4G LTE modem is a kind of wireless terminal equipment which is specially used to convert serial port data into IP data or convert IP data into serial port data and transmit them through wireless communication network.

The 4G LTE modem solution meets the interconnection needs of various equipment scenarios, has strong compatibility and adaptability, and is widely used in the industry. 4G LTE modem has been used in industrial Internet of Things, fresh air purification, power industry and smart retail, helping customers realize the transformation from stand-alone equipment to networked equipment and realize equipment interconnection.The existence of 4G LTE modem is like a computer network card to realize the Internet of things.

For example:

When I was at home, I found that the big bucket of water placed in the water dispenser was gone, so I picked up my mobile phone, searched for the contact information of the "water delivery person", dialed the other party's phone, and told me that I needed a bucket of water. Hang up the phone, 15 minutes later, the big bucket of water arrived.

This is a piece of life that is easy to understand. If we compare it to the way 4G LTE modem works, it will be easier for you to understand what 4G LTE modem is.

"There is no big bucket of water, we need a big bucket of water." This is a demand, similar to a signal in the Internet of Things world.

"My mobile phone" and "water man's mobile phone" are two terminal devices that can send and receive signals to each other.

In the process of making phone calls to transmit signals, "China Mobile", as a data converter and signal disseminator, completes information exchange in the middle, which is the role of "4G LTE modem" in the Internet of Things world.

The 4G LTE modem is widely used as a communication device. In different applications, the IP terminal and port number of the data center and the baud rate of the serial port are different. Therefore, the 4G LTE modem supports parameter configuration and stores the configured parameters in an internal persistent storage device, usually flash memory. Once powered on, the 4G LTE modem will automatically operate according to the set parameters.
