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
