EIT-antennas on world-map. Vancouver IEEE-report v2,0

Published: 2015-08-27

Prize money, getting published, and the honour of winning for Georg Wolgast, Hampus Månefjord, Edvard Johansson, Alexander Israelsson and Casimir Ehrenborg, alongside supervisors Anders Sunesson and Jakob Helander.

As mentioned here previously, student team 'Gerhards Grabbar' reached the finals in Vancouver on the 21st of July with their low-power BAN-antenna system and, at the awards ceremony of the IEEE Antennas and Propagation Society, the team was happy to discover that they had won first prize.

Details can be found in a previous EIT news article (search for "Gerhards Grabbar" in the news archive).

When asked if everything had gone according to plan, Edvard Johansson and Georg Wolgast exclaim ”Not at all! We'd reached the finals and thought that had been enough!” ”After having seen the other teams we definitely didn't think we'd win as they were all so impressive”.

The conference is the biggest in the area of antennas and wave propagation, with over a thousand participants, leading us to be curious about how things are done over there. ”Everyone had done measurements on their antenna and presented it in the report, and then during our first day there we did a joint measurement on all antennas using the same measuring equipment”, Edvard tells me. ”The antennas turned out to all be more or less the same strength, but with various individual strengths and weaknesses”.

The next day it was time for the conference, with an exhibition stall, a poster, presentations and four different judges who came up to look and ask questions. ”We had a poster and the whole system up and running where we showed everything off, obviously to the judges' satisfaction”, Georg remarks, pleased. 

And then at the end of the day there was a ceremony with various prices to be handed out. Did the group see or hear anything interesting that could take the technology even further? ”There's was actually a great deal of discussion around potential collaborations for  projects and applications within medicine technology. We've talked to a couple of different people who have since been in contact with us”, they say. 

They didn't know any of the other teams ahead of the competition but after these couple of days spent together the team have gained some new friends and acquaintances. ”We got started pretty immediately with going on trips, eating lunches together and doing lots activities in order to get to know each other better.”

When asked where they see themselves in five years, they seem not quite sure. ”Maybe not medical technology”, one replies. ”Potentially something to do with antennas”, another says. ”The great thing is that at the moment we're just picking courses and we're really starting to choose our specialisations. But BAN-technology, wearables, smart clothes etc are growing areas of interest so there's probably plenty of opportunities.” ”Instead of EKG electrodes stuck to the body, they might be integrated into a shirt with conductive fabric”, one of the supervisors speculates.

From there, our conversation drifts into ”Energy-Harvesting” and supervisor Jakob Helander and Casimir Ehrenborg mention that it may very well be an option for next year's student project. They seem keen to continue taking on fresh challenges that put the students of LTH on the global map. Money? Yes! The 1500 dollar prize money and publication in IEEE Antennas Propagation Magazines student column were an additional bonus that came with the adventure. Travel costs were, by the way, supported by a couple of scholarships and helped along further by the American currency exchange rate. 

EIT says congratulations and GOOD LUCK with your continued studies!

EIT and Huawei initiate collaboration

Published: 2015-08-13


The Department of Electrical and Information Technology (EIT) at LTH initiates a collaboration with the Huawei development unit based in Lund. The joint project is focused on the area of Non-Orthogonal Multiple Access (NOMA), which is one of the techniques being investigated for the fifth generation mobile systems (5G). The collaboration advantage is two-fold.  Firstly it opens up a new area of ​​research for EIT and secondly it contributes to Mobile Heights efforts in strengthening regional partnerships, setting south-swedish mobile industry even more clearly on the map.

From EIT, the work is headed by Associate Professor Fredrik Rusek, who explains about an ongoing recruitment for a postdoctoral researcher, who will receive full funding from Huawei during 2 years. In total, Huawei will contribute with 2.8 MSEK. Huaweis development unit in Lund is responsible for the groups terminal-based 5G platform and those operations are led by Tord Wingren.

NOMA is a recently proposed, unconventional method i order to service multiple mobile phone users simultaneously. Mobile terminals are traditionally separated from each other by dividing either time or frequencies in transmitting through the radio spectrum. In NOMA, multiple users are served simultaneously on the same frequency. The system will provide service to more users but will also result in users disturbing each other. It's a non-orthogonal system. The research approach is focused on eliminating the disturbances in order to fully exploit the NOMA efficiency.

- During most of my time as a PhD-student I worked with non-orthogonal transmission methods. Although NOMA is significantly different, it will be great fun to once again work with these slightly unconventional systems, says Fredrik Rusek.

- It is gratifying that we can start a partnership with a major player like Huawei. It shows that the mobile cluster in Lund continues to be regionally active with new research approaches for the benefit of the mobile industry, says EITs head of department Daniel Sjöberg.

