When plugged into a USB port, the dongle establishes a connection and communicates with your operating system. It contains a built-in radio transmitter and receiver that scans for available WiFi networks, authenticates the connection, and transmits/receives data using IEEE 802.11 wireless standards. Most modern dongles are “plug-and-play,” requiring minimal setup or driver installation.
