diversity antennas. An AP with diversity antennas continuously samples incoming signals, choosing the input source (antenna and receiver) with the best signal, then using the chosen antenna for the next transmission.

As a result, the AP may receive both the primary signal and one or more reflections of that same signal. Diversity algorithms let the AP use the best signal at any given time, adjusting automatically for changing environmental conditions.
