4G module refers to the hardware loaded to the specified frequency band, the software supports the standard LTE protocol is highly integrated hardware and software modular products in general. With fast communication speed, wide network spectrum, communication flexibility and other characteristics. The hardware integrates RF and baseband together PCB wireless receiving, transmitting, baseband signal processing functions completed on a small board. The software supports voice dialing, SMS sending and receiving, dial-up network and other functions. 4G through high-speed connection, the module real-time transmission of all terminal business data and equipment operation status to the business center, real-time monitoring of the terminal equipment operation status through the management monitoring platform, timely inspection of equipment failure. It greatly improves the efficiency in terms of operation cost, operation scale and service timeliness.

Good compatibility

4G module supports FDD LTE/TD-LTE two kinds of LTE can also be backward compatible with 2G/3G, support LTE-FDD, LET-TDD, W **, TD-S **, **, G and other frequency bands.

Large communication data volume

The 4G module has a maximum downlink rate of 150Mbps and an uplink rate of up to 50Mbps, providing customers with high-speed Internet access and wireless data connectivity such as remote video monitoring.

Fast communication speed

4G module has lower ping value than 2G/3G module and shorter time from sending data packet to receiving server response, which is suitable for applications requiring higher response speed, such as remote alarm.
