“…Where, α is the path-loss exponent, β is a specific attenuation constant which accounts for excess attenuation due to the presence of walls or indoor clutter and d is the overall link distance. BEL can be extracted from measurement campaigns in different representative environments, see for example [3], [7]- [11]. Nevertheless, simple formula such as the one in [20] can be used to compute attenuation through a low-loss slab, if the effective material parameters (real and imaginary part of complex permittivity) of the wall are known at the considered frequencies.…”

“…Therefore, the spectrum below 6 GHz and at the low mm-wave bands at around 27 and 38 GHz still represents a good choice for nearfuture communication systems [5], [6]. Various measurement campaigns related to O2I propagation have been documented in the existing literature [3], [7]- [11]. Nonetheless, O2I propagation at mm-wave frequencies is still scarcely investigated in old southern-European buildings, that are characterized by thick walls and brick construction.…”

The limited power-budget is known to be one of the main constraints in mm-wave radio links, especially when in-building applications are considered. In particular, outdoor-to-indoor and through-floor attenuation need to be analysed and carefully characterized at mm-waves in order to correctly approach both coverage and interference assessment issues. Surprisingly, only a few studies addressed the problem and no recommendation has been provided by standardization bodies so far for mm-wave through-floor attenuation in different building types. Therefore, a measurement campaign at 27 and 38 GHz was carried out to investigate the aforementioned issues. It is observed that in-building losses heavily depend on the building type, and that modern construction techniques make through-floor penetration almost impossible. This fact highlights the need for standard models for mm-wave through-floor propagation in different kinds of buildings.
