97968 - LABORATORIO DI TELECOMUNICAZIONI P-BO

Academic Year 2022/2023

  • Teaching Mode: Traditional lectures
  • Campus: Bologna
  • Corso: First cycle degree programme (L) in Mechatronics (cod. 5818)

Learning outcomes

At the end of the laboratory, the student has basic knowledge of the main communication technologies, wired and radio, for the applications of Industry 4.0. In particular, the student is able to understand its performance and appropriately choose, given a set of application requirements, which technology is the most suitable for the specific case.

Course contents

The course will start with fundamentals on networks, protocols architectures and Internet. After that, the course will focus on the analysis of the different protocols of the protocols stack: link layer (channel coding and MAC protocols), network layer protocols (network topologies, routing protocols), up to the transport layer. The course will end with an overview of wired and wireless communication technologies for Industry 4.0.

Below is a list of the topics covered in more detail.

  • Introduction to Network fundamentals: protocols architecture, Internet
  • Link Layer: channel coding, multiple access protocols, performance in the presence of interference
  • Network Layer: topologies, network protocols, transport protocols (TCP, UDP)
  • Wireless solutions for Industry 4.0: IEEE 802.15.4 / Zigbee, LoRa, NB-IoT, 5G
  • Wired solutions: Ethernet, EtherCAT

The laboratory activity will allow the student to first observe the behavior of a communication link, characterize its performance, in terms of received packets and latency. Later on, the student will have the possibility to observe a small network and the related packets exchanged among devices, using Wireshark. In the laboratory students will use Freescale MC1322 devices, compatible with IEEE 802.15.4 / Zibgee standard, and SX1272 Semtech, LoRa devices.

Teaching methods

Chalk & talk - approx. 10 hours

Laboratory activities (groups of 3 students) - approx. 15 hours

Seminars - approx. 5 hours

Assessment methods

The exam is an oral exam consisting in two questions: i) one question concerning the theoretical part of the course (link layer, network layer, transport layer; ii) a 10 minutes presentation with slides in power point, on one of the laboratory activities selected by the student.

The final grade is defined as follows: starting the oral with 30 and decreasing the mark at each wrong answer.

Teaching tools

Theoretical part: books, slides, notes, in-depth material.

Laboratory: 802.15.4 / Zigbee devices, 868 MHz LoRa devices, sniffers, Wireshark.
