Indoor Models of Heterogeneous Networks

Technology evolution over the last few years added many demands on mobile networks. To be able to support and handle the new technologies requirement and keep the customers satisfied, network operators need to increase the capacity, coverage, and performance of their networks. Low power nodes considered a promising method to satisfy future demands. This thesis work describes implementation of the 3GPP indoor pico models (TR36.814) for LTE heterogeneous networks and investigations by means of simulation for different scenarios to better understand the impacts of deployment position, interference, and load balance on system performance. The simulator is MATLAB based provided from Ericsson Research AP. It has found that, pico nodes coverage area is limited to indoor. In most of the cases, the transition zone area (i.e. where the optimal cell selections differ between downlink and uplink) is covered by the building wall. The users in the transition zone area indoors have acceptable performance, comparing with the ones outdoor, since degrade in their SINR level is less. In addition, low power nodes are able to handle larger load traffic share than macro nodes since they are more protected thus they have better channel conditions than macro nodes.
