he unsupervised and chaotic deployment of Home
eNBs (HeNBs) is leading to high levels of interference. To understand the behaviour of the interference of these uncoordinated deployments is vital to reach significant capacity improvement and also to explore some opportunity for any energy reduction.
This paper considers scenarios with high interference and middle interference levels, with a maximum of four users per cell. HeNBs are deployed indoor in order to cover a building. We theoretically analyse the traffic performance of this scenario through the study of the Signal to Interference plus Noise Ratio (SINR).
Through the use of the LTE-Sim simulator one obtains the quality indicators for two flows that are being utilised by the users. Video and one best effort are studied, while varying the transmitter power and the areas of the apartments.
The achieved SINR is higher when the area of the cells is smaller. The variation of the transmitter power of the HeNBs does not present any significant impact. Noticeable throughout the simulations is observed that is possible to operate the system without setting the transmitter power of HeNBs to the maximum value at both interference levels. Simulation results also show that with the considered flows is possible to serve the maximum number of four users per HeNB with high quality. Take in account the obtained results it is possible to promote a reduction in energy consumption of the HeNBs without penalizing the service quality.
