4G DTU functions as a data pipe transmission in the Internet of Things system. It uses the 4G network of TD-LTE or FDD-LTE to realize wireless long-distance data transmission between the local serial port and the remote public network server. It is mainly used for remote data collection and remote control. project.
Advantages of 4G DTU vs. 3G/ GPRS DTU
High stability
With the development of the times, 2G/3G network withdrawal has become an inevitable trend. Now, 4G networks have covered 98% of administrative villages across the country, and the excellent performance of 4G DTU has been widely praised by users.
Good compatibility
4G DTU is a full Netcom terminal equipment. It not only supports the 4G networks of China Mobile, China Unicom and China Telecom, the three major domestic operators, but is also backward compatible with 3G/2G networks. If the local 4G network is not good, the device will automatically switch to other network frequency bands to continue providing data transmission for users.
Fast communication speed
4G DTU has a lower ping value than the 2G/3G module. The time from the module sending a data packet to receiving the server response is shorter. It is suitable for applications that require high response speed, such as remote alarm.
Large amount of communication data
The 4G network’s downlink rate can reach up to 100Mbps, and its uplink rate can reach up to 50Mbps. It provides customers with high-speed Internet access and wireless data connection functions, and is suitable for applications with large amounts of data transmission, such as serial camera picture transmission.
Functions of 4G DTU
- It has 1 RS485/232 interface and can realize data transmission from serial port to network through simple settings on the host computer.
- 4G full network, supports the three major domestic operator networks, and is backward compatible with 3G/2G.
- Built-in standard TCP/IP protocol stack supports two-way transparent data transmission.
- Supports DDNS and can access the center based on domain name and IP address.
- Supports TCP heartbeat link detection to keep the device always online.
- Supports automatic acquisition command settings, and the device actively reports data.
- Adaptive Modbus RTU /TCP protocol, can connect to most PLC devices and configuration software.
- Support equipment to run software and hardware self-checking technology and self-repair operating faults.
- It adopts industrial-grade design, wide voltage, anti-reverse connection, anti-static and anti-surge.
Applications of 4G DTU
Today, with the increasing development of the Internet, 4G DTU is used more and more widely, such as in smart agriculture, smart water affairs, smart meter reading, smart transportation, smart buildings, smart fire protection, smart homes, environmental monitoring, industrial automation and other fields. It provides help for information and industrial integration among various industries, and has gradually developed into a core technology for Internet of Things applications.
