因此GPRS遠(yuǎn)程抄表便應(yīng)運(yùn)而生，它解決了人工抄表一系列問題，效率更高，更，用戶繳費(fèi)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(hào)差。而普遍的水氣表都要求是電池供電，因此這對(duì)表類的功耗提出了很高的要求，一般2G通信的瞬時(shí)電流可達(dá)到2A，這對(duì)電池性能的選型和成本控制增加了很大困難
ZG致遠(yuǎn)電子ZM7100 NB-IoT模塊支持電信、移動(dòng)頻段，支持CoAP快速與云平臺(tái)實(shí)現(xiàn)對(duì)接，目前支持的云平臺(tái)有OneNET、eCoud、Aiyun、ZWS IoT等，極大地降低了客戶跟云平臺(tái)的對(duì)接難度。且模塊支持FOTA遠(yuǎn)程差分升級(jí)，僅需上傳數(shù)據(jù)量很小升級(jí)包的差分文件，即可完成升級(jí)。
致遠(yuǎn)電子作為物聯(lián)網(wǎng)行業(yè)領(lǐng)軍企業(yè)，構(gòu)建工業(yè)無(wú)線互聯(lián)系統(tǒng)級(jí)解決方案專家，攜手工業(yè)互聯(lián)網(wǎng)領(lǐng)域戰(zhàn)略合作伙伴，聯(lián)合推出ZM7100 NB-IoT標(biāo)準(zhǔn)通信模塊，共同助力中國(guó)物聯(lián)網(wǎng)產(chǎn)業(yè)發(fā)展。
