The authors propose a new network model framework, denoted heterogeneous fluid model network, which allows to derive closed formula for the Signal to Interference plus Noise Ratio (SINR) received by a mobile in heterogeneous cellular networks, composed of macro cells and femto cells. Quality of Service (QoS) and performance of wireless networks can therefore be analyzed in a simple way. They apply their model to Long Term Evolution (LTE) and indoor/outdoor environment. This model allows to analyze the deployment of a femto cells network when the femto base stations share the same bandwidth as deployed macro cells.
