Question: What is a key consideration for determining the sufficient number of samples for accurate Over The Air (OTA) antenna performance measurements in User Equipment (UE)/Mobile Station (MS)?
Option 1: To ensure compatibility with all existing base station configurations
Option 2: The limited size of the radiating object, which restricts how much the gain pattern can change versus angle
Option 3: To minimize the overall cost of the testing equipment for conformance testing
Option 4: To guarantee real-time measurement feedback for immediate antenna adjustments
Explanation: The correct answer highlights a fundamental principle in OTA antenna performance measurements. The physical constraints of the radiating object (e.g., its size) inherently limit the variability of the gain pattern across different angles, allowing for accurate representation with a finite number of samples, ensuring efficient conformance testing.
