Student Excursions and Workshops

On December 4th, the Spectrum Student Research Group hosted specialists from QWED, Janusz Rudnicki and Łukasz Nowicki.
QWED is a Polish company engaged in developing an electromagnetic simulator, conducting precise material measurements, and carrying out research and development in the field of computational electromagnetic modeling.
Our students had the opportunity to learn about the QuickWave electromagnetic simulator and a device for microwave measurement of materials' electromagnetic parameters. They were introduced to the process of designing microwave devices using the presented software.
The team showcased microwave measurement devices for evaluating the electromagnetic properties of materials, including measurement resonators paired with dedicated software. Additionally, they highlighted the importance of discovering new materials that are lightweight, more durable, and possess suitable electromagnetic properties.

On October 30, third-year Electronics and Telecommunications students had the opportunity to get an up-close look at the elements of a base station managed by @Networks! The visit occurred at a multi-system urban station, where both older-generation radio technology equipment and modern solutions for three operators are located. The most intriguing components for the students included #BBU, #RRU, low-attenuation cables (feeders and jumpers), as well as filters and couplers.

The visit was made possible thanks to Mr. Rafał Kolenda's efforts, and special thanks to Mr. Arkadiusz Wiśniewski for his willingness to host the students!

On October 2-3, members of the KN Spektrum traveled to the Karkonosze Mountains to visit a unique national broadcasting center. At an altitude of 1490 meters above sea level, overlooking the Śnieżne Kotły, lies the Radio and Television Broadcasting Center of the Emitel company. Once a mountain shelter, it is now a facility that utilizes the natural elevation of the terrain to provide residents of part of the Lower Silesian Voivodeship with access to radio and television. During the visit, the characteristics of the broadcasting equipment, the method of signal combining (including a star combiner), and antenna installations were presented. The microwave installations do not ice up because they are in a special room inside the building. Some microwave links transmit signals to seven fill-in stations.

Interesting facts were also revealed: This is the last Emitel broadcasting facility in Poland with a staffed operation; the rest are now unmanned. It is also the only facility powered by two countries: Poland and the Czech Republic. It takes two hours to reach the site in winter by snowmobile from Szklarska Poręba.

Aside from technical highlights, there was time for mountain hikes, a visit to a mountain shelter for an overnight stay, and conversations.

At the open meeting, students had the opportunity to listen to a fascinating lecture about the project that Nokia is implementing together with NASA - namely, the construction of a 4G network on the moon. Participants of the lecture learned, among other things, what is the difference between designing a network that is to operate in space and one that is to operate in earthly conditions, as well as how many questions need to be asked and how many unexpected challenges designers face. After the lecture, the students had the opportunity to see the equipment that is to fly to the moon with their own eyes and ask about any issues they were interested in. The great punchline of this meeting was that dreams are there to be fulfilled, and the living proof of this was the story of our speaker Marcin Szczukiewicz, who has been interested in astronomy since childhood and now has the opportunity to participate in an international space project.

At a lecture entitled "How to provide television to 38 million people?" students had the opportunity to learn what Emitel does, what are the frequency ranges and channel plans for broadcasting, what does radio planning for the DVB-T2 television network look like and how does the construction of broadcasting infrastructure for reforming look like. It was a very fruitful and informative meeting, from which everyone gained the power of knowledge.
We would like to express our sincere thanks to Mr. Paweł Paliszek-Saładyga, who devoted his valuable time to us and wanted to share the vast amount of technical knowledge gained during many years of his career.

The workshop started on October 24, 2022 and will last for two semesters. They are conducted by a graduate of our university, Dr. Eng. Michał Szymczyk Senior Data Scientist, WithSecureTM Certified TensorFlow Developer. During the workshop, participants will learn the topics related to neural networks using the TensorFlow library and will have the opportunity to learn about the enormity of practical knowledge provided by a person from the industry. In addition, a certificate is provided at the end, and for the best, there is an opportunity to get an internship at the renowned company WithSecure dealing with computer and network security.

On October 19, the 3rd year students of Electronics and Telecommunications visited the base station managed by @Networks! The purpose of the visit was to get acquainted with a multi-system city station, where one can compare the old and new technology for implementing a radio track for three operators. Devices enabling the transmission of mobile data were presented. The greatest interest was aroused by such elements of the base station as #BBU, #RRU, low-attenuation cables, and couplers.

Many thanks to Mr. Rafał Kolenda for an interesting presentation of the base station elements and Mr. Arkadiusz Wiśniewski for supporting the development of students!
