1000 ns to over 6000 ns as a function of transceiver location. 8.2.3 Indoor Warehouse Scenario A final test case has been considered, corresponding to a large indoor warehouse location. This specific type of scenario is of particular interest in the case of IoT applications, as wireless nodes can provide multiple functionalities in relation to location and tracking of assets, as well as for building automation and control purposes among others. The schematic representation of the scenario under analysis, which corresponds to a real logistic warehouse location in the vicinity of the city of Pamplona, is depicted in Fig. 8.12. In this case, the wireless channel characteristics will be strongly dependent on the density and type of objects within the scenario, as in principle, a higher percentage of communication links will be operating in partial line-of-sight or non-line-of- sight conditions. Therefore, in order to consider the impact of this condition, the scenario has been implemented with a variable load setting in the pallets that are located in the vertical rack structures. To illustrate the impact of loading assets within the scenario (and hence, modifying the line-of-sight/partial line-of-sight/non- line-of-sight conditions), two different results have been obtained: for an empty warehouse (i.e., no loading on the pallets) and for a fully loaded warehouse (i.e., all of the pallets have been introduced inside the simulation scenario). The results for received power level distributions, for different frequencies of operation under consideration and the two loading level conditions, are shown in Figs. 8.13 and 8.14. The presence of assets within the scenario leads to higher path loss and, hence, to lower received power levels, which is given by a strong decrease in line-of-sight and partial line-of-sight propagating conditions in the case of loaded pallets. The results shown in Fig. 8.14 have been obtained for different transmitter locations, which also indicate the strong dependence of the wireless channel cha
