This paper considers what the minimum energy indoor access point deployment is in order to achieve a certain downlink Quality-of-Service. The paper investigates two conventional multiple-access technologies, namely: LTE-femtocells and 802.11n Wi-Fi. This is done in a dynamic multi-user and multi-cell interference network. The authors' baseline results are reinforced by novel theoretical expressions. Furthermore, the work underlines the importance of considering optimization when accounting for the capacity saturation of realistic modulation and coding schemes. The results in this paper show that optimizing the location of access points both within a building and within the individual rooms is critical to minimize the energy consumption.
