.
- Out-of-band emissions - Unwanted transmitter emissions close to, but outside, the assigned operating band.
Who uses SIST EN 302 288-2 V1.1.1:2005?
Manufacturers of 24 GHz road vehicle radar equipment use this standard to design products for the harmonized band and to prepare compliance evidence. Test laboratories use it to run the required transmitter and receiver tests, usually by following the measurement methods referenced from EN 302 288-1.
Quality managers, compliance teams, and conformity assessment bodies use Annex A and the clause references to check that all required items are covered. Regulators and buyers in vehicle electronics use it to understand what kind of radio performance and emissions control the equipment is supposed to meet.
Which standards are used with SIST EN 302 288-2 V1.1.1:2005?
- ETSI EN 302 288-1 - Provides the technical requirements and methods of measurement that this part references for limits, tests, uncertainty, and installation requirements.
- ETSI EN 301 489 (all parts) - The EMC standard for radio equipment and services, mentioned in the modular R&TTE structure.
- ETSI EN 302 264 - Covers UWB radar equipment operating above 60 GHz and is cited in the bibliography as a related radar standard.
What does the SIST EN 302 288-2 V1.1.1:2005 document contain?
The document contains the harmonized spectrum-use requirements for 24 GHz RTTT short range radar, with clause-by-clause limits for transmitters and receivers. It also contains the test clauses that point to the corresponding methods in EN 302 288-1, so users can connect each requirement to a compliance test.
Annex A provides a compact requirement table that is useful for audits and conformity checklists. Annex B gives the title in several official languages, and Annex C lists background references such as the R&TTE-related material and the related 79 GHz radar standard.

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.
The vertical boxes show the standards under article 3.2 for the use of the radio spectrum by radio equipment. The
scopes of these standards are specified either by frequency (normally in the case where frequency bands are
harmonized) or by radio equipment type.
For article 3.1b the diagram shows EN 301 489 [7], the multi-part product EMC standard for radio used under the
EMC Directive [2].
For article 3.1a the diagram shows the existing safety standards currently used under the LV Directive [3] and new
standards covering human exposure to electromagnetic fields. New standards covering acoustic safety may also be
required.
The bottom of the figure shows the relationship of the standards to radio equipment and telecommunications terminal
equipment. A particular equipment may be radio equipment, telecommunications terminal equipment or both. A radio
spectrum standard will apply if it is radio equipment. An article 3.3 standard will apply as well only if the relevant
essential requirement under the R&TTE Directive [1] is adopted by the Commission and if the equipment in question is
covered by the scope of the corresponding standard. Thus, depending on the nature of the equipment, the essential
requirements under the R&TTE Directive [1] may be covered in a set of standards.
The modularity principle has been taken because:
• it minimizes the number of standards needed. Because equipment may, in fact, have multiple interfaces and
functions it is not practicable to produce a single standard for each possible combination of functions that may
occur in an equipment;
• it provides scope for standards to be added:
