1 Scope
The present document defines the requirements for the transceiver of the pan-European digital cellular
telecommunications systems GSM.
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.
The present document 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 11.21.
Unless otherwise stated, the requirements defined in the present document apply to the full range of environmental
conditions specified for the equipment (see annex D).
The requirements for a MS in a mixed-mode system, MXM 850 and MXM 1900, corresponds to the requirements for
GSM 850 MS and PCS 1900 MS respectively.
In the present document some relaxation's are introduced for GSM 400 MSs, GSM 900 MSs and GSM 850 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);
- for mobile stations supporting 8-PSK, pertaining to power class E2 or E3.
In the present document these Mobile Stations are referred to as "small MS". For other mobile stations supporting 8-
PSK and pertaining to power class E2 or E3 the term "small MS" is applicable for receiver performance requirements
only (see clause 6).
NOTE: In the present document, 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 the present document. Multi band MSs shall meet all requirements for each of the
bands supported. The relaxation on GSM 400 MSs, GSM 900 MSs and GSM 850 MSs 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 the present document. Annexes D and E are the only
clauses of the present document applicable to repeaters. Annex E does not apply to the MS or BSS.

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.
The pico-BTS is an extension of the micro-BTS concept to the indoor environments. The very low delay spread, low
speed, and small cell sizes give rise to a need for a different set of RF parameters to be specified.
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.
For GMSK modulation, the term output power refers to the measure of the power when averaged over the useful part of
the burst (see annex B).
ETSI
(GSM 05.05 version 8.3.1 Release 1999) 11 ETSI EN 300 910 V8.3.1 (2000-09)
For 8-PSK modulation, the term output power refers to a measure that, with sufficient accuracy, is equivalent to the
long term average of the power when taken over the useful part of the burst for random data.
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 tables (see also GSM 02.06).

NOTE: The lowest nominal output power for all classes of GSM 400 and GSM 900 MS is 5 dBm and for all classes of
DCS 1 800 and PCS 1900 MS is 0 dBm.
Maximum output power for 8-PSK in any one band is always equal to or less than GMSK maximum output power for
thesameequipmentinthesameband.
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 PCS 1 900, including its actual antenna gain, shall not exceed a maximum of 2 Watts (+33 dBm) EIRP per the
applicable FCC rules for wideband PCS services [ANSI T1.610, "Generic Procedures for Supplementary Services",
1990]. Power Class 3 is restricted to transportable or vehicular mounted units.
For GSM 850 MS, including its actual antenna gain, shall not exceed a maximum of 7 Watts (+38,5 dBm) ERP per the
applicable FCC rules for public mobile services. [FCC Part 22, Subpart H, Section 22.913]
ETSI
(GSM 05.05 version 8.3.1 Release 1999) 12 ETSI EN 300 910 V8.3.1 (2000-09)
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

NOTE 1: For DCS 1 800, the power control levels 29, 30 and 31 are not used when transmitting the parameter
MS_TXPWR_MAX_CCH on BCCH, 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.

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 400 and 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 400 and 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.

NOTE: Tolerance for MS Power Classes 1 and 2 is ± 2 dB normal
and ± 2,5 dB extreme at Power Control Levels 0 and 3
respectively.
The output power actually transmitted by the MS at each of the power control levels shall form a monotonic sequence,
and the interval between power steps shall be 2 dB ±1.5 dB except for the step between power control levels 30 and 31
where the interval is 1 dB ±1dB.
The MS transmitter may be commanded by the BTS to change from any power control level to any other power control
level. The maximum time to execute this change is specified in GSM 05.08.
For CTS transmission, the nominal maximum output power of the MS shall be restricted to:
- 11 dBm (0.015 W) in GSM 900 i.e. power control level 16;
- 12 dBm (0.016 W) in DCS 1 800 i.e. power control level 9.
