Learning outcomes
Give students the knowledge to understand problems and technical solutions to operate a communication system. Impact of the environment and of the service type on the preferable solution. Description of the main commercial systems with reference to the studied techniques. It is assumed that students don’t have any background in telecommunications, and will be more interested in their exploitation in industrial environments. As a consequence, the theoretical aspects will be limited and focus will be on application examples.
Course contents
Characterization of signals:
- Characterization in time
- Characterization in frequency
- Statistical properties
Characterization of transmission impairments. Propagation phenomena and how to design efficient transmission techniques. Transmission over radio channels. Attenuation, multipath, fading, doppler effect, crosstalk.

Review of transmission techniques (analog and digital) analog to digital conversion, transmission of baseband digital data: robustness to noise and bandidth efficiency.

Introduction to traffic theory for performance characterization and system planning. Kendall's notation, Little's result, transition matrix and state probabilities for Markov systems, birth death processes, examples.

Circuit switched networks: space, time and hybrid circuit switched nodes. Minimization of crosspoints. Blocking probability. Signaling, in-band, out-of band, common channel. Multiplexing in circuit switched networks frequency (FDM), time (TDM) and code (CDM). Duplexing.

Packet switched networks. The ISO/OSI reference model, protocols and interfaces. Line management, link configuration, packet extraction, error control (FEC and ARQ). Sample protocols: HDLC, PPP.
Distributed multiplexing in packet networks: Aloha, Slotted-Aloha, CSMA/*, Token passing.

Local packet based systems. Wired and Wireless Local Arean Networks (LAN) in the IEEE 802 set of standards.
Short range and sensor networks.
Networks and applications in industrial environments

Wide area packet networks. Historical perspective, Frame relay and ATM networks. Quality of service concepts. Internet architecture and protocols (IP, TCP, UDP). Evolution and convergence to IP based networks.
