Reflection coefficients and penetration losses for common building materials at 28 GHz show that outdoor building materials are excellent reflectors with the largest measured reflection coefficient of 0.896 for tinted glass as compared to indoor building materials that are less reflective.
Abstract
In this paper, we present reflection coefficients and penetration losses for common building materials at 28 GHz for the design and deployment of future millimeter wave mobile communication networks. Reflections from walls and buildings and penetration losses were measured for indoor and outdoor materials, such as tinted glass, clear glass, brick, concrete, and drywall at 28 GHz in New York City. A 400 Mega-chip-per-second sliding correlator channel sounder and 24.5 dBi steerable horn antennas were used to emulate future mobile devices with adaptive antennas that will likely be used in future millimeter wave cellular systems [1]. Measurements in and around buildings show that outdoor building materials are excellent reflectors with the largest measured reflection coefficient of 0.896 for tinted glass as compared to indoor building materials that are less reflective. We also found that penetration loss is dependent not only on the number of obstructions and distance between transmitter and receiver, but also on the surrounding environment. The greatest penetration loss containing three interior walls of an office building was found to be 45.1 dB, with 11.39 m separation between the transmitter and receiver.

Millimeter Wave Picocellular System Evaluation for Urban Deployments

TL;DR: It is found that millimeter wave systems can offer an order of magnitude increase in capacity over current state-of-the-art 4G cellular networks with similar cell density, however, it is also shown that such mmW networks will operate in an extremely power-limited regime where the full spatial and bandwidth degrees of freedom are not fully utilized.

28-GHz indoor channel measurements and analysis of propagation characteristics

TL;DR: The results show that indoor environments can enhance received signal power in LOS case, however, in NLOS condition penetration loss caused by wall and door may bring considerable attenuation, which implies that smaller cells will play an important role on increasing the probabilities of LOS links for the future communication systems.
