Bandwidth, network performance, QoS and network power consumption are important dilemmas of contemporary telecommunication networks. With ever increasing demand for data services, networks are destined to become denser and more power hungry, essentially increasing the capital and operational expenditure for operators around the world. One of the technological remedies to this situation is heterogeneous networks. In this work, we present a promising attribute of heterogeneous networks by offloading high QoS indoor users through femto. Additionally, we take traffic demand and sparse network deployment into consideration. The traffic demand is expressed in terms of area spectral efficiency and the power consumed in network nodes is expressed in terms of area power consumption [1]. The results suggest that with an increase in femto density the area spectral efficiency of the considered LTE network increases and decreases monotonously for sparse networks. From an operator's point of view, 100% offloading of premium users through femto is energy efficient at all area spectral efficiency targets. From an environmental perspective, 100% offloading of premium users is beneficial at low area spectral efficiency targets, while at high area spectral efficiency targets 40% offloading is energy efficient.
