It is the intention of the present document to cover any Channel Bandwidths (CBW) permitted by National Administrations for such systems e.g. 6,25 kHz. In the present document different requirements are given for the different radio frequency bands, environmental conditions and types of equipment where appropriate. In the present document, data transmission systems are defined as systems which transmit and/or receive data and/or digitized voice. The equipment comprises a transmitter and associated encoder and modulator and/or a receiver and associated demodulator and decoder. The present document covers equipment which may use constant envelope or non-constant envelope modulation.
The types of equipment covered by the present document are as follows:
- base station: equipment fitted with antenna connector;
- mobile station: equipment fitted with antenna connector.
- handportable stations:
a) either fitted with an antenna connector; or
b) without an external antenna connector but fitted with a permanent internal or a temporary internal 50 Ω RF connector which allows access to the transmitter output and the receiver input. Handportable station equipment without an external or internal Radio Frequency (RF) connector and without the possibility of having a temporary internal 50 Ω RF connector is not covered by the present document. The present document is intended to cover the provisions of article 3.2 of Directive 1999/5/EC [1] (R&TTE Directive), 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".

Overview

SIST EN 301 166-2 V1.2.1:2007, developed by the Slovenski inštitut za standardizacijo (SIST), specifies Harmonized European requirements for electromagnetic compatibility (EMC) and efficient radio spectrum usage for land mobile radio equipment. This standard is crucial for Private Mobile Radio (PMR) systems, addressing both analogue and digital radio equipment designed for speech and/or data communication over narrow-band channels (with channel spacing less than 10 kHz). It ensures compliance with Article 3.2 of the R&TTE Directive (1999/5/EC), which requires radio equipment to use the radio spectrum efficiently and avoid causing harmful interference.

Key Topics

  • Scope of Application: The standard applies to radio transmitters and receivers used at fixed, mobile, and portable land stations within the PMR service, within frequency bands from 30 MHz to 3,000 MHz.
  • Covered Equipment:
    • Base stations with antenna connectors
    • Mobile stations with antenna connectors
    • Handportable stations with:
      • External antenna connectors
      • Internal or temporary 50 Ω RF connectors
    • Equipment without any RF connector is not within scope
  • Essential Requirements:
    • Frequency error control
    • Maximum power and effective radiated power limits
    • Adjacent and alternate channel power management
    • Restriction on unwanted and spurious emissions
    • Intermodulation attenuation
    • Receiver selectivity and spurious emission controls
  • Environmental Considerations: Requirements must be met across all manufacturer-declared operational environmental conditions.
  • Testing Requirements: Testing must be rigorous and consider both normal and extreme conditions, using defined methods and uncertainty calculations per referenced standards.

Applications

SIST EN 301 166-2 V1.2.1:2007 is widely used in the development, testing, and certification of Land Mobile Radio (LMR) and PMR equipment, such as:

  • Public safety and emergency services radio systems
  • Industrial communication networks (utilities, transport, logistics)
  • On-site communications for commercial sectors (construction, manufacturing)
  • Civilian government operations requiring reliable narrowband communication
  • Manufacturers and importers seeking CE marking for radio equipment within the EU

Complying with this standard ensures interoperability, minimizes radio interference, and meets regulatory requirements for EMC and spectrum management, facilitating access to European and national markets.

Related Standards

For complete compliance and product development, the following related standards are important:

  • EN 301 166-1: Defines technical characteristics and measurement methods for PMR radio equipment on narrow band channels
  • Directive 1999/5/EC (R&TTE Directive): Lays down essential requirements for radio equipment and telecommunications terminal equipment (being replaced by RED 2014/53/EU)
  • EN 301 489 Series: Standards for electromagnetic compatibility (EMC) for radio equipment and services
  • EG 201 399: Provides a modular structure for standards under the R&TTE Directive
  • ETSI TR 100 028: Guidelines for measurement uncertainty

Conclusion

SIST EN 301 166-2 V1.2.1:2007 is vital for ensuring that land mobile service radio equipment achieves electromagnetic compatibility and efficient spectrum use, reducing the risk of interference and ensuring reliable communication across critical sectors. Adhering to this harmonized standard streamlines market approval throughout Europe and supports high-quality, robust radio communication systems in diverse and demanding environments.

The present document has been produced by ETSI in response to a mandate from the European Commission issued
under Council Directive 98/34/EC [3] (as amended) 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 [1] of the European Parliament and
of the Council of 9 March 1999 on radio equipment and telecommunications terminal equipment and the mutual

In the present document different requirements are given for the different radio frequency bands, environmental
conditions and types of equipment where appropriate.
In the present document, data transmission systems are defined as systems which transmit and/or receive data and/or
digitized voice. The equipment comprises a transmitter and associated encoder and modulator and/or a receiver and
associated demodulator and decoder.
The present document covers equipment which may use constant envelope or non-constant envelope modulation.
The types of equipment covered by the present document are as follows:

- handportable stations:
a) either fitted with an antenna connector; or
b) without an external antenna connector but fitted with a permanent internal or a temporary internal
50 Ω RF connector which allows access to the transmitter output and the receiver input.
Handportable station equipment without an external or internal Radio Frequency (RF) connector and without the
possibility of having a temporary internal 50 Ω RF connector is not covered by the present document.
The present document is intended to cover the provisions of article 3.2 of Directive 1999/5/EC [1] (R&TTE Directive),
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.
