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 11.2x series.
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 mobile stations 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 standard, a handheld which can be connected to a car kit is not considered to be vehicle mounted.
Mobile stations may operate on more than one of the frequency bands specified in clause 2. These mobile stations, defined in GSM 02.06, are referred to as "Multi band mobile stations" in this standard. Multi band mobile stations 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.
