1. General

GPRS is General Packet Radio Service built on the basis of GSM network to provide packet data service. It works at the same frequency band, the same modulation and the same TDMA frame structure with GSM. GPRS can be implemented at existing GSM BSS by plug-in packet data card and associated updated software. Therefore, the system coverage is as same as GSM network. GPRS users can transmit and receive data from end to end by packet model. Packet data service is highly efficient and low cost for customers, for it does not occupy the circuit switched network resources. In this way, GPRS is a great communication channel for interrupting and bursting data transmission.

Maximum GPRS bandwidth can reach 171.2Kb/s and the actual application is 40~100Kb/s. Provided TCP/IP protocol connections on this channel, GPRS network can be applied on Internet connection and data transmission, etc..

GPRS is a kind of mobile packet data service that provides high speed wireless IP connection between mobile users and data network. It is developed with packet switch technology; each user can occupy multiple radio channels, at the same time, one single radio channel can be shared by multiple users. Thus, radio resources are effectively utilized and the maximum GPRS bandwidth can reach 171.2Kb/s. Remaining online all the time, users pay merely for the data transmitted and received because of this technology.
