Basics on mathematics and physics

Obiettivi

The module presents the architectures, protocols and services of the current and future telecommunication networks. After introducing the requirements (bandwidth, real time, etc.) of voice, data and video and a brief description of the legacy PSTN (TDM) infrastructures ( originally designed only for phone services), the main features of an integrated multiservice IP-based backbone are described. Such IP based architecture is a essential element for the growing digital services and applications (i.e. web 2.0, cloud computing, big data, etc.) Among the various access networks the fixed access (i.e. ADSL, NGAN-fiber based, etc.) and mobile and wireless access are covered. Regarding the mobile technologies, the course presents the evolution from GSM/GPRS/EDGE to 3G systems (UMTS/HSPA) up to 4G-LTE architectures, services and applications. For the local environments wired (LAN) and wireless (WiFi) standards are described including the upcoming wifi-mobile integration. Finally Voice over IP and audio/video streaming architectures and protocols are described.
