Q:

Which of the following statement regarding smart antenna is false?

A) Design of transceiver is complex B) Smart antennas is more directive
C) Smart antenna is more expensive D) Numeric processors and control systems are not needed in smart antennas
 
Answer & Explanation Answer: D) Numeric processors and control systems are not needed in smart antennas

Explanation: Compared to the traditional base station trans-receivers, design of trans-receiver is a complex because there is a need of separate trans-receiver chains for each array elements. Smart antennas are more directive and costly. The base stations need very powerful numeric processors and control systems.

Q:

Which of the following is the drawback of smart antenna?

A) Design of trans-receiver B) Spacing between base stations
C) Probability of collisions being reduced D) Focused to an intended direction
 
Answer & Explanation Answer: A) Design of trans-receiver

Explanation: 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.

Q:

Which of the following is benefit of smart antenna?

A) It is easy to tap the connection by the intruder apart from the user B) Co-Channel interference is less compared to the Omni-directional
C) Design of Trans-receiver is complex D) It cannot be used for location-specific services
 
Answer & Explanation Answer: B) Co-Channel interference is less compared to the Omni-directional

Explanation: The spatial detection nature of the smart antenna enables for location specific services. Probability of collisions is reduced so the inference is also reduced in smart antennas. Thus the Signal to interference (SIR) increases in this. Smart antennas provide security so it is difficult for the intruder to get the user connection.

Q:

Which of the following suffers the co-channel interference most?

A) Smart antennas B) Sectored antennas
C) Omni-directional D) Both Smart antenna and Omni-direction
 
Answer & Explanation Answer: C) Omni-directional

Explanation: Omni-directional suffers more co-channel interference compared to the sectored and smart antennas. Probability of collisions is reduced so the inference is also reduced in smart antennas. Thus, the Signal to interference (SIR) increases.

Q:

In Smart antennas, signal to interference ratio is low.

A) True B) False
 
Answer & Explanation Answer: B) False

Explanation: Probability of collisions is reduced so the inference is also reduced in smart antennas. Thus the Signal to interference (SIR) increases in this by increasing the signal strength and reducing the interference.

Q:

Which of the following is not the benefit of smart antenna?

A) It increases the SIR B) It decreases the SIR
C) It increases the SNR D) Probability of collisions is reduced
 
Answer & Explanation Answer: B) It decreases the SIR

Explanation: Probability of collisions is reduced so the inference is also reduced in smart antennas. Thus the Signal to interference (SIR) increases in this. The SNR is also high as the multipath fading is also reduced n diversity type system.

Q:

In which of the following type of smart antenna, the performance of the multi-channel fading is limited?

A) Diversity system B) Omni-directional system
C) Sectored system D) Directional system
 
Answer & Explanation Answer: A) Diversity system

Explanation: In Diversity system, multi-path fading, co-channel interference, delay spread impairments are greatly reduced in smart antennas. Directional system uses sectored antennas reference to provide the energy to intended direction.
