TEK5110 - Building and Controlling Communication Networks using IoT-devices
|News||Lectures on Tuesday afternoon, each autumn, first lecture 24Aug2021|
|by||Josef Noll, Maghsoud Morshedi|
|Abstract||The course provides knowledge on how to build networks, based on radio characteristics, mobile and wireless systems, propagation characteristics. Hands-on experiences with radio communications are used to complement the theory. Likewise, a practical introduction to network monitoring and control is given, both from a theoretical point of view, and from a practical implementation.|
|Objective (max 350 words)|| Objectives to be updated, see info. This course is extending the knowledge of students into the areas of radio communications and should thus be seen as a supplement to high-frequency directional radio links and mobile radio evolutions. Focus in this course will be on radio links for personal and mobile devices covering from some cm (contactless, short range) up to some 10 meters (wireless area). The second half of the course will specific topics in building networks. Topics include: (i), Principles of radio propagation and radio interaction, (ii) Research topics in contactless, short-range and wireless radio networks, (iii) Remote management of wireless networks, and (iv) Evaluation of mobile and wireless communication systems for emerging economies. |
The main goal of the course is to work with scientific literature and analyse advantages and weaknesses of suggested approaches. Students will be asked to select topics, work through the related literature, perform an analysis of the literature, present the results towards the other students and discuss the advantages and shortcomings.This introductory work is mandatory for the participants, as it forms the basis for a home work, analysing selected topics in dedicated areas. The home work will be a report, and contributes to the final grade. Simulations, e.g. network throughput, business aspects or implementation work is the second topic relevant for the final grade. Participants will learn how to evaluate network, and analyse specific radio interfaces for the purpose.

Goals of TEK5110
TEK5110 focusses on gaining experiences in scientific analysis, and presenting the results to the auditorium.
- The first (obligatory) homework will be a paper evaluation and presentation of scientific papers, see TEK5110/List of papers
- Thereafter groups will be established to focus on one of the four topics
- 1. Mobile coverage, capacity and cost aspects of future mobile and wireless networks
- 2. UiO owns the access network, the model of a provider having just an access network, and collaborates with operators on handling the core network.
- 3. Monitoring and management of electricity networks, using Power Tags to monitor the electricity network, and switches to control units
- 4. Internet light for all, providing free access to information for everyone. Examples might be the DigI.BasicInternet.no project on Digital health in TZ.
- 5. Wireless Network management for future services. Management will include monitoring of a real-life wireless installation, and thus allow students to analyse the network impact of services and applications with respect to wireless characteristics.
- We will have an exam contributing to 100% of the total results, reusing the obligatory work listed above.
List of Papers and Group work
The goal of the paper presentation is to learn how to analyse a paper, and present it to the other students. Instead of analysing papers (as e.g. TEK5110/List of papers), we invite you for writing a state-of-the-art for the group work you are doing.
Please see the description for the group work TEK5110 group work - (suggestions and criteria) For this year, I recommend you to form groups of 3-5 people. The goal is to select one of the four scenarios listed earlier, and perform an analysis of the scenario.

Wireless monitoring platform
TEK5110 uses Elastic stack as monitoring platform in order to perform real-time Wi-Fi monitoring. Students can login to https://tek5110.basicinternet.org and use default dashboards to analyze wireless characteristics.

- calculate capacity for W= 200 kHz, 3.8 MHz, 26 MHz, (all cases P/N = 0 dB, 10 dB, 20 dB)
- If the SNR is 20 dB, and the bandwidth available is 4 kHz, what is the of the channel?
- If it is required to transmit at 50 kbit/s, and a bandwidth of 1 MHz is used, what is the minimum S/N required for the transmission?
