Question: What is the maximum allowed cell re-selection delay in a GSM cell, considering all additional delays, and what is the minimum required rate of correct reselections during repeated tests?
Option 1: Less than 5.5 seconds + 2880 ms (identification time) + 640 ms (measurement time) + 1.9 s (BCCH time) + 10 ms (additional delay); Correct reselection rate: at least 90%
Option 2: Exactly 5.5 seconds + 2880 ms (identification time) only; Correct reselection rate: at least 80%
Option 3: Less than 1.9 s (BCCH time) only; Correct reselection rate: at least 95%
Option 4: More than 10 seconds total delay; Correct reselection rate: at least 90%
Explanation: The correct answer is Option 1 because it accurately sums up all the components of the cell re-selection delay. The total maximum delay would indeed be the sum of these components, plus the initial 5.5 seconds, and the question correctly identifies a minimum correct reselection rate of at least 90%, aligning with nuanced understanding of telecom network performance metrics under specified conditions.
