The antennas for macrocells are mounted on ground-based masts, rooftops and other existing structures, at a height that provides a clear view over the surrounding buildings and terrain.
Macrocell base stations have power outputs of typically tens of watts.
[1] The term macrocell is used to describe the widest range of cell sizes.
Picocells are used for areas smaller than microcells, such as a large office, a mall, or train station.
Currently the smallest area of coverage that can be implemented with a femtocell is a home or small office.
