Informazioni generali
Descrizione e obiettivi formativi
Il Corso, interamente svolto in lingua inglese, ha l'obiettivo di offrire una formazione di livello elevato nel settore dell'ingegneria dell'informazione, ovvero nelle discipline collettivamente riconosciute come appartenenti all'area ICT (Information and Communication Technologies). E' maggiormente specializzato nelle discipline dell'Ingegneria di Internet e delle infrastrutture di comunicazione. Tuttavia, soprattutto nei percorsi a scelta guidata suggeriti allo studente, il corso non si limita a coprire tale settore, ma ambisce a fornire competenze trasversali nell'intero settore ICT, e a preparare anche nuovissime ed emergenti figure professionali, quali i cosiddetti "data scientists", fornendo strumenti e metodologie per analizzare ed estrarre informazioni dalle enormi moli di dati che caratterizzano la società digitale moderna.
Il corso permette una formazione in Sistemi e infrastrutture o in Gestione e servizi, con una ampia base di formazione comune.
Sbocchi professionali
Tra i principali sbocchi professionali: imprese di progettazione, produzione e installazione di apparati, sistemi e infrastrutture riguardanti l'acquisizione e il trasporto delle informazioni e la loro utilizzazione in applicazioni telematiche; le imprese di pianificazione e di esercizio di reti di telecomunicazione per l'offerta al pubblico sia dei servizi interattivi, fissi e mobili, che di quelli diffusivi; imprese pubbliche e private di servizi di telerilevamento e radiolocalizzazione; enti pubblici normativi e di controllo delle telecomunicazioni; enti di controllo del traffico aereo, terrestre e navale.
Possono essere svolte funzioni di
• consulente (configurazione, progettazione di reti e servizi in area locale, certificatore, troubleshooting, "data scientist")
• Imprenditore (servizi innovativi Internet, Web, Mobile; tecnologie e piattaforme di acquisizione, trasporto, distribuzione ed analisi dei dati e segnali).
• Impiegato in enti di ricerca ed alta formazione;
