The lecture is offered for Master Computer Science (module MA-INF 3202) Lecture and Exercises/Tutorials will be given in English language.

Course:

Exercises:

Other:

  • Term: Master Computer Science
  • Requirements: Basic knowledge of communications systems and protocols, e.g. from a Bachelor course on computer networks (or similar topics)
  • Faculty: MA-INF 3202
  • Effort: 2L+2E / 6CP
  • Follow-up/Side-events: We are offering a periodical seminar and a lab in each semester. However, the research activities of our department ar currently focused on IT security, thus it is not foreseeable how many topics related to Mobile Communication will be on offer.

Announcements

Exam dates (in person):

  • 1st exam: 2022-07-26, 10:00 - 12:00, Friedrich-Hirzebruch Allee 5 - Hörsaal 2

For hybrid lectures: Here is the undefinedBBB room

  • 2022-06-24: The practical exercise sheet is completed now, we would be grateful if you returned the LoRa ESP32 boards to use, the best opportunity for that is right after the lecture.
  • 2022-05-24: Exercise sheet 08 includes a practical task for which you need a small device called a LoRa32 microcontroller. We hand some out in the lecture today as well as next week, but you can also come by our office to grab one. All details will be explained on the exercise sheet which is expected to be released tomorrow.
  • 2022-04-19: We noticed that there are multiple students which registered a PECAS group but do not appear in our list of participants that was derived from the registrations in TVS. We do not have any means to contact such students directly because we only know the GitLab account name and don't have any names, matriculation numbers or email addresses. If this description fits you, YOU NEED TO BECOME ACTIVE. Please send an e-mail to the orga mailing list, containing the names, matriculation numbers, CS account names and e-mail addresses of all participants of your PECAS group. GitLab-participants that do not appear in our list of participants will be removed from repositories, futhermore the PECAS registration system will be closed, by the end of this week.
  • 2022-04-05:
    • The MoCo lecture officially started with the hybrid lecture on April 5th, 2021.
    • For the MoCo course we plan to live stream the lecture and exercise sheets will be handed out online and have to be submitted online as well. The tutorials, which are not mandatory to attend, however, will be in presence only; as well as the exam(s) at the end of the course.
    • During this meeting, we discussed all important information about the lecture, exercises, etc. The presented organizational slides and the recording can be found below on this website. Make sure to register in TVS

Prerequisites (recommended)

We recommend existing basic knowledge on computer networks and communication systems protocols, e.g. coming from appropriate courses of your Bachelor programme. For the Uni Bonn German programme "Bachelor Informatik" we recommend participation in the course BA-INF 101 "Kommunikation in Verteilten Systemem (KIVS)". All lecture material (slides, assignment sheets, ...) is available in English language and maybe helpful also for Master students who have not done the BA degree in Bonn. You can access the recent course material (of winter term 2021/22) here on the KIVS web page (no username/password required from within the University computer network).

Contents

Mobility Management in the Internet, Wireless Communication Basics, Wireless Networking Technologies, Cellular/Mobile Communication Networks (voice and data communication), Ad-hoc and Sensor Networks.

Mailing List - "Mobile Communication"

The mailing list "vl-moco" is used for news and organizational information concerning the lecture "Mobile Communication". An additional purpose is to discuss problems, e.g. with viewing or printing slides or assignment sheets. More information on subscribing the mailing list can be found undefinedhere. The mails on the list are being archived.

Slides and Presentations

The access credentials can either be obtained from undefinedthis eCampus course of the first slide set. No credentials are necessary if you are within the university network, either physically ot via the undefineduniversity VPN (Uni-ID required) or the undefinedcomputer science VPN (computer science account required).

The list of chapters and subsections is preliminary and maybe subject to slight changes.
