The difference between 4G Industrial Router and 4G DTU is explained in Detail


4G industrial router and 4G DTU both realize the wireless network data transmission function, and the differences between them are mainly from the use method, appearance interface and application environment, etc. Today, we will introduce some differences between 4G router and 4G DTU.

Different methods of use:

4G industrial router:
The 4G router can convert Ethernet and fieldbus communication protocols. It only needs to set the IP address specified by the 4G router 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 realized.

4 g DTU:
The main purpose of 4G DTU is to realize dial-up rather than a real gateway. For example, 4G DTU can be used as a new network device after the dialing process of the access terminal device is completed, and the terminal device address can be used as the binding address of 4G DTU.

Different application environments:
4G router: usually with VPN/APN function, with private network encryption, in addition, the industrial 4G router with WIFI function is suitable for outdoor WIFI wireless signal coverage projects and similar public transport WIFI and shopping mall WIFI sharing projects.

4G DTU: the transmission distance of field terminals is relatively scattered and the data communication rate is relatively high, 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. For example, the charging pile remote monitoring system, environmental monitoring system, real-time monitoring of energy consumption, monitoring and application of dam water conservancy projects, etc.

Different network interfaces:
4 g router: provides one network interface of data access, terminal equipment needs only the IP address of the mouth to the 4 g router in the network as a gateway to the IP address of the terminal device must use specified or specify the IP address in the address period, 4 g router to and specify the IP address of the server host or server host IP address sections for data exchange, and all the other 4 g router is not set between the address of the can't communicate.

4 g DTU
4 g DTU: DTU data access in general also provides a serial port or network interface, but their use is used to dial, not used to do in the true sense of the gateway, such as serial interface 4 g DTU after completion of the access terminal dial-up, 4 g DTU as terminal equipment of a new network equipment, terminal equipment address using the new network equipment binding address; However, 4G DTU of network interface is similar to ADSL of telecommunication to connect to the Internet, which generally requires the device to complete a dial-up action.

Different anti-interference of server network:
When using 4G router, the data transmission must comply with the preset regulations, otherwise, the correct communication cannot be carried out, reducing the possibility of unnecessary network traffic; at the same time, according to the sent serial number and other key processing, to ensure that the server data will not be replay or retransmission.

4G DTU does not carry out relevant filtering during data transmission, so other machines can directly send some illegal information to the device terminal through the network. Meanwhile, 4G DTU increases unnecessary network traffic. At the same time, the data is not processed accordingly, which may lead to the replay or retransmission of wireless data, which will lead to the abnormity of the system, thus causing potential security risks.

The E-Lins Technology H685 series 4G router with Ethernet is a compact, ruggedized 3G/4G/LTE cellular networking solution designed for mission-critical connectivity in the most challenging environments.
