Answer 1

Right option is (a) Design of trans-receiver

To explain: Design of trans-receiver is a complex when compared to the traditional base station trans-receivers because separate trans-receiver chains are needed for each array elements. Probability of collision reduction, focusing on desired direction is the benefits of smart antenna.
