Key Concepts & Definitions

  • Cell splitting: The process of subdividing a congested cell into smaller cells, each with its own base station, to increase system capacity without requiring additional spectrum. (Source: Dr. Hiba M Isam, 2024/2025)

  • Reduction of antenna height and transmitter power in smaller cells: As cells are subdivided, the antenna height and transmitter power are decreased to match the smaller cell radius, ensuring efficient coverage and minimizing interference. (Source: Dr. Hiba M Isam, 2024/2025)

  • Effect of cell radius reduction on number of cells required: When the radius of each cell is halved, approximately four times as many smaller cells are needed to cover the same area, since the coverage area of each cell is proportional to the square of its radius. (Source: Dr. Hiba M Isam, 2024/2025)

  • Transmit power adjustment to maintain signal-to-interference ratio: To ensure consistent signal quality after cell splitting, transmit power must be reduced so that received power at the new cell boundary remains equal to that of the original cell, maintaining the same signal-to-interference ratio. (Source: Dr. Hiba M Isam, 2024/2025)