- It is important for Huawei to collaborate with leading universities in mobile communications and we are very happy about this. We hope for more collaboration with Lund University in the near future, says Tord Wingren and Peter Almers, responsible for coordination of the project on Huaweis side.

Lars makes small big things

Published: 2015-06-11


On June 5th, Lars Ohlsson became PhD in Nanoelectronics after having presented how he and his colleagues had been able to demonstrate that a radio transmitter, including antenna, can be accommodated within a cubic millimeter.

Super-computer in the pocket

Lars grew up on a small island in the Småland archipelago but moved to Lund when it was time for university studies, to learn more about ... everything!
 – And in particular the physics and electronics that allow us to walk around with what was recently considered a super-computer in your pocket. There is a lovely mix of advanced theory and sophisticated manufacturing technology.
 – I go back home now and then to enjoy the tranquility and to hunt waterfowl, elk and wild boar, says Lars who also appreciates hikes in Swedish mountains as well as Danish hills.

A natural choice

After finishing his nano engineering studies, Lars took the chance to study for a PhD in the specialist field. "A natural choice taking Lund’s position in the area in consideration", he expresses his choice. The result was successful and is described in the PhD thesis "Compact and Efficient Millimetre-Wave Circuits for Wideband Applications".
 – We have examined what can be achieved just outside the limits of what today is considered as the conventional technology in radio electronics. Electrical components based on nanostructures of III-V materials have been used to create wideband signals at high frequencies, with good efficiency. Furthermore, we have shown that such a radio transmitter, together with its antenna, doesn’t need to occupy more space than a cubic millimeter, says Lars and is a little mysterious about his plans for the future:
 – The plan is to make small big things ...

Flankerad av LTHs rektor Viktor Öwall och professor Ove Edfors skiner LTHs och EITs färskaste hedersdoktor professor Liesbet Van der Perre ikapp med solen i Lundagård. Fredagen den 29:e Maj var det dags igen för årets stora akademiska högtid, doktorspromotionen, där nybakade doktorer, hedersdoktorer och jubeldoktorer hyllas. Liesbet har som högt förtjänt forskare och viktig samarbetspartner i LTHs forskning utsetts till hedersdoktor vid Lunds Universitet. Ring, hatt och diplom plus en massa visdom och lyckönskningar på latin östes över vår akademiska elit och Liesbet fick sin beskärda del.

Dagen innan fick vi lite mer handfast ta del av Liesbets visdom i en mycket välbesökt föreläsning med titeln "Precious bits, sharing the spectrum, on elegant energy". Vi fick bl.a veta att man inte kan lura fysikens lagar och det är ett obestridligt faktum att det finns gränser både vad gäller radiovågornas utbredning och hur mycket man kan skala upp den trådlösa kapaciteten. Det ska enligt Liesbet inte hindra forskarna att ta nya tag och stångas mot framtiden.

"Best Paper" to EIT at ICC 2015

Published: 2015-07-23

Yezi Huang and Eduardo Medeorios with coauthors from Lund University and Ericsson Research received a best paper award with the paper “Mitigating disorderly leaving events in” presented at ICC 2015. The authors presented a solution to the problem that when one modem is turned off during operation, neighbouring modems may temporarily loose their broadband connection. In today’s connected society, this may lead to angry neighbours if it occurs frequently during say popular sports events. This paper solves the disorderly leaving event problem for the newly standardized fibre-DSL system and similar fixed broadband technologies. Two operation modes are proposed to make channel estimation and precoder update unnoticeable to active end-users. In addition, the estimation effort is reduced from K^2 to K, where K is the number of twisted pairs, lowering complexity and cost for the modems.

Butting against the future with his pico-pulses

Published: 2015-05-28


The startup company Acconeer has recently received a large investment for further commercialisation of the technology of integrated microwavecircuits. Acconeer was founded in 2011 and uses solutions that have come about as a result of the research being done at EIT by Lars-Erik Wernersson's research group. We sat down to have a chat with him about the research behind the successful enterprise. 

The group's most important breakthroughs had to do with the very low power consumption and the possibility of generating extremely short, coherent pulses. “Today we're down to 60 ps and we're doing it in 60 GHz areas where we, thanks to the high frequency, achieve very high accuracy”, Lars-Erik says. Coherence is important in this context as it provides access to useful phase information when the pulses propagate and interfere.

Communication turned into radar

When the research first started it was seen as having the potential for communication technology applications. With time, however, the technology became more and more interesting for use with radar, material characterisations and spectroscopy. If communication is ruled mainly by standardisation, radar technology is a more flexible area of research, guided instead by applications and how we use them. Follow the frequency regulations but otherwise use it freely!

