GPRS Full Form
|GPRS Full Form is||General Packet Radio Service|
Definition of GPRS
General Packet Radio Service is a type of packet-switching technology that enables data transfers to mobile communications (GSM) via the cellular network’s global system while providing end-to-end, also wide-area wireless IP connectivity.
GPRS transmission rate can be improved from 56Kbps to 114Kbps also. At the same time, there is no need for existing wireless applications in the form of an intermediary converter, due to this connection and transmission become more convenient and easy. In this way, users can easily log on to the Internet, while they can also participate in interactive communication such as video conferences, and users can connect to the same video network (VRN) without having to connect to the network. Dial-up only.
GPRS Who owns it?
GPRS specifications are written by the European Telecommunications Standard Institute (ETSI), a European counterpart of the American National Standard Institute (ANSI). So we can consider it as the owner of GPRS.
GPRS Key Features
Let us now know which are the three key features of GPRS which describe the wireless packet data:
1. always-online feature – This eliminates the dial-up process, which makes applications just one click away.
2. This is an upgrade with Mehjuda Systems – Operators do not have to replace their equipment; Rather, GPRS is an added feature on top of their existing infrastructure.
- having open architecture
- Providing Consistent IP Services
- The same infrastructure that too for different air interfaces
- Integrated telephony and Internet infrastructure
- Leveraging industry investment that too in IP
- Its service innovation is completely independent of infrastructure
What services are offered in GPRS?
Now let us know about the services provided by GPRS.
1. SMS messaging and broadcasting
2. Push-to-talk over cellular
3. Instant messaging and presence
4. Multimedia messaging service
5. Point-to-Point and Point-to-Multipoint services
What are the protocols supported by GPRS?
What are the protocols that GPRS supports
1. Internet Protocol (IP)
2. Point-To-Point Protocol (PPP)
What are the advantages of
GPRS technology provides many benefits and advantages to the users and network operators as compared to the basic GSM system. It used to be widely deployed via cellular telecommunications technology to provide a realistic data capability. Now let us know what are the advantages of GPRS:-
Higher Data Rate
GPRS provides higher data rates in shorter access times. GPRS offers a transfer rate of up to 115kbit/s (with a maximum of 171.2kbit/s, excluding FEC). This means that GPRS and ISDN users can easily surf the Internet through portable computers.
Low Connection Cost
In the GSM network, there is high resource utilization. Whereas GPRS introduced packet-switching, transmission mode for the first time, so that in true sense circuit-switching GSM data transmission mode was used, while it was much more important for wireless resource scarcity.
Now for the billing of GPRS users, the data volume of communication is done on the main basis, so that it is easily known that how much the user has to pay for using the service. Now even though the connection time of GPRS users may not be a few hours, but they have to pay only a relatively low connection cost.
Short Access Times
GPRS mainly provides a connection to mobile users and remote data networks, so that mobile users can be provided with high-speed wireless IP and wireless X.25 services.
GPRS packet transmission offers a more user-friendly billing that too as compared to the billing of circuit-switched services. Talking about circuit switched services, then billing is based on the duration of the connection. It is not suitable for applications that have bursty traffic. In this the user has to pay the entire airtime, that too during idle periods when no packets are sent (e.g., when a user reads a web page).
Conversely, in packet switched services, billing is based on the result of the transmitted data. The user’s advantage in this is that even though they are “online” for a long time, they are billed on the basis of the transmitted data volume.
A very big advantage is GPRS technology in that it offers a higher data rate than too compared to GSM. Rates up to 172 kbps are possible, while maximum data rates can be realistically achieved under most conditions in which the range is 15 – 40 kbps.
Packet switched operation:
Where circuit switched techniques were used in GSM, GPRS technology uses packet switching in line that too with the Internet. This makes more efficient use of available capacity, and at the same time it allows greater commonality that too Internet techniques
Always on connectivity:
Another advantage of GPRS is that it offers “Always On” capability. When circuit switched techniques are used, the charges are based on how long a circuit is used over time i.e. How long is the call going on? Whereas in packet switched technology the charges are calculated on the amount of data carried which is used by the services provider’s capacity. Whereas, always on connectivity is possible
Packet switched technology with always-on connectivity when combined with higher data rates, it creates more possibilities for new applications. With the advent of GPRS, the growth of mobile or PDAs like Blackberry started increasing.
While to develop more capabilities of GPRS, further advances were made in it and another system called EDGE or Enhanced GPRS, EGPRS was developed.
Which switching is used in GPRS?
Packet switched data is used in GPRS technology and not circuit switched data. This technique makes more efficient use of available capacity. The reason for this is that most of the data transfer occurs in a “bursty” fashion. In this, the transfer takes place in short peaks, while it is followed by breaks when there is little or no activity.
According to a traditional approach, a circuit was permanently switched for a particular user. This is called a circuit switched mode. According to the “bursty” nature of the data transfer, this means that there are some periods when it is not carrying any kind of data. To improve this situation, the overall capacity is shared. among several users.
To achieve this, the data is split into packets and tags that are inserted in the packet so that it can be delivered to the destination address. Packets are also transmitted to them from different sources through links. It is not possible that the data burst can also occur for different users at the same time, but in such a fashion, channels, or combined channels can be used more optimally by sharing the overall resource. This approach is called packet switching, and it used to be at the core of many cellular data systems, and in this case GPRS.
The future of GPRS?
By now you must have come to know that GPRS is a very crucial step in mobile evolution, and at the same time it opens up endless possibilities that too for application developers and users. The technology after GPRS will be either EDGE or UMTS (or both).
1. Enhanced Data rate for GSM Evolution (EDGE): It uses a new modulation scheme that provides up to three times higher throughput (that too For HSCSD and GPRS)
2. Universal Mobile Telecommunication System (UMTS): A new wireless technology in which new infrastructure deployment is used.
