Foreword This European Standard (Tele
32、communications senes) has been produced by ETSI Technical Committee Electromagnetic compatibility and Radio spectrum Matters (ERM). The present dociunent has been produced by ETSI in response to a mandate from the European Commission issued under Council Directive 98/34/EC (as amended) laying down a
33、 procedure for the provision of information in the field of technical standards and regulations. The present document together with ETS 300 683, is intended to become a Harmonized Standard, the reference of which will be published in the Official Jod of the European Communities referencing the Counc
34、il Directive on the approximation of the laws of the Member States relating to electromagnetic compatibility (“the EMC Directive“) (89/336/EEC as amended). Technical specifications relevant to the EMC Directive are given in annex G. As a result of ameeting between CEN, CEPT, ETSI, and the European C
35、ommission on 29 June 1998, the existing work item was split as follows: - EN 300 674, supporting the CEN TC 278 RTIT system; - ES 200 674-1, supporting RTIT systems with lower data rates; - ES 200 674-2, supporting RTIT systems with higher data rates.

37、-02) Initial road to Vehicle systems 5,800 GHz + 2,5 MHz Channel 1 5,800 GHz - 2,5 MHz Channel 2 Channel 4 Channel 3 introduction Multi lane road junctions (options) 5,810 GHz - 2,5 MHz 5,810 QHz + 2,5 MHz The present document was drafted on the assumption that type test measurements, perfomed in an
38、 accredited test laboratory, 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 with CEPT/ERC Recommendation 70-03 3. The present document specifies the requirements for a dedic
39、ated 5,8 GHz short range microwave link intended for a European wide data communication system for Road Transport and Traffic Telematics (R“) applications. RlT systems for Europe-wide use are specified by CEN. The necessary set of radio parameters for the support of ENV 12253 i is included in the pr
40、esent document. The parameters might be subject to changes if necessary and when other RTTT systems specified by CEN require this. The RSU transmitter operates on a non-exclusive basis on frequencies depending on the declared application according to ERC/DEC(92)02 2. A channel spacing of 5 MHz is us
41、ed for channels 1,2,3 and 4, see table 1. In order to permit the greatest freedom of design of equipment, whilst protecting other radio services from interference, a balance is required between the permitted range of frequencies on which the equipment may be used, and its frequency stability and mod
42、ulation characteristics. The present document specifies the operational frequencies and system bandwidths. However, the present document does not fully describe the permitted range of optional frequencies as these are covered by national regulations. The optional range of frequencies offered should
43、be specified on each type approval certificate issued. Clauses 1 and 3 give a general description of the types of equipment covered by the present document and the definitions and abbreviations used. Clause 4 gives general requirement in order that type tests may be ded out and any markings on the e
44、quipment to be provided by the manufacturer. Clauses 5 and 6 specify the test conditions. Clauses 7 and 8 specify the limits of the parameters which are required to be tested for the RSU transmitters and receivers 1. These limits have been chosen to minimize harmfui interference to and fromother equ
45、ipment and services. These clauses also spec how the equipment is to be tested and the conditions which are applied. Clause 9 specifies the limits of the parameters which are required to be tested for transponders. These limits are chosen to restrict the access to and radiation fromtransponders. Det
46、ails on the test methods for the transponders are also specified. Clause 10 specifies the maximummeasurement uncertainty values. Annex A provides normative specifications concerning test sites for radiated measurements. Annex B provides normative descriptions of measurement methods for radiated meas
47、urements. Annex C provides normative descriptions of alternative measurement methods for receivers. Annex D contains technical specification relevant to the EMC Directives. ETSI 9 EN 300 674 V1.l.l (1999-02) 1 Scope The present document specifies radio parameters which are necessary for the efficien
48、t use of the radio spectrum and for the purpose of type approval. This includes methods of measurements for verifying the limits stated in the present document. The present document applies to 5,8 GHz Short Range Devices (SRs) for use in Road Transport Traffic and Telematics (R“): - with a Radio Fre
49、quency - for data transmission only; - output connection and specified antenna or with an integai antenna; operathg on radio frequencies in the 5 725 MHz to 5 875 MHz Industrial, ScienWic and Medical (EM) band. The applicability of the present document covers both the Road Side Units (RSUs) and the On Board Units (OBUS) with transceivers and transponders. The present document does not necessarily include all the characteristics which may be required by a user, nor does it necessariiy represent the optimum performance achievable. The present document complies with ERC/D
