What are the types of DTU?

What are the types of DTU:

DTU (Data Transfer Unit) is a wireless terminal device specially used to convert serial data into IP data or convert IP data into serial data for transmission through wireless communication network.

The main function of DTU is to transmit the data of the remote device back to the background center through wired/wireless mode. To complete the data transmission, it is necessary to establish a complete data transmission system. Included in this system: DTU, client equipment, mobile network, background center. At the front end, DTU and customer's equipment are connected through 232 or 485 interface. Therefore, only DTU cannot complete the wireless transmission of data, and it needs to be used together with the background software. After the connection is established, the front-end device and the back-end center can perform wireless data transmission through DTU, and it is a two-way transmission. The new generation of DTU has various degrees of development in simple data acquisition, multimedia display, data processing and so on.

Types of DTUs:

The industrial 4G data transmission terminal is an IP MODEM (DTU) terminal based on a cellular wireless communication network. It is a 4G serial converter specially used to convert LTE/TDD/FDD serial port to wireless data or wireless to serial data. The 4G transmission terminal DTU products include 4G DTU, 3G DTU, LTE DTU, TDD DTU, FDD DTU, GPRS DTU, TDD-LTE serial converter, FDD-LTE serial converter, etc.

DTU is a wireless data transmission terminal module, which uses 2G, 3G and 4G networks for data transmission. After the serial port data is sent to the IP address of the remote central server, it is sent to the TCP or UDP packet.
