The 4G module refers to a product whose hardware is loaded into a specified frequency band, whose software supports standard LTE protocol, and whose software and hardware are highly integrated and modularized. It has the characteristics of fast communication speed, wide network spectrum and flexible communication. The hardware integrates radio frequency and baseband on a PCB board to complete the functions of wireless reception, transmission and baseband signal processing. The software supports voice dialing, short message sending and receiving, dial-up networking and other functions.


As the field of industrial control communication, the downlink rate of the 4G module with large amount of communication data can reach 150 Mbps and the upstream rate can reach 50Mbps. It provides high-speed Internet access and wireless data connection functions for customers, and is suitable for applications with large amount of data transmission, such as remote video surveillance.


Industrial tablet computers in special industries require fast communication speed. At this time, 4G module has a lower Ping value than 2G/3G module. The time for module to send data packets to receive the server response is shorter. It is suitable for applications requiring high response speed, such as remote alarm.
