Technology

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.

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.
