CWISA-102 · Question #3
What is the benefit of using SINR as opposed to SNR to reference signal quality at a receiver?
The correct answer is A. SINR includes interference as well as the noise floor. SNR (Signal-to-Noise Ratio): Measures the power of the desired signal relative to background SINR (Signal-to-Interference-plus-Noise Ratio): Considers both background noise and interference from other signals operating on the same frequency. Practical Importance: SINR is a more…
Question
What is the benefit of using SINR as opposed to SNR to reference signal quality at a receiver?
Options
- ASINR includes interference as well as the noise floor
- BSNR excludes the noise floor, which skews the results
- CSINR excludes interference and only measures the noise floor
- DSNR includes interference measurements that skew the results

Explanation
SNR (Signal-to-Noise Ratio): Measures the power of the desired signal relative to background SINR (Signal-to-Interference-plus-Noise Ratio): Considers both background noise and interference from other signals operating on the same frequency. Practical Importance: SINR is a more realistic indicator of real-world signal quality in wireless environments where interference is a significant factor.
