View the difference between 4G router and 4G DTU

4G industrial wireless router and 4G DTU are also used for wireless network data transmission of industrial equipment. But there are also significant differences between the two, and the differences between the two are mainly from the appearance of the interface, the use of methods and the application environment.

1. Appearance interface the appearance interface of 4G router usually has a network port, which provides wireless networking functions for the network port devices and requires the network port devices to actively access the center to complete data transmission. In general, 4G router will provide a variety of network interface modes of WAN port, LAN or freely switched WAN/LAN port, which can be customized to match the interface according to the connection mode in the project.

The external interface of 4G DTU generally only provides the networking mode of serial port interface. 4G DTU is mainly used for two-way transmission between serial port data and IP data. And some projects need to use both the network port, but also need to use the serial port how to do? In the current era of rapid technological development, 4G router and 4G DTU function have been integrated.

2. Methods 4G router can be used to convert Ethernet and fieldbus communication protocols. Only the IP address specified by 4G router needs to be set in the terminal device as the gateway. If the specified IP address (or the specified IP address segment) is not set, the communication function cannot be implemented. The primary purpose of 4G DTU is to achieve dial-up, not gateway in the real sense. For example, 4G DTU can be used as a new network device after dialing into the terminal device, and the terminal device address can use this 4G DTU binding address.

3. 4G router in the application environment usually has VPN/APN function and private network encryption. In addition, industrial 4G router with WIFI function is suitable for outdoor WIFI wireless signal coverage projects and similar public transport WIFI and mall WIFI sharing projects. However, 4G DTU is applied in the field terminal with scattered transmission distance and high data communication rate, so the real-time performance of 4G DTU can meet the requirements of most industrial fields and is usually used for data acquisition and monitoring system. Such as charging pile remote monitoring system, environmental monitoring system, real-time monitoring of energy consumption, dam water conservancy project monitoring application.
