Question: In E-UTRAN, what is the primary reason for utilizing diverse methods and techniques for synchronization at an eNodeB (eNB)?
Option 1: To reduce the number of logical ports required for timing inputs
Option 2: To enhance security by complicating synchronization protocols
Option 3: Because no single method can cover all potential E-UTRAN application scenarios
Option 4: To decrease the cost of implementing synchronization in rural areas
Explanation: The correct answer highlights the key challenge in E-UTRAN synchronization - the diversity of applications and scenarios, each with unique requirements that cannot be met by a one-size-fits-all approach. This necessitates using various methods and techniques to ensure flexibility and reliability across all E-UTRAN applications.
