kSIST prES 200 674-1 V2.3.1:2012 is a SIST standard based on ETSI ES 200 674-1 V2.3.1. It specifies the technical characteristics and test methods for High Data Rate (HDR) Dedicated Short Range Communications (DSRC) equipment used in Intelligent Transport Systems (ITS) and Road Transport and Traffic Telematics (RTTT) in the 5,8 GHz Industrial, Scientific and Medical (ISM) band. The document is written for Road Side Units (RSUs) and On Board Units (OBUs), including transceivers and transponders, and it tells users how to verify the radio, data link and application-layer limits.

What does kSIST prES 200 674-1 V2.3.1:2012 specify?

kSIST prES 200 674-1 V2.3.1:2012 specifies radio parameters, data link services, protocol data units, and application services needed for efficient use of the spectrum for DSRC-based applications. It also gives the measurement methods used to verify the limits.

The scope is limited to 5,8 GHz Short Range Devices for RTTT that have either an RF output connection with a specified antenna or an integral antenna, are used for data transmission only, and operate in the 5 725 MHz to 5 875 MHz ISM band. The applicability covers both RSUs and OBUs, including transceivers and transponders.

The document is organized into:

• Clauses 1 to 3 for scope, references, definitions, symbols and abbreviations
• Clause 4 for presentation of equipment for testing, design and marking
• Clauses 5 and 6 for test conditions and general arrangements
• Clauses 7 to 9 for Layer 1 radio measurements on RSUs and OBUs
• Clause 10 for Layer 2 parameters and procedures
• Clause 11 for Layer 7 parameters and procedures
• Clause 12 for measurement uncertainty

Annex	What it covers
Annex A	Radiated measurement sites and arrangements
Annex B	General description of measurement methods
Annex C	Receiver measurement methods using messages
Annex D	EETS profile for the European Electronic Fee Collection service

What are the key requirements of kSIST prES 200 674-1 V2.3.1:2012?

kSIST prES 200 674-1 V2.3.1:2012 is mainly a type-testing and conformance document. The practical job of the standard is to define what has to be tested, how to test it, and what kind of test evidence belongs in the report.

Equipment presentation and test preparation

Clause 4 requires the applicant to submit equipment that is representative of the production model and to provide the application form, technical documentation and operating manuals. If the equipment needs ancillary items for testing, those items must accompany it.

In practice, this means the lab should not be left to guess the normal configuration. The equipment has to be tested on all frequencies over which it is intended to operate, and the declared power levels and antenna gains have to be stated in the application form and the test report.

Test conditions, power sources and temperatures

Clauses 5 and 6 define the normal and extreme test conditions, including the external test power source, temperature, humidity and voltage conditions. The document also requires an unmodulated carrier facility for transmitter measurements, and it allows special test signals where needed.

This matters because results must be repeatable at the lab and meaningful for field use. For example, receiver measurements can use an encoder and either continuous bit streams or correctly coded messages, and the test report has to describe the signal format that was used.

Clause 6 also sets up the measurement interfaces:

• A 50 Ω artificial antenna with VSWR not greater than 1,2:1
• A calibrated test fixture for integral-antenna equipment, with documented characteristics and coupling loss
• Specific arrangements for radiated measurements, with guidance in Annex A

RSU Layer 1 transmitter and receiver tests

Clauses 7 and 8 cover the RSU physical layer. Transmitter tests include equivalent isotropically radiated power (e.i.r.p.), frequency error, transmitter spectrum mask, modulation depth, eye pattern and spurious emissions. Receiver tests include maximum useable sensitivity, error behaviour at high wanted input signals, co-channel rejection, adjacent channel selectivity, spurious response rejection, blocking/desensitization, intermodulation response rejection, and receiver spurious emissions.

These are the core radio checks that show whether an RSU can radiate within limits and still receive correctly in the presence of wanted and unwanted signals. Clause 8 prefers continuous bit streams for receiver testing, with a nominal Bit Error Ratio (BER) of 1 × 10^-6, while message-based testing is allowed in special cases and is described in Annex C.

OBU Layer 1 tests

Clause 9 sets the OBU physical layer measurements. The main items are OBU sensitivity, on-board unit access, transponder conversion gain, maximum radiated subcarrier, frequency error and spurious radiation.

This matters because OBUs are tested differently from RSUs: the standard separates transceivers from transponders, and clause 9.3 applies only to transponders. The test setups use radiated arrangements, orientation angles and field strengths that reflect how the OBU is used in the communication zone.

Layer 2 and Layer 7 behaviour

Clause 10 defines the Layer 2 frame structure and the rules for opening and closing flags, LPDU validity, frame check sequence, transmission, reception and Link ID allocation. It also gives RSU-specific and OBU-specific procedures for frame transmission and reception.

Clause 11 defines the Layer 7 protocol. The protocol is asymmetric: the RSU is always the master and issues directives, while the OBU is always the slave and sends responses. The clause also defines the ASN.1 message structures, encoding rules, session rules, and a long list of directives such as Open-Rq, Close-Rq, Select-TBA-Id-Rq, Read-Display-Type-Rq, Write-Appl-Core-Rq, Set-Password-Rq and Get-Credential-Rq.

For users, this is the interoperability part of the standard. It tells implementers which APDUs are valid, when a request needs an active session, how long responses may be after encoding, and how RSU and OBU procedures have to line up.

EETS profile and measurement uncertainty

Annex D narrows the protocol choices for the European Electronic Fee Collection service (EETS). It specifies which directives, data, memory structure and security algorithms are used for that service.

Clause 12 gives the measurement uncertainty targets for the test system. In practice, a lab has to check that its own uncertainty stays within the stated bounds, or the measurements may not be acceptable against the standard.

What terms does kSIST prES 200 674-1 V2.3.1:2012 define?

• Dedicated Short Range Communications (DSRC) - The short-range communication system covered by the standard for RTTT and ITS applications.
• Road Side Unit (RSU) - The roadside equipment that communicates with OBUs and acts as the master role at Layer 7.
• On Board Unit (OBU) - The vehicle-side or on-board equipment that communicates with the RSU and acts as the slave role at Layer 7.
• Transceiver OBU - An OBU with local receiver and transmitter 5,8 GHz frequency generation.
• Transponder - An OBU without its own 5,8 GHz frequency generation.
• Equivalent isotropically radiated power (e.i.r.p.) - Radiated power referenced to an isotropic antenna, used to characterize transmitter output.
• Bit Error Ratio (BER) - The error metric used in receiver performance tests and sensitivity measurements.
• Application Protocol Data Unit (APDU) - The Layer 7 protocol message structure used for directives and responses.

Who uses kSIST prES 200 674-1 V2.3.1:2012?

kSIST prES 200 674-1 V2.3.1:2012 is used by manufacturers, test laboratories, and organizations that evaluate DSRC-HDR equipment for road transport systems. It is also useful for quality managers, compliance teams and buyers who need to check whether RSUs or OBUs match the required radio and protocol behavior.

In practice, users apply it when they:

• prepare equipment for type testing
• set up conducted or radiated measurements
• verify transmitter and receiver performance
• check Layer 2 frame handling and Layer 7 protocol messages
• configure EETS-related behavior for electronic fee collection equipment
