Path loss characteristics between different floors from 0.8 to 37 GHz in indoor office environments

This paper describes analytical results obtained for floor penetration loss characteristics and their frequency dependency by measuring in multiple frequency bands, including those above 6 GHz, in an indoor office environment. Measurement and analysis results show that the floor penetration loss depends on two dominant components: paths through floors and outside buildings. It was clarified that the characteristics of these paths determine the frequency dependency of the floor penetration loss.
