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.).
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.
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 (
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
.
), is built in. The PIN is stored in the card and can be changed
GPRS is a new non-voice value added services that a llows information to be sent and
received across a GSM mobile telephone network. It supplements today’s Circuit Switched
Data (CSD) and Short Message Services (SMS). GPRS involves overlaying a packet based
air interface on the existing circuit switched GSM network. This gives the option to use a
packet-based data service. The information is split into separated but related “packets” before
being transmitted and reassembled at the receiving end. Theoretically, maximum speeds of
up to 171.2 kilobits per second (kbps) are achievable with GPR S using all eight timeslots at
the same time. This is about 3 times as fast as the data transmission speed possible over
today’s fixed telecommunications networks and 10 times as fast as current Circuit Switched
Data services on GSM networks
.
Example: Cell with 1 Frequency channel:
1 physical channel for signaling, 4 physical channels for Circuit switched and 3 physical
channels
for Packet switched.
The CF62 Leopard is designed as a clamshell with non-exchangeable housing. The lift
cover,base lower and battery cover are lacquered parts (1shot-molding;1color). Base
upper assembly is composed of base upper and light loop by ultra-sonic welding (The
base upper is lacquered 1shot-molding part.The light loop is a 2shot-molding part by light
loop and galvanized ribs).

4.2 Interface CF62 Leopard to accessories
There are no specific mechanical interfaces to the car cradle. The car cradle is
designed to fit the existing design. The I/O-Connector (Lumberg-slim-connector) is
in use. The compatible interface is suitable to use the travel charger.
