細胞的概念:細胞分裂
- the new cell is called as microcell which has the smaller radius than the original cell
- increase the number of cells such that increase the capacity of a cellular system
- reduction of the antenna height and power
- system grows by replacing large cells with small cells
- in practice, not all cells are split in the same time
- different cell sizes will exist simultaneously
- R : decreasing, Q=D/R : unchanged
