Advantages of cellular system:

1. Higher capacity-Smaller the size of the cell more the number of concurrent users i.e. huge cells do not allow for more concurrent users.

2. Less transmission power-Huge cells require a greater transmission power than small cells.

3. Local interference only-For huge cells there are a number of interfering signals, while for small cells there is limited interference only.

4. Robustness-As cellular systems are decentralized, they are more robust against the failure of single components.
