Question: In a conformance test for Radio transmission and reception (TDD) with a 1.28 Mcps option, what are the pass criteria based on the total number of successful tests and the associated confidence level?
Option 1: More than 80% success rate with a confidence level of 90%
Option 2: Exactly 95% success rate with a confidence level of 99%
Option 3: More than 90% success rate with a confidence level of 95%
Option 4: At least 85% success rate with a confidence level of 92%
Explanation: This question assesses understanding of test conformance criteria in telecom standards. Option 3 is correct because it aligns with the specified pass criteria for such tests, emphasizing both a high success rate (>90%) and a robust confidence level (95%). This ensures that devices meet stringent performance benchmarks, crucial for reliable wireless communications. The incorrect options (1, 2, and 4) either lower the success rate or alter the confidence level, potentially compromising network reliability and user experience.
