Frequency Reuse: The design process of selecting and allocating RF channel group for all of the cellular base station within a cellular system is known as frequency reuse.
Advantages:
Higher capacity
• More frequent resource utilization increases the capacity
Less transmission power
• Reduced cell sizes, less power needed to cover the cell area
• Relaxed power amplifier specs at base stations
• Longer life-time for mobile station batteries
Localized interference
• Due to smaller service areas of cells, interference is as well localized to a smaller area
Robustness
• In case that one cell is down, overlapping of cells guarantees that a mobile is able to get connected through other base stations
No technological challenges in deployment
• Major problems related to minimizing the implementation and operational expenses of the system
• Technological challenges related to capacity improvement methods.
