7 6 TS V4.0.0 ( ) 1 Scope The present document describes the Radio Frequency (RF) tests for GSM 450, GSM 480, GSM 900 and DCS 1800 repeaters which receive, amplify, and retransmit a received Mobile Station (MS) signal in the GSM MS transmit band and simultaneously receive, amplify and retransmit a received Base Transceiver Station (BTS) RF signal in the GSM BTS transmit band. The present document is applicable to repeaters meeting the requirements of either GSM Phase 2 or GSM Phase 2+. Unless otherwise stated, all tests are applicable to repeaters meeting Phase 2 and/or Phase 2+ GSM requirements, because the requirements of the Phase 2 and Phase 2+ core GSM specifications which are referenced in the test are consistent. Most differences between Phase 2 and Phase 2+ requirements represent Phase 2+ features which are optional for the BSS to support. 2 References The following documents contain provisions which, through reference in this text, constitute provisions of the present document.

8 7 TS V4.0.0 ( ) [12] ETR 028: "Uncertainties in the measurement of mobile radio equipment characteristics". 3 Definitions and abbreviations 3.1 Definitions For the purposes of the present document, the following terms and definitions apply: broadband repeater: repeater which is designed for operation on any combination of ARFCNs (up to a specified maximum number) within the operating band of the repeater. channelized repeater: repeater which is designed for operation on a specified subset of ARFCNs within the operating band of the repeater. The subset of ARFCNs may be determined during the manufacture of the repeater, or may be programmable. repeater system using frequency shift: frequency shifting repeater consists of two different elements, a master unit close to the BTS and at least one remote unit close to the area to be covered. The master unit amplifies the channels from the BTS and shifts them to different GSM channels. In the remote unit the shifted channels from the master unit will be transferred back to the original channels and amplified. This is valid for the downlink signals as well as for the uplink signals.gsm: Unless otherwise specified, references to GSM include both GSM450, GSM 480, GSM 900 and DCS repeater: bi-directional Radio Frequency (RF) amplifier which can amplify and transmit a received Mobile Station (MS) signal in the GSM MS transmit band, simultaneously it can amplify and transmit a received Base Transceiver Station (BTS) RF signal in the GSM BTS transmit band. spurious emissions: emissions at frequencies other than those of the carrier and sidebands associated with normal modulation and switching. 3.2 Abbreviations For the purposes of the present document, the following abbreviations apply: BTS MS RF Base Transceiver Station Mobile Station Radio Frequency Abbreviations used within the GSM specifications are given in ETR 350 (GSM 01.04) [1]. 4 General A repeater can be designed to amplify the whole transmit RF band or just a part of the band. In the latter case the repeater can be either Broadband, with frequency band selective filtering, or channelized, with channel selective filtering. 4.1 Radio frequency bands A repeater, as a bi-directional amplifier, can amplify and transmit a received MS signal in the MS transmit band, simultaneously it can amplify and transmit a received BTS signal in the BTS transmit band. The relevant MS and BTS transmit bands for the present document, which is a subset of the MS and BTS transmit bands as defined in GSM [6], are given in table 1.

12 11 TS V4.0.0 ( ) 5.4 Reference requirement GSM [6], annex E. 6 Intermodulation attenuation 6.1 Test purpose To verify that the level of intermodulation products, generated in non-linear elements of the repeater, in the presence of two RF input signals, do not exceed the specified limits. 6.2 Test case The repeater shall be set to maximum gain. Two continuous sinusoidal RF signals shall be fed to the input antenna port of the repeater using a combining device. The frequencies of both RF signals shall be within the repeater's operating band. The spacing between both RF signals shall be the minimum possible spacing applied in a network, i.e. 600 khz. The level of both RF input signals shall be increased, until the maximum rated output power per channel, as declared by the manufacturer, is reached. In case of a repeater only supporting one channel, one RF input signal shall be set to the operating frequency and the other RF input signal at an offset of 400 khz to either side successively. In this case the input signal at the repeaters operating frequency shall be increased, until the maximum rated output power per channel, as declared by the manufacturer, is reached. The second signal shall be set to the same input level. The level of the third order intermodulation products shall be measured by means of a selective measurement device presenting to the repeater a load with an impedance of 50 ohms. The test shall be repeated with both RF input signals increased by 10 db each. NOTE: In this case, the automatic gain (level) control may reduce the gain to a value less than maximum gain in order to keep the maximum rated output power per channel, as declared by the manufacturer. An average power measurement shall be performed using a bandwidth of 3 khz. The measurements shall apply to all antenna ports of the repeater. Test environment: Normal 6.3 Conformance requirement The maximum level of intermodulation product shall be not greater than: dbm (250 nw) in the frequency band 9 khz to 1 GHz; dbm (1µW) in the frequency band 1 GHz to 12,75 GHz. 6.4 Reference requirement GSM [6] annex E.

