Dynamic Rate Switching (DRS)

Automatic adjustment of a client's data rate as signal quality changes; also called rate shifting.

Definition

As a client moves away from an AP or SNR drops, the radio shifts to lower, more robust data rates. Moving closer allows higher rates. Each vendor implements its own rate adaptation algorithm.

Exam tip

DRS creates concentric zones of decreasing data rates around an AP.
