Question

What are co-channel cells?

(a) Cells having different base stations

(b) Cells using different frequency

(c) Cells using adjacent frequency

(d) Cells using same frequency

I have been asked this question in homework.

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

Answer 1

Correct option is (d) Cells using same frequency

To explain I would say: Due to frequency reuse concept, there are several cells that use the same set of frequencies. These cells are called co-channel cells. And the interference between these cells is called co-channel interference.
