Advantages of GPRS Wireless internet

Compared with the original GSM dialing mode of the circuit Exchange data transmission mode, GPRS is packet switching technology. Because of the use of "teaming" technology, users can be free of Internet access to the pain (the situation is probably similar to the use of the download software netants). In addition, the use of GPRS Internet access and WAP and different, with WAP Internet, such as at home, the Internet, the first "dial-up connection", and the Internet can not use the phone line at the same time, but GPRS is more advantageous, download information and call can be carried out simultaneously. Technically speaking, voice transmission (ie call) continue to use GSM, and data transmission can use GPRS, so that the mobile phone application to a higher level. and the development of GPRS technology is also very "economic", because only need to use the existing GSM network to develop. GPRS is widely used, including through the mobile phone to send and receive e-mail, browsing on the internet and so on.

Now the slogan of the mobile phone is "alwaysonline", "Ipinhand", using GPRS, the data packet sent and accepted, which means that users are always online and according to flowmeter fees, quickly reduce the cost of services. To continue in the dystocia state of China Mobile/Unicom WAP tariff policy, if the CSD (Circuit exchange data, that is, commonly said dial-up data, Europe-Asia WAP business use of the load mode) to implement in GPRS, it means that dozens of people together to bear the original cost of one person.

And GPRS's biggest advantage is: its data transmission speed is not WAP can match. The current GSM mobile communication network transmission speed of 9.6K bytes per second, GPRS mobile phone at the beginning of this year has reached 56Kbps transmission speed, to now has reached 115Kbps (this speed is commonly used 56Kmodem ideal rate of twice times). In addition to the advantages of speed, GPRS also has the "forever online" characteristics, that is, users at any time to maintain contact with the network. For example, when users visit the Internet, they click on a hyperlink, mobile phone on the wireless channel to send and receive data, the home page is downloaded to the local, no data transmission, the mobile phone into a "quasi-sleep" state, the mobile phone released by the use of wireless channels to other users, when the network and users also maintain a logical connection between , when the user clicks again, the mobile phone immediately requests the wireless channel to transmit the data to the network, but does not have to redial after the disconnection like the ordinary dial-up Internet to surf the net.
