kSIST prES 200 674-1 V2.4.1:2013 is a SIST publication of the ETSI standard for Intelligent Transport Systems (ITS) and Road Transport and Traffic Telematics (RTTT) Dedicated Short Range Communications (DSRC). It specifies the technical characteristics and test methods for High Data Rate (HDR) data transmission equipment operating in the 5,8 GHz Industrial, Scientific and Medical (ISM) band. It is aimed at manufacturers, test laboratories, and type-testing applicants who need to verify RSUs, OBUs, and related DSRC functions.

What does kSIST prES 200 674-1 V2.4.1:2013 specify?

kSIST prES 200 674-1 V2.4.1:2013 specifies radio parameters, data link services and protocol data units, and application services and protocol data units needed for DSRC-based applications. It also gives the measurement methods used to check those limits in practice.

The standard applies to 5,8 GHz Short Range Devices (SRDs) for RTTT use:

• with an RF output connection and specified antenna, or with an integral antenna
• for data transmission only
• operating in the 5 725 MHz to 5 875 MHz ISM band

The document covers both Road Side Units (RSUs) and On Board Units (OBUs). Clause 1 states the scope, Clauses 2 and 3 give references and definitions, Clauses 4 to 6 cover presentation for testing and test conditions, Clauses 7 to 9 cover Layer 1 transmitter and receiver methods, Clause 10 covers Layer 2, Clause 11 covers Layer 7, and Clause 12 covers measurement uncertainty. The normative annexes add radiated methods, general measurement guidance, message-based receiver methods, and the European Electronic Fee Collection service profile.

Annex	What it covers
Annex A	Radiated measurement sites and arrangements, including anechoic chamber, chamber with conductive ground plane, and Open Area Test Site (OATS)
Annex B	General conducted and radiated measurement methods
Annex C	Alternative receiver measurement methods using messages instead of bit streams
Annex D	Profile for the European Electronic Fee Collection service, including EETS data, directives, memory structure, and security requirements

What are the key requirements of kSIST prES 200 674-1 V2.4.1:2013?

kSIST prES 200 674-1 V2.4.1:2013 is built around type testing: the equipment has to be presented in a representative form, tested under controlled conditions, and measured with documented uncertainty. In practice, the standard is as much about how to test as about what to test.

Testing setup and test conditions

Clause 4 requires the equipment submitted for type testing to represent the production model and to be accompanied by the applicant’s form, technical documentation, operating manuals, and any auxiliary test equipment. This matters because the laboratory needs enough information to test the product in the same way it will be used.

Clause 5 sets the normal and extreme test conditions, including external test power sources, temperature, humidity, and supply voltage. For battery-operated equipment, the battery is removed and replaced by an external source arranged to avoid affecting radiated measurements. That keeps the results repeatable and comparable across laboratories.

Clause 6 defines the test signals, modulation, receiver encoder arrangements, artificial antenna conditions, and test fixture requirements. The standard requires a 50 Ω artificial antenna where applicable, and the test fixture for integral-antenna equipment has to be calibrated and documented by the manufacturer. Clause 6 also includes specific RSU and OBU test conditions, including the wake-up trigger for OBU operation.

Clause 12 requires the measurement system uncertainty to stay within the stated limits and to be reported. The uncertainty figures are tied to a 95 % confidence level. For a buyer or quality manager, this means the test report is not complete unless it shows both the measured value and the uncertainty.

RSU Layer 1 transmitter requirements

Clause 7 covers RSU transmitter parameters such as Equivalent Isotropically Radiated Power (e.i.r.p.), frequency error, transmitter spectrum mask, modulation depth, eye pattern, and spurious emissions. The measurements are made under normal and extreme conditions, and the e.i.r.p. measurement is performed in unmodulated mode.

The spectrum mask is important because it relates directly to reuse distance between RSUs. In practice, this tells system designers and operators how much unwanted energy is allowed outside the wanted channel, which affects interference between nearby installations. Clause 7 also requires conducted, cabinet, and radiated spurious emissions to be checked.

RSU Layer 1 receiver requirements

Clause 8 covers RSU receiver sensitivity, error behaviour at high wanted input signals, and degradation tests such as co-channel rejection, adjacent channel selectivity, spurious response rejection, blocking/desensitization, and intermodulation response rejection. These are the tests that show whether the RSU can keep working in a noisy or crowded radio environment.

