While the deployment of femtocell in residential buildings has firmly positioned it as a major performance leap in wireless communications, its deployment in commercial buildings remains under-explored. In commercial building environments, the femtocell Base Station (FBS) placement planning is particularly challenging due to the impact of the building size, layout, structure, and wall/floor separation. In this paper, the authors study the problem of jointly optimizing FBS placement and power control in commercial building environments to prolong the battery life for mobile handsets. They first propose a mathematical model that captures the unique building features. Based on this model, they employ a set of novel transformation strategies to formulate the FBS placement problem as a Mixed-Integer Convex Program (MICP).
