The course includes two modules of 5 credits each:
1) Mobile Radio Networks
2) Wireless Internet
The two courses will be offered in parallel during the semester for avoiding conflicts with the weekly schedule of the other courses. However, the lecture planning is organized so that the students attending both modules will have an integrated presentation of the two sets topics.
