Executive Summary

This paper investigates the impact of small cells networks deployment in a typical residential environment. First the authors will present some aspects with regard to small cells coverage area when deployed in a macrocell sector area. Using the observations with regards to coverage they will further investigate the deployment of a residential femtocell network, implemented in closed access form. The paper proposes two algorithms in order to reduce the interference level at the macrocell user site, considering that the operator owns at least two carrier frequencies which will be used for both the macrocellular and femtocellular layers.
