Question: When performing conformance tests for a device accessing a Next Generation Radio Access Network (NG-RAN), which type of system simulator is required?
Option 1: Universal System Simulator
Option 2: Evolved Universal System Simulator
Option 3: Next Generation System Simulator
Option 4: NB System Simulator
Explanation: When testing a device's interaction with a NG-RAN, a simulator that mimics the specific characteristics and interfaces of NG-RAN is necessary. The Next Generation System Simulator is designed for this purpose, ensuring conformance tests accurately reflect real-world NG-RAN interactions, which is crucial for reliable and efficient telecom network operations.
