The physics and mathematics of signal propagation mechanism in cellular wireless communication system

Monday, August 22nd, 2016

 

 

Speaker: Prof. Tapan Sarkar, Syracuse University, US (12.8., Espoo, Finland)

 

The objective of this short course is to introduce a new physics based visualization of the Electromagnetic wave propagation mechanism in cellular wireless communication systems. We also illustrate from a mathematical point of view that an electromagnetic macro model can accurately predict the dominant component of the propagation path loss in a cellular wireless communication. The reason a macro model can provide accurate results that agree with experiments is because the trees, buildings, and other man made obstacles contribute second order effects to the propagation path loss as the dominant component is the free space propagation of the signal and the effect of the Earth over which the signal is propagating. It is demonstrated using both measurements and an analytical theoretical model that the propagation path loss inside a cellular communication cell is first about 30 dB per decade of distance and later on, usually outside the cell, it is about 40 dB per decade of distance between the transmitter and the receiver irrespective of their heights from the ground. This implies that the electric field decays first at a rate of ρ─1.5 inside the cell and later on, usually outside the cell, as ρ─2, where ρ stands for the distance between the transmitter and the receiver. It will also be illustrated that the so called slow fading is due to the interference between the direct wave and the ground wave as introduced by Sommerfeld over a hundred years ago. All these statements can be derived from the approximate integration of the Sommerfeld integrals using a modified path for the steepest descent method and also using an accurate purely numerical methodology. An optical analog model will be presented based on the image theory developed by Van der Pol to illustrate the mechanism of radio wave propagation in a cellular wireless communication system where the path loss is 30 dB per decade or the field decays as ρ─1.5. This macro model is used to refine the experimental data collection system for the propagation path loss and it is also illustrated how the antenna tilt both mechanical and electrical can be incorporated in the macro model to predict the propagation path loss. Finally, an observation is made on how to further improve the propagation mechanism by observing the second channel from the mobile to the base station. Numerical and Experimental data will reveal that the proposed methodology is a much better way to deploy base station antennas.

FUTURE OF ROBOTICS IN FINLAND SEMINAR 2014

Tuesday, December 16th, 2014

The 2nd Future of Robotics in Finland Seminar was successfully held on 28.11.2014 at Aalto University, organized by the IEEE Finland Joint Chapter of the Control System Society, Robotics and Automation Society and Systems, Man and Cybernetics Society. After drawing both academic and industrial interests in the first seminar last year, this year the main theme was on national robotics roadmap, which attracted near 100 registration (and over 60 participants) from 41 organizations, including 23 companies and key players such as TEKES, Suomen Robotiikkayhdistys ry, FIMA, VTT etc..

The morning session focused on keynote talks, by Olli Venta of VTT, Juhani Lempiäinen of Deltatron Oy, Outi Töytäri of THL, Juha Backman of MTT and Iina Aaltonen of VTT. During the lunch break, the seminar had an interactive session for demonstrations, exhibition and posters from industry and academia. The seminar then continued in the afternoon, where the participants were grouped in specific topics on manufacturing robots, autonomous machines, health and well-being robots, agriculture robots, to identify the opportunities and the focus areas of the national robotics roadmap. The group work results were summarized in the end of the seminar.

The standing officers of IEEE Finland Joint Chapter of the Control System Society, Robotics and Automation Society and Systems, Man and Cybernetics Society organizing the event are Ville Kyrki, chair, Lasse Eriksson, vice chair, Quan Zhou, secretary, and Tapio Pahikkala, treasurer. Ville Kyrki was responsible of the program, and Quan Zhou was responsible of the local organization.

NORCHIP 2014 and SoC 2014 in Tampere

Wednesday, December 10th, 2014

The 32nd Nordic Microelectronics Conference NORCHIP in Tampere on October 27-28 was co-located with the 16th International Symposium on System-on-Chip (SoC), taking place on October 28-29. Two tutorials related to these events were provided by the IEEE CAS Society Distinguished Lecturers. Prof. Ricardo Reis gave a tutorial on Physical Design Automation of Transistor Networks on Sunday October 26. Prof. Geza Kolumban lectured the other one on Monday October 27, entitled Software-Defined Electronics: a new research field for CAS Society. Both gentlemen were also keynote speakers in plenary sessions shared by the two conferences on the overlapping day, Tuesday October 28.

NORCHIP had also another two keynotes: Prof. Leena Ukkonen spoke about controlling artificial or paralyzed limbs by wireless links attached to the human brain, and Prof. Tor Sverre Lande introduced the concept of Constructive Noise. Also in SoC there were another couple of invited talks: Prof. Hank Hoffmann talked about Untapped Opportunities for Manycore Communication Optimization, whereas Vianney Lapôtre presented A Dynamically Reconfigurable Multi-ASIP Architecture for Multi-Standard and Multi-Mode Turbo Decoding.

Together the events attracted well over 100 people to Tampere, out of which about 80 were participating in NORCHIP and 45 in SoC. The engagement of these two conferences was so successful that the conferences decided to fully merge for next year and start circulating under a new (working) title Nordic Circuits and Systems Conference (NORCAS). This marriage will become more than the sum of these traditional events. According to the new Nordic math, 1 + 1 > 2, which will be proven for the first time in Oslo, Norway next October.

IndoorAtlas believes it has found a solution to this problem—by tapping into the magnetic field, which for millions of years has been guiding turtles, whales, salmon, and other migratory animals. Enabled by ultra-accurate positioning, IndoorAtlas believes product-proximity ads could be the next forefront of advertising.

IndoorAtlas originated in the academic world. Founder and CEO Janne Haverinen, a professor at Finland’s University of Oulu, began studying indoor robot navigation in the late ’90s. Noticing that buildings’ magnetic distortions were leading his machines astray, he eventually turned the problem around and focused his attention on the magnetic interferences caused by steel structures. What he found was that the disturbances inside them were consistent, creating a magnetic fingerprint unique to a building. That became the crux of IndoorAtlas, which leverages what Haverinen calls “nature’s GPS”—GPS that requires no infrastructure beyond a smartphone and works where no cellular connections exist.

IEEE MTT-S ambassador visit

Monday, December 1st, 2014

IEEE Finland Section Joint Chapter of AP/ED/MTT hosted IEEE MTT-S Ambassador Prof. Wojciech J. Krzysztofik who gave two lectures in our chapter. Lectures were held in Aalto University on Dec. 1, 2011 and there were 7 people in the audience. First the guest gave a lecture on fractal antennas from 10 to 11 am. In his speech, he discussed fractals in general, showed examples where fractals are found in nature and how different fractal patterns are classified. In the end fractal antennas were discussed. The second lecture given by the guest from 11am to 12 pm was a general presentation on what is IEEE, what benefits it offers for its chapters and what chapters should do to activate its current members and to get new members. After these lectures we visited Microsoft, Aalto University School of Electrical Engineering, and Startup Sauna with the guest. During our lunch we discussed how to develop our chapter and chapter support tools provided by IEEE.ambasador
