GPRS具有传输速度高、接入时间短、永远在线以及按流量收费等优点,文中针对其特点提出了一种基于GPRS业务进行数据传输的方案,利用现有的GPRS模块TC 45设计了一种基于GPRS业务的通用低速率数据传输终端,并给出了其软硬件实现。
GPRS has the advantages of high transmission speed, short access time, always online and charging according to the traffic. According to the characteristics of GPRS, this paper proposes a data transmission scheme based on GPRS service. Based on the existing GPRS module TC 45, GPRS business universal low-rate data transmission terminal, and gives its hardware and software implementation.
