在業(yè)務(wù)方面，水氣表上報數(shù)據(jù)多上報一次，有的甚至一個月上報一次，因此NB-IoT的工作模式非常適合這種業(yè)務(wù)模式。當(dāng)前水氣表比較常用的計數(shù)方式有干簧管脈沖計數(shù)和光電直讀計數(shù)，NB-IoT更適用于光電直讀計數(shù)。在采用光電直讀計數(shù)方式的燃氣表中ZM7100系列模組在PSM模式下功耗可達2uA，2400mAh的電池在信號覆蓋比較好的區(qū)域下，續(xù)航時間可達25年，在信號強度弱的情況下，發(fā)射功率4次重發(fā)，電池可續(xù)航達到15年。通常水氣表的壽命要達到10年左右，因此ZM7100系列模組能充分滿足當(dāng)前水氣表的功耗要求。
因此GPRS遠程抄表便應(yīng)運而生，它解決了人工抄表一系列問題，效率更高，更，用戶繳費更加便捷。但是，GPRS表也產(chǎn)生了一些問題，通訊基站用戶容量比較小，功耗高，信號差。而普遍的水氣表都要求是電池供電，因此這對表類的功耗提出了很高的要求，一般2G通信的瞬時電流可達到2A，這對電池性能的選型和成本控制增加了很大困難
