This paper is to show that the indoor downlink capacity and energy efficiency can be significantly improved by optimising the indoor location of femtocell. This body of investigation is done in the presence of outdoor interference and the simulation results are backed up by a novel theoretical framework employing convex optimisation. Moreover, this optimisation problem has been demonstrated to be meaningful in the context of considering capacity saturation of realistic modulation and coding schemes. The results yield insight into the relationship between the outdoor and indoor aspects of the cellular network, as well as the propagation parameters.
