Q:

Which of the following is mostly used to generate multiple fixed beams by augmentation in specific orders?

A) Switched Beam array B) Range gates
C) Conical Scanning D) FMCW radar
 
Answer & Explanation Answer: A) Switched Beam array

Explanation: Switched beam is used for forming multi rays in specific orders. Range gates and delay line cancellers find applications in MTI radars to get the accurate target information. In conical scanning continuous scanning is performed by beam.

Q:

Which of the following is used to distinguish the selected signal and the multipath signal in smart antenna architecture?

A) DSP procedure B) Switched beam array
C) Range gates D) Delay Cancellers
 
Answer & Explanation Answer: A) DSP procedure

Explanation: Adaptive array system change the sign patterns with respective to RF settings. DSP procedure is used to differentiate the selected signal from the multipath signals. Switched beam is used for forming multi rays in specific orders. Range gates and delay line cancellers find applications in MTI radars to get the accurate target information.

Q:

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

A) Range is increased B) Secured transmission
C) Design of trans-receiver is simple D) Probability of collisions is reduced
 
Answer & Explanation Answer: C) Design of trans-receiver is simple

Explanation: The design of trans-receiver for a smart antennas is quite complex than a traditional base station trans-receiver. Secured transmission, increase in range, reduction in probability of collisions is benefits of smart antenna.

Q:

Which of the following statements is false regarding smart antenna for 802.11 applications?

A) Coverage area is increased B) Signal paths are reduced
C) Probability of collisions is increased D) Interference is reduced
 
Answer & Explanation Answer: C) Probability of collisions is increased

Explanation: 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.

Q:

The Upper ray is stronger than the lower ray and is mostly preferred for communication.

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

Explanation: The Upper ray is weaker than the lower ray in terms of energy contents and it spreads more in the electron density region compared to the lower ray. So the lower ray is mostly preferred for communication.

Q:

Which of the following propagation is used when the receiver is beyond the skip distance?

A) Single hop B) Single hop multi layer
C) Multi hop D) Ground wave
 
Answer & Explanation Answer: C) Multi hop

Explanation: When the receiver is beyond the skip distance, single hop is prevented from reaching the receiver. It requires more than one hop to travel to the desired receiver. So Multi Hop propagation with single or multi layer is used.

Q:

The propagation of wave from transmitter to receiver by touching ground in between them and goes through different layers is called _____

A) Multi-hop single layer B) Single hop multi layer
C) Multi hop multi layer D) Single hop single layer
 
Answer & Explanation Answer: C) Multi hop multi layer

Explanation: Multi hopping means the wave touches the ground once or more than once while travelling from transmitter to receiver. If it propagates through the multiple layers then it is called multi-hop multi layer. In single hopping the wave doesn’t touches the ground.
