Indoor/Outdoor Propagation Modeling on Georgia Tech Campus

Introduction

With the increasing popularity of wireless communication, it becomes necessary to accurately model the signals of cell phone calls that originate indoors. Past propagation models were created solely with outdoor, or in-vehicle, calls in mind. As a result, there is an overwhelming need for newer propagation models that will incorporate indoor signal strengths. Provided with details of 8 antennas, located on the Georgia Tech campus, 4 of which included received power maps, the received power maps of 4 antennas were to be predicted. By predicting these values, the 8 antenna sites on the Georgia Tech campus can be properly modeled, thus describing the indoor and outdoor propagation characteristics.

The procedures used in determining the unknown received power values can also be applied to other locations, not just the Georgia Tech campus. This can be viewed as nothing but a benefit for society. Assuming a proper and accurate model was created, wireless providers can use these models to locate their cellular customers in necessary situations. This allows the safety standards of our current society to advance, as anyone with a cell phone, in an emergency, can place a call that is capable of being traced.
