La Storia
Le Origini
1964
Nasce a Torino CSELT, Centro Studi e
Laboratori Telecomunicazioni, che sviluppa
ricerca per il Gruppo
2001
Nasce TILAB, dalla fusione di CSELT e della
BU Venture Capital & Innovation, con
l’obiettivo di aumentare l’Innovazione del
Gruppo Telecom Italia in forte coerenza
con le Business Unit del Gruppo
3
La Storia
Alcune Conquiste
1972
Realizzata la prima centrale italiana di
commutazione elettronica
1982
Posato il primo cavo in fibra ottica per la
sperimentazione del segnale TV
1988
Realizzati gli standard MPEG e MP3 per la
compressione del segnale audio video
1999
Effettuata la prima telefonata UMTS al mondo in
ambiente urbano
2009
A Torino parte la prima sperimentazione in
campo della tecnologia LTE

La Mission
Il Ruolo
Centro di Eccellenza
con la responsabilità di
garantire l’innovazione
tecnologica del Gruppo,
assicurando lo scouting di
nuove tecnologie e le attività
di testing, prototipazione ed
engineering dei servizi e
delle piattaforme di rete

Quanto costa un cellulare?
Fabio Ricciato

Margini della

+ Distribuzione -

+
Licenze
ed IPR
+ Williness = Prezzo al
to pay
consumo
Cost drivers
Innovazione tecnologica: le tecnologie più innovative sono appetite dai Tech Fans ed incidono
significativamente sul costo/prezzo. Ciò è dovuto ai costi di ricerca e sviluppo e al ricarico dovuto
all’indice di rischio per la tecnologia stessa.
Chipset: funzionalità maggiori richiedono chipset più potenti (l’ultimo modello), più memoria volatile e
storage, un maggior numero di periferiche corrisponde ad un maggior numero di chip e funzionalità
di comunicazioni avanzate corrispondono ad un costo del chipset di comunicazione maggiore.
Display e camera: display e camera ad alta risoluzione e con più profondità di colore.
Shell: forme, meccaniche e materiali più raffinati aumentano i costi di base e di manifattura.
Batteria: applicazioni complesse implicano un maggiore utilizzo dei processori e quindi una maggiore
power consumption; un elevato utilizzo corrisponde ad un uso del display più prolungato.
Licenze software: funzionalità maggiori come sistemi operativi full-featured, codec multimediali
avanzati, software applicativi di terza parti (ad esempio browser, Java virtual machine) incrementano
il costo del software e delle licenze.

SIM Card
Fabio Ricciato
What is a SIM ?
"A SIM is the physically secured module which contains the IMSI, an authentication
algorithm, the authentication key and other (security related) information and functions.
The basic function of the SIM is to authenticate the subscriber identity in order to prevent
misuse of the MS (Mobile Station) and the network.“
(tratto dal report del meeting SIMEG#1 Gennaio 1988)
22
La SIM è nata per rispondere a esigenze di
Sicurezza & Identificazione
La SIM contiene gli algoritmi di autenticazione e cifratura dell’operatore mobile ed
identifica univocamente l’abbonato
Portabilità
La SIM risponde a standard internazionali che ne permettono la portabilità da un terminale
all’altro garantendo piena interoperabilità, oltre alla personalizzazione dei terminali coi
dati personali dell’utente (rubrica, preferenze,…) e dell’operatore (plmn per facilitare il
roaming,..)
23
La SIM è una ‘Smart Card’
Ovvero è una carta dotata di microchip in grado di memorizzare e processare
dati
24
JavaCard
Una JavaCard è una smart card con una
Java Card Virtual Machine a bordo in
grado di far girare applicazioni
scritte utilizzando un sottoinsieme di
Java (applet)
Un applet JavaCard può essere installato
su carte prodotte da manifatturiere
differenti ed utilizza una libreria
(JavaCard API) standard
JavaCard è stato standardizzato da SUN
e da JavaCard Forum

Widgets
Widget is a standalone Web application
Typically front-end a Web 2.0 service or other Internet content
Local on the handset & distributed like any other application
Widget at its core is a Web page designed for a specific purpose
Widgets use same technologies, HTML, CSS, JavaScript, AJAX,
as Web pages redered through a browser windows
Types of Widget
Mobile Widgets
Accessory widgets (clock, calendar …)
Application widgets (games, address book …)
Information widgets (weather, stocks, rss, …)

Mobile M2M: Development environment
AT commands
Cellular M2M modules and modems are just another type of modem
Use standard AT commands
Manufacturers have created unique sub-sets of vendor specific commands to access various functions
Developers run their applications in almost all popular programming languages including
.NET
Windows CE
Linux
ANSI C
Python
Java
Manufacturers have developed software coding tools to simplify application development for devices with
on-board embedded memory
Examples include M2mpower, MUSE, EasyPython
