The signal coverage of 4g industrial routers will be affected by resources, media, space, layout, structure, water, carriers, concrete objects (walls, metal objects), etc. In the normal situation without obstruction, the more open the space is. The more the 4g industrial router signal coverage will be wider.

As we all know, at first the data was a simple process quantity of analog signal output, and then the instrument interface was RS232 interface, so that point-to-point communication can be realized, but this way cannot realize the networking function, and then the emergence of RS485 solves this problem. Therefore, this article introduces the RS485 interface in detail.

Generally speaking, 4G industrial routers are suitable for public areas, such as vending machines, lottery machines, coupon printing machines, advertising machines, smart express boxes, etc.

4G industrial routers have the following differences from traditional home routers. The following are divided into 10 points to explain the specific differences:

The 4G industrial router is a high-speed industrial Internet of Things router, compatible with 4G/3G/2G networks, and can use public LTE networks to form a high-speed and stable wireless transmission network.

DTU wireless data transmission terminal is a kind of wireless data transmission terminal equipment with strong anti-interference ability, powerful function, convenient use, low operating cost and low cost. It adopts GPRS/4 G/NB-IoT communication technology and makes full use of the existing network. resource. So, what are the benefits of doing this?

The full Chinese name of Narrow Band Internet of Things: Narrow Band Internet of Things is what we call NB-IOT, which is mainly based on LTE technology (3GPP Release 13).

At present, DTU has a wide range of applications in industry. It mainly solves the problem of transparent transmission of data between serial devices and remote servers when there is no network outdoors, such as in the fields of electricity, energy, transportation, water affairs, and agriculture.

Wireless DTU is a wireless communication device that performs two-way transparent transmission through a wireless communication network. Currently, wireless communication networks include GPRS, 4G, NB-IOT, LORA, and WIFI. Each wireless communication method has its advantages and application scenarios. The difference, customers can Choose the best communication method for your own application scena···

When DTU technology is adopted in various fields, the efficiency is greatly improved, and more and more fields begin to have a "favorite" for DTU technology.Players active in the mass market have 3G DTU/4G DTU/GPRS DTU series related products.
