Expositive/participative classes will be more participative than expositive. Theoretical classes will be recorded in advance and students will be required to watch videos before attending classes. In this way, pure theoretical classes will be substituted to participative classes where details will be stressed and doubts will be solved. This method will allow to employ more hours to exercise solving in the classroom.

"Fundamentals of Wireless Networks", starts with a review of the basic properties and parameters of antennas in transmission and reception such as radiation diagrams, directivity, gain, efficiency, impedance, polarization, radiation regions, antenna noise temperature, etc.
The types of antennas currently existing and their frequency ranges and associated applications will be descriptively displayed.
Subsequently, the necessary concepts will be formulated to design terrestrial radio links with the necessary concepts of propagation (reflection, refraction and diffraction in objects that intervene in the radio link), Fresnel zones, propagation in complex environments, radio spectrum, regulation and rules.
The course will continue with the basic operating principles of satellite communications systems. In particular, the physical principles that govern the orbits, their forms, periods, Kepler's laws, etc. Topologies and special characteristics of satellite communications systems, both terrestrial and space equipment are analysed.
Subsequently, the student will be introduced to the most current wireless communications systems; specifically in the technologies based on the IEEE 802.11 (Wi-Fi), 802.16 (WiMax) and similar (Bluetooth, ZigBee, UWB, RFID) standards that have achieved high levels of implementation and commercial penetration, exceeding the scope of applications and services for which they were initially conceived. The current status of wireless communications networks will be reviewed, and the necessary aspects (techniques, access protocols, etc.) will be analysed for the design and deployment of this type of networks, requirements (bit rate, coverage, consumption, QoS, etc.)
Finally, the subject will end with a chapter dedicated to mobile cellular communications in which the operation and the problems associated with mobile communication systems will be described in their most general conception. It is noteworthy that the universalization that these systems have reached in society during the last decades, and their constant technological evolution, requires that this chapter of the subject be very dynamic and permanently adapted to constant changes. Issues such as mobile communication propagation, channel characterization, fading, cell sizing and resource reuse, coverage / capacity relationships will be discussed and finished with a review of the old 2G systems (GSM / GPRS) and an introduction to the current 3G (UMTS / HSPA) and 4G (LTE) systems, 5G system and future 6G.
