Teaching Methodologies
In lectures, the teacher exposes the elementary concepts associated with the existents wireless communication
systems (expository). In practical laboratory classes is privileged direct contact with real scenarios and existing
technologies. Students have to perform in groups, three practical assignments and a project of medium complexity.
Evaluation: The final grade is obtained from the following components: Written exam (WEx) to be held at the end of
the semester and Practical Work that includes a microproject (PW). The Final Grade (FG) is the weighted average of
these components according to the equation FG = 0.7 x 0 WEx + 0.3 x PW.
The approval in this curricular unit requires the achievement of at least 9.5 values in the FG (on a scale of 0 to 20
points), being necessary to obtain a minimum mark, equal to 8.5 (on a scale of 0-20) on the written final
examination.
