Foreword
This European Telecommunication Standard (ETS) has been produced by the Special Mobile Group
(SMG) of the European Telecommunications Standards Institute (ETSI).
This ETS defines the requirements for the transceiver of the digital mobile cellular and personal
communication systems operating in the 900 MHz (P-GSM, E-GSM and R-GSM) and 1 800 MHz band
(GSM 900 and DCS 1 800).
The contents of this ETS is subject to continuing work within SMG and may change following formal SMG
approval. Should SMG modify the contents of this ETS, it will be resubmitted for OAP by ETSI with an
identifying change of release date and an increase in version number as follows:
Version 5.x.y
where:
y the third digit is incremented when editorial only changes have been incorporated in the
specification;
x the second digit is incremented for all other types of changes, i.e. technical enhancements,
corrections, updates, etc.
The specification from which this ETS has been derived was originally based on CEPT documentation,
hence the presentation of this ETS may not be entirely in accordance with the ETSI rules.

1 Scope
This European Telecommunication Standard (ETS) defines the requirements for the transceiver of the
pan-European digital mobile cellular and personal communication systems operating in the 900 MHz and
1 800 MHz band (GSM 900 and DCS 1 800).
Requirements are defined for two categories of parameters:
- Those that are required to provide compatibility between the radio channels, connected either to
separate or common antennas, that are used in the system. This category also includes parameters
providing compatibility with existing systems in the same or adjacent frequency bands.
- Those that define the transmission quality of the system.
This ETS defines RF characteristics for the Mobile Station (MS) and Base Station System (BSS). The
BSS will contain either Base Transceiver Stations (BTS) or microcell base transceiver stations
(micro-BTS). The precise measurement methods are specified in GSM 11.10 and GSM 11.20.
Unless otherwise stated, the requirements defined in this ETS apply to the full range of environmental
conditions specified for the equipment (see annex D).
In this ETS some relaxations are introduced for GSM 900 MSs which fulfil the following conditions:
- pertain to power class 4 or 5 (see subclause 4.1.1);
- not designed to be vehicle mounted (see GSM 02.06).
In this ETS these Mobile Stations are referred to as "small MS".
NOTE: In this ETS, a handheld which can be connected to a car kit is not considered to be
vehicle mounted.
MSs may operate on more than one of the frequency bands specified in clause 2. These MSs, defined in
GSM 02.06, are referred to as "Multi band MSs" in this ETS. Multi band MSs shall meet all requirements
for each of the bands supported. The relaxation on GSM 900 for a "small MS" are also valid for a multi
band MS if it complies with the definition of a small MS.
The RF characteristics of repeaters are defined in annex E of this ETS. Annexes D and E are the only
clauses of this ETS applicable to repeaters. Annex E does not apply to the MS or BSS.

Operators may implement networks which operates on a combination of the frequency bands above to
support multi band mobile terminals which are defined in GSM 02.06.
The carrier spacing is 200 kHz.
The carrier frequency is designated by the absolute radio frequency channel number (ARFCN). If we call
Fl(n) the frequency value of the carrier ARFCN n in the lower band, and Fu(n) the corresponding
frequency value in the upper band, we have:
P-GSM 900 Fl(n) = 890 + 0.2*n 1 £ n £ 124 Fu(n) = Fl(n) + 45
E-GSM 900 Fl(n) = 890 + 0.2*n Fu(n) = Fl(n) + 45
0 £ n £ 124
Fl(n) = 890 + 0.2*(n-1024) 975 £ n £ 1 023
DCS 1 800 Fl(n) = 1710.2 + 0.2*(n-512) Fu(n) = Fl(n) + 95
512 £ n £ 885
Frequencies are in MHz.

