Course contents
Intended learning outcomes
The course is focused on principles and architectures for communication networks with an emphasize on the system level and the lower layers of the open system for data communications.
After completing the course the participants should be able to
- explain the common models for data communication between open systems;
- calculate essential parameters such as attenuation, channel capacity, bit and baud rate etc. for an ideal communication channel and a channel with noise;
- understand and solve problems regarding basic modulation and channel encoding;
- perform cyclic redundancy check (CRC) for error detection;
- solve problems related to flow control and retransmission according to "stop-and-wait", "go-back-N" and "selective reject" for data links;
- explain different access methods in local area networks (wired and wireless);
- explain the differences between networks based on datagrams, virtual circuits and circuit switched networks;
- dimension transmissions networks and circuit switched networks using basic traffic theory;
- explain the functions implemented in the Internet protocol (IP);
- briefly understand the transport layer functions.

Examination and completion
If the course is discontinued, students may request to be examined during the following two academic years.
Grading scale
Examination
- LAB1 - Laboratory Work, 3.0 credits, grading scale: P, F
- TEN1 - Examination, 4.5 credits, grading scale: A, B, C, D, E, FX, F
Based on recommendation from KTH’s coordinator for disabilities, the examiner will decide how to adapt an examination for students with documented disability.
The examiner may apply another examination format when re-examining individual students.
Other requirements for final grade
Passed written exam
(TEN1, 4.5p), grades A-F
Passed lab assignments
(LAB1 3p), grades pass or fail
Total grades A-F
Opportunity to complete the requirements via supplementary examination
Opportunity to raise an approved grade via renewed examination

Ethical approach
- All members of a group are responsible for the group's work.
- In any assessment, every student shall honestly disclose any help received and sources used.
- In an oral assessment, every student shall be able to present and answer questions about the entire assignment and solution.
