LoRa networking:The LoRaWAN network architecture is a typical star topology. In this network architecture, the LoRa gateway is a transparent transmission relay, connecting terminal devices and the back-end central server. The terminal device uses a single hop to communicate with one or more gateways. All nodes communicate with the gateway in both directions.

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.

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···
