SIST EN 301 166-2 V1.2.1:2007 is a harmonized European standard for PMR radio transmitters and receivers used in the land mobile service. It applies to analogue and/or digital speech and data equipment operating on narrow band channels with an antenna connector, and it supports assessment of the essential requirements in Article 3.2 of the R&TTE Directive. In practice, it is the document manufacturers, test labs and conformity assessors use to check spectrum use, transmitter emissions and receiver performance for this equipment class.

What does SIST EN 301 166-2 V1.2.1:2007 specify?

SIST EN 301 166-2 V1.2.1:2007 specifies the harmonized EN requirements for radio equipment in the Private Mobile Radio (PMR) land mobile service that operates on narrow band channels. It sets the compliance framework for equipment intended to use spectrum efficiently and avoid harmful interference.

The scope covers transmit and receive operation in the 30 MHz to 3 000 MHz range, for speech and/or data, including systems that transmit and/or receive data or digitized voice. The document also recognizes constant envelope and non-constant envelope modulation.

The standard covers these equipment types:

• base station - fitted with an antenna connector
• mobile station - fitted with an antenna connector
• handportable station - fitted with an antenna connector, or fitted with a permanent internal or temporary internal 50 Ω RF connector that gives access to transmitter output and receiver input

Handportable station equipment without an external antenna connector, an internal RF connector, or the possibility of a temporary internal 50 Ω RF connector is outside the covered equipment types.

What are the key requirements of SIST EN 301 166-2 V1.2.1:2007?

SIST EN 301 166-2 V1.2.1:2007 sets transmitter and receiver limits, then ties each requirement to a test route in clause 5 and Annex A. For a user, the main task is to identify the equipment class, apply the right antenna arrangement, and verify the listed limits under the declared operating environment.

Environmental profile and special antenna cases

Clause 4.1 requires the manufacturer to declare the environmental profile, and the equipment must comply within the boundary limits of that declared operating environment. That matters because test results only count for the environmental conditions the product is actually designed to meet.

For equipment without an external antenna connector but with a permanent internal or temporary internal 50 Ω RF connector, clause 4 says additional measurements are made with the antenna connected to the station, not through the connector. The extra checks are transmitter effective radiated power, transmitter radiated spurious emissions, receiver maximum usable sensitivity by field strength, and receiver spurious radiations.

Transmitter requirements

Clause 4.2 covers frequency error, maximum power (PX) conducted, maximum effective radiated power, adjacent and alternate channel power, unwanted emissions in the spurious domain, intermodulation attenuation, transient power, and transmitter timeout timer. These are the core checks that show whether the transmitter stays on frequency, stays within power limits, and does not create interference outside its assigned channel.

For base station equipment, intermodulation attenuation is included. For the transmitter timeout timer, compliance is by declaration, and the timer value depends on the class and use of the equipment. The note gives 180 seconds for equipment operating in the 446.1 MHz to 446.2 MHz range.

Receiver requirements

Clause 4.3 covers maximum usable sensitivity, co-channel rejection, adjacent channel selectivity, spurious response rejection, intermodulation response rejection, blocking or desensitization, and spurious radiations. These requirements show whether the receiver can hear wanted signals while resisting interference from nearby or strong unwanted signals.

For duplex equipment, clause 4.3 adds receiver desensitization and spurious response rejection with simultaneous transmission and reception. In practice, that means a product that transmits and receives at the same time must be checked in the condition it will actually face in service.

Testing, measurement uncertainty and result interpretation

Clause 5 requires tests under representative points within the declared environmental profile, and normal and extreme test conditions where stated. It also points to the test power source and sample selection requirements in EN 301 166-1.

Clause 5.2 says the measured value against the corresponding limit is what decides compliance, and the test report must include measurement uncertainty for each parameter. The uncertainty must be at or below the figures in EN 301 166-1, and the values are based on TR 100 028 with a 95% confidence level. For a laboratory, this means uncertainty is part of the compliance evidence, not an optional note.

Essential and other test suites

Clause 5.3 lists the essential test suites for frequency error, output power, effective radiated power, adjacent and alternate channel power, spurious emissions, intermodulation attenuation, transient power, and receiver spurious radiations. Clause 5.4 lists other test suites for receiver sensitivity, co-channel rejection, adjacent channel selectivity, spurious response rejection, intermodulation response rejection and blocking or desensitization.

Annex A links each essential requirement to a test specification and marks whether the requirement is unconditional or conditional. For conformity work, this is the map that tells a lab or manufacturer which measurements are needed for the claimed feature set.

What terms does SIST EN 301 166-2 V1.2.1:2007 define?

SIST EN 301 166-2 V1.2.1:2007 uses the definitions, symbols and abbreviations from the R&TTE Directive and EN 301 166-1. The terms below are the ones a reader is most likely to meet when applying the standard.

• Private Mobile Radio (PMR) - the service area covered by the standard, used for land mobile radio stations.
• Channel separations (CSP) - the narrow spacing between channels that this standard targets, below 10 kHz.
• Channel Bandwidths (CBW) - the channel widths allowed by National Administrations for these systems.
• Radio Frequency (RF) - the signal domain used for the antenna connector and the 50 Ω RF connector references.
• Push-to-talk (PTT) - the key action that starts the transmitter timeout timer when pressed.
• Duplex equipment - equipment that provides simultaneous transmission and reception.
• Handportable station - a portable station with an antenna connector, or with an internal or temporary internal 50 Ω RF connector.

Who uses SIST EN 301 166-2 V1.2.1:2007?

SIST EN 301 166-2 V1.2.1:2007 is used by radio equipment manufacturers, test laboratories, and regulatory compliance teams working on PMR products. It is also useful for buyers and quality managers who need to know what evidence a supplier should provide.

Design engineers use it to set transmitter stability, power, emissions and receiver performance targets. Test labs use it to plan compliance measurements and record uncertainty. Conformity assessors use Annex A and clause 5 to link product claims to the relevant test route.

What changed in SIST EN 301 166-2 V1.2.1:2007 from the previous edition?

The history shows V1.1.1 as an earlier publication from December 2001 and V1.2.1 as the July 2007 publication. The document history in this page does not state specific technical changes.

Which standards are used with SIST EN 301 166-2 V1.2.1:2007?

The standard works with EN 301 166-1, which supplies the shared technical characteristics, methods of measurement, limits, definitions and test clauses used throughout Part 2. Clause 3 says the definitions, symbols and abbreviations from EN 301 166-1 apply here as well.

Directive 1999/5/EC, the R&TTE Directive, is the legal basis for the essential requirements addressed by this harmonized standard. Directive 98/34/EC is named in the foreword as the mandate context for producing the standard.

What does the SIST EN 301 166-2 V1.2.1:2007 document contain?

SIST EN 301 166-2 V1.2.1:2007 contains the scope, references, definitions, technical requirements and compliance testing framework for narrow-band PMR radio equipment. Clause 4 sets the transmitter and receiver requirements, while clause 5 explains how to test them and how to interpret the results.

It also contains Annex A, which is the HS-RTT table linking each essential requirement to its test specification and showing whether the requirement is conditional or unconditional. Annex B provides the title in official languages, and Annex C lists the bibliography.

The document includes specific measurement arrangements for equipment without an external antenna connector, special handling for duplex equipment, and a transmitter timeout timer rule for certain equipment classes. It also gives the measurement uncertainty approach used in test reports, which is important when results are close to a limit.
