Abstract
Geographical location solutions have a wide diversity of applications, ranging from emergency services to access to tourist and entertainment services. GPS (Global Positioning System) is the most widely used system for outdoor areas. Since it requires a direct line of sight with the satellites, it cannot be used indoors. For indoor positioning, the most commonly used technology to calculate the position of mobile devices is Wi-Fi. In this article, we present a positioning tool called WiFiPos based on Wi-Fi signal processing. This tool uses different variations of the Fingerprint technique to analyze the performance and accuracy of the system both indoors and outdoors.
Keywords
Indoor positioning, Outdoor positioning, RSSI, Fingerprint, GPS.
