Chapter 24: GPRS



General packet radio service (GPRS) is a packet oriented mobile data service on the 2G and 3G cellular communication system's global system for mobile communications (GSM). GPRS was originally standardized by European Telecommunications Standards Institute (ETSI) in response to the earlier CDPD and i-mode packet-switched cellular technologies. It is now maintained by the 3rd Generation Partnership Project (3GPP).



In theory, GPRS packet-based services cost users less than circuit-switched services since communication channels are being used on a shared-use, as-packets-are-needed basis rather than dedicated to only one user at a time. It is also easier to make applications available to mobile users because the faster data rate means that middleware currently needed to adapt applications to the slower speed of wireless systems are no longer be needed. As GPRS has become more widely available, along with other 2.5G and 3G services, mobile users of virtual private networks (VPNs) have been able to access the private network continuously over wireless rather than through a rooted dial-up connection.

Advantages:
 -We can enable internet when it is required.
-Internet is access even in remote areas.
-We can down load games, ring tones, images by visiting different web sites.
- Internet application you can enables easily.
- It can connect to laptop or desktop.
- You can enjoy wireless internet connection.
-GPRS has high speed than GSM network.
 -It is flexibility to work internet on your computer.
- Receives the data by sending when user required.
 -GPRS can be work in large distance or remote area.
 -GPRS is the quick and easy to implement.
Disadvantages:
 -The monthly contract cost is high.
 -It is more expensive than sms.
 -It varies between providers and countries.






HSCSD (High Speed Circuit Switched Data) enables data to be transferred more rapidly than the standard GSM (Circuit Switched Data) system by using multiple channels. The maximum number of timeslots that can be used is four, giving a maximum data transfer rate of 57.6 kbps (or 38.4 kbps on a GSM 900 network). HSCSD is more expensive to use than GPRS, because all four slots are used simultaneously - it does not transmit data in packets. Because of this, HSCSD is not as popular as GPRS and is being replaced by EDGE.

EDGE (Enhanced Data rates for GSM Evolution) or EGPRS provides data transfer rates significantly faster than GPRS or HSCSD. EDGE increases the speed of each timeslot to 48 kbps and allows the use of up to 8 timeslots, giving a maximum data transfer rate of 384 kbps. In places where an EDGE network is not available, GPRS will automatically be used instead. EDGE offers the best that can be achieved with a 2.5G network, and will eventually be replaced by 3G.

  1. GPRS is a cellular networking service that supports WAP, SMS text messaging, and other data communications. GPRS technology is integrated into so-called 2.5G mobile phones designed to provide faster data transfer speeds than older 2G cellular networks. nice workS~!

  2. it is true that GPRS packet-based services cost users less than circuit-switched services since communication channels are being used on a shared-use, as-packets-are-needed basis rather than dedicated to only one user at a time....keep it up sir :D

  3. A GPRS has become more widely available, along with other 2.5G and 3G services, and GPRS usage is typically charged based on volume of data.

  4. In other words,general Packet Radio Service (GPRS) is a new bearer service for GSM that greatly improves and simplifies wireless access to packet data networks GPRS applies packet radio principal to transfer user data packets in an efficient way b/w MS & external packet data network.

  7. Can you compare GPRS and EDGE

    1. EDGE is a digital mobile phone technology but GPRS is a mobile data service. and EDGE allows existing TDMA and GSM carriers to provide 3G services whereas GPRS allows both 2G and 3G communication systems only.

  8. As we all observe nowadays, GPRS are widely used in commercial things like laptops and mobile phones in order to download and get information without hassle..Although GPRS has its disadvantages..
