- Basic principles of propagation and antennas;
- Losses in free space and power budget.
4 - Analog-to-digital conversion:
- Sampling theorem;
- Pulse Code Modulation (PCM);
- Differential PCM modulation and Delta modulation.
5 - Principles of digital transmission and characterization of wired physical transmission media:
- Non-differential and differential transmission;
- Bit synchronization and error detection;
- Line coding;
- Characterization of copper and fiber optic cables and cabling analysis parameters in the context of structured cabling.
6 - Introduction to data networks:

- IPv4 addressing;
- Routing protocols: RIP.
8 - Ethernet Technologies
- Medium access control methods: CSMA/CD, CSMA/CA;
- ARP protocol;
- Switching protocols: IEEE 802.1d, 802.1p, 802.1q.
Evaluation Methodology
Written exam in one of the Assessment periods (60%) and laboratory work (40%). The evaluation method is the same for all evaluation periods. Approval in the course requires a minimum classification of 40% in the written exam and a minimum classification of 50% in laboratory work. The minimum grade to pass is 10 out of 20.
