摘要
无线应用在上海电力数字化进程的发展中需求越来越强烈,以营销的抄表系统和通信网络应急系统为代表。目前,无线技术呈现多元化发展,如GPRS、CDMA1X等,并已大量商用;而一些基于专网应用或数据应用的还有类似卫星Modem、CDPD、MOB ITEX以及基于IEEE 802.16标准的W iMAX等,都是既可以实现语音也可以实现数据传输的无线网络和技术,给用户提供了多样选择的机会。文章通过对上海电力无线应用现状描述、无线技术发展的比较、无线应用的需求分析,提出了适合上海电力系统的无线应用建议。
The requirement of wireless application in the process of Shanghai electric power digitization is increasing rapidly. Such requirement comes from, for example, the remote meter reading system and emergency system of telecommunication network. Wireless technology is developing towards a multivariate direction, such as GPRS and CDMA1X etc. , which have been widely used commercially. Some technologies based on data and private telecommunication network applications such as Satellite Modem,CDPD,MobiTex and WiMAX based on IEEE 802.16 standard can provide users more choices since they can realize both voice and data transmission. This article describes the actuality of Shanghai electric power wireless application, compares various wireless technologies, analyzes requirements of wireless application and brings forward suggestions suitable for the wireless application in Shanghai electric power system.
