What is a wireless data terminal?

Wireless data terminal, also called wireless data transmission terminal, is a terminal module used to realize wireless data transmission.

The wireless data terminal is usually connected with the lower computer to realize the purpose of wireless data transmission. Because its transmission principle is basically the same as the mobile phone we usually use, it has the title of "industrial mobile phone".

Typical devices include wireless data transmission, wireless routers, wireless modems and other devices. The following are the relevant parameters of DTU, which is the most widely used reference.

Provide users with high-speed, stable and reliable virtual private network, with always-on data terminal and various protocol conversion. For users with network traffic control, the product supports the functions of voice, short message and data online triggering and automatic disconnection after timeout. At the same time, it also supports the functions of double data center backup and multiple data centers receiving data synchronously.

Characteristics of wireless data terminal:

1, DNS automatic acquisition: DNS is automatically acquired, and it is no longer necessary to manually configure and input DNS, thus avoiding the serious phenomenon that DTU equipment crashes due to the abnormal DNS server selected!

2. Perfect protocol stack: The new system is loaded with perfect TCP/IP protocol stack. The original system used a lightweight TCP/IP(LPIP) protocol stack, which was cut. The new system adopts perfect TCP/IP protocol stack and has excellent network communication performance.

3. Multi-center support: customer data can be sent to the monitoring center designated by the customer at the same time, with a maximum of 256 sending centers supported.
