ADVANTAGES OF CELLULAR SYSTEMS WITH MINIATURE CELLS
1. Higher capacity: If SDM is employed it allows frequency reuse. If two transmitter is far away then frequency reuse is possible. If the cell is small, then more number of users are allowed.
2. Less transmission power: A mobile or hand held devices needs more power. The devices which are closer to Base station needs less power for transmission.
3. Local interference: If there is a large distance between sender and receiver then there will be more interference. If the cell size is small then mobile station and base station need to deal with local interference.
4. Robustness: The cellular systems are decentralized. If one antenna fails it will affect small region.
