The Difference between Industrial Wireless Routers and DTU

An industrial-grade wireless router is an IoT wireless communication router that transmits network signals only to the desired port. The gateway can convert standard Ethernet and industrial Ethernet, wireless and wired interfaces, or Ethernet and fieldbus communication protocols. Data Transfer unit (DTU) is a wireless terminal device specially used to convert serial port Data into IP Data or convert IP Data into serial port Data for transmission through wireless communication network. Just like DTU, industrial router realizes wireless network data transmission function, and the difference between the two is mainly divided from three aspects, namely appearance interface, usage method and application environment.

Different shapes and ports:

Industrial wireless routers provide multiple network interfaces for data access.

DTU generally provides serial port access.

Different ways of use:

Industrial wireless routers can convert standard Ethernet and industrial Ethernet protocols, wireless and wired interfaces, or Ethernet and fieldbus communication protocols. Only the IP address of the terminal network port is needed as the gateway. The terminal equipment must use the specified IP address or address in the specified IP address segment to exchange data with the server host in the specified IP address segment or the server host in the IP address segment. All other addresses that are not set cannot be communicated.

The purpose of DTU is to dial, not to be a gateway in the real sense. For example, after the DTU of serial interface finishes dialing in the access terminal device, it is a new network device of terminal device, and the address of terminal device is the address of the new network device binding.

Different applications:

Industrial router can support APN/VPDN special network, and add another layer of encryption transmission on the basis of special network, which is more suitable for applications such as traffic monitoring, security monitoring, financial self-service terminal networking, street lamp monitoring, power monitoring and other occasions requiring massive data real-time transmission. In addition, industrial 4G routers with WIFI function are suitable for outdoor WIFI wireless signal coverage projects and similar public transportation WIFI.

DTU is suitable for applications where the transmission distance is dispersed and the data communication rate is appropriate. In general, the real-time performance of DTU can meet the requirements of most industrial applications. However, for some specific applications, it may not be appropriate if the average delay of 1-2 seconds or so cannot be sustained.
