It can be defined as the difference between received power in free space and that obtained with an obstructing material between TX and RX, according to Fig. Penetration loss is the signal attenuation caused by its propagation through a material. Section III presents the experimental results of the path loss and propagation coefficient in indoor environments with LOS and NLOS, whereas conclusions and proposals for future works are described in Section IV. Section II describes the methods used in the experimental setup to obtain the reflection coefficient and penetration losses of typical building materials. The paper is structured in four sections.

LOS (Line-of-Sight) and NLOS (Non-Line-of-Sight) environments have been considered in order to evaluate real scenarios of the future 5G networks. Next, it reports a detailed analysis on path loss and propagation coefficients based on experimental measurements and computational simulations performed with Altair WinProp™, using the previously determined reflection and transmission coefficients. This paper first presents material characterization based on measurements of the reflection coefficient and transmission loss of common Brazilian building materials at 28 and 38GHz. Sun, “Wideband Millimeter-Wave Propagation Measurements and Channel Models for Future Wireless Communication System Design,” IEEE Transactions on Communications, v. However, this can be mitigated by using high-gain adaptive antennas and transmission cells (clusters) with dimensions in the order of 200 m or even less, such as picocells and femtocells T. In fact, only the attenuation due to the communication channel in mm-waves will be higher, when compared to the attenuation in at microwave frequencies, which are used today for wireless access. The millimeter-wave frequency bands around 28 and 38GHz have been considered potential for 5G, since they but is significantly increase attenuation due to atmospheric gases absorption Attenuation by atmospheric gases, ITU-R Standard P.676-11,2016.] and rainfall Specific Attenuation model for rain for use in prediction methods, ITU-R Standard P.838-3, 2005.], as shown in Figs.
#RAY TRACING USING WINPROP FULL#
The developing fifth generation of mobile communications networks (5G) intends to use the millimeter-wave frequency bands to obtain the bandwidth required to meet the full demand of carrier subscribers and ensure the deployment success of Gbps per user. The millimeter-wave frequency bands (mm-waves) promise to meet this demand. Those forecasts have motivated the search for new frequency bands with enough bandwidth to meet the growing demand for mobile communications, since the traditional UHF and SHF bands are both already congested with the existing services.

The International Telecommunication Union (ITU), in one of its reports ITU-R, “M.2370-0 IMT traffic estimates for the years 2020 to 2030,” 2015.], forecasts in the period from 2020 to 2030 global data traffic will grow from 10 to 100 times. By 2021, it is estimated to reach 48,951 exabytes per month Cisco Systems Inc., “Cisco Visual Networking Index: Global Mobile Data Traffic Forecast Update, 2016-2021,” White Paper, Feb. The global mobile data traffic is estimated to increase 7-fold between 20, with annual growth rate of 47% Cisco Systems Inc., “Cisco Visual Networking Index: Global Mobile Data Traffic Forecast Update, 2016-2021,” White Paper, Feb. In recent years, the access networks of telecommunication operators have needed increasing data transfer rates and bandwidth to support all the data traffic generated by their subscribers.
