Access and Transport Networks

The course covers technologies and concepts which are used in access and transport networks typically applied in telecom operator networks. General principles are described, linked to real-world deployments, and a selection of specific technologies and concepts are covered in depth.

A. General:

• Architecture of communication networks.
• Functions: transmission, synchronization, access, multiplexing, routing, switching, signalling, mobility.
• Applications and their requirements to Quality of Service- Capacity and transmission characteristics of different media.

B. Wireless Access:

• Radio as communication medium (frequency band, modulation, multiplexing, antennas, coverage, propagation).
• Medium Access Control - Wireless LAN.
• Mobile network access: GSM, UMTS, WiMAX, LTE, etc.
• Wireless personal networks and IoT.

C. Optical Transport Networks and Fixed Access:

• Optical components, fixed communication medium (characteristics, availability).
• Fiber based access.
• Introduction to optical switching and optical transport networks (OTN).
• Carrier Ethernet.
• Introduction to optical circuit switching (OCS).

A. Knowledge:

1. To understand which components, functions and principles are required for the realization of wireless access and optical transport networks.
2. To understand a selection of the most applied wireless and optical network technologies.

B. Skills:

1. To be able to reuse ideas, technologies and components of previous networks to design and build new networks.

C. General competence:

1. To understand the design of public communication networks and which aspects lie behind particular technological choices.

The course contributes to almost all UN sustainable development goals (since efficient communication/networking is a fundamental need for all non-local cooperation) but maybe in particular:

• Goal 4 "Ensure inclusive and equitable quality education and promote lifelong learning for all" ("Infrastructure solutions that bring Internet access; downloadable digital content; digital platforms and remote learning programs").
• Goal 9 "Build resilient infrastructure, promote inclusive and sustainable industrialization and foster innovation" ("Industrial Internet of things (IIoT); 5G network connectivity to enable industrial automation and the associated efficiency gains; Cross-team collaboration opportunities enabled by digital platforms").

The course applies a combination of traditional lectures and team-based learning methods and activities, up to two assignments, which together with Readiness Assurance Tests (RATs) compose the portfolio.
