Industrial routers have a wide range of application scenarios, from convenient life to sustainable development, from assisting in office to assisting in the construction of smart cities, industrial routers can remotely monitor the equipment status without personal presence, which is simple and fast. Industrial-grade wireless router products have been widely used in finance, water conservancy, envi···
NB-IoT and LoRa are both representatives of the field of low-power wide area networks. As representatives of the field of low-power wide area networks, both NB-IoT and LoRa are long-distance transmission technologies and are hard to distinguish. Then NB-IoT and LoRa are very strong. Who is the future trend of the Internet of Things? Let's take a look at the specific content.
Compared with 4G, the security of Wifi network is self-evident-Wifi internal network devices do not have independent public network IP, so the attacker must first break through the router to enter the internal network, and some do not connect to the external network. The Wifi network provided a very safe wireless network environment for the intranet.
Data terminal (4G DTU) access: 4G users can choose CMNET and APN to access the network. CMNET is usually used for public users, and APN is for industry users, usually in a group. Users need to set a user name and password, which is more secure good. In addition, APN users can apply for binding fixed IP addresses of mobile intranets.
Industrial router is a kind of use public wireless network to provide users with wireless data transmission function. How to choose a good industrial router is not that simple, so what performance does a good industrial router have? Let's take a look at the seven core performances of industrial routers.
Smart gateway, also called industrial IoT smart gateway, wireless data collection gateway, communication collection gateway, wireless gateway, industrial communication gateway, wireless sensor management host, industrial Ethernet serial port smart gateway, RS485 serial port Modbus RTU smart gateway, belongs to wireless sensor Internet product.
Cellular 4G industrial routers are compatible with 4G/3G/2.5G networks at the same time, realizing support for multiple frequency bands across the entire network, so that industry customers no longer need to purchase multiple ordinary single-mode routers to adapt to the non-network environment, so what are the features of the full Netcom router Woolen cloth?
The wireless communication module enables all kinds of terminal devices to have the ability to transmit information on the Internet, and is the information portal for all kinds of intelligent terminals to access the Internet of Things. It is the key link that connects the perception layer and the network layer of the Internet of Things. The device data generated by all the terminals of the Interne···
4G RTU integrates traditional industrial RTU and full Netcom/4G/3G/5G data transmission functions into one, realizing comprehensive functions such as collection, counting, control, storage, alarm and transmission. It is also compatible with the data transmission function of the full Netcom/4G/3G/5G IP MODEM.
Narrowband Internet of Things (NB-IoT) technology is widely used in agriculture, industry, government and life. So what is the architecture diagram of Narrowband Internet of Things (NB-IoT) technology? A typical NB-IoT architecture has three layers, which are Perception layer, network layer, application layer.
