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 f

Channel selection is the process of choosing the optimal channel within a frequency band to minimize interference, not automatically moving clients between different frequency bands.

Near-field communication (NFC) is a short-range wireless technology used for data exchange between devices in close proximity, unrelated to Wi-Fi band management.

Propagation refers to how radio waves travel through a medium, which is a fundamental principle of wireless communication, not a feature for automatic client band management.

Band steering is a Wi-Fi technology implemented in access points that encourages dual-band clients to connect to the less congested or faster 5.0GHz band when feasible. It operates by temporarily ignoring client association requests on one band to prompt the client to try the other, optimizing client experience and balancing network load.
