'ABSTRACT Technically, mobile handsets connect to mobile operator networks via base stations located at the roof top of buildings. These base stations operate at different frequency bands depending on two main criteria: location of the area to be planned and applied technology (2G/3G/4G). High frequency bands suffer from poor indoor coverage due to increased path loss. To overcome indoor coverage problem, operators have installed distributed antenna systems (D.A.S) with signal boosters. Newly implemented solution consists of deploying Femto Access Points (FAPs). Since customers tend to deploy FAPs in arbitrary ways, they don't benefit from their full coverage and capacity. Therefore there is a need to optimize FAPs deployment in terms of number and position. We had developed a planning tool "FAP planner V1.0" using Matlab that simulates FAP coverage in indoor environments according to: o FAP characteristics (Transmitted power, supported users, maximum coverage range) o Different propagation models available in literature We had used this tool to predict 3G FAPs coverage in CIU-Haspolat Science and Technology Building. Taking into consideration the values predicted by Touch (2nd mobile interim company in Lebanon), who have worked on iBwave software that applies the accurate ray tracing model to predict indoor coverage for a basement in Beirut Arab University.'
