1 Scope
The present document describes the Radio Frequency (RF) tests for GSM repeaters (frequency bands according to
clause 4.1) 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.

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.
GSM: Unless otherwise specified, references to GSM include all radio frequency bands according to clause 4.1.
operating band: the frequency range in which GSM operates.
pass band: frequency range that the repeater operates in with operational configuration.
NOTE 1: This frequency range can correspond to one or several consecutive nominal channels. If they are not
consecutive each subset of channels shall be considered as an individual pass band.
NOTE 2: A repeater can have one or several pass bands.
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.
repeater system using frequency shift: repeater system consisting of two different elements, a master unit close to the
BTS and at least one remote unit close to the area to be covered.
NOTE 3: 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.
spurious emissions: emissions at frequencies other than those of the carrier and sidebands associated with normal
modulation and switching.
subchannel power imbalance ratio on downlink: as defined in 3GPP TS 45.004 [21].
3.2 Abbreviations
For the purposes of the present document, the following abbreviations apply:
BTS Base Transceiver Station
MS Mobile Station
RF Radio Frequency
SCPIR_DL Subchannel Power Imbalance Ratio on DownLink
Abbreviations used within the GSM specifications are given in 3GPP TR 21.905 [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.

3GPP TS 51.026 version 13.0.0 Release 13 8 ETSI TS 151 026 V13.0.0 (2016-01)
4.1 Radio frequency bands
A repeater, as having a bi-directional amplifier capability, 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 are the MS and BTS transmit bands as defined in 3GPP
TS 45.005 [13], clause 2. A repeater is designed to operate in one or several pass bands within the MS and BTS transmit
bands as defined in 3GPP TS 45.005 [13], clause 2. In this document, such MS and BTS relevant bands are herein
referred as the repeater operating bands, as defined in clause 3.1. Repeater operating band(s) and repeater pass band(s)
are part of clause 4.3 Manufacturers declarations.
Table 1: void
NOTE: In some circumstances, for instance when an operator (or more than one operator who co-ordinate the use
of repeaters), is not allocated a complete band, it may be necessary to restrict the frequency range of
operations of repeaters. In these circumstances, the test of "Gain outside pass band" in annex A may be
used to verify the performance of the repeater.
4.2 Test environments
For each test in the present document, the environmental conditions under which the repeater is to be tested are defined.
4.2.1 Normal test environment
When a normal test environment is specified for a test, the test should be performed under any combination of
conditions between the minimum and maximum limits stated in table 2.
Table 2: Limits of conditions for Normal Test Environment
Condition Minimum Maximum
Barometric pressure 86 kPa 106 kPa
Temperature 15ºC 30ºC
Relative Humidity 20 % 85 %
Power supply Nominal, as declared by the manufacturer
Vibration Negligible
The ranges of barometric pressure, temperature and humidity represent the maximum variation expected in the
uncontrolled environment of a test laboratory. If it is not possible to maintain these parameters within the specified
limits, the actual values shall be recorded in the test report.
NOTE: This may, for instance, be the case for measurements of radiated emissions performed on an open field
test site.