3 Reference configuration
The reference configuration for the radio subsystem is described in GSM 05.01.
The micro-BTS is different from a normal BTS in two ways. Firstly, the range requirements are much
reduced whilst the close proximity requirements are more stringent. Secondly, the micro-BTS is required
to be small and cheap to allow external street deployment in large numbers. Because of these differences
the micro-BTS needs a different set of RF parameters to be specified. Where the RF parameters are not
different for the micro-BTS the normal BTS parameters shall apply.
4 Transmitter characteristics
Throughout this clause, unless otherwise stated, requirements are given in terms of power levels at the
antenna connector of the equipment. For equipment with integral antenna only, a reference antenna with
0 dBi gain shall be assumed.
The term output power refers to the measure of the power when averaged over the useful part of the burst
(see annex B).
The term peak hold refers to a measurement where the maximum is taken over a sufficient time that the
level would not significantly increase if the holding time were longer.
4.1 Output power
4.1.1 Mobile Station
The MS maximum output power and lowest power control level shall be, according to its class, as defined
in the following table (see also GSM 02.06).
Power GSM 900 DCS 1 800 Tolerance (dB)
class Nominal Maximum Nominal Maximum for conditions
output output
power power normal extreme
1 - - - - - - 1 W (30 dBm) ±2 ±2.5
2 8 W (39 dBm) 0.25 W (24 dBm) ±2 ±2.5
3 5 W (37 dBm) 4 W (36 dBm) ±2 ±2.5
4 2 W (33 dBm) ±2 ±2.5
5 0.8 W (29 dBm) ±2 ±2.5
NOTE: The lowest nominal output power for all classes of GSM 900 MS is 5 dBm
and for all classes of DCS 1 800 MS is 0 dBm.
A multi band MS has a combination of the power class in each band of operation from the table above.
Any combination may be used.
The different power control levels needed for adaptive power control (see GSM 05.08) shall have the
nominal output power as defined in the table below, starting from the power control level for the lowest
nominal output power up to the power control level for the maximum nominal output power corresponding
to the class of the particular MS as defined in the table above. Whenever a power control level commands
the MS to use a nominal output power equal to or greater than the maximum nominal output power for the
power class of the MS, the nominal output power transmitted shall be the maximum nominal output power
for the MS class, and the tolerance of ±2 or 2.5 dB (see table above) shall apply.

NOTE 1: For DCS 1 800, the power control levels 29, 30 and 31 are only used "in call" for power
control purposes. These levels are not used when transmitting the parameter TX PWR
MAX CCH, for cross phase compatibility reasons. If levels greater than 30 dBm are
required from the MS during a random access attempt, then these shall be decoded
from parameters broadcast on the BCCH as described in GSM 05.08.
Page 12
ETS 300 910 (GSM 05.05 version 5.7.1): June 1998
Furthermore, the difference in output power actually transmitted by the MS between two power control
levels where the difference in nominal output power indicates an increase of 2 dB (taking into account the
restrictions due to power class), shall be +2 ± 1.5 dB. Similarly, if the difference in output power actually
transmitted by the MS between two power control levels where the difference in nominal output power
indicates an decrease of 2 dB (taking into account the restrictions due to power class), shall be
-2 ± 1.5 dB.
NOTE 2: A 2 dB nominal difference in output power can exist for non-adjacent power control
levels e.g. power control levels 18 and 22 for GSM 900; power control levels 31 and 0
for class 3 DCS 1 800 and power control levels 3 and 6 for class 4 GSM 900.
A change from any power control level to any power control level may be required by the base transmitter.
The maximum time to execute this change is specified in GSM 05.08.
4.1.2 Base station
The Base Station Transmitter maximum output power, measured at the input of the BSS Tx combiner,
shall be, according to its class, as defined in the following tables:
GSM 900 DCS 1 800
TRX Maximum TRX Maximum
power class output power power class output power
1 320 - (< 640) W 1 20 - (< 40) W
2 160 - (< 320) W 2 10 - (< 20) W
3 80 - (< 160) W 3 5 - (< 10) W
4 40 - (< 80) W 4 2.5 - (< 5) W
5 20 - (< 40) W
6 10 - (< 20) W
7 5 - (< 10) W
8 2.5 - (< 5) W
The micro-BTS maximum output power per carrier measured at the antenna connector after all stages of
combining shall be, according to its class, defined in the following table.
GSM 900 micro-BTS DCS 1 800 micro-BTS
TRX power Maximum output power TRX power Maximum output power
class class
M1 (> 19) - 24 dBm ((> 0.08) - 0.25 W) M1 (> 27) - 32 dBm ((> 0.5) - 1.6 W)
M2 M2 (> 22) - 27 dBm ((> 0.16) - 0.5 W)
(> 14) - 19 dBm ((> 0.03) - 0.08 W)
M3 (> 9) - 14 dBm ((> 0.01) - 0.03 W) M3 (> 17) - 22 dBm ((> 0.05) - 0.16 W)
The tolerance of the actual maximum output power of the BTS shall be ±2 dB under normal conditions
and ±2.5 dB under extreme conditions. Settings shall be provided to allow the output power to be reduced
from its maximum level in at least six steps of nominally 2 dB with an accuracy of ±1 dB to allow a fine
adjustment of the coverage by the network operator. In addition, the actual absolute output power at each
static RF power step (N) shall be 2*N dB below the absolute output power at static RF power step 0 with a
tolerance of ±3 dB under normal conditions and ±4 dB under extreme conditions. The static RF power
step 0 shall be the actual output power according to the TRX power class.
As an option the BSS can utilize downlink RF power control. In addition to the static RF power steps
described above, the BSS may then utilize up to 15 steps of power control levels with a step size of 2 dB
±1.5 dB, in addition the actual absolute output power at each power control level (N) shall be 2*N dB
below the absolute output power at power control level 0 with a tolerance of ±3 dB under normal
conditions and ±4 dB under extreme conditions. The power control level 0 shall be the set output power
according to the TRX power class and the six power settings defined above.
Network operators may also specify the BTS output power including any Tx combiner, according to their
needs.

