Foreword This Candidate Harmonized European Standard (Telecommunications series) has been produced by ETSI Technical Committee Electromagnetic compatibility and Radio spectrum Matters (ERM). The present document has been produced by ETSI in response to a mandate from the European Commission issued under Council Directive 98/34/EC [5] (as amended) laying down a procedure for the provision of information in the field of technical standards and regulations. The present document is intended to become a Harmonized Standard, the reference of which will be published in the Official Journal of the European Communities referencing the Directive 1999/5/EC [1] of the European Parliament and of the Council of 9 March 1999 on radio equipment and telecommunications terminal equipment and the mutual recognition of their conformity ("the R&TTE Directive [1]"). Technical specifications relevant to Directive 1999/5/EC [1] are given in annex A.

Introduction The present document is part of a set of standards designed to fit in a modular structure to cover all radio and telecommunications terminal equipment under the R&TTE Directive [1]. Each standard is a module in the structure. The modular structure is shown in figure 1.

The left hand edge of the figure 1 shows the different clauses of article 3 of the R&TTE Directive [1]. For article 3.3 various horizontal boxes are shown. Dotted lines indicate that at the time of publication of the present document essential requirements in these areas have to be adopted by the Commission. If such essential requirements are adopted, and as far and as long as they are applicable, they will justify individual standards whose scope is likely to be specified by function or interface type. The vertical boxes show the standards under article 3.2 for the use of the radio spectrum by radio equipment. The scopes of these standards are specified either by frequency (normally in the case where frequency bands are harmonized) or by radio equipment type. For article 3.1b the figure shows EN 301 489, the multi-part product EMC standard for radio used under the EMC Directive [2].
For article 3.1a figure 1 shows the existing safety standards currently used under the LV Directive [3] and new standards covering human exposure to electromagnetic fields. New standards covering acoustic safety may also be required. The bottom of the figure shows the relationship of the standards to radio equipment and telecommunications terminal equipment. A particular equipment may be radio equipment, telecommunications terminal equipment or both. A radio spectrum standard will apply if it is radio equipment. An article 3.3 standard will apply as well only if the relevant essential requirement under the R&TTE Directive [1] is adopted by the Commission and if the equipment in question is covered by the scope of the corresponding standard. Thus, depending on the nature of the equipment, the essential requirements under the R&TTE Directive [1] may be covered in a set of standards. The modularity principle has been taken because: - it minimizes the number of standards needed. Because equipment may, in fact, have multiple interfaces and functions it is not practicable to produce a single standard for each possible combination of functions that may occur in an equipment; - it provides scope for standards to be added: - under article 3.2 when new frequency bands are agreed; or - under article 3.3 should the Commission take the necessary decisions without requiring alteration of standards that are already published; - it clarifies, simplifies and promotes the usage of Harmonized Standards as the relevant means of conformity assessment.

ETSI ETSI EN 300 328 V1.5.1 (2004-08) 11 4.2 Modulation The manufacturer shall state the modulation characteristics of the equipment to be tested. For the purpose of deciding which level of power density applies to the equipment, the present document defines two categories of equipment: equipment conforming to the stated characteristics of FHSS modulation (see clause 4.2.1) and equipment not conforming to these characteristics. The latter category includes equipment using DSSS modulation (see clause 4.2.2). 4.2.1 FHSS modulation FHSS modulation shall make use of at least 15 well defined, non-overlapping channels or hopping positions separated by the channel bandwidth as measured at 20 dB below peak power. The dwell time per channel shall not exceed 0,4 s. While the equipment is operating (transmitting and/or receiving) each channel of the hopping sequence shall be occupied at least once during a period not exceeding four times the product of the dwell time per hop and the number of channels. Systems that meet the above constraints shall be tested according to the requirements for FHSS modulation. 4.2.2 DSSS and other forms of modulation For the purposes of the present document, other forms of modulation which do not satisfy the constraints of the specification given in clause 4.2.1, shall be considered equivalent to DSSS modulation. Systems using these other forms of modulation shall be considered equivalent to DSSS systems and shall be tested according to the requirements for DSSS modulation.
4.3 Technical requirements 4.3.1 Effective radiated power 4.3.1.1 Definition The effective radiated power is defined as the total power of the transmitter. 4.3.1.2 Limit The effective radiated power shall be equal to or less than -10 dBW (100 mW) e.i.r.p. This limit shall apply for any combination of power level and intended antenna assembly.
4.3.2 Maximum spectral power density 4.3.2.1 Definition The maximum spectral power density is defined as the highest level of power in Watts per Hertz generated by the transmitter within the power envelope.
4.3.2.2 Limit For equipment using FHSS modulation, the maximum spectral power density shall be limited to -10 dBW (100 mW) per 100 kHz e.i.r.p. For equipment using other types of modulation, the maximum spectral power density shall be limited to -20 dBW (10 mW) per MHz e.i.r.p. SIST EN 300 328 V1.5.1:2005

