Question

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?

Options

AChannel selection
BNear-field communication
CPropagation
DBand steering

Explanation

The feature that automatically directs wireless clients between 2.4GHz and 5.0GHz bands based on network conditions is known as band steering. This optimizes client performance and network efficiency by leveraging both frequency bands.

Common mistakes.

A. 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.
B. 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.
C. 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.

Concept tested. Wi-Fi band steering technology