ETS 300 910 (GSM 05.05 version 5.7.1): June 1998
4.2 Output RF spectrum
The specifications contained in this subclause apply to both BTS and MS, in frequency hopping as well as
in non frequency hopping mode, except that beyond 1800 kHz offset from the carrier the BTS is not tested
in frequency hopping mode.
Due to the bursty nature of the signal, the output RF spectrum results from two effects:
- the modulation process;
- the power ramping up and down (switching transients).
The two effects are specified separately; the measurement method used to analyse separately those two
effects is specified in GSM 11.10 and 11.20. It is based on the "ringing effect" during the transients, and is
a measurement in the time domain, at each point in frequency.
The limits specified thereunder are based on a 5-pole synchronously tuned measurement filter.
Unless otherwise stated, for the BTS, only one transmitter is active for the tests of this section.
4.2.1 Spectrum due to the modulation and wide band noise
The output RF modulation spectrum is specified in the following tables. A mask representation of this
specification is shown in annex A. This specification applies for all RF channels supported by the
equipment.
The specification applies to the entire of the relevant transmit band and up to 2 MHz either side.
The specification shall be met under the following measurement conditions:
- For BTS up to 1800 kHz from the carrier and for MS in all cases:
Zero frequency scan, filter bandwidth and video bandwidth of 30 kHz up to 1800 kHz from the
carrier and 100 kHz at 1800 kHz and above from the carrier, with averaging done over 50 % to
90 % of the useful part of the transmitted bursts, excluding the midamble, and then averaged over
at least 200 such burst measurements. Above 1800 kHz from the carrier only measurements
centred on 200 kHz multiples are taken with averaging over 50 bursts.
- For BTS at 1800 kHz and above from the carrier:
Swept measurement with filter and video bandwidth of 100 kHz, minimum sweep time of 75 ms,
averaging over 200 sweeps. All slots active, frequency hopping disabled.
- When tests are done in frequency hopping mode, the averaging shall include only bursts
transmitted when the hopping carrier corresponds to the nominal carrier of the measurement. The
specifications then apply to the measurement results for any of the hopping frequencies.
The figures in tables a) and b) below, at the vertically listed power level (dBm) and at the horizontally listed
frequency offset from the carrier (kHz), are then the maximum allowed level (dB) relative to a
measurement in 30 kHz on the carrier.
NOTE: This approach of specification has been chosen for convenience and speed of testing.
It does however require careful interpretation if there is a need to convert figures in the
following tables into spectral density values, in that only part of the power of the carrier
is used as the relative reference, and in addition different measurement bandwidths
are applied at different offsets from the carrier. Appropriate conversion factors for this
purpose are given in GSM 05.50.
For the BTS, the power level is the "actual absolute output power" defined in subclause 4.1.2. If the power
level falls between two of the values in the table, the requirement shall be determined by linear
interpolation.

