Intended learning outcomes

The course aims at providing the students the fundamentals packet oriented wireless communication systems.  After successful completion of the course the student should able to perform performances analysis of media access protocols, in particular in packet radio systems with specific emphasis on radio layer aspects as fading, interference and power capture phenomena are treated.

Course disposition

The course is an ASP course in the GST curriculum. It is suitable as a first postgraduate (Ph.D) course for students in the telecommunication graduate school and as advanced course in the 4th year of the M.Sc program for students considering to join the PhD program.

Ethical approach

  • All members of a group are responsible for the group's work.
  • In any assessment, every student shall honestly disclose any help received and sources used.
  • In an oral assessment, every student shall be able to present and answer questions about the entire assignment and solution.
