In summary, the application of NB-IoT is divided into four fields: public service field, personal field, industrial manufacturing field, new technology and new business field. Among them, smart metering of water, electricity and gas meters, public parking management, and environmental monitoring are listed as entry points in the field of public services.

NB-IoT is an emerging Internet of Things technology, which has attracted attention because of its low power consumption, stable connection, low cost, and excellent architecture optimization. Using the license frequency band, three deployment methods such as in-band, guardband or independent carrier can be adopted. , Coexist with the existing network.

The data transfer unit DTU (Data Transfer unit) is a wireless terminal device specially used to convert serial data to IP data or convert IP data to serial data to be transmitted through a wireless communication network. The entire Netcom DTU covers the entire network, and the Internet of Things gateway is also Can carry out data transmission, so what is the difference between Netcom DTU and IoT g···

The Internet of Things based on LTE technology is a brand-new Internet of Things technology that brings many advantages to the application of the Internet of Things, including extensive and deep network coverage, predictable service quality, highly reliable and stable end-to-end security and global standard support The seamless interoperability will bring more opportunities for the Internet of Thi···

Industrial gateways are also called IoT gateways. As the link between the perception layer and the network layer, the IoT gateway can realize the protocol conversion between perception networks and communication networks, as well as different types of perception networks, which can realize wide-area interconnection or realization Local area interconnection. Today we will take a look at the key tec···

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 consumes only about 180KHz of bandwidth. It can be directly deployed on GSM networks and UMTS networks. Or LTE network to reduce deployment costs and achieve smooth upgrades. These issues of the NB-IoT protocol of the Narrowband Internet of ···

NB-IoT (Narrowband Internet of Thing) uses ultra-narrowband, repeated transmission, streamlined network protocols and other designs to sacrifice a certain rate, delay, and mobility performance to obtain the carrying capacity for LWPA Internet of Things. As a new narrowband cellular communication LPWAN (Low Power Wide Area Network) solution, NB-IoT will bring huge changes and innovations to the Int···

The basic function of 4G industrial gateway is mainly responsible for the connection of two heterogeneous networks. This is especially common in industrial IoT scenarios, because sensor networks often use electrical signals and signals that are completely different from the general network layer (long-distance transmission network). protocol.

IoT gateway edge computing is the local calculation and analysis performed on the side close to the data source near the terminal device. Essentially, both edge computing and cloud computing were born to deal with data computing problems, but they are implemented in different ways. Cloud computing is to gather data together for calculation, while edge computing is to perform calculations on the te···

Smart gateway is 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 smart gateway, Modbus RTU smart gateway.
