This Recommendation sets out the general position on common spectrum allocations for Short Range Devices (SRDs) for countries within the CEPT. It is also intended that it can be used as a reference document by the CEPT member countries when preparing their national regulations in order to keep in line with the provisions of the RE Directive (2014/53/EU) .

In using this Recommendation it should be remembered that it represents the most widely accepted position within the CEPT but it should not be assumed that all allocations are available in all countries. An indication of where allocations are not available or where deviations from the CEPT position occur is to be found in Appendix 3.

It should also be remembered that the pattern of radio use is not static. It is continuously evolving to reflect the many changes that are taking place in the radio environment; particularly in the field of technology. Spectrum allocations must reflect these changes and the position set out in this Recommendation is therefore subject to continuous review.

Moreover, many administrations have designated additional frequencies or frequency bands for SRD applications on a national basis that do not conform to the CEPT position set out in this Recommendation.

For these reasons, those wishing to develop or market SRDs based on this Recommendation are advised to contact the relevant national administration to verify that the position set out herein still applies. Any inconsistencies between the national position stated in the implementation table in Appendix 1 of this Recommendation and those national positions stated elsewhere should be brought to the attention of the ECO ( in order that these differences may be resolved.

When selecting parameters for new SRDs, which may have inherent safety of human life implications, manufacturers and users should pay particular attention to the potential for interference from other systems operating in the same or adjacent bands. Manufacturers should advice users on the risks of potential interference and its consequences.

This Recommendation is also electronically available in the EFIS database link.

Information on RE Directive radio equipment classes is available in the EFIS database link.

CEPT has adopted this Recommendation to deal with Short Range Devices and the European Telecommunications Standards Institute (ETSI) has developed harmonised European standards in support of the RE Directive (2014/53/EU) for the majority of these devices.

The term "Short Range Device" (SRD) is intended to cover the radio equipment which have low capability of causing interference to other radio equipment. SRDs use either integral, dedicated or external antennas and all modes of modulation can be permitted subject to relevant standards. SRDs are not considered a "Radio Service" under the ITU Radio Regulations (Article 1).

This Recommendation describes the spectrum management requirements for SRDs relating to allocated frequency bands, maximum power levels, channel spacing or modulation/maximum occupied bandwidth and duty cycle.

Use of SRD devices on board aircraft is allowed under the same conditions provided in the relevant Annex of Recommendation 70-03. CEPT does not address aviation safety aspects. Aircraft manufacturers and aircraft owners should consult the relevant national or regional aviation bodies before installing and using such devices on board aircraft.

Note 1: see also the explanatory document FM(18)113 Annex 47 on 5 GHz RLAN in vehicles (cars, busses, on-board trains, on-board aircraft);

Note 2: see also the explanatory document FM(18)059 Annex 37 related to non-professional Unmanned Aircraft System (UAS) use under general authorisations;

For Short Range Devices individual licenses are normally not required unless this possibility is stated within the relevant Annex.

The following annexes define the regulatory parameters as well as additional information about harmonised standards, frequency issues and important technical parameters. Technical parameters are indicated in the relevant harmonised standard.

Appendix 2 covers the relevant ECC/ERC Decisions, Recommendations, ETSI standards and EC Decisions.

For countries having implemented the RE Directive further details can be found on the Office web sites (link).

The RE Directive (2014/53/EU) can be seen under (link).

Applications for certain short range devices within this Recommendation are subject to EC Decisions including Decision 2006/771/EC (and its amendments) and Decision 2018/1538/EU. These applications are identified by a footnote under “Additional Information” in the relevant Annex which also mentions any derogation that has been agreed. A list of relevant EC Decisions can be found in Appendix 2.

Member States of EU/EFTA may allow, at national level, equipment to operate under more permissive conditions than specified in the EC Decision if permitted by that EC Decision. Equipment which cannot be operated throughout the European Community without restrictions is considered as ‘Class 2’ equipment under the classification related to the 2014/53/EU (RE) Directive.

This Recommendation is designed to assist with frequencies available within CEPT member countries for putting short range device radio equipment into service. It is not intended to limit the possibility for placement of product on the market in those Countries which have adopted the RE Directive.

Note that the following RE Directive radio equipment classes exist:

  1. Class 1: radio equipment that can be operated without any restriction in EU, EEA and EFTA. According to Article 8.1(b) of the RE Directive, it is clarified that no national radio interface specification is required to be notified under the RE Directive.

  2. Class 2: radio equipment subject to restrictions in one or more EU, EEA and EFTA countries, where:

    • the technical parameters are not harmonised through EU, EEA and EFTA;

    • the technical parameters are harmonised through EU, EEA and EFTA and do not fall in above class 1 definition.

Furthermore, the implementing act establishing the equivalence between notified radio interfaces and assigning a radio equipment class (Article 8.2 of the RE Directive) is going to be prepared on the base of these classes.


"The European Conference of Postal and Telecommunications Administrations,


  1. that SRDs in general operate in shared bands and are not permitted to cause harmful interference to radio services;

  2. that in general SRDs cannot claim protection from radio services;

  3. that due to the increasing interest in the use of SRDs for a growing number of applications it is necessary to harmonise frequencies and regulations for these devices;

  4. that there is a need to distinguish between different applications;

  5. that additional applications and associated annexes will be added as necessary;

  6. that maintenance of Appendices 1 and 3 and also the related cross-references in the Annexes may be undertaken by the ECO based on information from administrations;

  7. that information about placing SRD equipment on the market and its use can be obtained by contacting individual administrations, especially with regard to equipment operating in frequencies or frequency bands that may be designated for SRDs by administrations in addition to those covered in this Recommendation;

  8. that for those countries implementing the provisions of this Recommendation, national restrictions in respect of the annexes can be found in Appendix 3;

  9. that comparable technical parameters to those given in this ERC Recommendation are given in the EC Decision 2006/771/EC (as amended) and EC Decision 2018/1538/EU.


  1. that CEPT administrations implement the parameters in accordance with the indications mentioned in the annexes;

  2. that technical parameter limits should not be exceeded by any function of the equipment;

  3. that CEPT administrations should allow visitors from other countries to carry and use their equipment temporarily without any further formalities unless there are national restrictions as shown in Appendix 3."
