Question

In a cellular network with a 7-cell reuse pattern and total available spectrum of 25 MHz, each cell gets spectrum of approximately:

A
25 MHz
B
3.57 MHz
Correct
C
175 MHz
D
0.5 MHz

Correct answer

3.57 MHz

Explanation

With N=7 reuse pattern, each cell uses Total/N = 25/7 ≈ 3.57 MHz. A smaller reuse factor N increases per-cell spectrum (more capacity) but requires better signal separation. Modern networks use fractional frequency reuse and interference coordination for N=1 (each cell uses all spectrum) with sophisticated interference management.
