Nomadic Communications - aa 2012-13
Past academic year courses: bottom page
The course is held, as usual, jointly by Dr. Alessandro Villani and myself.
I will cover mostly the theoric/descriptive parts, while Alessandro will take care of the labs. The program is described on the official Faculty page. Labs are mandatory, part of the exam will be based on Lab reports. This year the labs will be more focused on HotSpot management and design and less on measures and experiments.
- We begin the course with a rush on theory, in order to have enough knowledge of Wireless Networks, WIFI and 802.11 standard and systems before we start the Labs. This means that the first three weeks we have only theory:
- Monday Feb. 18, 8:30-10:30 room A108
- Monday Feb. 18, 14:30-16:30 room 101 (IRST)
- Wednesday Feb. 20, 14:30-16:30 room A108 NEW !!
- Monday Feb. 25, NO LESSONS FOR ELECTIONS
- Monday Feb. 25, NO LESSONS FOR ELECTIONS
- Wednesday Feb. 27, 14:00-15:00 room A208
- Monday Mar. 4, 8:30-10:30 room A108
- Monday Mar. 4, 14:30-16:30 room A208
- Wednesday Mar. 6, 14:30-16:30 room A208
March 11 we start the regular calendar
- Theory: Mondays 8:30-10:30 room A108
- Mondays 14:30-18:30, A207. On Mondays Alessandro will explain the laboratory topic, help you setup experiments and answer all questions.
- Wednesdays 14:30-18:30, A204 is reserved for you to complete experiments, but we probably do not need it.
The formal exams dates during the summer are:
- June 3, 2013
- July 22, 2013
- Sept. 2, 2013
You have to subscribe via ESSE3 when you want to take the exam, however the actual date of the exam is free, you just have to take an appointment with me. I strongly encourage groups to take the oral together, but there is no fromal requirement on this. This summer I'm mostly not in Trento for work, thus you should take the oral exam before June 8, between June 24 and June 29, between July 29 and August 1 or in September.
The oral can be taken when the lab reports are delivered in their final form, but you have to allow me 3-4 days minimum to correct the reports. I can receive and correct reports via e-mail also when I'm not in Trento in July, but in June.
This year the labs are centered on HotSpot planning and management, you will see how to use different softwares (both free and proprietary) for AP management based on the CapWap architecture (more on this will be taught in theoric lessons), and you will have to discover APs and their use in our buildings as well as to plan possible improvements for our system. Labs are best done in pairs, specially for writing the reports. Groups of three are accepted, as well as singles. More than three the work bocomes too dispersive.
- Feb. 20: Today lesson is moved to A108, also the other lessons in 101 (III IRST) will be moved, but still don't know where.
- Feb. 22: Remember NO LESSONS on Monday and wednesday 27 we have to anticipate to 1/2 hour to 2PM as I have to leave at 4PM sharp.
- Mar. 6: next week, we have theory monday (11) both morning (in Room 108) and afternoon (in Room A207), while labs start wednesday with an introduction on packet sniffing etc. of about 3-4 hours (Room A204). Please bring your laptops!
- Mar. 11: On Mon. 18 there is not theory lesson, next one will be Mon. 25.
- Apr 13: On Mon. 15 there is not theory lesson, next one will be Mon. 22.
- Apr. 22: The Lab activities are suspended today. The will restart regularly on Mon. 29. The drafts of the first report can be delivered up to May 3.
Teaching and Support Material
We don't have any "official textbook." Here are the printouts of the slides I use to follow a predefined course while teaching. They are by no means a textbook and I will spend maybe half a lesson on a single slide and ... surf over the next 10 in 10 minutes. They are intended to help you in scribbling notes, not to substitute the lessons. They are posted before the lesson, sometimes the evening before, but normally with a couple of days advance. If you want to have an idea of the whole material you can check the material of the past years, but I normally change part of the course, so do not entirely rely on old material.
- Introduction, general notions and rehearsal of known concepts
- Fundamentals of 802.11 and MAC Protocol
- Elements of communications systems (Fourier Transforms, Singlas, Modulations, Channel, ...); 802.11b/a/g/h PHY Layers and their interaction/influence on the MAC
Books on Communication Systems:
- Digital Communications by John G. Proakis
- Digital and Analog Communication Systems by Leon W. Couch
Propagation principles. Although it covers much more than we did in class, the following is a very good introductory tutorial to propagation principles and their effects on communication
- 802.11e: traffic differentiation and QoS in modern WiFi; Improving efficiency for novel PHY layers
- AP Management: CAPWAP and 802.11f
- 802.11n, bringing the thecnology to the limit
