Question: In a 5G system, what is a key aspect of supporting a 'fully connected society' as described in service requirements?
Option 1: Providing ultra-low latency only in urban areas for enhanced mobile broadband.
Option 2: Ensuring network access everywhere, including remote rural areas and at sea, for both human and machine communications.
Option 3: Focusing solely on increasing the overall network capacity to accommodate more users.
Option 4: Implementing advanced security measures for data transmission over short distances.
Explanation: Supporting a 'fully connected society' implies ensuring ubiquitous connectivity. This includes extending network access to all areas, regardless of how remote (e.g., rural areas or at sea), and catering not just to human communication but also to machine-to-machine (M2M) communications, which is crucial for IoT applications.
