Question

Which of the following is not a source of interference?

(a) Base station in a different cluster

(b) Another mobile in same cell

(c) A call in progress in neighbouring cell

(d) Any BS operating on same frequency

This question was addressed to me in class test.

This is a very interesting question from Interference and System Capacity in chapter The Cellular Concept – System Design Fundamentals of Wireless/Mobile

Answer 1

Right answer is (a) Base station in a different cluster

The explanation is: Interference is a major limiting factor in the performance of cellular radio systems. Sources of interference includes another mobile in the same cell, a call in progress in neighbouring cell, other base stations operating in the same frequency band, or any non-cellular system which inadvertently leaks energy into the cellular frequency band.
