An interview with Emad Farouk Ibrahim, who is doing his licentiate thesis at Luleå University of Technology.
Tell us more about what you researched?
My licentiate thesis is about reconfigurable intelligent surface (RIS) which is a new technology that has gained a lot of attention during the last few years. A RIS is a thin planar array that consists of multiple reflecting elements, each of which is connected to a tunable chip and can induce a controllable reflection coefficient to the incident signal. The RIS is a nearly passive unit as it only leverages the reflection on its elements and it does not consume any power for transmission. The advantage of the RIS arises in creating energy-efficient smart radio environments wherein the wireless channel becomes an optimization variable. In this thesis, we study some of the potential applications and deployments for the RIS in wireless communications.
How did you come to choose this particular area?
It started by investigating a fundamental problem that usually occurs in MIMO communications when it is deployed in line-of-sight environments where spatial multiplexing becomes unattainable. There is a classical solution for this problem by deploying repeaters to enrich the wireless channel with multipath. However, this solution is not energy-efficient due to the power consumption of the repeaters. So, alternatively, we deploy distributed RISs to synthesize a sort of multi-path propagation. From this time, we see the advantages of the RIS as a new player to the whole communication process which may provide several solutions for the limitations that exist in the wireless channel and emerge new applications that have never existed with classical wireless communication systems.
What has been the biggest challenge and discovery?
We faced many challenges during this thesis. However, all of them were pleasant to us as overcoming them makes us one step closer to developing new solutions and applications. Moreover, I believe that our biggest discovery relies on the RIS ability to control the polarization state of the reflected waves. Since we develop a novel application depending on this RIS function. In this application, the RIS acts as an access point for information transfer where it alternates the polarization state of the reflected waves to encode the information data.

On the 22 January 2020, Arctic 5G Test Network held a SME workshop in Oulu, Finland.
The workshop was about 5G cross-boarder testing opportunities and was open for companies to attend. Swedish organizations had the possibility to participate via a live streaming distance link from Luleå to receive the latest information on collaboration and testing possibilities. During the meeting, the 5G research and development was discussed as well as cross-border 5G test opportunities for corporations.
Moreover, Mats Nordberg from Ericsson Research held a presentation about their resent 5G test in the Luleå 5G test environment. They have built a RC car to be able to evaluate real-time performance of a 5G network with demanding video. The relatively high speed of the RC car makes it possible to test the limits of different positioning techniques. This also provides the opportunity to display various 5G technologies such as QoS, slicing and beam forming. The RC car will be used to evaluate performance in 5G installations in mines.
There were 39 participants, in Oulu, Luleå and also watching an online stream.
You can find the presentations and the video stream from the workshop here:

Kick-off for Arctic 5G Test Network
On October 9, 2019, there was a kick-off meeting for the new project Arctic 5G Test Network.
The project aims to connect 5G test networks in Oulu, Finland and Luleå by connecting them and participating in an active collaboration and creating an Arctic node within 5G through collaboration between universities, large ICT companies and SMEs. This enables cross-border testing and increases the overall test function in 5G networks. In addition to scientific experiments, the industry is also planned to benefit from the improved testing environment.
Karl Andersson is assistant professor and the one from Luleå University of Technology who leads the project.
- I am glad that we can now practically get started on the joint work and connect the research team from Oulu with us in Luleå, says Karl.
-We have a good foundation to stand on both in Finland and Sweden and now we hope to show that 1 + 1 will be more than 2 in a cross-border project, Karl continues.
-The Kick-off meeting has shown that we have many common interests and that there is very good potential for us to be well ahead in, for example, sparse rural communication for 5G, concludes Karl.
On the 21-22 January 2020, Arctic 5G Test Network held a project meeting in Oulu, Finland.
The meeting evolved around work package discussions including use cases, automated driving and smart healthcare. It also included Horizon2020, smart specialization, testing ideas with industry and academia dialogues. There was also a steering board meeting taking place as well as future meeting preparations.
Moreover, the meeting continued with a visit to Oulu’s 5G test network site.
