Question

For a cellular system, if there are N cells and each cell is allocated k channel. What is the total number of available radio channels, S?

(a) S=k*N

(b) S=k/N

(c) S=N/k

(d) S=k^N

This question was posed to me in class test.

I'm obligated to ask this question of Frequency Reuse topic in section The Cellular Concept – System Design Fundamentals of Wireless/Mobile

Answer 1

Correct option is (a) S=k*N

Best explanation: If there is a cellular system with total of S duplex channels. Each cell is allocated a group of k channels and there are total N cells in the system, S channels are divide among N cells into unique and disjoint channel groups. Therefore, total number of radio channel is the product of total number of cells in the system (N) and number of channel allocated to each cell (k).
