Question: In low-density areas, what is the minimum downlink (DL) user throughput requirement supported by the 5G system at the edge of its extreme long-range coverage (up to 100 km)?
Option 1: 100 kbit/s
Option 2: 500 kbit/s
Option 3: 5 Mbit/s
Option 4: 1 Mbit/s
Explanation: This answer is correct because, according to the service requirements for the 5G system, specifically in scenarios of extreme long-range coverage (up to 100 km) in low-density areas, the 5G system must ensure a minimum user throughput of 1 Mbit/s on the downlink (DL) at the edge of this extended coverage. This requirement highlights the system's capability to provide reliable, albeit minimal, broadband connectivity even in very remote or sparsely populated regions.
