Information and networks

This unit provides an introduction to underlying technologies, major components and system-wide architectures of modern telecommunication systems. After introducing concepts of block and stream delivery, requirements of a telecommunications network and representation of analogue signals (e.g. voice and video) in digital form, the unit will cover all the major functions in layered architectures. Topics to be covered include multiplexing, basic line transmission and modulation, error protection and correction, packet switching, LAN protocols and the TCP/IP protocols on which the Internet is built. Particular emphasis is given to the major functions that combine to allow communication across key modern digital telecommunication systems such as the Internet, mobile telephony, digital TV and Digital Audio Broadcasting.

Problem-based learning - Weekly sets of practice problems and an investigatory mini-project.

Enquiry-based learning - Active participation in laboratories.

Peer assisted learning - Active participation in laboratories, practical sessions and discussion forum.

Active learning - Participation in workshops.

A typical week will involve:

• Viewing a number of short videos explaining the theory, with embedded checks on understanding.

• Participating in a weekly workshop, gaining a wider perspective of the theory and applying it to sample problems.

• Completing provided practice problems to reinforce understanding.

• Reading the upcoming laboratory document and completing a pre-lab quiz on it.

• Participating in the allocated laboratory session to complete the required simulations, confirm understanding with demonstrators and obtain assessment.

• Referral to textbook where necessary to ensure proper understanding of theory.

• Asking and answering questions on the discussion forum.

• Attendance as necessary at the provided practical session to discuss any uncertainties.

The minimum total expected workload to achieve the learning outcomes for this unit is 144 hours per semester typically comprising a mixture of 3-6 hours of scheduled learning activities and 6-9 hours of independent study per week. Scheduled activities may include a combination of teacher-directed learning, peer-directed learning and online engagement. Independent study may include associated readings, assessment and preparation for scheduled activities.