The following exceptions shall apply, using the same measurement conditions as specified above;
i) In the combined range 600 kHz to 6 MHz above and below the carrier, in up to three bands of
200 kHz width centred on a frequency which is an integer multiple of 200 kHz, exceptions at up to
-36 dBm are allowed.
ii) Above 6 MHz offset from the carrier in up to 12 bands of 200 kHz width centred on a frequency
which is an integer multiple of 200 kHz, exceptions at up to -36 dBm are allowed. For the BTS only
one transmitter is active for this test.
Using the same measurement conditions as specified above, if a requirement in tables a) and b) is tighter

Those effects are also measured in the time domain and the specifications assume the following
measurement conditions: zero frequency scan, filter bandwidth 30 kHz, peak hold, and video bandwidth
100 kHz.

a) Mobile Station:
Power level Maximum level measured

39 dBm -21 dBm -26 dBm -32 dBm -36 dBm
-23 dBm -26 dBm -32 dBm -36 dBm£ 37 dBm
NOTE 1: The relaxations for power level 39 dBm is in line with the modulated spectra and thus
causes negligible additional interference to an analogue system by a GSM signal.
NOTE 2: The near-far dynamics with this specification has been estimated to be approximately
58 dB for MS operating at a power level of 8 W or 49 dB for MS operating at a power
level of 1 W. The near-far dynamics then gradually decreases by 2 dB per power level
down to 32 dB for MS operating in cells with a maximum allowed output power of
20 mW or 29 dB for MS operating at 10 mW.
NOTE 3: The possible performance degradation due to switching transient leaking into the
beginning or the end of a burst, was estimated and found to be acceptable with respect
to the BER due to cochannel interference (C/I).
b) Base transceiver station:
The maximum level measured, after any filters and combiners, at the indicated offset from the carrier, is:
Maximum level measured
400 kHz 600 kHz 1 200 kHz 1 800 kHz
GSM 900 -57 dBc -67 dBc -74 dBc -74 dBc
DCS 1 800 -50 dBc -58 dBc -66 dBc -66 dBc
or -36 dBm, whichever is the higher.
dBc means relative to the output power at the BTS, measured at the same point and in a filter bandwidth
of at least 300 kHz.
NOTE 4: Some of the above requirements are different from those specified in subclause 4.3.2.
4.3 Spurious emissions
The limits specified thereunder are based on a 5-pole synchronously tuned measurement filter.
4.3.1 Principle of the specification
In this section, the spurious transmissions (whether modulated or unmodulated) and the switching
transients are specified together by measuring the peak power in a given bandwidth at various
frequencies. The bandwidth is increased as the frequency offset between the measurement frequency
and, either the carrier, or the edge of the MS or BTS transmit band, increases. The effect for spurious
signals of widening the measurement bandwidth is to reduce the allowed total spurious energy per MHz.
The effect for switching transients is to effectively reduce the allowed level of the switching transients (the
peak level of a switching transient increases by 6 dB for each doubling of the measurement bandwidth).
The conditions are specified in the following table, a peak-hold measurement being assumed.
The measurement conditions for radiated and conducted spurious are specified separately in GSM 11.10
and 11.2x series. The frequency bands where these are actually measured may differ from one type to the
other (see GSM 11.10 and 11.2x series).

