A model for signal attenuation due to path-loss combined with fading, shadowing and O2I loss. The O2I loss is the Outdoor-to-Indoor penetration loss where the signal attenuates when it penetrates through structures like concrete walls, glass, wood etc. Low-loss model is applicable to Rural Macro. High-loss model is applicable to Urban Macro and Urban Micro. None disables the O2I loss.
The O2I Models such as Low Loss and High Loss are associated with the type of material used in the buildings and are used to calculate the penetration loss in case of an indoor scenario. In case of scenarios where UEs are not inside a building these parameters will not have any impact on the results. In an indoor scenario, users will be able to notice differences in the SNR.
Building can be configured by clicking on Options > Configure buildings and Add a building in the grid.
- A building occupies a minimum 1 cell on the grid and a maximum size equal to the complete grid
- Two buildings cannot overlap one another.The maximum number of buildings supported in NetSim is Five
Buildings will have an impact on RF propagation losses if O2I Building Penetration Model is set to either LOW LOSS MODEL or HIGH LOSS MODEL as shown in the screenshot below:
