Telecommunication systems

Our researchers are specifically qualified for evaluation and handling of IT architectures, mobile multimedia, web services, as well as virtualized environments, such as cloud computing and cloud networking.

Without telecommunication systems the world stops. Airplanes and boats must be able to communicate with air-traffic controllers and vessel traffic services, respectively. The GPS navigator in the car needs updated traffic information in order to suggest the best route. The trading on stock markets around the world demands robust and fast telecommunication systems. The same can be said about on-line shopping.

In the near feature, additional critical systems will be brought online and connected together, such as manufacturing systems in factories, patient medical data, infrastructure for remote surgery, lamps and not the least refrigerators – the typical use-case for the Internet-of-Things. At the same time, as different types of systems become connected, the sheer amount of components and the resulting complexity are themselves a challenge. Future services and systems are going to rely even more on simpler, better and more efficient telecommunications systems, all in accordance with the “plug-and-play” paradigm.

Given these upcoming challenges, the aim of the research is to:

Contribute to the body of knowledge explaining how components in telecommunication systems function and interact with each other;

Create methodologies and models for these systems; and

Suggest architectures and optimizations of systems and components that maximize efficiency, performance, resource utilization and costs in a sustainable way.

Smart solutions require smart support from information and communication technology (ICT), which means that the data must be transported optimally from the point of view of performance, cost and sustainability. On this basis, the research aims, on one hand, to design future-proof system and associated architectures; on the hand, measure, model and analyse system properties while taking into consideration user-experience performance and resource utilization; and last but not least, enhance the system attributes and capabilities. These activities are the primary means to fuse the subject telecommunication systems with the focus areas at BTH: applied IT and sustainable development. This means that more affordable and environmentally friendlier services become available for the general public.

Research specialisations

Performance and efficiency issues in telecommunication systems

BTH´s research in telecommunication systems focuses on performance and efficiency issues. Our researchers have specific expertise in the evaluation and treatment of mobile multimedia, web services and virtual environments such as cloud computing and cloud networking. The research team has access to both network and radio communications lab with equipment that allows advanced experiments, measurement and emulation capabilities.

Quality of experience

Some of the research focuses on quality of experience and tries to build bridges between objectively measurable values and subjective user reviews to enable a continuous quality monitoring without burdening the user. Moreover, research is conducted in future communication networks.

Examples of projects

CONVINcE (Consumption OptimizatioN in VIdeo NEtworks)

CONVINcE addresses the challenge of reducing energy consumption in IP-based video networks with an end-to-end approach: from the main end where the content is encoded and streamed to the terminals where they are consumed, through the use of Content Delivery Networks (CDN) and core and access networks. Energy conservation is a key challenge for the European Union. CONVINcE contributes to overcoming this challenge by helping European businesses develop new solutions and products that reduce our energy footprint from video transmission networks. These solutions also reduce energy consumption in Europe and thus contribute to making the European industry in this field more competitive.

Euro-NF (Networks of the Future)

Euro-NF (Networks of the Future) is a European excellence network that focuses on future networks, and works in close collaboration with the ICT domain within the European Commission and its Future Network Unit (a BTH researcher in telecommunications systems is part of the management team of the Future Internet Cluster). Euro-NF comprises 35 partners from 16 countries. BTH is represented in the steering committee and is in charge of activities such as the visionary work, the Future Internet Cluster workshops, and the next Euro-NF annual conferences (NGI 2012, Karlskrona, June 2012). At the Future Internet Assembly in Budapest in May 2011, BTH held an ICT and sustainability seminar which was highly appreciated.

QuEEN (Quality of Experience Estimators in Networks)

QuEEN is a European research project which aims to assess the user experience through measurements performed within communication networks, which is a priority for operators. In addition to measuring and modelling the relationships between measurements on a network and application level with user reactions, the project will also focus on financial aspects, such as pricing and payment strategies. The project includes 20 partners from seven countries. The Swedish consortium consists of Acreo in Kista, BTH (as one party), Ericsson Karlskrona and info24 in Kista, and is partly funded by VINNOVA.

QuEEN was approved by the European Celtic organisation and is partly funded by VINNOVA.
