The present document defines the requirements for the transceiver of the panEuropean 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 (microBTS). 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 mixedmode 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 clause 4.1.1);
not designed to be vehicle mounted (see GSM 02.06).
In the present document these Mobile Stations are referred to as "small MS".
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
