Page 7I-ETS 300 440: December 1995ForewordThis Interim European Telecommunication Standard (I-ETS) has been produced by the Radio Equipmentand Systems (RES) Technical Committee of the European Telecommunications Standards Institute(ETSI).Every I-ETS prepared by ETSI is a voluntary standard. This I-ETS contains text concerning type approvalof the equipment to which it relates. This text should be considered as guidance and does not make this I-ETS mandatory.Proposed announcement dateDate of adoption of this I-ETS:13 October 1995Date of latest announcement of this I-ETS (doa):31 March 1996IntroductionThis I-ETS was drafted on the assumption that type test measurements, performed in an accredited testlaboratory, will be accepted by the various national regulatory authorities in order to grant type approval,provided the national regulatory requirements are met. This is in compliance withCEPT/ERC Recommendation 01-06 [1].Clauses 1 and 3 provide a general description on the types of equipment covered by this I-ETS and thedefinitions and abbreviations used. Clause 4 provides a guide as to the number of samples required inorder that type tests may be carried out and any markings on the equipment which the manufacturershould provide.Clauses 5 and 6 provide a description on the test conditions.Clauses 7 and 8 provide the limits of the parameters which are required to be tested. These limits havebeen chosen to minimise harmful interference to other equipment and services. It also provides details onhow the equipment should be tested and the conditions which should be applied.Clause 9 states the maximum measurement uncertainty values.Annex A provides normative specifications concerning radiated measurements.Annex B provides normative description of measurement methods.Annex C provides information on specific applications covered by this I-ETS.SIST I-ETS 300 440:1999

Page 9I-ETS 300 440: December 19951ScopeThis Interim European Telecommunication Standard (I-ETS) covers the minimum characteristics considerednecessary for Short Range Devices (SRDs) in order to make the best use of the available frequencies.This I-ETS does not necessarily include all the characteristics which may be required by a user, nor does itnecessarily represent the optimum performance achievable.This I-ETS applies to SRDs:-either with a Radio Frequency (RF) output connection and specified antenna, or with an integralantenna;-for alarms, identification systems, radiodetermination, telecommand, telemetry etc. applications;-for all types of modulation;-with or without speech;-operating on radio frequencies between 1 and 25 GHz, with peak power levels up to 2 W equivalentisotropically radiated power (eirp).This I-ETS also applies to Low Power Devices (LPDs), as defined in CEPT Recommendation T/R 01-04 [2].This I-ETS is based upon CEPT Recommendations T/R 01-04 [2], T/R 22-04 [3] and T/R 60-01 [4]. It is ageneral standard which may be superseded by specific standards covering specific applications.This I-ETS covers fixed stations, mobile stations and portable stations. If the system includes a transponder,this should be measured together with the transmitter.For regulatory purposes the equipment is divided into three main classes based on frequency range andmaximum radiated output power eirp (see table 1).Table 1: Maximum radiated peak power (eirp)ClassFrequency (GHz)> 1,0 to 5,0> 5,0 to 20,0> 20,0I10 mW25 mW100 mWII (note)500 mW500 mWIII500 mW2 WNOTE:This class is only applicable for reflective transponder systems using the bands according toCEPT Recommendation T/R 60-01 [4].For non-harmonized parameters, national administrations may impose conditions on the type ofmodulation, channel/frequency separations, maximum eirp, equipment marking and the inclusion of anautomatic transmitter shut-off facility, as a condition of the issue of an individual or general licence or as acondition of use under licence exemption. The extreme temperature ranges are fixed and are given insubclause 5.4.1.2.In order to permit the greatest freedom of design of equipment, whilst protecting other radio services frominterference, a balance is required between the permitted range of frequencies on which the equipmentmay be used, and its frequency stability and modulation characteristics. This I-ETS does not specify theoperating frequencies or system bandwidths, these parameters will be covered by national regulations,since these parameters are not harmonised. However, the method to determine the permitted range ofoperating frequencies is to be found in subclause 7.2 of this I-ETS. This range of frequencies should bestated in the test report.SIST I-ETS 300 440:1999
Page 10I-ETS 300 440: December 1995The performance of the equipment submitted for type testing should be representative of the performanceof the corresponding production model. In order to avoid any ambiguity in that assessment, this I-ETScontains instructions for the presentation of equipment for type testing purposes (see subclause 4.1)conditions of testing (see clause 5) and measurement methods, (see clauses 7 and 8).This I-ETS does not cover requirements for radiated emissions below 25 MHz.Additional standards or specifications may be required for equipment such as that intended for directconnection to the Public Switched Telephone Network (PSTN).2Normative referencesThis I-ETS incorporates by dated or undated reference, provisions from other publications. Thesenormative references are cited at the appropriate places in the text and the publications listed hereafter.For dated references, subsequent amendments to or revisions of any of these publications apply to thisI-ETS only when incorporated in it by amendment or revision.
