The traditional analog walkie-talkie is a communication mode in which voice, signaling, and signals aremodulated to the transmission frequency of the

LoRaWAN is a set of communication protocol and system architecture designed for LoRa long-distance communication network. A LoRaWAN network architecture includes four parts: node, gateway, and Raspberry Pi. Among them, the nodes are generally controlled by sensors or switches to realize remote sensor data collection or switch control applications.

Most wireless chips on the market can only work on one frequency at a time. If a single wireless device needs to receive multiple frequency signals, the device can only be controlled to continuously switch frequencies and detect signals on each working frequency band. This method is not only time-consuming and complicated, but also because the device cannot receive signals of the other frequency when the device is in one of the frequencies, it is easy to cause data loss.
