A new mathematical model for wireless signal path loss under varying conditions

The Measurement of radio wave propagation into and within buildings at 900 and 1800 MHz frequencies have been undertaken using the library building at the University of Bridgeport campus in CT, USA. Furthermore, the signal propagation for the cases into and within elevator has also been investigated. Signal loss is a major problem for cellular wireless devices, resulting in dropped calls and failure in downloading data. In this research explores the radio transmission model of buildings that depend on the measured penetration loss values. Furthermore, this study will focus on and bring to light a better understanding of the modeling of radio transmission within and outside buildings. The lossy WiFi wave propagation around and within buildings is studied utilizing college buildings at the University of Bridgeport (UB) campus in Bridgeport CT. These buildings serve as good experimental settings because they exemplify typical signal dead spots, locations where little to no WiFi signal is available. In this paper, we investigate path loss propagation inside and outside buildings and we identify and categorize these problems. We then apply our path loss propagation algorithmic models to show that signal strength is significantly improved when compared to existing algorithms. Finally, we show the efficiency of our model and explain the specifics of our algorithm.
