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
