Question: In a 5G system, which of the following factors contributing to overall service latency is LEAST dependent on the 5G system's internal architecture?
Option 1: Delay on the radio interface
Option 2: Transmission within the 5G system
Option 3: Data processing at a server outside the 5G system
Option 4: Interconnection protocols between 5G systems and external services
Explanation: While overall latency in a 5G system is crucial, factors like radio interface delay (Option 1) and transmission within the 5G system (Option 2) are directly influenced by the 5G system's internal architecture. Interconnection protocols (Option 4) also depend on the 5G system's setup for external communications. However, data processing at an external server (Option 3) is primarily dependent on the server's capabilities and load, rather than the 5G system's internal workings, making it the least dependent factor.
