SIST EN 301 357-2 V1.4.1:2009 is the Slovenian adoption of ETSI EN 301 357-2 V1.4.1, a harmonized European standard for cordless audio devices in the 25 MHz to 2 000 MHz range. It specifies minimum performance and measurement methods for equipment covered by Article 3.2 of the R&TTE Directive, so manufacturers and test labs can show that the equipment uses radio spectrum without causing harmful interference. The standard covers cordless headphones, cordless loudspeakers, radio microphones, in-ear monitoring equipment, in-vehicle and personal cordless systems, broadband multichannel audio systems, and Band II LPD.

What does SIST EN 301 357-2 V1.4.1:2009 specify?

SIST EN 301 357-2 V1.4.1:2009 specifies the spectrum-related conformity requirements for cordless audio equipment and how to measure them. Its structure runs from scope and references through definitions, technical requirements, and compliance testing, followed by a normative HS-RTT table in Annex A.

Annex	What it covers
Annex A	HS Requirements and conformance Test specifications Table (HS-RTT)
Annex B	The EN title in the official languages
Annex C	Bibliography

The scope says the equipment is intended to use integral antennas, and that frequency bands may differ from country to country according to national regulations. The term “cordless” is used here only for RF operating systems, not infrared or other non-RF wireless links.

What are the key requirements of SIST EN 301 357-2 V1.4.1:2009?

The standard ties compliance to the declared operational environmental profile. In practice, the supplier has to state the operating conditions, and the equipment has to meet the technical requirements anywhere within those declared limits.

Band II LPD requirements

Clause 4.2.1 sets the transmitter requirements for Band II LPD by pointing to EN 301 357-1. It covers basic requirements, effective radiated power, occupied bandwidth, frequency error, transmitter timeout, and radiated spurious emissions. For Band II LPD, this is the core of the radio check: the device must stay within power, bandwidth, frequency, and unwanted-emission limits.

General cordless audio requirements

Clauses 4.2.2 to 4.2.7 cover frequency error, carrier power, channel bandwidth, spurious emissions and cabinet radiation, cordless audio transmitter shutoff, and receiver spurious emissions and cabinet radiation. These clauses apply to cordless audio devices in the stated range, but not to Band II LPD where the clause says otherwise. For equipment with an integrated receiver, receiver spurious emissions and cabinet radiation also apply to combined equipment such as Band II LPD integrated into a receiver.

Test conditions and uncertainty

Clause 5.1 says tests are carried out at representative points within the declared environmental profile, and at enough different conditions where performance changes with environment. Clause 5.2 says the measured value is used against the limit, and the test report must include measurement uncertainty. The uncertainty figures are based on TR 100 028 and use the stated coverage factors, which matters because test labs need traceable uncertainty data when they judge pass or fail.

Essential radio test suites

Clause 5.3 identifies the essential radio test suites. For Band II LPD, the essential transmitter tests are effective radiated power, occupied bandwidth, frequency error, transmitter timeout, and radiated spurious emissions. For general cordless audio devices, the standard points to the relevant EN 301 357-1 test clauses for frequency error, carrier power, channel bandwidth, spurious emissions, transmitter shutoff, and receiver spurious emissions.

What terms does SIST EN 301 357-2 V1.4.1:2009 define?

• Artificial antenna - A tuned dummy load that reduces radiation and matches the nominal impedance declared by the applicant.
• Integral antenna - An antenna that the manufacturer declares to be an indispensable part of the equipment, with or without a connector.
• Necessary bandwidth - The bandwidth just wide enough to carry the information at the required rate and quality under specified conditions.
• Port - Any connection point on or within the Equipment Under Test (EUT) for cables to or from the equipment.
• Radiated measurements - Measurements of the absolute strength of a radiated electromagnetic field.
• Spurious emission - Emission outside the necessary bandwidth that can be reduced without affecting the intended transmission.
• EUT - Equipment Under Test.
• FDMA - Frequency Division Multiple Access.

Who uses SIST EN 301 357-2 V1.4.1:2009?

