GPRS(General Packet Radio Service)是通用分组无线业务的简称。GPRS是GSM Phase2.1规范实现的内容之一,能提供比现有GSM网9.6kbit/s更高的数据率。GPRS采用与GSM 相同的频段、频带宽度、突发结构、无线调制标准、跳频规则以及相同的TDMA帧结构。因此,在GSM系统的基础上构建GPRS系统时,GSM系统中的绝大部分部件都不需要作硬件改动,只需作软件升级。-GPRS (General Packet Radio Service) is a General Packet Radio Service abbreviation. GPRS GSM Phase2.1 norms to achieve one of the elements that can provide more than the existing GSM network 9.6kbit/s higher data rate. GSM and GPRS using the same frequency and bandwidth, unexpected structure, the wireless standard modulation, frequency hopping and the same rules TDMA frame structure. Therefore, in the GSM system builds on the GPRS system, the GSM system of most components do not need to make hardware changes, only for software upgrades.
