Exhibit:

In this scenario the signal transmitted from the AP is reflected off a wall, resulting in multipathinterference at the client end (ClientA). Which of the following statements is true?()

A.The transmitted signal from the AP arrives at the client at slightly different times resulting inphase shifting
B.Multipath interference can be solved by using dual antennas
C.If signal 2 is close to 360 degrees out of phase with signal 1, the result is essentially zero signalor a dead spot in the WLAN
D.Multipath interference is less of an issue when using a DSSS technology because multipath isfrequency selective
E.If signal 1 is in phase with signal 2, the result is essentially zero signal or a dead spot in theWLAN
F.None of the other alternatives apply
