As a high-speed, efficient and cost-effective wireless system，GPRS has a wide range of network coverage, wide data bandwidth, adaptable, denominated by the data flow calculation advantage, the advantages of real-time online, especially for intermittent, and sudden or frequent , And a small amount of data transfer, but also for the occasional large amounts of data transmission, data collection and monitoring to meet the two-way data transmission. GPRS technology from the laboratory studies, areas to the official business within the trial, after a long, technologically advanced and reliable. GPRS equipment data monitoring terminal transmission equipment can automatically attach a boot to the GPRS network, and data centers for real-time data in real-time online communication, high-speed transmission and high reliability.
