基于GPRS/CDMA无线数据传输业务广泛在移动办公、工业控制、远程遥测等多方面应用,网络运营商中国移动GPRS和联通CDMA各有其特点。本文从网络的覆盖、带宽、频谱等方面对当前主流的GPRS和CDMA进行了对比。同时,对即将应用的3G通信技术以及WiMAX技术进行了分析比较。最后,针对海事信息网络组件过程中,如何解决“最后一公里”的问题以及移动办公的解决办法进行了思考。
GPRS / CDMA wireless data transmission based on a wide range of applications in mobile office, industrial control, remote telemetry and other applications, the network operators China Mobile GPRS and China Unicom CDMA has its own characteristics. This article compares the current mainstream GPRS and CDMA from aspects of network coverage, bandwidth, spectrum and so on. At the same time, the forthcoming application of 3G communication technology and WiMAX technology were analyzed and compared. Finally, thinking about how to solve the problem of “last mile ” and the solution of mobile office in the process of maritime information network components.
