The difference between 4G DTU and 4G router (2)

The difference between 4G router and 4G DTU

4G industrial wireless router and 4G DTU are also used for transparent transmission of wireless network data of industrial equipment. However, there are also significant differences between the two, and the differences between the two are mainly distinguished from three aspects: appearance interface, usage method and application environment.

8. Security of wireless access

The data exchange using 4G routers uses the secure tunnel established between the wireless router and the communication server. All data exchanges can only be from end (terminal device) to end (server), and any other intermediate-to-end data cannot be effectively carried out. communication, which means that the wireless network provider cannot access any systems on either side of the communication.

Using 4G DTU data exchange uses the data exchange process within the wireless network provider, allowing the wireless network provider to easily access any system on both ends of the communication.

9. Anti-interference of 4G router and 4G DTU terminal equipment

The core system of the 4G router adopts an embedded operating system, which only provides a few data ports that can be used. There is only one routing relationship with the terminal device, so the terminal device cannot reach other terminal devices, and cannot access other terminal devices even if they are of the same type. Terminal equipment, even if one terminal equipment is controlled by a virus or an outsider, it only affects this terminal equipment, and the others are not affected.

The terminal equipment using 4G DTU has a certain relationship with 4G DTU, and can easily access other terminal equipment. If a terminal equipment is controlled by a virus or an outsider, all terminal equipment and the central server system will be seriously threatened.

10. Equipment status monitoring

The 4G router can monitor the status while it is working. Through the log information, you can basically know where the problem is and the corresponding solution.

Condition monitoring cannot be performed when using 4G DTU, so when encountering problems, it is more troublesome or troublesome to check.

11. Setting of server network routing

When using a 4G router to access the terminal device from the server, it is necessary to add a 4G router to the terminal device on the server and use the communication server as the gateway, which reduces the complexity of the network.

When using 4G DTU to access the terminal device from the server, a route to the terminal device is added to the server, and the access interface of the wireless network provider is used as the gateway (or related routing).

12. Anti-interference of server network

The use of 4G routers must comply with pre-set regulations during data transmission, otherwise it will not be able to communicate correctly, reducing the possibility of unnecessary network traffic; at the same time, it can be processed according to the serial number sent to ensure that server data will not be used. Replay or resend.

Using 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, and 4G DTU increases unnecessary network traffic; at the same time, the data is not processed accordingly, It may lead to the replay or retransmission of wireless data, which will lead to the abnormality of the system, thus posing a security risk.

13. 4G router and 4G DTU data compression transmission

Using 4G routers can compress large data packets before transmission, thereby reducing network traffic, increasing network bandwidth, and improving the efficiency of data transmission (except for pictures and images with high compression ratios).

When using 4G DTU, data is generally not compressed during data transmission.

14. Processing of data exchange between 4G router and 4G DTU

The communication server is the core of the 4G router, so the central server must be installed with a host for the 4G router to communicate with, and all device exchange data must be encrypted, decrypted, verified, and routed by it. There is no other intermediate when using 4G DTU. server, but directly connect to the central server.
