## 2 Methodology and Data Collection
### Kriging-Based Channel Model Development
The results and the methodology proposed in this study will help students in wireless telecommunications, professionals in the industry, and engineers to achieve efficient radio coverage estimation; estimate measurements in situations where the possibility to collect large amounts of data from measurement campaigns is very limited, reducing time and costs in practical campaigns; and to encourage them to perform Kriging-aided channel design, considering its accuracy to predict path loss in O2I NLOS links.
