explodedBulb mobislim_webThe technical platform Semantic Light, a research result from the Mobile Media Services Lab (MMSL) at Wireless@KTH, has a great potential in the creation of interactive light-based effects for professional use. The Swedish national funding agency Vinnova has approved a sum of 500 000 SEK for the team to develop the system into commercial products.

“The system is a technical platform that in an illuminating way connects the possibilities of ICT with innovative solutions with many fields of application” – a quote taken from the Vinnova motivation where the team’s strong business approach and vision is also emphasised.

-During the next year we will develop the Semantic Light platform into a commercial product and launch it on the market, says Professor Zary Segall, (Lead PI)
-We hope to be successful in 2012 and continue with building an infrastructure around it, with the support of application developers and new business creators.

stenMkitalo2In memory of our long-time Guest-professor and fellow-researcher, Östen Mäkitalo, and his great achievements,  TeliaSonera has instituted a scholarship, The Östen Mäkitalo Award. The scholarship will be given to entrepreneurs and scientists who have pioneered the telecom field and who we believe have the same potential as Östen Mäkitalo had – a potential that could change the way we live.


If you know of a telecom pioneer that you think has this potential and should be considered for the scholarship, please let the scholarship committee know. Maybe he or she is the next Östen Mäkitalo!  Mail your suggestions with a short motivation to the committee at

Crowncom new

Crowncom newCrowncom is a prime event on Cognitive Radio and the 2012 edition will be hosted in the Scandinavian pearl of Stockholm, Sweden. The program will feature several Keynote speeches, special sessions, workshops and interesting social events.
Cognitive radio provides a flexible platform that enables the design of systems using the spectrum in radically new ways. How to harness the power the cognition offers, is still an open problem. New schemes for spectrum utilization have to be power efficient, be applicable in a large scale networks, and be able to co-exist with legacy systems. Regulatory rules and conformance test procedures need to be defined to assure the protection of the legacy systems. In order to make the cognitive radio a success story also the market mechanisms and value chains need to be defined. Spectrum trading and dynamic access schemes should encourage efficient usage of the spectrum and collaboration among the stakeholders. This conference provides a venue for researchers to propose new solutions to the technical, regulatory and techno-economical problems related to the cognitive radios.

What next in the Mobile industry?

Posted by: Jenny Minnema   /   0 Comment

antenna towerThe Nordic countries were early in developing and using mobile communication. Ericsson and Nokia had leading roles in the world market but have since then lost these positions. What will be the next turning point?

– The Nordic telecom companies  had a great advantage of being first movers in the development of mobile communications  according to Bengt Mölleryd, a Telecom Analyst and Researcher at PTS ( Swedish Post and Telecommunications Board) and at Wireless@KTH,in an article in Svenska Dagbladet October 23, 2011.

But as mobile communication has become a global phonemna in conjuction with the emergence of a competitive Asian industry in the area and the advancement of the Apple and other IT firms the Nordic dominance have been eroded. Moreover, operators are facing the risk of gradually becoming mere access providers as  Google, Apple, Facebook are driving traffic and establishing its self as preferred suppliers of content and services to the end customer. This is challenging operators position as they are potentially risking to become just bit byte providers.

Ultimately this could have repurcastions on the operator business: Bengt Mölleryd is pointing to the fact that we may have a situation in a couple of years with a single national network in each country. However, it has always been difficult to foresee the future of the telcom market that is so volatile and ever changing.
– Every time we think the industry has reached a mature and stable phase, there is some factor that pops up and changes everything again…. At the moment there is just talk about the smart phones, but that will soon change…

wireless_capacityWireless communication has exploded during the last two decades and today there are more than five billion mobile phone users around the Globe. However, much thanks to the introduction of smart phones, such as iPhones, mobile applications such as Facebook and Youtube, the number of mobile broadband users is expected to surpass one billion before the end of 2011.

Still we are just at the beginning of the wireless revolution. The industry believes that within the next decade the internet of things will take off and that before 2020 there will be some 50bilion “things” connected to the internet, most of them wirelessly. An example of such a system is the Smart Grid that describes the next-generation electrical power system that is built on the increased use of communications and information technology in the future generation, delivery and consumption of electrical energy.

Course Description
This course gives an overview of the basic radio technologies and systems deployed today in order to support this exploding demand for wireless communications. It also provides an overview of the applications and new services that drive the development of mobile broadband. In particular the course examines the various wireless standards used for voice, such as GSM, as well as the ones used for mobile data, including 3G, WiFi, WiMax, HSPA and 4G/LTE. Finally the course reviews some of the various applications that wireless communications can and may support, including apps for mobile broadband and machine-to-machine communications.

Last registration date is November 11.

NRS_logga_genomskThe NRS Foundation (the Nordic Radio Society) has created a 15000 SEK travel stipend to commemorate the Wireless@KTH 10 year anniversary. The stipend will be given to one or two students on Master or Bachelor level as an encouragement for delivery of an excellent Exam Thesis within the scope of  the Wireless@KTH research program. The stipend shall support travel in the form of scientific conferences or study visits to further enhance the students network in the wireless area.  Students and advisors are welcome to submit their applications, consisting of a short motivation letter and the thesis draft (or a link to the document).   Applications should be sent to not later than September 19th.

ChipComputer Sweden, Aug 30: “He gets his students to surpass themselves”
In an article in Computer Sweden Chip Maguire is asked whether Kista is still the place to be in the age of Android versus Iphone.
– I have had 170 Master students in one single course. Good students. That is not the case anywhere else.

One question in the article is if the students today have poorer qualifications when entering higher education. To Chip Maguire it does not really matter. He gives them a task which they think that they can’t solve and then, suddenly, they have built a device and it works!

Two of his former students have made major contributions to the further development of Wireless Communications. Almost twenty years ago he supervised John  Ioannidis who did the pioneering development of Mobile IP, and another student is Joseph Mitola III, who in collaboration with Chip Maguire coined the term ”cognitive radio”.

The future is in sensors
Some ten years ago Chip Maguire, his colleague Mark Smith and their students experimented with so called smart badges. The problem then was that there were no sensors to communicate with. Today, with the extensive use of smart phones this area is of interest again but there is still not a lot of sensors around. So this is what Chip Maguire and his students focus on now. The smart home will require small, cheap and energy efficient sensors. Chip Maguire would like to see sensor systems that adapts to where people are, if they are active or not etc, with the vision of saving energy on a large scale.
