← TechnologyWhich outcome occurs when high Carrier-to-Interference Ratio (CIR) signal is sustained in wireless communication systems?
A)Increased modulation order is enabled✓
B)Lower signal bandwidth is achieved
C)Reduced transmission power is required
D)Increased interference spread occurs
💡 Explanation
Higher CIR enables advanced modulation techniques like QAM because a stronger signal reduces bit errors; therefore, a higher modulation order is utilized, rather than being limited, thereby requiring additional bandwidth for lower transmission power.
