Telecommunications - what does it all mean? We will look at history and the future. We will try it wired and wireless, and even at the speed of light (or almost…), on earth, underwater, and in space. For example: • How is electricity generated? Morse, the painter. Alexander "ring the" Bell! Telecommunications from above. • Do you know a Twisted Pair? How a landline works. • How the telephone network becomes the Internet…. • Light and dark. Transmission of information by light. • Why are networks "mobile"? 1G, 2G, 3G, 4G, 5G, etc. The more G, the better it is? How about us and how else? • Satellite systems (J. Kepler + A. C. Clarke = E. Musk). What do Saturn and Earth have in common? Does navigation know about me (we will walk around Čakovice - the place, where Chuck Norris got lost)? • How television (and Internet TV) works: a football match and a drastic clash of the Titans. • Is WiFi not working? What now… • Why the Internet is not for people, but things. • The biggest mistakes in the history of telco-business. The subject anxiously avoids formulas and mathematical relations (but it does not always succeed…) - the spotlight is pointed on principles and clarity.

The course is completed with an exam. To pass the exam successfully, it is necessary to achieve at least 50% of the points in accordance with ECTS.

Points for the exam are awarded based on:

A) completing assignments during the semester (max. 50 points = 50%),

B) passing the final test (max. 50 points = 50%).

*Completing assignments during the semester:**
Active participation in ongoing testing (usually simple closed questions/statements of true/false type):

participation 90–100%: 50 points
participation 80–89%: 40 points
participation 70–79%: 30 points
participation 60–69%: 20 points
participation 50–59%: 10 points
participation <50%: 0 points

*Final test:**
The final test takes place in-person or (depending on attendance at lectures) on-line in the MOODLE. It consists of 25 questions randomly selected by the system from its database. Passing the final test is mandatory for all students.

success rate 90–100%: 50 points
success rate 80–89%: 40 points
success rate 70–79%: 30 points
success rate 60–69%: 20 points
success rate 50–59%: 10 points
success rate <50%: 0 points

The final point score is the sum of points from completing assignments during the semester and points earned from the final test. The student classification is as follows:

A: 100–90 points
B: 89–80 points
C: 79–70 points
D: 69–60 points
E: 59–50 points
F: < 50 points

Points for the exam can also be earned based on the best result in completing assignments (5 points).
