Which effect is responsible for a strong transmitter overpowering a weak signal?

• a) Doppler Effect
  

• b) Near-Far Effect
  

• c) Faraday Effect
  

• d) Shannon Effect

What is desensitization in wireless communication?

• a) A method to boost weak signals
  

• b) A phenomenon where a strong nearby transmitter overpowers a weak signal
  

• c) A type of noise reduction technique
  

• d) A way to improve call quality

(a)   interference happens when signals from nearby frequencies interfere with each other.

When two cells use the same frequency, it results in (a)   interference.

The (a)   mobile refers to a device that transmits with lower power or is farther from a base station.

Which of the following can cause interference in a cellular network?

• a) Other mobiles in the same cell
  

• b) Calls in neighboring cells
  

• c) Non-cellular systems leaking energy
  

• d) All of the above

How does co-channel interference affect system capacity?

• a) Increases the number of calls that can be handled
  

• b) Reduces the number of users a network can support
  

• c) Improves voice clarity
  

• d) Has no impact on capacity

Which factor contributes to the near-far effect in mobile communication?

• a) High network congestion
  

• b) Uneven power levels among users
  

• c) Low-frequency signals
  

• d) Large antenna sizes

What does the Co-Channel Reuse Ratio (Q) represent?

• a) The number of channels used in a cell
  

• b) The distance between co-channel cells divided by the cell radius
  

• c) The power level of a strong transmitter
  

• d) The capacity of a mobile network

In cellular networks, (a)   planning is essential to minimize interference and maximize capacity.
