(a) Coverage area is increased

(b) Signal paths are reduced

(c) Probability of collisions is increased

(d) Interference is reduced

The question was asked by my school teacher while I was bunking the class.

Best answer
The correct option is (c) Probability of collisions is increased

For explanation I would say: Smart antenna allows improved SNR so coverage area is also increased. The signal paths are reduced so the multi-path reduction, the transmitted RF energy is confined to a desired direction so interference is reduced. Probability of collisions is reduced and network capacity is increased.
