Introduction:
LTE Modem, also called LTE modem, is a kind of equipment that can realize the modulation and demodulation of LTE (packet switched) communication. It was born under the background that with the rapid development of wireless data services, more and more devices began to require wireless communication capabilities. Many applications that never existed have turned from ideal to reality, such as wireless internet access, remote monitoring, remote data acquisition and so on.
The modem mainly provides SMS short message function, so it is commonly known as "short message cat", which is mainly used for short message alarm in computer room monitoring industry. Connect the SMS cat to the COM port of the host computer equipped with computer room monitoring software, and then the computer room monitoring software controls the LTE Modem to send alarm messages.
It can't work independently, and it needs to be realized by sending AT commands from the top software.
A similar product of LTE Modem is called LTE DTU. The difference between the two is that the former requires PC or control to send AT commands to realize Internet access or data forwarding, while there is a configuration tool that can set the IP address and port number of the server to forward serial data to the server. The two are very different in application.
