What term describes the process when a station adjusts its data rate as it moves farther from the AP?

The correct term for the process when a station adjusts its data rate as it moves farther away from the access point (AP) is dynamic rate switching. This process is crucial in wireless communication because the quality of the signal can vary significantly depending on the distance between the client and the AP, as well as other environmental factors like obstacles and interference.

As the signal strength decreases—often indicated by a reduction in the received Signal-to-Noise Ratio (SNR)—the wireless client dynamically negotiates a lower data rate to maintain a reliable connection. This method allows for sustained communication by tailoring the data rate to current conditions, thereby reducing the likelihood of packet loss and ensuring that the link remains usable even in conditions where the signal quality diminishes.

Dynamic rate switching is vital to optimizing network performance in real-time, enabling faster rates when the signal quality is strong and shifting to lower rates without dropping the connection when the signal is weak. This adaptability is essential in mobile environments where devices frequently change their location relative to the AP.
