随着以CDMA 2000为代表的3G技术飞速发展,基于3G的远程数据通信应用将逐渐增多,如何提高通信系统的性能成为人们所关心的一个主要问题。文章提出了一种基于CDMA 2000的无线终端数据通信方案。该方案设计主要采用测量单元、无线终端、主站数据处理系统以及CDMA 2000网络实现对远程数据的实时采集和传输。该方案能可靠实现远程数据通信功能,为多种实际应用提供经济、高效的透明数据传输。可广泛应用于能源、金融、交通和环保等领域。
With the rapid development of 3G technology represented by CDMA 2000, the application of remote data communication based on 3G will gradually increase, and how to improve the performance of communication systems has become a major concern. This paper presents a wireless terminal based on CDMA2000 data communication scheme. The program design mainly uses measurement unit, wireless terminal, master data processing system and CDMA2000 network to achieve real-time remote data acquisition and transmission. This scheme can realize the long-range data communication function reliably, offer the economical, efficient transparent data transmission for many kinds of practical applications. Can be widely used in energy, finance, transportation and environmental protection and other fields.
