摘要
在详细分析通用分组无线电业务(GPRS)/码分多址(CDMA)数据终端设备(DTU)在行业应用中的优缺点的基础上,提出了一种新型的GPRS/CDMA水情自动测报系统。该系统具有整体功耗低、通信方式灵活、参数设置方便、运行费用低等特点;同时,文中还详细介绍了其中点对点协议(PPP)的实现。
This paper gives a detailed description of the GPRS / CDMA DTU s advantages and disadvantages, and proposes a new method of transmission for GPRS / CDMA network. This kind Of GPRS / CDMA telemetry system has many advantages such as low power consumption, flexible transmission mode, easy parameter setup, low operation cost, etc. This paper also discusses in detail the realization of the PPP protocol.
