Peha, “Impact of considering the ITU-R Two Slope Propagation Model in the System Capacity Trade-off for LTE-A HetNets with Small cells,” in Proc. of 32nd URSI GASS 2017, Montreal, Canada, Aug. 2017.http://hdl.handle.net/10400.6/7206This 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).engThroughputMathematical modelPropagation lossesAnalytical modelsComputational modelingRadio transmittersReceiversImpact of considering the ITU-R two slope propagation model in the system capacity trade-off for LTE-A HetNets with small cellsconference object10.23919/URSIGASS.2017.8105195
