Abstract(s)
This work aims at understanding and evaluating the impact of using different path loss models in the optimization trade-off of small cell (SC) networks. In LTE-A, the more realistic propagation models are the more efficient the radio and network optimization becomes. In this work we compare four urban path loss models: the urban/vehicular and pedestrian test environment from the ITU-R M. 1255 Report as well as the two slope Micro Urban Line-of-Sight (LoS) and Non-Line-of-Sight (NLoS) from the ITU-R 2135 Report. The two-slope model considers the existence of a breakpoint in the behaviour of the path loss and yields a significantly lower throughput per square km than a traditional one-slope model if and only if cell radius is small (coverage distances, R, up to breakpoint distance divided by the reuse pattern).
