A macrocell is a cell in a mobile phone network that provides radio coverage served by a high power cellular base station (tower). High power implies higher amount of radiations are emitted. Generally, macrocells provide coverage larger than microcell. 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.
A microcell is a cell in a mobile phone network served by a low power cellular base station (tower), covering a limited area such as a mall, a hotel, or a transportation hub. A microcell is usually larger than a picocell, though the distinction is not always clear. A microcell uses power control to limit the radius of its coverage area.
Typically the range of a microcell is less than two kilometers wide, a picocell is 200 meters or less, and a femtocell is on the order of 10 meters.
In August 2012, the Union government has told Parliament that the exposure limit of radio frequency fields (base station emissions) will be brought down to one-tenth of the existing level from September 1. Microcells, Picocells and Femtocells are viewed as an alternative to current use Macrocells
