TCP Protocol Serial Port Data Transmission in 4G LTE modem
Many devices with the function of serial port management can not be used to manage and access data in the network. We can use advanced TCP/IP technology and management methods to transform these devices. The 4G LTE modem based on LTE cat 4 cellular signals is the product of such a networking environment. In this paper, the serial port data flow based on TCP/IP is described, the overall solution of a 4G LTE modem system based on the combination of hardware and software is proposed, and the overall composition, framework, and application architecture of the hardware system are analyzed.
The full name of the 4G LTE modem is the data transmission unit, which is a wireless terminal device 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.

Communication principle of 4G LTE modem
The main function of the 4G LTE modem is to transmit the data of remote devices back to the background center through wireless means. To complete the transmission of data, we need to establish a complete set of data transmission systems. The system includes a 4G LTE modem, client device, mobile network, and background center. At the front end, the 4G LTE modem is connected to the customer's device via an RS232 or RS485 interface. After the 4G LTE modem is powered on, first register to the LTE cat 4 network, and then establish a SOCKET connection with the background center set in the 4G LTE modem. The background center is the server of SOCKET, and the 4G LTE modem is the client of the SOCKET connection. Therefore, only the 4G LTE modem cannot complete the wireless transmission of data, and it also needs the cooperation of background software. After the connection is established, the front-end device and the back-end center can perform wireless data transmission through the 4G LTE modem, and the transmission is bidirectional.
4G LTE modem applications
4G LTE modem has 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 application is the same. Most of them are 4G LTE modems connected to industrial equipment and then establish a wireless communication connection with the background. Today, with the increasing development of the Internet of things, the 4G LTE modem is used more and more widely. It provides help for industrial integration among various industries.
4G LTE modem is a terminal device based on the LTE cat 4 networks, supporting PPP, TCP/IP, UDP, ICMP, and other communication protocols, providing users with fully transparent wireless data transmission.
Quasi-industrial design, providing standard RS232/RS485/TTL interface, which can be directly connected with RTU, PLC, intelligent instrument and other lower computer equipment in various industrial fields. A transparent communication mode is adopted, so that non-IP system equipment can easily access the LTE cat 4 network and the Internet through the serial port, and the network management of field data can be realized without upgrading the original equipment.
The 4G LTE modem G786 equipment adopts a safe and transparent transmission mechanism, and is applicable to the data transmission services of users in various industries, especially to the intermittent, sudden, frequent, and small amounts of data transmission, and especially to the development of applications and application systems in the M2m field. With the further promotion of industry information application, it has been widely used in power monitoring, remote meter reading, oil pipeline monitoring, industrial control, environmental protection data acquisition, meteorological data acquisition, water grain monitoring, water conservancy monitoring, earthquake monitoring, street lamp monitoring, public utilities, urban water supply, traffic information release, and other industries and fields.
