big data can be said to be a technology trend that complements and multiplies with the Internet of Things. In agriculture, the Internet of Things plays a role in precise control and greatly improving production efficiency, making agriculture, fishery and animal husbandry reach an unprecedented level of refinement. On the other hand, the biggest role of big data in agriculture, fishery and animal h···

Among them, sensors (temperature sensor, humidity sensor, PH value sensor, illuminance sensor, CO2 sensor) are the key components of the agricultural Internet of Things.

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?
