Question

A municipal warehouse sees unexpectedly weak links between an AP and vertically polarized clients despite short distance and clear LOS. Antenna documentation shows a horizontally polarized patch on the AP. What is the likely RF cause?

Accepted Answer

Antenna polarization mismatch between AP and clients can sharply reduce received signal despite short path length. — Mismatched polarization is like trying to high-five through a pane of glass at the wrong angle — lots of energy never couples. Fix orientation or antenna choice. Short distance doesn't erase a cross-pol hit.

Answer

Short distance always guarantees maximum MCS regardless of antenna orientation.

Answer

Polarization is irrelevant indoors because multipath cancels all polarization loss.

Answer

Weak links prove DFS CAC failure even on 2.4 GHz non-DFS channels.
