IEEE International Black Sea Conference on Communications and Networking (BlackSeaCom)
The IEEE BlackSeaCom series of conferences are held in the countries surrounding the Black Sea. The goal of the IEEE BlackSeaCom is to bring together visionaries in academia, research labs and industry from all over the world to the shores of the Black Sea. Here they will address many of the outstanding grand challenges that exist in the areas of communications and networking while having an opportunity to explore this exciting and dynamic region that has a rich history.
International Scientific Conference on Information, Communication and Energy Systems and Technologies (ICEST)
The ICEST Conference appears to succeed a series of conferences started from 1963 at the Technical University of Sofia under the name "Day of the Radio". In 1977 the name of the Conference was changed into "Communication, electronic and computer systems". Since 2000 it has become an international conference under the name EIST (Energy and Information Systems and Technologies). The first two EIST Conferences were organized by the Faculty of Communications and Communication Technologies, Sofia and the Faculty of Technical Sciences, Bitola. In 2002 the Faculty of Electronic Engineering, Nis joined successfully the Conference organizers. Again, the Conference changed its name becoming ICEST (International Scientific Conference on Information Communication and Energy Systems and Technologies).
International Conference on Communications, Electromagnetics and Medical Applications (CEMA)
CEMA conference is organized by the Faculty of Telecommunications at TU and Natsionalnia Technical University of Athens. It is an international forum for scientists, researchers and experts (engineers and doctors), which discusses issues in a current interdisciplinary field. The conference is a place for discussion and dissemination of new innovative solutions and research results in communications technologies and their application in medicine.
National Conference "TELECOM"
TELECOM is an annual national scientific-technical conference with foreign participation covering a wide range of issues in the area of state-of-the-art communication systems and networks – from the latest innovations and technical achievements to their successful practical implementation. The aim of the Conference is to create conditions, opportunities, and help the experts and specialists in different telecommunication fields to exchange ideas, knowledge and technical expertise. The discussions will contribute to the creation of new ideas and trends in the development of Bulgarian telecommunications.
