ults, with fading dips in excess of 30 dB, as well as overall increase in path loss in the case of loaded pallets, consistent with the fact that a higher percentage of links will be operating in partial line-of-sight or non-line-of-sight conditions in the latter case. There is an increase in the received maximum power level in the case of loaded pallets, which can be given by constructive interference in the line-of- sight components in the vicinity of the transceiver location for the specific scenario configuration. The analysis of the results obtained for the different scenarios presented shows that wireless channel connectivity is strongly influenced by the type of environment 8 Implementation of Context-Aware Environments with Massive IoT Systems (indoor/outdoor, dense urban, dense indoor), leading to variations in path loss values as well as in delay dispersion in time domain. In summary: The use of higher carrier frequencies from 868 MHz to 3.5 GHz leads to lower values of received power levels, owing to increase in path loss as well as to shadowing losses, given higher-frequency dispersive material losses, with average differences up to dB. The topomorphological characteristics as well as the network topology have a significant impact in terms of multipath components, with variations in terms of delay spread in the range of 1000 ns to over 6000 ns in the scenarios under test described. This can be extended also to variable link types given in different conditions in outdoor, indoor, and outdoor/indoor links, varying from line-of- sight, partial line-of-sight, to non-line-of-sight conditions. The requirements of IoT massive deployments in terms of node density, cost, and area of operation favor the use of sub 6 GHz frequency bands, which can be provided by combining LPWAN, WLAN, and 5G NR FR1 wireless communication systems. Future evolutions in B5G/6G will allow to further enhance operation, by adding additional access networks for IoT, such as VLC and different options of fronthaul links mainly for aggrega
