1 Cellular Communication
1.1 Coverage Concept
T
he cellular systems is made up of numerous transmitting and receiving sites, whose
individual coverage areas partially overlap. The concept of frequency re-use, same
frequency is used by several sites, allows a high traffic density in a wide area. Due
to the limited transmission range of the terminals, cellular systems are based on a
large number of base stations on the infrastructure side, scattered over the area to cover,
with each covering a fairly small geographical zone called cell. Cells are often
represented by hexagons (see figure 1.1.).

1.2 GSM Network Architecture
GSM network can be broadly divided into three broad parts, namely:
1. Mobile Station(MS) carried by the subscriber
2. Base Station Sub-system(BSS) which controls the radio link with the mobile station.
3. Mobile Switching Center(MSC) which performs the switching of calls between the
mobile users, and between mobile and fixed network users.
FIGURE 1.2
GSM ARCHITECTURE
Each mobile station is given a unique identity. As soon as the mobile phone is turned on,
it registers with the network and is authenticated, as such the network could always find
the mobile phone. Larger amount of data is being exchanged to and from the following
functional blocks in the MSC:
Visitor Location Register, VLR
Contain relevant data of all mobiles located in the serving MSC, but not belong to the
area.
Home Location Register, HLR
Stores identity and user data of all the mobile users belonging to the area.
Authentication Center, AUC
Provides the HLR with different sets of parameters to complete the authentication of the
mobile station.
Equipment Identity Register, EIR
An option the network operator can use to enforce security. With this feature the network
can identify defective or stolen mobile that may not be used in the network.

1.3 Subscriber Identity Module (SIM)
SIM is a smart card which has a computer and memory chip that is permanently installed
in the mobile equipment. It comes in either the size of a credit card or smaller version
known as the plug-in SIM.
SIM card using 5V technology is not supported.
The subscriber information, which includes a unique number called the International
Mobile Subscriber Identity (IMSI) is stored in the SIM card. SIM card identifies the
subscriber to the network.
To protect the SIM card from improper use, a security feature, a four digits personal
identification number (PIN), is built in. The PIN is stored in the card and can be changed
by the subscriber.
PIN2
Is required for additional functions available with a special SIM
card (Consult the operator for more Information about the
PIN 2).
A code (PUK) is provided for unlocking the SIM card if the SIM card is blocked
.
