Tools for Acoustic Indoor Lozalization Systems

Abstract

The performance of Ultrasonic Indoor Positioning Systems (UIPS) is determined by many factors; in fact, there is a wide variety of choices to be made on equipment, beacon deployment, signal configuration or positioning methods depending on the application. This tutorial analyzes these choices with the aid of a simulation software and an online demonstrator that offer analysis and testing flexibility for UIPS researchers and developers. The simulation software allows the testing of most common encoding and modulation techniques under a configurable UIPS, which also models the ultrasonic transducers’ response, beacon distribution, channel propagation effects, and allows the testing of different positioning algorithms. It is linked to an online demonstrator that can be managed remotely from a laptop/personal computer, avoiding any hardware requirement for researchers, thus enabling a fast and easy way of carrying out experimental tests in a laboratory environment, while avoiding the time-consuming tasks related to electronic design and prototyping setup in the UIPS field.
