The correct answer is: B. Missed calls
Adjacent channel interference (ACI) is a type of interference that occurs when two or more signals are transmitted on adjacent channels. This can cause problems such as cross talk, missed calls, and blocked calls.
Cross talk is a type of interference that occurs when two or more signals are transmitted on the same channel. This can cause problems such as noise and distortion.
Missed calls occur when a call is not successfully connected due to interference. This can be caused by ACI, as well as other factors such as poor signal strength or network congestion.
Blocked calls occur when a call is not allowed to be connected due to interference. This can be caused by ACI, as well as other factors such as call forwarding or call barring.
Near-far effect is a type of interference that occurs when a mobile device is closer to a base station than other mobile devices. This can cause problems such as dropped calls and poor voice quality.
In conclusion, the correct answer is: B. Missed calls. ACI can cause a number of problems, including missed calls.
