SRD-CEPT/ERC 70-03 Recommendation relating to the use of Short Range Devices (SRD)

Recommendation adopted by the Frequency Management, Radio Regulatory and Spectrum Engineering Working Groups

Edition of April 28, 2000

Foreword

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 R&TTE Directive.

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 still have national allocations 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.

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

INTRODUCTION

The CEPT has adopted Recommendations to deal with low power devices, and specific short range devices. The European Telecommunications Standards Institute (ETSI) has now developed harmonised standards and standards for the majority of these devices. Other standards or technical specifications might be applicable within the framework of the R&TTE Directive.

The term "Short Range Device" (SRD) is intended to cover the radio transmitters which provide either unidirectional or bi-directional communication and 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. Due to the many different services provided by these devices, no description can be exhaustive, however, the following categories are amongst those covered:

Telecommand and Telecontrol

Telemetry

Alarms

Speech and Video.

See cover sheet for current status of Recommendation.

This Recommendation describes the spectrum management requirements for SRDs relating to allocated frequency bands, maximum power levels, equipment antenna, channel spacing, duty cycle, licensing and free circulation. In addition for CEPT countries which have not implemented the R&TTE Directive it also sets out the conformity assessment and marking requirements. However, for CEPT countries that have implemented the R&TTE Directive, art.12 (CE-marking) which states that " any other marking may be affixed to the equipment provided that the visibility and legibility of the CE-marking is not hereby reduced" and art. 7.2 which states that "member states may restrict the putting into service of radio equipment only for reasons related to the effective and appropriate use of the radio spectrum, avoidance of harmful interference or matters relating to public health" apply.

Appendix 1 Table 1 lists the applications covered by this Recommendation. Tables 2 to 7 in Appendix 1 list parameters relevant to these applications. In Table 6 only the last line is applicable in countries implementing the R&TTE Directive. The Tables in the following annexes give the possible combinations which may be utilised for different applications. For example, in Annex 1 for the frequency band 40.660-40.700 MHz as mentioned in the fourth row of the first column, equipment may operate with maximum radiated power level 8 (i.e., 10 mW e.r.p.).

Equipment in the frequency band 61.0-61.5 GHz may operate with maximum radiated power level 11 (i.e., 100 mW e.i.r.p.). In neither case are individual licences required and both antenna type 1 (integral antenna) and type 2 (dedicated antenna) may be applied. The same allotment applies to channel spacing, duty cycle, and for countries which have not implemented the R&TTE directive conformity assessment, marking and free circulation.

Relevant ERC Decisions and standards produced by ETSI are mentioned in Appendix 2 of this Recommendation for information purposes. Relevant ETSI Standards are also mentioned by their relevant (ETS/EN) number in the corresponding annexes. However, this list is not necessarily exhaustive and other standards or technical specifications may be applicable. For countries having implemented the R&TTE Directive its art. 10 procedures will then be applied for conformity assessment where either harmonised standards or with the involvement of a Notified Body also other standards and specifications may be applicable. Further details can be found on the relevant EC and the ERO web sites (www.ero.dk).
