3. Introduction
Think for a moment what would life be like if you had to live in the 15th century? How would you go from one city to another? Will you find an airplane? Or would you go by train? Or you would walk or ride a camel or a horse? How are you going to send a message? Texting? Sending an ? Using SMS or MMS?

4. History
Since 1999 the GPRS was one of the first technologies that brought wireless Internet to cell.
The service started to become available in 2001.
GPRS uses packet switching to handle data efficiently.
The service breaks the data into small bursts.
Add more information into a given amount of bandwidth.
Users only pay for the bursts instead of a steady stream.
Data transmission speed ran around 28 kilobytes per second, but GPRS phones could surf the web at 60 kilobytes per second.

5. Why GPRS Is important? Allows data transmission speeds up to 100 Kbps
A packet based
Supports the world’s most important Internet communications protocols.
Operate at a much higher speed than current networks should provide a huge advantage.
Provides a seamless and instant connection from a mobile PC to the Internet allowing all existing Internet applications such as web browsing and .

7. cost Charged on exactly how much data is being sent and received.
Users of non-GPRS can be charged even if their phone is in an idle state
GPRS will only be charged if data is actually being transferred.

8. Class A Class B Class C Categories
Sends and receive data at the same time and also have a GPRS and GSM modes active simultaneously.
Class B
Send and receive data and voice simultaneously. Attached to GPRS and GSM modes services that may be used only one service at a time.
Class C
Can only have either GPRS or GSM mode active at one per time, which the user needs to switch manually between them.

9. Advantages Constant connection to the Internet.
Mobility, provide the user wireless access to the Internet.
Simultaneous use, allows the user to send or receive voice calls at the same time when they’re browsing the Internet.
Speed, transfer data from 9.6 kilobytes per second up to 114 kilobytes per second.
Cost, allows the user to send longer messages for cheaper chargers

10. Disadvantages Speed, GPRS technology has its limitation.
Reliability, happens when a lot of people talk on their cellphones in the same area and at the same time
Distance factors, happens according to the distance factor involves in the GPRS technology.

11. GPRS VS. GSM GPRS GSM speed of a wireless connection
process the same AT commands with higher amount of messages
process more than 30 messages per minute
GSM
speed of a dialup connection
programmed to support the standard set of AT commands
process around 6 or 10 messages per minute

12. GPRS VS. EDGE GPRS EDGE 2G High speed mobile data service 2.5G
permits both of 2G and 3G communication system
EDGE
2.5G
Higher speed
digital mobile phone technology
permits both TDMA and GSM carries

13. Network Protocol used
(SNDCP), offers different functions such as segmentation, compression and multiplexing.
(BSSGP), process routing and quality of service information for the base station system.
(LLC), responsible for assuring the reliable transfer of any user data through wireless network.
(GMM), operates in the signaling plane of GPRS and able to handle mobility problems.
(GTP), responsible for tunneling the protocol data units across the IP backbone through adding routing information
Network Service, responsible of managing the convergence sub-layer.
(BSSAP+), responsible of managing paging for data and voice connections and that optimizes paging for the mobile subscribers.

14. security
The SGSN complete chipper and authentication setting procedures according to the same keys, criteria and algorithms that exist in GSM. The GPRS use a chippering algorithm optimized for the packet data transmission.

15. The Network SGSN GGSN Transfers packets to mobile station (MSs).
Can notice a new GPRS MSs.
Able to complete the mobility management tasks.
Linked to the base station subsystem through the Frame Relay linking to the PCU in the BSC.
SGSN
Used like an interface to the external IP networks.
Keeps the routing information.
Has address mapping and network and subscriber screening.
A single or multiple GGSNs can be used to support many SGSNs.
GGSN

16. conclusion
“The science of today is the technology of tomorrow.” (Technology quotes, 2012). Who could imagine that one day we could browse the Internet, send s and do different things with our own mobiles, through only a press of button?
