实时采集到的能源计量数据传输通常采用3种方式:Internet传输、GPRS传输、卫星传输。GPRS因其实时在线、使用方便、价格低廉等优点成为能源计量数据实时传输的首选方式。一、概述1.GPRS技术简介GPRS是通用分组无线业务(General Packet Radio Service)的英文简称,是在现有GSM系统上发展出来的一种新的承载业务,目的是为GSM用户提供分组形式的数据业务。GPRS采用与GSM同样的无线调制标准、同样的频带、同样的突发结构、同样的跳帧规则
Real-time collection of energy measurement data transmission is usually used in 3 ways: Internet transmission, GPRS transmission, satellite transmission. Because of its real-time online GPRS, easy to use, low cost and other advantages of real-time transmission of energy measurement data the preferred way. I. Overview 1. Introduction to GPRS technology GPRS is the abbreviation of General Packet Radio Service (GPRS), a new bearer service developed on the existing GSM system to provide GSM users with packet-based Data Business. GPRS and GSM using the same wireless modulation standards, the same frequency band, the same burst structure, the same skipping rules
