“局(ju)域(yu)网(wang)(wang)+远(yuan)程(cheng)通(tong)信(xin)” 是典型的(de)物联网(wang)(wang)系(xi)统架构(gou)。 它(ta)是指智能设备(bei)节点(dian)使(shi)用局(ju)域(yu)网(wang)(wang)通(tong)信(xin)技术到网(wang)(wang)关(guan)，网(wang)(wang)关(guan)使(shi)用远(yuan)程(cheng)通(tong)信(xin)技术连接平台(tai)。有线以太网(wang)(wang)、 WIFI、电力(li)线载波(bo)、 ZigBee、 ZWave 等都属(shu)于这(zhei)种方式。这(zhei)种方式每个(ge)智能设备(bei)通(tong)信(xin)模块成本(ben)较(jiao)低，长期运行不需要(yao)每个(ge)节点(dian)支付 3G/4G 网(wang)(wang)络费(fei)用、也不需要(yao)安装点(dian)有 3G/4G 信(xin)号。因而适合设备(bei)节点(dian)数量多、运行成本(ben)敏感(gan)、远(yuan)程(cheng)网(wang)(wang)络信(xin)号无法保障（如(ru)地(di)下停(ting)车(che)场）的(de)场合。 这(zhei)种局(ju)域(yu)网(wang)(wang)络通(tong)信(xin)即(ji)物联网(wang)(wang)“最后(hou) 1 公里”。
