The combination of mobile communications and practical applications can provide users with flexible and efficient services. In the era of booming development of the Internet of Things, as the cost of 4G networking drops, 4G technology is widely used in all walks of life.
The 4G module mainly relies on cellular network signal transmission to achieve network communication. The 4G network itself has the characteristics of high spectral efficiency, high speed, and low delay, so the 4G module has become an ideal choice for many industry applications.
Currently, a common usage of 4G modules is to transparently transmit with remote servers. For example, the 4G module is connected to the charging pile and transmits a large amount of real-time data to the server platform of the remote monitoring center, which can realize remote unified management of data, thus saving manpower and material resources.
In addition, many industry applications also require wireless communication between devices and devices that are far apart. Since the 4G module does not have a fixed public IP, two 4G modules cannot directly transmit point-to-point data.
The 4G module developed and produced by Zongheng Intelligent Control provides a point-to-point mapping function, allowing the 4G module to connect to the Zongheng Transmission Cloud. The Zongheng Transmission Cloud acts as an intermediary to interact with the devices connected by the two 4G modules, and can perfectly realize the communication between the serial devices. Peer-to-peer communication.
User equipment A is connected to 4G module 01 through the 232/485 serial port, and user equipment B is connected to 4G module 02 through the 232/485 serial port. Data transmission between user equipment A and B can be realized without any other complicated configuration.
