D. No signals are relayed from one client to another client.
Answer: C
NO.5 Which description best describes upfade in a multipath environment?
A. In this situation, multiple signal paths are not sent at exactly the same time. The receiver receives
a positive crest on the primary signal and a negative crest on the secondary signal.
