Think of a crowded room where everyone is trying to speak at once; Wi-Fi manages this chaos using a protocol called CSMA/CA, which ensures devices take turns to avoid collisions[6]. Before sending data, a device listens to the channel to see if it is clear[2][6]. If the airwaves are busy, it waits for a random period before checking again[2][6]. When too many devices compete for the same frequency, this waiting time increases, which is why you notice slower speeds in busy places like airports[1][3]. Newer Wi-Fi standards help by offering better efficiency and advanced features to handle these high-density environments more effectively[1][3].
