Description of achievement and assessment methods

In a written exam students proof their understanding of mobile broadband comunication and the related protocol by answering questions. With given use cases students proof their ability to apply methods for protocols and mechanisms by calculations. During the semester an optional mid term exam will be offered, which can be used to improve the final grade.

The final grade is composed of the following elements:- 100% final exam

The mid term exam results can be calculated with a bonus of 0.3 to the result of the final exam, if this leads to an improvement of the overall grade.

Exam type: written

Exam duration (min.): 90 Minutes

Possibility of retaking: In the next semester: Yes; at the end of the semester: No

Homework: No

Lecture: No

Conversation: No

Written paper: No

Recommended requirements

Basic knowledge of communication networks and their analysis: -packet and circuit switching -communication protocols -evaluation methods for communication network performance analysis


Medium Access Control and Resource Management for broadband wireless and wireline networks and its performance analysis:

- requirements of emerging 5G communication networks

- Medium Access Control (MAC)

- (wireless) contention

-based MAC: Aloha, slotted aloha, CSMA (WLAN, Ethernet)

- resource partitioning, polling

- cellular network resource management: from TDMA to OFDMA, scheduling, cellular principle, architecture, protocols (HSPA, LTE, LTE-A)

- packet switching, label switching (MPLS)

- Software Defined Networking (SDN) and OpenFlow

- Dependability

Study goals

After successful completion of the module students gained an understandig of the principles of resource management for fixed and mobile broadband communication networks with a focus on layer 2 protocols (medium access control) and their building blocks, and are able to apply methods for protocol design, resource management, traffic engineering and the analysis and evaluation of network protocols and architectures.

Teaching and learning methods

Learning method: In addition to the individual methods of the students consolidated knowledge is aspired by repeated lessons in exercises and tutorials.

Teaching method: During the lectures students are instructed in a teacher-centered style. The exercises are held in a student-centered way.

In addition, students are asked to read 1-4 scientific articles to be discussed during the lecture and tutorial hours.

Media formats

The following kinds of media are used:

  • Presentations
  • Lecture notes
  • Exercises and solutions for download
  • Videotutorials


Textbooks will no be explicitly used. Lecture notes will be provided. Books dealing with topics covered in BCN
