Question: In a cellular network with frequency reuse = 1, what is the primary purpose of conducting intra-frequency neighbor (cell) measurements for cells sharing the same carrier frequency as the serving cell?
Option 1: To optimize handover decisions and ensure seamless mobility support within the same frequency layer.
Option 2: To reduce interference between cells operating on different carrier frequencies.
Option 3: To enhance the security of data transmission across neighboring cells.
Option 4: To facilitate the deployment of new cells with different carrier frequencies.
Explanation: In a system with frequency reuse = 1, where all cells use the same carrier frequency, accurate intra-frequency neighbor cell measurements are crucial for ensuring good mobility support. This is because handovers occur more frequently within the same frequency layer, and precise measurements help in making informed handover decisions, thus maintaining seamless connectivity as users move between cells.