This test shall also check the net gain at harmonic frequencies. 7.2 Test case The repeater shall be set to maximum gain. In case of a channel selective repeater, two of the channel selective modules shall be set to the lowermost and the uppermost ARFCN within the repeater's operating band. A continuous sinusoidal RF signal shall be fed successively at frequency offsets Y from the edges of the relevant MS or BTS transmit frequency band into the relevant input port of the repeater. The frequency offsets Y shall have the following values: 400 khz, 600 khz, 800 khz, 1 MHz, 5 MHz, 10 MHz, 15 MHz, 20 MHz. This shall be repeated with an RF input signal successively set to all harmonic frequencies of the repeaters operating band up to GHz (i.e. multiples of the centre frequency of the repeaters operating band up to 12,75 GHz). The power level of the RF input signal shall be at least 5 db below the power level which would produce, when applied within the operating band, maximum rated output power, as declared by the manufacturer. This is to ensure that the equipment is operating in the linear output range. The average output power in each case shall be measured and the net gain shall be recorded. The measurements shall apply to all antenna ports of the repeater. Test environment: Normal Extreme temperature 7.3 Conformance requirement The net gain in both directions through the repeater shall be less than: - 50 db at 400 khz offset and greater; - 40 db at 600 khz offset and greater; - 35 db at 1 MHz offset and greater; - 25 db at 5 MHz offset and greater; from the edges of the relevant MS or BTS transmit bands. 7.4 Reference requirement GSM [6], annex E. 8 Frequency error 8.1 Test purpose This clause applies only to repeater systems using frequency shift and describes the test of the frequency error.
14 13 TS V4.0.0 ( ) 8.2 Test case The repeater system shall be levelled according to the recommendations of the manufacturer. For the purpose of the frequency synchronisation of the repeater system it might be necessary to connect the system to a BTS or an equivalent test equipment like a mobile tester. In all cases an accurate frequency synchronisation source has to be used to synchronise the measurement setup. The test of the repeater system shall be performed at the lowest and the highest ARFCN supported by the repeater system. For the measurement of the frequency error a continuous, sinusoidal and synchronised RF signal shall be fed successively at a frequency of the relevant MS or BTS transmit frequency band into the relevant input port of the repeater. The power level of the RF input signal shall be at least 5 db below the power level which would produce, when applied within the operating band, maximum rated output power, as declared by the manufacturer. This is to ensure that the equipment is operating in the linear output range. The average output frequency shall be measured with a frequency counter. The frequency error of single elements within the repeater system such as master unit or remote unit may be measured as well. Test environment: Normal Extreme temperature 8.3 Conformance requirement The average frequency error of the repeater system shall not exceed 0,1 ppm. If tested, the average frequency error of a single repeater shall not exceed 0,05 ppm. 8.4 Reference requirement GSM [6], annex E. 9 Modulation accuracy at GMSK modulation 9.1 Test purpose This clause applies only to repeater systems using frequency shift and describes the test of the phase error. 9.2 Test case The repeater system shall be levelled according to the recommendations of the manufacturer. For the purpose of the frequency synchronisation of the repeater system it might be necessary to connect the system to a BTS or an equivalent test equipment like a mobile tester. In all cases an accurate frequency synchronisation source has to be used to synchronise the measurement setup. For the measurement of the phase error a continuous and synchronised GMSK signal modulated with a pseudo random bit sequence shall be fed successively at one frequency of the relevant MS or BTS transmit frequency band into the relevant input port of the repeater. The power level of the RF input signal shall be at least 5 db below the power level which would produce, when applied within the operating band, maximum rated output power, as declared by the manufacturer. This is to ensure that the equipment is operating in the linear output range. The phase trajectory shall be measured at the equivalent output of the repeater system and the calculation of the phase error shall be performed according to GSM [9] or GSM [10]. The phase error of single elements within the repeater system such as master unit or remote unit may be measured as well.
