Developing a Mobile WiFi Tracking Unit |
Modern mobile and portable devices such as laptops and smart phones are often WiFi enabled. In the event that they are lost or stolen, it is desirable to recover them and their contents if possible. This research focuses on the development of a mobile system for locating WiFi enabled portable devices via the WiFi signal emanating from them. A mobile localisation system utilising a combination of a directional Yagi antenna and the received signal strength was developed and shown to be effective at locating WiFi sources at ranges from 45m to 500m away depending on the environment.
