4G industrial router VPN technology is one of the important technologies of routers, so what is the use of 4G industrial router VPN?

The Internet of Things is based on the computer Internet, using RFID, wireless data communication and other technologies to construct an "Internet of Things" covering everything in the world. In this network, items (commodities) are able to "communicate" with each other without human intervention. Its essence is to use radio frequency automatic identification (RFID) technology to realize the autom···

Five key technologies of the Internet of Things The foundation of the future Internet of Things industry Long-range wireless network communication technology

the WiFi password setting of any industrial-grade wireless router should pay attention to security. Remember that the password cannot be too simple, which is prone to leakage.

The cellular-based Narrow Band Internet of Things (NB-IoT) has become an important branch of the Internet of Everything. NB-IoT is built on a cellular network and only consumes about 180KHz of bandwidth, and can be directly deployed on a GSM network, UMTS network or LTE network to reduce deployment costs and achieve smooth upgrades.

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.
