The gateway for accessing NB-IoT networks carries out turn biography of data, can so make the application scenarios of gateway more, including operator's signal
In obstructed wild environment；
Gateway sets 2 kinds of operating modes, is the operating mode under automatic method of work A under normality, has personnel to need when nearby
Gateway actively to be connected into the operating mode then entered when row data communication under manual work method M, automatic method of work A
For cycle dormancy, the low power mode of operation waken up, since the data volume that things-internet gateway is usually acquired and transmits is little, because
This periodic duty data communication normal enough, then cycle dormancy, wake up and greatly reduce the energy consumption of gateway.