The measurement settings assumed correspond, for the resolution bandwidth to the value of the
measurement bandwidth in the table, and for the video bandwidth to approximately three times this value.
NOTE: For radiated spurious emissions for MS with antenna connectors, and for all spurious
emissions for MS with integral antennas, the specifications currently only apply to the
frequency band 30 MHz to 4 GHz. The specification and method of measurement
outside this band are under consideration.
4.3.2 Base Transceiver Station
The power measured in the conditions specified in subclause 4.3.1a shall be no more than -36 dBm.
The power measured in the conditions specified in subclause 4.3.1b shall be no more than:
- 250 nW (-36 dBm) in the frequency band 9 kHz - 1 GHz;
- 1 μW (-30 dBm) in the frequency band 1 - 12.75 GHz.
NOTE 1: For radiated spurious emissions for BTS, the specifications currently only apply to the
frequency band 30 MHz to 4 GHz. The specification and method of measurement
outside this band are under consideration.
Page 19
ETS 300 910 (GSM 05.05 version 5.7.1): June 1998
In the BTS receive band, the power measured using the conditions specified in 4.2.1, with a filter and
video bandwidth of 100 kHz shall be no more than:
GSM (dBm) DCS (dBm)
Normal BTS -98 -98
Micro BTS M1 -91 -96
Micro BTS M2 -86 -91
Micro BTS M3 -81 -86
R-GSM 900 BTS -89
These values assume a 30 dB coupling loss between transmitter and receiver. If BTSs of different classes
are co-sited, the coupling loss must be increased by the difference between the corresponding values
from the table above.
Measures must be taken for mutual protection of receivers when GSM 900 and DCS 1 800 BTS are
co-sited.
NOTE 2: Thus, for this case, assuming the coupling losses are as above, then the power
measured in the conditions specified in subclause 4.2.1, with a filter and video
bandwidth of 100 kHz should be no more than the values in the table above for the
GSM 900 transmitter in the band 1 710 - 1 785 MHz and for DCS 1 800 transmitter in
the band 876 - 915 MHz.
In any case, the powers measured in the conditions specified in subclause 4.2.1, with a filter and video
bandwidth of 100 kHz shall be no more than -47 dBm for the GSM BTS in the band 1 805 - 1 880 MHz
and -57 dBm for a DCS 1 800 BTS in the band 921 - 960 MHz.
4.3.3 Mobile Station
The power measured in the conditions specified in subclause 4.3.1a, for a MS when allocated a channel,
shall be no more than -36 dBm. For R-GSM 900 MS except small MS the corresponding limit shall be
-42 dBm.
The power measured in the conditions specified in subclause 4.3.1b for a MS, when allocated a channel,
shall be no more than (see also note in subclause 4.3.1b above):
- 250 nW (-36 dBm) in the frequency band 9 kHz - 1 GHz;
- 1 μW (-30 dBm) in the frequency band 1 - 12.75 GHz.
The power measured in a 100 kHz bandwidth for a mobile, when not allocated a channel (idle mode), shall
be no more than (see also note in 4.3.1 above):
- 2 nW (-57 dBm) in the frequency bands 9 kHz - 880 MHz, 915 - 1 000 MHz;
- 1.25 nW (-59 dBm) in the frequency band 880 - 915 MHz;
- 5 nW (-53 dBm) in the frequency band 1.71 - 1.785 GHz;
- 20 nW (-47 dBm) in the frequency bands 1 - 1.71 GHz, 1.785 - 12.75 GHz.
NOTE: The idle mode spurious emissions in the receive band are covered by the case for MS
allocated a channel (see below).
When allocated a channel, the power emitted by the MS, when measured using the measurement
conditions specified in 4.2.1, but with averaging over at least 50 burst measurements, with a filter and
video bandwidth of 100 kHz, for measurements centred on 200 kHz multiples, in the band 935 - 960 MHz
shall be no more than -79 dBm, in the band 925-935 MHz shall be no more than -67 dBm and in the band
1 805 - 1 880 MHz, shall be no more than -71 dBm. For R-GSM 900 mobiles, in addition, a limit of
-60 dBm shall apply in the frequency band 921 - 925 MHz.
As exceptions up to five measurements with a level up to -36 dBm are permitted in each of the bands
925 - 960 MHz and 1 805 - 1 880 MHz for each ARFCN used in the measurements.

When hopping, this applies to each set of measurements, grouped by the hopping frequencies as
described in subclause 4.2.1.
4.4 Radio frequency tolerance
The radio frequency tolerance for the base transceiver station and the MS is defined in GSM 05.10.
4.5 Output level dynamic operation
NOTE: The term "any transmit band channel" is used here to mean:
any RF channel of 200 kHz bandwidth centred on a multiple of 200 kHz which is within
the relevant transmit band.
4.5.1 Base Transceiver Station
The BTS shall be capable of not transmitting a burst in a time slot not used by a logical channel or where
DTX applies. The output power relative to time when sending a burst is shown in annex B. In the case
where the bursts in two (or several) consecutive time slots are actually transmitted, at the same
frequency, no requirements are specified to the power ramping in the guard times between the active time
slots, and the template of annex B shall be respected at the beginning and the end of the series of
consecutive bursts. The residual output power, if a timeslot is not activated, shall be maintained at, or
below, a level
