The classes of this course will be in English (both speeches and slides).

Students will learn communication systems and network architectures based on wireless technologies, protocol issues and integration techniques between wireless and wired systems, solutions for efficient implementation of wireless services. Students will be able to identify the technologies useful for the development of services for fixed and mobile users, and they will be able to design and manage wireless technology systems and services by dealing with technical and physical implementation issues.

Summary: # Introduction to wireless systems. Physical layer: - Fundamentals of wireless mediums, propagation, coding and channel techniques - monitoring and measurement metrics and techniques - mobility at the physical layer. System deployment, analysis and solutions for propagation problems. Data Link Layer. - Multiple Access Techniques and logical channels - logical channels and wireless duplexing, TDMA, FDMA, CDMA, Wideband CDMA - broadcast and point to point access policies, mobility at the MAC layer, time and space domain problems and solutions, multi-hop communication and channel capacity, techniques for efficient and reliable wireless communication. Network Layer: - mobile networks - addressing and device mobility - dynamic Routing and IP-based solutions. Transport Layer: - the wireless impact, reliable communication and TCP-based solutions. #System issues.

Information about the Exams

The course requires the development of a individual seminar on a subtopic related to the course topics. A oral part will be planned to present the seminar (more or less 60 minutes). By the end of the classes, some subtopics will be proposed, with various degrees of extensions possible. Interested students could proposed personalized topics (in this case the project application must be preliminary defined and agreed with the teacher, by sending an email with subject "Seminar Proposal exam of SRW A.Y. 20xx/20xx+1" to the email address . Once defined a seminar topic (predefined or personalized) the candidate must find the information and prepare a 40 minutes presentation (with no more than 45 slides) and a summary (pdf, ps, html) with the contents of the oral illustration, material, references, etc. Once the presentation and summary has been prepared, the students must contact the teacher and s/he will be invited to the oral part possibly during the week following the request. The oral part will be kept in the teacher's office (T08) or in a room of the Department of Computer Science and Engineering, in Mura Anteo Zamboni 7 and will be published on the mailing lists to allow students participation. The oral part also includes questions on all the program of the course. The outcome of the seminar evaluation and oral part will provide two different evaluations in the range [0..30]. Both evaluations must be greater or equal to 18/30 to receive a sufficient evaluation and pass the exam. The final score is provided with different weights: seminar (75%) and oral (35%), total 110%. If the final total score is equal or exceeds 30/30 the student could be awarded with "cum laude" evaluation. It is facultative for students to propose the experimental setup and implementation of prototype applications and services based on wireless technologies (optional). The evaluation of the project will provide an additional basis to the total score up to 3/30 to be added to the evaluation of the seminar and oral part.

Remember to bring a valid document with photo during every exam event! This is needed for you to be identified. If not you will not be allowed to complete the exam on that scheduled event.

Course Material Wireless Systems and Networks A.Y. 2020/2021

This section will collect news and material used during the classes (including the slides). This is not the exhaustive collection of material to study. Some concepts will be provided with live lab experiences, videos, special software, etc. during the live lessons (whose attendance is of utmost importance).
