Openwrt router industrial-grade 4 g tech-oriented pathways by DTU digital communication module also largely on using up the defect of traditional WiFi router, the current communication three carriers launched unlimited package fee like indoor pull of the cost of optical fiber, in the network catchword: "people don't have money, but can not be no WiFi" in an age of this spread to all walks of life and consumer better, card can be used directly, without broadband, avoid wiring,

Can directly solve problems such as: (1) there is no network; in rural (2) too much pasture cloth wire/cable high cost; (3) fishing pond cloth line too much trouble, (4) parking WiFi signal distance too far; (5) the partition is too much, the WiFi signal is not good; (6) the mountain there was no electricity and Internet, etc.
The development of information era, 4 g routing functions are widely used in various industries are: teaching/power/oil/coal/financial/communication/thermal/industrial control/weather/hydraulic/municipal transportation industry needs the type of remote monitoring field,
Now common specific projects are: charging pile applications; The vending machine applications. Road remote monitoring applications. Intelligent electronic housing applications. Solar remote monitoring applications. Logistics tracking applications. Remote environmental monitoring; Application in the field of environmental protection, etc.
