PRELIMINARY SIGN UP: https://njszt.hu/en/webform/gsm-nap-az-informatics-torteneti-kiallitason
DETAILS: The age of the handsets and the NMT-450 exhibition, as well as a live presentation with the organisation of the NJSZT
The first mobile phone service started in Hungary in 1990, which was unique in Central Europe at the time. The construction of the first generation NMT network was followed a few years later by the construction of the second generation GSM network. After more than thirty years, the fifth generation of mobile networks is commonplace, and after the decommissioning of the first generation in 2003, we also said goodbye to the third generation in 2023. We are actively researching the possibilities and implications of reducing and shutting down the second generation throughout the country. We join in these preparatory work with a full-day presentation, where we illustrate the road break of the NTM-450 (.1G.) and GSM (.2G.) systems, and we also highlight the reasons for their statute of limitations. Bring me your old NMT phone and try our sample network.
Location: Neumann Society Historical Exhibition of Informatics, Albert Agora Szent-Györgyi, 6722 Szeged, Kálvária sgt. 23.
PROGRAMME
9:00 , 10:00 GSM Network Measurement Technology , Csaba Sipos (Telecommunication Engineer) and Csaba Szombathy (Szomel Kft., Managing Director and Electrical Engineer) The measurement technique of GSM networks is extremely diverse. In the presentation, they emphasize the importance of frequency accuracy among the many methods and procedures. After that, real tools are used to demonstrate the calibration of a clock signal source in practice.
10:00 , 11:30 NMT and GSM networks , Csaba Sipos (Telecommunication Engineer) The presentation tells us what the main characteristics of the phone generations were, how these networks were built and what we learned from them. We can test the 2G/GSM sample network, frequency jumping and spectrum visualization!
11:30 .12:30 The OFDM Plus Csaba Szombathy (Szomel Kft., Managing Director and Electrical Engineer) The enormous popularity of GSM networks has left many open questions, to which later generations of phones are trying to answer. The presentation tells us what inspired OFDM modulation, which is also the basis for fourth and fifth generation networks.
Lunch break 12:30 , 13:30
13:30 , 14:30 Experiment on the concept of smartphone with a software engineer's eye , Máté Sipos (Private Collector) Comparing the history of smartphone development with marketing systems with the "buta" and "smart" label.
14:30 , 15:00 Security of NMT networks, or how first generation networks were intercepted by Ádám Kiss (SZTE TTIK Institute of Informatics) and Csaba Sipos (Telecommunication Engineer) During the presentation, we can learn how to use modern devices to tap phone calls from the NMT-450 system, and what methods were available during the operation of the system. We also create a testable NMT-450 network!
15:00 , 16:30 The security challenges of GSM networks, or how safe it is to make calls on a second generation network. , Domonkos Tomcsányi (safety expert) During the presentation, we learn about the encryption algorithms used on GSM and their safety.
