Common Applications of Cellular modems
Cellular Modem is a wireless terminal device that is 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.
Advantages of Cellular modems:
● Rapid and flexible networking, short construction period, and low cost
● Wide network coverage
● Good security and confidentiality
● The link supports always online, billing by traffic, and low user cost.
What are the components of cellular modems' structure?
The main function of Cellular modems is to transmit the data of remote equipment back to the background center through wired or wireless means. To complete the transmission of data, we need to establish a complete set of the data transmission system. The system includes Cellular modems, client devices, mobile networks, and background centers. At the front end, the Cellular modems are connected to the customer's equipment via an RS232 or RS485 interface. Therefore, only Cellular modems can not complete the wireless transmission of data, but also needs the cooperation of background software. After the connection is established, the front-end equipment and the background center can transmit wireless data through Cellular modems, and the transmission is bidirectional. The new generation of cellular modems has different degrees of development in simple data acquisition, multimedia display, data processing, and so on.
Cellular modems application field
Cellular modems have been widely used in power, environmental protection, LED information release, logistics, hydrology, meteorology, and other industries. Although the industry of application is different, the principle of the application is the same. Most of them are Cellular modems connected with industry equipment, such as PLC, SCM, and other automation products, and then establish a wireless communication connection with the background. With the development of the Internet, Cellular modems are used more and more widely. It provides help for the information and industrial integration of various industries and industries. It has also gradually developed into the core technology of Internet of Things applications.
