NB-IoT user terminals can work in power saving mode to reduce power consumption and prolong battery life. When the user terminal works in the power saving mode, similar to the shutdown of the device, it seems to be disconnected from the network, but the user terminal is still registered in the network and does not need to re-attach or re-establish a packet data network (Packet Data Network) connec···

As the most promising low-power wide-area communication technology, LoRa has been used in all walks of life. LoRa uses linear frequency modulation spread spectrum modulation technology, which maintains low power consumption, significantly increases communication distance and network efficiency, and eliminates interference, so that even if the same frequency is used for simultaneous transmission, t···

4G industrial routers are more used in industry,naturally the requirements of the product are higher, so the price of 4G industrial routers and general ordinary routers are also different, so what factors affect the price of 4g industrial routers? How to choose a cost-effective 4G industrial router for yourself?

Industrial wireless router and industrial DTU are both to achieve wireless network data transmission function, but in fact, the difference between the two is still very big, the router is connected to the Internet in the various local area networks, wide area networks of communication equipment; and DTU is a digital transmission terminal equipment, both are wireless communication equipment, but ea···

The high stability of industrial-grade 4G routers when transmitting and receiving data is one of its main advantages. It uses high-performance industrial-grade wireless modules and industrial-grade high-stable and high-precision components, which can make it resistant to harsh outdoor environments without interruption or loss of data transmission.

The maximum distance covered by a general wireless router is usually 100 meters to 300 meters. However, after testing, the wireless signal distance of many wireless 4G routers is difficult to reach the theoretical value. So what are the factors that affect the coverage of industrial 4G routers? Industrial 4G routers How to adjust coverage?

Industrial 4G routers are used for interactive transmission of remote big data, and can be used in a variety of complex environments that are subject to high temperature and severe cold, providing reliable networking and stable communication for unattended systems. So what fields are industrial 4G routers generally used in?

Compared with GPRS, the biggest feature of NB-IoT is low power consumption. In addition to the relatively low transmission rate of NB-IoT itself, NB-IoT introduces eDRX power saving technology and PSM power saving mode, which is also the main reason for power saving.

NB-IoT is a new narrowband cellular communication LPWAN (Low Power Wide Area Network) technology that can help us solve this problem.

The serial server is a serial port to Ethernet module plus a shell, which has the function of electromagnetic isolation.