The preferred method uses continuous bit streams. The nominal Bit Error Ratio (BER) is 1 × 10-6, with a practical test range of 0,5 × 10-6 to 2 × 10-6. Where message-based testing is used instead, the success criterion is 80 % over 20 message trials, and Annex C describes that method. For the reader, this means the receiver tests are not just pass-fail checks, but controlled sensitivity and interference measurements.

OBU Layer 1 requirements

Clause 9 covers OBU sensitivity, access behavior, transponder conversion gain, maximum radiated subcarrier, frequency error, and spurious radiation. Some OBU tests use specific antenna angles and polarization conditions, so the test setup is part of the requirement, not just the result.

The clause distinguishes between transponders and transceivers. Transponders are covered by conversion gain measurements, while transceivers are measured for maximum output power according to the OBU-specific methods. This matters when selecting or qualifying vehicle equipment because the radio architecture changes what must be verified.

Layer 2 and Layer 7 interoperability

Clause 10 defines the Layer 2 frame structure, opening and closing flags, LPDU content, frame check sequence, and the frame transmission and reception procedures. It also gives specific Road Side Unit and On Board Unit parameters such as Link ID allocation. In practice, this is the frame-level interoperability layer, so it governs whether RSU and OBU data are exchanged correctly.

Clause 11 defines the Layer 7 protocol. The protocol is asymmetric: the RSU always acts as the master and issues directives, while the OBU always acts as the slave and sends responses. The clause includes ASN.1 definitions, encoding rules, sessions, and many request and response messages for reading, writing, password handling, credentials, and application data. For implementers, this is the part that controls application behavior beyond the radio link.

EETS profile and security

Annex D profiles the document for the European Electronic Fee Collection service (EETS). It limits the directives and responses used for EETS applications, specifies how the OBU memory structure is organized, and defines the security algorithms and requirements. That makes the annex particularly relevant for tolling applications where interoperability and security both matter.

What terms does kSIST prES 200 674-1 V2.4.1:2013 define?

• Road Side Unit (RSU) - the roadside equipment that communicates with OBUs and acts as the master at Layer 7.
• On Board Unit (OBU) - the vehicle-side unit that communicates with the RSU and acts as the slave at Layer 7.
• Equivalent Isotropically Radiated Power (e.i.r.p.) - the radiated power level used to describe transmitter output as seen from an isotropic antenna.
• Application Protocol Data Unit (APDU) - the Layer 7 application message exchanged between RSU and OBU.
• Link Layer Protocol Data Unit (LPDU) - the Layer 2 data unit carried inside a frame.
• Bit Error Ratio (BER) - the ratio used to judge receiver performance in continuous bit-stream testing.
• European Electronic Tolling Service (EETS) - the tolling service profile covered in Annex D.

Who uses kSIST prES 200 674-1 V2.4.1:2013?

Manufacturers use kSIST prES 200 674-1 V2.4.1:2013 to design RSUs, OBUs, transceivers, and transponders that match the stated radio and protocol behavior. Test laboratories use it to set up conducted and radiated measurements, choose test signals, and record uncertainty.

Type-testing applicants and quality managers use it to prepare the sample, supply the right documentation, and check whether the equipment meets the declared limits. Tolling and EETS integrators use it when they need Layer 7 compatibility, directive handling, memory structure, and security behavior that fit the service profile.

What changed in kSIST prES 200 674-1 V2.4.1:2013 from the previous edition?

kSIST prES 200 674-1 V2.4.1:2013 replaces V2.3.1 and states that it corrects minor editorial and technical inconsistencies found after the STF 422 test specifications. The document history shows the earlier V2.3.1 edition and the later V2.4.1 publication.

What does the kSIST prES 200 674-1 V2.4.1:2013 document contain?

The document contains detailed transmitter, receiver, Layer 2, and Layer 7 test methods, with limits and conditions attached to each one. It includes figures for test arrangements such as wake-up triggering, receiver sensitivity setups, and radiated measurement sites, plus tables for limits, message parameters, and EETS-specific values.

Annex A describes anechoic chambers, chambers with ground planes, and OATS setups for radiated testing. Annex B explains the general conducted and radiated measurement methods, including substitution-style approaches and how to determine radiated performance.

Annex C adapts receiver tests to message-based operation, which is useful when bit-stream testing is not practical. Annex D provides the EETS profile, including allowed data, directives, memory organization, and security computations.

Clause 12 and the annexes also support laboratory reporting, because they tie together the test setup, the measurement method, and the uncertainty that must be recorded.
