因此GPRS遠(yuǎn)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(dá)到2A，這對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、移動頻段，支持CoAP快速與云平臺實現(xiàn)對接，目前支持的云平臺有OneNET、eCoud、Aiyun、ZWS IoT等，極大地降低了客戶跟云平臺的對接難度。且模塊支持FOTA遠(yuǎn)程差分升級，僅需上傳數(shù)據(jù)量很小升級包的差分文件，即可完成升級。
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)無線互聯(lián)系統(tǒng)級解決方案專家，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，共同助力中國物聯(lián)網(wǎng)產(chǎn)業(yè)發(fā)展。
