Abstract： The wireless data transmission terminal is also called "the mobile phone in the industrial field", and its data transmission principle is similar to that of the mobile phones we usually use. The use of 2G/4G networks to transmit data is common in traditional data transmission units. 2G/4G networks have problems such as small bandwidth, large delay, and limited number of access terminals. Therefore, the traditional data transmission unit is not suitable for the Internet of Vehicles and large-scale industrial control fields. This paper innovatively combines 5G technology and DTU(Data Transfer Unit), to design a 5G data transmission terminal with high reliability, namely 5G-DTU. Its main processor is Rockchip′s RK1808 chip, which integrates 5G communication module, WiFi module and interface module. Therefore, 5G-DTU can provide 2.4 G and 5 G dual-band wireless access for external devices, and a wealth of peripheral interfaces. Finally, the test results show that the 5G-DTU has the characteristics of high data band, low time delay and high reliability.
