Lub ntse Lora dej ntsuas tau txais qhov tsawg-frequency narrowband micro-power wireless kev sib txuas lus thev naus laus zis, thiab siv qhov ruaj khov thiab txhim khu kev qha ncaj qha spectrum technology los xyuas kom meej qhov sib xws ntawm kev sib txuas lus ntawm qhov ntsuas dej; cov ntaub ntawv ntsuas dej yog sau los ntawm wireless concentrator. Tam sim no paub tab GPRS / 3G / 4G pej xeem network wireless kev sib txuas lus tau xa mus rau tom qab ntsuas kev nyeem ntawv, uas yog pheej yig, ruaj khov hauv kev sib txuas lus, thiab paub tab hauv kev siv tshuab.
