GPRS
(General Packet Radio Services)
Overview
.
G
PRS is a new non-voice value added services that allows
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 GPRS 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 signalling, 4 physical channels for Circuit
switched
and 3 physical channels for Packet switched

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.
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.
Any
deactivated SIM, due to wrong PIN entry, can be re-activated by the network operator only.

card is inserted.
Please check with the operator(s) in your country for detail information.
