Question: What is the primary reason for verifying that a User Equipment (UE)'s minimum transmit power at an active carrier is below a certain threshold (e.g., less than 50 dBm) in a cellular network?
Option 1: To ensure the UE can achieve maximum data transfer rates under all conditions.
Option 2: To prevent overheating of the UE, which could lead to reduced lifespan.
Option 3: To maintain compatibility with older network infrastructure designed for lower power transmissions.
Option 4: To minimize interference on other channels and preserve system capacity.
Explanation: The correct answer is Option 4 because if a UE's minimum transmit power is too high (e.g., above the specified threshold like 50 dBm), it can significantly increase interference to adjacent or nearby channels, decreasing overall system capacity due to increased resources needed for mitigation, reducing efficient multi-user support in wireless communication systems.
