If an 802.11 RF transmission reaches a receiving antenna simultaneously by direct and indirect
(reflected) paths, what effect will the reflected signal have on the signal that took the direct line-ofsight path?

A.
The direct signal will only be received if the reflected signal is more than 180 degrees out of
phase.

B.
The direct signal cannot be received if the indirect signal is less than 90 degrees out-of-phase.

C.
The signals will be distorted if the indirect signal arrives simultaneously at the receiver, but 90
degrees out-of-phase.

D.
If the signals are in-phase, they will combine together, cancel one another out, and create a
null.