15 14 TS V4.0.0 ( ) The GMSK signal source shall have a phase error below the following values: - 5 degrees rms; - 20 degrees peak. Test environment: Normal Extreme temperature 9.3 Conformance requirement The phase error of a complete repeater system shall not exceed: - 7 degrees rms; - 28 degrees peak. If tested, the phase error of a single repeater unit shall not exceed: degrees rms; degrees peak. 9.4 Reference requirement GSM [6], annex E. 10 Modulation accuracy at 8-PSK modulation 10.1 Test purpose This clause applies only to repeater systems supporting 8-PSK modulation and describes the test of the modulation accuracy Test case The repeater system shall be levelled according to the recommendations of the manufacturer. For the purpose of the frequency synchronisation of the repeater system it might be necessary to connect the system to a BTS or an equivalent test equipment like a mobile tester. In all cases an accurate frequency synchronisation source has to be used to synchronise the measurement setup. For the measurement of the modulation accuracy a continuous and synchronised 8-PSK signal modulated with a pseudo random bit sequence shall be fed successively at one frequency of the relevant MS or BTS transmit frequency band into the relevant input port of the repeater. The power level of the RF input signal shall be at least 5 db below the power level which would produce, when applied within the operating band, maximum rated output power, as declared by the manufacturer. This is to ensure that the equipment is operating in the linear output range. The EVM shall be measured at the equivalent output of the repeater system and the calculation of the EVM shall be performed according to GSM [10]. The modulation accuracy of single elements within the frequency shifting repeater system such as master unit or remote unit may be measured as well. Test environment: Normal Extreme temperature
16 15 TS V4.0.0 ( ) 10.3 Conformance requirement For a single repeater with no shift in frequency the EVM shall not exceed: - 8 % RMS. For a complete repeater system using frequency shift the EVM shall not exceed: - 14,5 % RMS. If tested, the EVM of a single repeater unit in a frequency shifting repeater system shall not exceed: - 12 % RMS.10.4 Reference requirement GSM [6], annex E.
17 16 TS V4.0.0 ( ) Annex A (informative): Testing of gain for part band repeaters A.1 Rationale for this test The normative provisions of the present document specify the out-of band gain relative to the edge of one of the GSM bands specified in clause 4.1. The purpose of this informative annex is to define a test method which may be used to measure the out-of-band gain for a repeater which is designed to operate only over part of one of these bands. This test may be used for acceptance testing or for regulatory purposes. Since GSM does not specify the out-of-band gain requirements within a GSM band for a such a repeater, the performance requirements for the repeater must be agreed prior to this test being performed. Normally, the requirements for the uplink and downlink directions will be similar, but with the frequencies offset by 45 MHz or 95 MHz. A.2 Gain outside operating band A.2.1 Test purpose To determine the net gain of the repeater outside its specified operating band (or bands), when this is less than a GSM band defined in clause 4.1 of the present document. The requirements of clause 7 of the present document shall always be met, whether or not this test is also performed. This test is not a normative requirement of the present document. A.2.2 Test case The repeater shall be set to maximum gain. In case of a channel selective repeater, two of the channel selective modules shall be set to the lowermost and the uppermost ARFCN within the repeaters operating band. A continuous sinusoidal RF signal shall be fed successively at each specified frequency into the relevant input port of the repeater. The power level of the RF input signal shall be at least 5 db below the power level which would produce, when applied within the specified operating band, maximum rated output power, as declared by the manufacturer. This is to ensure that the equipment is operating in the linear output range. The average output power in each case shall be measured and the net gain shall be recorded. The measurements shall apply to all antenna ports of the repeater. Test environment: Normal Extreme temperature A.2.3 Conformance requirement At each frequency specified to be measured, the gain through the repeater shall be less than the specified value.
