Mobile communication is on the brink of another transformation as fifth generation networks and their architectures are already mature for deployment. As the volume and intensity of data flow drastically increases, the technologies that fuel such changes need to be evolved. Mobile small cells are going to play a key role in the deployment of these new communication infrastructures, extending the reach of wireless access. In this paper a number of path loss models for and indoors office environment are simulated using Mininet-WiFi. The channel characterization is based on a set of parameters including RSSI, SINR, latency, throughput, etc. The preliminary results indicate that ITU and multiwalls multi floors models are accurate enough to be used as a basis for an intelligent, cloud based radio resource management of heterogeneous wireless mobile small cells.