Manufacturers and test laboratories use this standard to design, measure, and document cordless audio equipment for R&TTE-related conformity work. It is relevant to cordless audio product lines such as headphones, loudspeakers, consumer radio microphones, in-ear monitoring equipment, in-vehicle systems, personal cordless devices, and broadband multichannel audio systems. It is also used by conformity assessors, quality managers, and technical teams preparing test reports or technical construction files.

What changed in SIST EN 301 357-2 V1.4.1:2009 from the previous edition?

The document history shows earlier published versions V1.1.1, V1.2.1, and V1.3.1 before V1.4.1. The page records V1.4.1 as the published version in November 2008.

Which standards are used with SIST EN 301 357-2 V1.4.1:2009?

• ETSI EN 301 357-1 (V1.4.1) - Supplies the technical characteristics, limit values, and test clauses that this part 2 references for most requirements.
• ETSI TR 100 028 (all parts) (V1.4.1) - Provides the method for calculating measurement uncertainty.
• CEPT/ERC/REC 70-03 - Identifies short range device bands and device categories that are mentioned in the scope.
• ETSI EG 201 399 - Gives the modular structure guide used for harmonized standards under the R&TTE framework.

What does the SIST EN 301 357-2 V1.4.1:2009 document contain?

The document contains the scope, references, definitions, technical requirements, testing rules, and a harmonized standard requirements table. Clause 4 gives the conformance requirements, while Clause 5 explains environmental conditions, measurement uncertainty, and the essential radio test suites. Annex A is the most practical compliance tool because it links each requirement to its test specification and marks whether the requirement is conditional and whether the test is essential. Annex B gives the title in official languages, and Annex C lists bibliography items.

Foreword
This Harmonized European Standard (Telecommunications series) has been produced by ETSI Technical Committee
Electromagnetic compatibility and Radio spectrum Matters (ERM).
The present document has been produced by ETSI in response to a mandate from the European Commission issued
under Council Directive 98/34/EC (as amended) [i.2] laying down a procedure for the provision of information in the
field of technical standards and regulations.
The present document is intended to become a Harmonized Standard, the reference of which will be published in the
Official Journal of the European Communities referencing the Directive 1999/5/EC of the European Parliament and of
the Council of 9 March 1999 on radio equipment and telecommunications terminal equipment and the mutual
recognition of their conformity ("the R&TTE Directive") [i.1].
Technical specifications relevant to Directive 1999/5/EC [i.1] are given in annex A.
The present document is part 2 of a multi-part deliverable covering cordless audio devices in the range 25 MHz to
2 000 MHz, as identified below:
Part 1: "Technical characteristics and test methods";
Part 2: "Harmonized EN covering essential requirements of article 3.2 of the R&TTE Directive".

1 Scope
The present document is intended to specify the minimum performance and the methods of measurement of cordless
audio equipment in the range 25 MHz to 2 000 MHz, including:
• cordless headphones;
• cordless loudspeakers;
• consumer radio microphones in the range 863 MHz to 865 MHz;
• in-ear monitoring equipment using either 300 kHz bandwidth analogue modulation or 300 kHz, 600 kHz,
1 200 kHz digital FDMA modulation in the range 863 MHz to 865 MHz;
• in-vehicle cordless;
• personal cordless;
• broadband multi channel audio systems;
• Band II LPD. (low power devices) in the 87,5 MHz to 108 MHz range (Broadcasting Band II) using up to
200 kHz bandwidth and analogue modulation.
• and other devices and frequency bands defined within CEPT/ERC/REC 70-03 [i.4] or European or National
regulation.
The frequency bands for this equipment may differ from country to country as specified in their national regulations.
All equipment is intended to be used with integral antennas.
The present document is intended to cover the provisions of Directive 1999/5/EC [i.1] (R&TTE Directive), 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".
In addition to the present document, other ENs that specify technical requirements in respect of essential requirements
under other parts of Article 3 of the R&TTE Directive may apply to equipment within the scope of the present
document.
NOTE 1: A list of such ENs is included on the web site http://www.newapproach.org.
NOTE 2: The term cordless is also used to describe infra red and other non-RF "wireless" links, but in the context
of the present document it is restricted to RF operating systems only.
2 References
