GSM overview

Preface

This page discusses the GSM mobile telephony system, which is increasingly

popular and established throughout the world. The term GSM usually means

the GSM standard and protocols in the frequency spectrum around 900MHz.

There is also DCS1800 - GSM protocols but at different air frequencies around

1800 MHz - and in the United States, where spectrum for Personal

Communication Services (PCS) was auctioned at around 1900MHz, operators

using the aptly-named GSM1900 are competing against a plethora of other

standards. As a result of this, the original and most widely-used GSM

frequency implementation is also becoming known as GSM900, and DCS1800

is also known as GSM1800. However, although the physical frequencies used

differ, the protocols and architecture remain the same.

System architecture

Figure 4 below shows the GSM system architecture, which consists of the

switching system, the base station system and the user equipment.

GSM, Basic Cellular System

3 Cell repeat pattern

Only possible in GSM due to

higher cross channel interference

tolerances

GSM, Basic Cellular System

MSC

BSC

BTS

BTS BTS

BTS

PSTN

Area divided up into Cells each with its own Base Transceiver station

(BTS) which operates on its own set of frequencies

The BTS are controlled by their own BSC (Base station controller) which

can control multiple BTS

The BSCis connected to the MSC (usually by land line) so the digital over

air connection is from the Mobile to the BTS, the link from the BTS to the

BSC can also be by land line.

MSC : Mobile Switching Centre acts as the interface to the PSTN.

3 cell repeat: possible in GSM due to higher tolerance to

cross channel interference. digital timing specs etc.

Other patterns apply,
