Basic knowledge of DTU

What is DTU?

The data transfer unit DTU (Data Transfer Unit) 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 a wireless communication network.

Broadly speaking, when communicating, the module units responsible for sending data information at both ends of the data transmission link are called DTUs. Under its action, format conversion and data collation and verification are performed on the transmitted information.

In a narrow sense, DTU generally refers to the lower-level GPRS/CDMA transmitting terminal equipment in wireless communication. The former is a module, while the latter is a device. The following descriptions refer to the latter (lower transmitting terminal equipment) unless otherwise specified.
