Introduction
The present document is adding the requirements for the 2 Watt professional small mobile stations (OPH and OPS) for
the pan-European digital cellular telecommunication system R-GSM/ER-GSM. The requirements already defined in the
previous version 1.3.1 for the receiver of professional mobile station 8 Watt (cab radio and EDOR) are kept unchanged.

1 Scope
The present document defines the Radio Frequency requirements specific for the professional Mobile Station. The
measurement methods are specified in ETSI TS 102 933-2 [5] and ETSI TS 100 607-1 [2].
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 reception requirements for all types of professional MS.
MSs may operate on more than one of the frequency bands specified in clause 4. These MSs, defined in
ETSI EN 300 919 [1], are referred to as "Multi band MSs" in the present document.

4 Frequency bands and channel arrangement
a) Railways GSM 900 Band, R-GSM (includes Standard and Extended GSM 900 Band):
- for Railways GSM 900 band, the system is required to operate in the following frequency band:
876 MHz to 915 MHz: mobile transmit, base receive;
921 MHz to 960 MHz: base transmit, mobile receive.
b) Extended Railways GSM 900 Band, ER-GSM (includes Standard and Extended GSM 900 Band):
- for Railways GSM 900 band, the system is required to operate in the following frequency band:
873 MHz to 915 MHz: mobile transmit, base receive;
918 MHz to 960 MHz: base transmit, mobile receive.
NOTE 1: The term GSM 900 is used for any GSM system, which operates in any 900 MHz band.
NOTE 2: The BTS may cover a complete band, or the BTS capabilities may be restricted to a subset only,
depending on the operators needs.
The carrier spacing is 200 kHz.
The carrier frequency is designated by the absolute radio frequency channel number (ARFCN). For each carrier
ARFCN, the corresponding frequency value in the lower band (Fl(n)) and in the upper band (Fu(n) are defined below.

ARFCN in the lower band number (ARFCN) carrier ARFCN in the
upper band

5 Transmitter characteristics for 8 Watt mobiles
5.0 General provisions
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.
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.
Unless otherwise specified, the common rules of ETSI TS 100 607-1 [2] shall be applied.
5.1 Output power
5.1.1 Mobile Station
The MS maximum output power and lowest power control level shall be, according to its class (as specified in
ETSI EN 300 919 [1]), as defined in tables 1 and 2 .
For GMSK modulation:
Table 1
ER-GSM/R-GSM Tolerance (dB)
Power class
Nominal Maximum output for conditions
Power Normal Extreme
2 8 W (39 dBm) ±2 ±2,5

For 8-PSK modulation (optional):
Table 2
ER-GSM/R-GSM ER-GSM/R-GSM
Power class
Nominal Maximum output Tolerance (dB) for conditions
Power Normal Extreme
E1 33 dBm ±2 ±2,5

Maximum output power for 8-PSK in any one band is always equal to or less than GMSK maximum output power for
the same equipment in the same band.
The different power control levels as defined in ETSI TS 100 911 [7] needed for adaptive power control shall have the
nominal output power as defined
