China:
Why would a network 4G industrial router have a watch dog? The watchdog is actually a kind of visual statement that the watch dog is faithful to the home guard. However, the watchdog of 4g industrial-grade router is an activation mechanism, which can be divided into two types: software watchdog and hardware watch dog.

Software watchdog is added in the main program monitoring mechanism. To prevent program errors, memory overflows, and so on, add detection code into the software. Once a software exception is found, or an error is found, the guard code will restart the software.

The hardware watch dog actually adds an extra microcontroller, running a small program to detect the entire device program. Software watch dog can also be abnormal, once the entire program crashes, software watch dogs cannot wake up. The main program has many functions, complex structure and is relatively easy to abnormal. And the hardware watch dog is a simple program, does not appear the exception. Therefore, once the main program is abnormal and the software watch dog cannot wake up, the hardware watch dog will turn off the power and restart, and reset the program of the whole device.

Due to the fact that full-netted 4G routers are generally used in industrial unmanned places, equipment stability is very important, so hardware watchdog is an indispensable function of full-netted 4G industrial routers.
