La assignatura cobreix diferents aspectes relacionats amb l'Internet Mòbil, com ara les possibilitats i limitacions de tecnologies associades a la transmissió sense fills, xarxes cel.lulars, xarxes WiFi, i tecnologies de comunicació baix consum. També el processament del senyal de sensors incorporats als telèfons mòvils (aceleròmetre, magnetòmetre i giroscop) i tecnologies de posicionament. A les sessions de cas d'us es tracten aspectes que no son purament tecnològics, però que son importants per entendre la evolució i possibilitats del'Internet mòbil, com ara la cadena de valor, ecosistema, markets d'aplicacions, models de negoci, etc. Més concretament, els temes tractats sòn els següents: La cadena de valor del Internet Mòbil. Transmissió ràdio. Xarxes cel.lulars. Xarxes WiFi i tecnologies de curt abast. Protocols de suport a la mobilitat. Sensors. Tècniques bàsiques de processament del senyal dels sensors (filtres, fusió de sensors). Tecnologies de posicionament. Aplicacions mòbils (plataformes, models de negoci, limitacions, etc).

Use case: Mobile Application Design

The goal is to design a mobile application. You can choose an application. It will analyze the applications available on Apple App Store or Android Market with similar characteristics, comparing our implementation with the competition. We will choose a business model (ie, how will money with this application), marketing, etc.. We will design the application (graphics, functionality, etc.). On a voluntary basis can we deploy the application for Android OS and IOS. In this case you can publish the application for the market.
  • Laboratory: classes based on case
