Abstract
En la actualidad la gran mayoría de dispositivos móviles disponen de diversos sistemas de localización, siendo el GPS el más habitual. Gracias a ello nuestro dispositivo conoce en cualquier momento la posición en la que nos encontramos, dando pie a un extenso abanico de posibilidades. Posiblemente la más popular sea la navegación, pero conocer nuestra localización tiene muchas otras aplicaciones. Por ejemplo, podemos crear una aplicación de chat en la que las personas con las que podemos chatear, son aquellas que se encuentran más cerca físicamente de nosotros. Este proyecto busca analizar y comprender los fundamentos de la geolocalización mediante redes Wi-Fi, conociendo sus ventajas y desventajas frente a otras alternativas como el propio GPS. Se desarrollará una aplicación para dispositivos móviles con Android instalado que sea capaz de determinar la posición geográfica de un usuario mediante la información de las redes Wi-Fi recibida por el dispositivo móvil. Por otra parte, el desarrollo de la aplicación específica para Android servirá de igual modo para conocer las características y los fundamentos básicos de programación para el nuevo sistema operativo de Google. ___________________________________________________________________________________
Nowadays most of mobile devices feature di fferent positioning capabilities, being GPS capability the most frequent, so our device knows where we are at any point in time. This feature gives cause to a great potential. Possibly the most common use is mapping and navigation, but knowing our location has a lot of different uses. For instance, we could create a chat application where the people we could chat with are those you are nearest. This projects aims to analyze and understand the basics of geopositioning through Wi-Fi networks, knowing its advantages and disadvantages over other alternatives like the actual GPS. An application will be developed for Android devices, which will be able to determine the geographic position of the user based on the information about the Wi-Fi networks received by the device. On the other hand, developing an application speci fically for Android devices will also make possible to get to know the characteristics and fundamentals of programming for the new operating system by Google.
