4G modem is a kind of wireless terminal equipment which is specially used to convert serial port data into IP data or IP data into serial port data.It is widely used in meteorology, hydrology, water conservancy, geology and other fields.

The hardware of 4G modem is mainly composed of CPU control module, wireless communication module and power module.Its advantages are quick and flexible configuration, short construction period and low cost. And can be connected to the Internet with wide coverage,Has the good secrecy ability, the link forever on-line support, according to the current capacity charge, the user use cost is low.

The 4G modem is mainly used for wireless transmission of data.Through long-distance wireless data transmission, 4G modem has greatly increased the transmission distance of industrial equipment.And that long-distance transmission and management of the equipment are possible.

A 4G modem works by interfacing to a terminal device to obtain data,And transmits the data to the designated data center or device through the carrier network Lte Cat-4, Lte Cat-1 by radio.At the same time, the reverse data center can also send data or instructions to the 4G modem through the operator network.The 4G modem can then send data or instructions to the terminal device through the interface.

According to the communication mode, 4G modem usually adopts communication modes such as Lte Cat-4 and Lte Cat-1.Customers can choose the best communication mode according to the application scenario and the classification of interface types.The 4G modem usually supports RS485, RS232 and I/O interfaces, and the customer can select the appropriate interface type according to the front-end acquisition equipment.In addition, there is an embedded 4G modem, which is similar to the general 4G modem in function, but the main difference is that there is no shell.Is an embeddable motherboard that customers can integrate into their front-end integration devices.

4g lte modem has been widely used in power engineering, water conservancy projects, environmental protection, climate, transportation, freight logistics, industrial production and other industries.Industry. It provides assistance for the integration of information and industrial chains among various industries.And the development trend has gradually become the key technology for the application of the Internet of Things.

In practical applications, 4G LTE modems are usually used for wireless transmission of data.Its role is mainly through long-distance wireless data transmission, the transmission object is equipment and data center or equipment.The existence of 4G LTE modem has greatly increased the transmission distance of industrial equipment, enabling equipment to be transmitted and managed over long distances.

As a key technology in the field of Internet of Things, 4G LTE modem technology has a wide range of application scenarios.It can provide help for the integration of information and industrial chain among various industries.