ETSI ETSI EN 300 328 V1.5.1 (2004-08) 12 4.3.3 Frequency range 4.3.3.1 Definition The frequency range of the equipment is determined by the lowest and highest frequencies occupied by the power envelope. fH is the highest frequency of the power envelope: it is the frequency furthest above the frequency of maximum power where the output power drops below the level of -80 dBm/Hz e.i.r.p. spectral power density (-30 dBm if measured in a 100 kHz bandwidth). fL is the lowest frequency of the power envelope; it is the frequency furthest below the frequency of maximum power where the output power drops below the level equivalent to -80 dBm/Hz e.i.r.p. spectral power density (or -30 dBm if measured in a 100 kHz bandwidth). For a given operating frequency, the width of the power envelope is (fH - fL). In equipment that allows adjustment or selection of different operating frequencies, the power envelope takes up different positions in the allocated band. The frequency range is determined by the lowest value of fL and the highest value of fH resulting from the adjustment of the equipment to the lowest and highest operating frequencies. 4.3.3.2 Limit For all equipment the frequency range shall lie within the band 2,4 GHz to 2,4835 GHz (fL > 2,4 GHz and fH < 2,4835 GHz).
4.3.4 Transmitter spurious emissions 4.3.4.1 Definition Transmitter spurious emissions are emissions outside the frequency range(s) of the equipment as defined in clause 4.3.3.1 when the equipment is in Transmit mode and/or in Standby mode. 4.3.4.2 Limit The spurious emissions of the transmitter shall not exceed the values in tables 2 and 3 in the indicated bands. Table 2: Transmitter limits for narrowband spurious emissions Frequency range Limit when operating Limit when in standby 30 MHz to 1 GHz -36 dBm -57 dBm above 1 GHz to 12,75 GHz -30 dBm -47 dBm 1,8 GHz to 1,9 GHz 5,15 GHz to 5,3 GHz -47 dBm -47 dBm
The above limit values apply to narrowband emissions, e.g. as caused by local oscillator leakage. The measurement bandwidth for such emissions may be as small as necessary to achieve a reliable measurement result. Wideband emissions shall not exceed the values given in table 3. Table 3: Transmitter limits for wideband spurious emissions Frequency range Limit when operating Limit when in standby 30 MHz to 1 GHz -86 dBm/Hz -107 dBm/Hz above 1 GHz to 12,75 GHz -80 dBm/Hz -97 dBm/Hz 1,8 GHz to 1,9 GHz 5,15 GHz to 5,3 GHz -97 dBm/Hz -97 dBm/Hz

Table 4: Narrowband spurious emission limits for receivers Frequency range Limit 30 MHz to 1 GHz -57 dBm above 1 GHz to 12,75 GHz -47 dBm
The above limit values apply to narrowband emissions, e.g. as caused by local oscillator leakage. The measurement bandwidth for such emissions may be as small as necessary to get a reliable measurement result. Wideband emissions shall not exceed the values given in table 5.

ETSI ETSI EN 300 328 V1.5.1 (2004-08) 14 5.2 Requirements for the test modulation The test modulation used should be representative of normal use of the equipment. Where the equipment is not capable of continuous RF transmission, the test modulation shall be such that: - the generated RF signal is the same for each transmission; - transmissions occur regularly in time; - sequences of transmissions can be repeated accurately. The same test modulation shall be used for all measurements on the same equipment. For frequency hopping systems the equipment should allow the hop frequencies required by the present document to be selected. 5.3 Test conditions, power supply and ambient temperatures 5.3.1 Normal and extreme test conditions Testing shall be performed under normal test conditions and where stated in the test procedures for essential radio test suites (see also clause 5.7), under extreme conditions (see clause 5.3.4). Exceptions to the measurement procedures given in this clause shall be recorded.
5.3.2 Power sources 5.3.2.1 Power sources for stand-alone equipment During testing, the power source of the equipment shall be replaced by a test power source capable of producing normal and extreme test voltages as specified in clauses 5.3.3.2 and 5.3.4.2. The internal impedance of the test power source shall be low enough for its effect on the test results to be negligible. For the purpose of tests, the voltage of the power source shall be measured at the input terminals of the equipment. For battery operated equipment the battery shall be removed and the test power source shall be applied as close to the battery terminals as practicable. During tests the power source voltages shall be maintained within a tolerance of ±1 % relative to the voltage at the beginning of each test. The value of this tolerance is critical to power measurements; using a smaller tolerance will provide better measurement uncertainty values. 5.3.2.2 Power sources for plug-in radio devices The power source for testing plug-in radio devices shall be provided by a test jig or host equipment. Where the host equipment and/or the plug-in radio device is battery powered, the battery may be removed and the test power source applied as close to the battery terminals as practicable. 5.3.3 Normal test conditions 5.3.3.1 Normal temperature and humidity The normal temperature and humidity conditions for tests shall be any convenient combination of temperature and humidity within the following ranges: - temperature:
+15°C to +35°C; - relative humidity: 20 % to 75 %. SIST EN 300 328 V1.5.1:2005

The actual values during the tests shall be recorded. 5.3.3.2 Normal power source 5.3.3.2.1 Mains voltage The normal test voltage for equipment to be connected to the mains shall be the nominal mains voltage. For the purpose of the present document, the nominal voltage shall be the voltage(s) for which the equipment was designed. The frequency of the test power source corresponding to the AC mains shall be between 49 Hz and 51 Hz. 5.3.3.2.2 Lead-acid battery power sources used on vehicles When radio equipment is intended for operation from the usual, alternator fed lead-acid battery power source used on vehicles, then the normal test voltage shall be 1,1 times the nominal voltage of the battery (6 V, 12 V, etc.). 5.3.3.2.3 Other power sources For operation from other power sources or types of battery (primary or secondary), the nominal test voltage shall be as stated by the equipment manufacturer. This shall be recorded. 5.3.4 Extreme test conditions 5.3.4.1 Extreme temperatures For tests at extreme temperatures, measurements shall be made in accordance with the procedures specified in clause 5.3.4.3, at the upper and lower temperatures of the range as follows: - temperature:
