Description

technical field [0001] The present invention relates to the technical field of wireless sensor networks, in particular to a device, method and system for detecting the category of wireless co-frequency signals based on packet error rate. Background technique [0002] With the development of wireless networks and the Internet of Things, especially some short-distance wireless co-frequency networks will be deployed in the same environment, such as smart buildings, agricultural Internet of Things and other application systems. ZigBee, Bluetooth, WiFi and RFID all work on the ISM2.4GHz frequency band. The ISM frequency band is a free global frequency band. In the same environment, multiple wireless signals using the same frequency band or similar frequency bands will cause interference. For those with low power, the data Devices that transmit slowly will cause delays, data loss, or even wrong data, etc., especially for those fire equipment and alarm devices that use ZigBee commu...
