What is GPRS?
GPRS is General Packet Radio Service (General Packet Radio Service) of the English abbreviation, is in the existing GSM system on the development of a new packet data bearer service. GPRS and the existing GSM voice system is the most fundamental difference is that GSM is a circuit-switching system, while GPRS is a packet switching system. GPRS is a packet switching system. Therefore, GPRS is particularly suitable for intermittent, bursty or frequent data transmission of small amounts, as well as for occasional transmission of large amounts of data. This feature is suitable for most mobile connectivity applications.
What are the advantages of GPRS?
Real-time online: "Real-time online" means that the user is connected to the network at all times. For example, when the user accesses the Internet, the phone sends and receives data on the wireless channel, even if there is no data transmission, the phone has been connected to the network, not only by the user side of the initiation of data transmission, but also from the side of the network at any time to start the push class business, not like ordinary dial-up as disconnected from the Internet, you have to re-dial in order to surf the Internet.
By volume billing: Users can be online all the time and charged according to the number of packets received and sent by the user, and when there is no data traffic delivery, users are not charged even if they hang on the Internet.
Fast login: GPRS users are always attached to the GPRS network as soon as they turn on their computers, and each time they use it, they only need an activation process, which usually takes only 1-3 seconds to log on to the Internet right away.
High-speed transmission: GPRS uses packet-switching technology, with a maximum theoretical data rate of 171.2 kb/s. Circuit-switched data services, at a rate of 9.6K bits per second, are therefore similar to the relationship between circuit-switched data services (referred to as CSD) and GPRS, as is the case for the difference between a 9.6K Modem and a 33.6K or 56K Modem.
Free switching: GPRS also has the advantage that data transmission and voice transmission can be carried out simultaneously or switched. That is to say, users can receive voice calls while surfing the Internet with their cell phones. This means that users can receive voice calls while surfing the web on their mobile phones.
What does GPRS bring to the user? In particular, what are the applications that are different from the existing GSM?
GPRS mobile data services can provide users with a wealth of applications, such as:
Mobile commerce: including mobile banking, mobile financial management, mobile trading (stocks, lottery), etc.
Mobile information services: information on demand, weather, travel, services, web pages, news and advertising, etc.
Mobile Internet services: web browsing, email, etc.
Mobile Internet services: web browsing, mobile phone, mobile Internet services. Email, etc.
Virtual Private Network (VPN) services: mobile office, mobile healthcare, etc.
Location-based services: location query, navigation in hotels and similar service industries, etc.
Multimedia services: video telephony, multimedia messaging, online gaming, music, video on-demand, etc.
Personal service services: customized services such as PIM, etc.
Personal service business: PIM and other customized business for individuals, and so on.
It is worth noting that GPRS also has the characteristics of resource **** enjoyment, rich bandwidth, etc., which is not a business in itself, but a better way to carry the network, so even the same application will be enhanced because of the above characteristics of GPRS, of course, due to the technical characteristics of the GPRS itself, there are also some applications that are particularly suitable for the GPRS network services, such as Online chatting, mobile stock trading, remote monitoring, remote counting, and other data services with low traffic and high frequency transmission.
