Numerous vendors implemented a feature in routers and access points that allows for automatically moving wireless clients between 2.4GHz and 5.0GHz frequencies based on user density and the distance from the wireless equipment. Which of the following describes this feature?

Channel selection refers to the process of choosing specific channels within a frequency band to minimize interference and optimize signal quality. While important for network performance, it does not involve moving clients between frequency bands, which is the primary function of band steering.

Near-field communication (NFC) is a short-range wireless technology allowing devices to communicate when they are within close proximity. It is unrelated to the frequency management of wireless networks and does not involve steering clients between different frequency bands.

Propagation refers to how radio signals travel through the environment, affected by various factors such as obstacles and distance. Although it plays a role in wireless communication, propagation does not pertain to the feature of actively managing client connections between different frequency bands based on usage and distance.
