GPRS
BACKGROUND
AND
EVOLUTION
GPRS BACK GROUND
• With Mobile penetration reaching its full potential, GPRS gives
Mobile operators competitive edge and optimum use of the
infrastructure.
•SMS is a good example of just how hungry users are for data
services.
• The main Objective of GPRS is to offer the access to standard
data networks, using protocols e.g. TCP/IP and X.25
• Transactions such as Credit Card checks and a variety of
telemetric applications benefit from the fast session set-ups.
• GPRS enables efficient use of radio resources by allowing many
data users to share the same interface on a statistical basis.
•The main benefits of GPRS are that it reserves radio resources
only when there is data to be sent
• Mobile users doesn’t have to connect to the network each time he
wants to transfer the data, he can stay connected all day.
