Although femtocell deployments in residential buildings have been increasingly prevalent, femtocell deployment in commercial building environments remains in its infancy. One of the main challenges lies in the Femtocell Base Stations (FBS) placement problem, which is complicated by the buildings' size, layout, structure, and floor/wall separations. In this paper, the authors investigate a joint FBS placement and power control optimization problem in commercial buildings with the aim to prolong mobile handsets' battery lives. They first construct a mathematical model that takes into account the unique Floor Attenuation Factor (FAF) and FBS installation restrictions in building environments.