“Despite this, we presented and published an article in IEEE Access last autumn which described an experimental communication application with a wireless 15 Gbps link”, Professor Wernersson tells us proudly. “We're increasingly investigating and challenging the limitations of ultra fast wireless technology. Even if Acconeer in this case is a very clear application, we also conduct a great deal of basic research where we will gain new knowledge that can benefit new emerging and innovative ventures to grow in the region.” he adds, with emphasis, “That's why we will continue carrying out this research”.

New tool for analysis

“Another interesting application is, as I mentioned, material characterisation”, Lars-Erik remarks and goes on to describe what it can entail. Characteristics of a material can be studied with the help of pulses that have either passed through or been reflected, as the pulse afterwards changes concerning time, phase, envelope and frequency. “We believe that the technology can be suited to the analysis of gases and liquids considering the rotation transitions at these frequencies”, Lars-Erik says. “In other words, chemists will appreciate this in the future and our short pulses can, for example, give an extremely good time resolution”.

Visions, skills and money give results

Lars-Erik explains the success as being down to a combination of “able doctorate students, visionary ideas and research financiers that place their trust in us in the long-term”. He continues, saying that the combination of hard work and LTH infrastructure are also important ingredients. In addition it's important that doctorates are active educators, ensuring that new good doctorate students are found and recruited.

SSF and VR have been two important financial backers of the research so far and the basic research approach with clear potential for applications has attracted them to stay for the long run. At the start, finance was agreed to on the assumption that the research would have communication applications and a doctorate student from the High-Speed Wireless Centre HSWC was at times assisting with the research. This work was led by John B Anderson

mm-wave collaboration remains

Lars-Erik is careful to pinpoint internal EIT collaborations as extremely important for the success of their research, but also highlights the importance of their cooperation with the Physics institution's nano lab. There is a so called mm-wave group within EIT that spans several research groups and much of the success is due to this forum where various modes of research can meet and thrive. In addition, Lars-Erik is keen to highlight the role of John B Anderson, who has succeeded in bringing about many vital and prestigious collaborations. The HSWC project was, during 2005 to 2010, led by Anderson and managed to get two years additional financing in the shape of a 60 GHz project. The group that was set up then still exists in the shape of the mm-wave group.

Small and close is niche

Lars-Erik believes that many will benefit from the physical smallness in upcoming implementations of their technology. The pulse generators can be integrated on the surface on top of very small antennas and the entire solution needs less than a square millimetre of space.  The range is dependent partly on the output power and partly on whether the work is being done in a closed volume or in free air. The niche is going to be applications with short range needs and Lars-Erik points to car radar as an example, where today there is an issue of “dead” space very near the car. In that space the short 60GHz pulses could act as complimentary technology. 

Robot vacuum cleaners are just one more of countless other potential usages. With imagination and creativity, one can quickly think of more. Wireless communication between units on chip and fast data-dump from phone to hard-drive are another couple of potential applications within communications. 

Commercial interest from the beginning

It becomes clear that this research is both called-for and important when one considers that the first paper that was published on the technology resulted in direct commercial offers from several large  radar manufacturers. The fact that multinational consumer industry in addition has chosen to invest in Acconeer shows that the technology has already picked commercial interests and could have a big economic importance in the future.

Are there health side-effects?

“It's a relevant question”, Lars tells us. The mention of “radar” results in important considerations around radiation etc, but at the same time it is a question of very low effects at around 10dBm (10mW). In comparison, a mobile phone can give off a couple of Watts in continuous effect if it is far away from a base station.

Vacuum cleaners, car radars and communication between chip-buses are just some of the potential future applications of the knowledge that this Lund team is now continuing to develop and refine.

Babak gets first prize with IoT low power design entry.

Published: 2015-05-25

Babak Mohammadi was, after doing the best pitch, awarded with 10000 SEK as the first prize in the “Commercialize your research” course, offered to PhD students at Lund University. There were 21 different projects from all the participants and there was a tight, but exciting competition between groups.

The course itself was about entrepreneurship, innovation and commercialization of research outcomes.  It was a very informative and fruitful course conducted by many workshops on customers, investors, entrepreneur’s views; presentations, drafting a business etc. This helped to see yourself and others’ works with different glasses, which was very constructive.  The course also introduces different methods and tools to support the researchers with commercializing their ideas.

The business plan was based on research outcome, leading to a pitch competition in the last session. Attendees were real entrepreneurs and investors which made it very exciting. Babak presented the idea of a start-up company based on research results in low power design techniques, targeting the future Internet-of-Things (IoT) market. 

Babak Mohamamdi came as a SoC student to Lund university and is a PhD student since 2012.
EIT congratulates Babak!
