How 4G module transmits data

The 4G module is also called the Internet of Things gateway. It is the link between the sensing network and the traditional communication network. The 4G module is connected to the high-speed cellular network and transmits all terminal business data and equipment operating status to the business center in real time. Through the management and monitoring platform, the operating status of the terminal equipment is monitored in real time and equipment faults are discovered in a timely manner. Operating costs, business scale, service timeliness and many other aspects have greatly improved work efficiency.

Characteristics of 4G module

Good compatibility

The 4G module supports two LTE standards, FDD LTE/TD-LTE, and is also backward compatible with 2G/3G. It supports LTE-FDD, LET-TDD, WCDMA, TD-SCDMA, CDMA, GSM and other frequency bands.

Large amount of communication data

The 4G module’s downlink rate can reach up to 150Mbps, 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 remote video monitoring.

Fast communication speed

The 4G module 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.

How 4G module transmits data

The 4G module adopts transparent transmission mode, which is the most widely applicable and the most common operating mode. In the transparent transmission mode, the device directly parses any data received from the serial port into TCP or UDP packets and sends them. The specific analysis data is collected to the front-end of the relevant data terminal equipment and the back-end data center server for processing. Therefore, for different applications, 4G modules have plug-and-play functionality, which is simple and convenient.
