Introduction - History of Department

The Department of Telecommunications was established in 1962 by establishing a regular study of electrical engineering within the Technical Faculty in Banja Luka and then the first generation of students in the Department of Electronics and Telecommunications was enrolled. A very significant contribution to the initial phase of the Department's development was given by: Prof. Dr. Aleksandar Damjanović, Prof. Dr. Tomislav Tomić, Prof. Dr. Georgije Lukatela, Prof. Dr. Milan D. Savić, Prof. Dr. Ilija Stojanović and Prof. Dr Velimir Jovanović. Special significance for development of the Department was given by Prof. Dr. Đemal Kolonić, the best student of the first generation (1962-1966), studies in electronics and telecommunications and the first graduate engineer at then the Technical Faculty in Banja Luka. Prof. Dr. Đemal Kolonić was employed at the Department since 1966, first in the title of assistant, then after 1974 as a docent, and since 1984 as a professor. In addition to being for long-time the Head of the Department of Telecommunications, he was also a Vice-Dean and Dean of the Faculty of Electrical Engineering in two electoral mandats.

In the realization of teaching and scientific activities at the Department in the initial period was very important very good cooperation with the Faculty of Electrical Engineering in Belgrade and the Faculty of Electrical Engineering in Zagreb, and later with the Faculty of Electronic Engineering in Nis and the Faculty of Technical Sciences in Novi Sad.

Activities of the Department

Educational activities at the Department of Telecommunications are realized in the framework of classes in BSc, MSc and PhD studies, which cover wide areas of wired and wireless telecommunication technologies. The subject contents and teaching process are adapted to the needs of the telecommunications market for the narrower specialties and different interests of future engineers. The focus of the educational activities sre the fundamental principles of telecommunications, network architecture and communication protocols based on IP technologies, wireless sensor networks, mobile positioning techniques, design and implementation of radio frequency circuits and systems, planning and optimization of radio networks, electroacoustics and processing of audio signals, etc.

In addition to educational activities, the Departments's activities include research in the following areas:

  • conventional wired and wireless telecommunications,
  • antennas, radio-commmunications and modern RF/Microwave engineering,
  • mobile wireless communication systems of the next generation,
  • positioning in wireless telecommunication networks,
  • voice communications,
  • nano-scale and molecular communications,
  • sensor networks and Internet of Things protocols and applications.

Lecturers and associates at the Department were engaged in a number of scientific and research projects realized in cooperation with business and telecommunication companies, as well as within WUS and TEMPUS projects in the past period.

Laboratories

Within the Department of Telecommunications there are three laboratories: radio-communication laboratory, laboratory for microwave technology and electromagnetic compatibility, and laboratory for multimedia telecommunications. In the past few years, with the financial support of the Ministry of Science and Technology of the Republic of Srpska, EU's ERASMUS+ programme and the company "Čajavec" were acquired the key laboratory instruments(spectrum analyzers, RF network analyzer, impedance analyzer, logic analyzer, audio analyzers, signal generators, etc.), which created the conditions for scientific research work and higher quality of the laboratory exercises in the field of radio communications and microwave technology. By acquiring Faraday's cage, the basic precondition for forming a laboratory for electromagnetic compatibility has been created. The Multimedia Telecommunications Laboratory was established in 2003 with the financial assistance of the Telecom of Republika Srpska. Laboratory equipment enables research in the field of processing of multimedia signals (algorithms, standards, transmission, quality of services), as well as simulation of different network environments and transmission technologies of modern telecommunication systems. An anechoic room (deaf room) has recently been located within the Department, where it is planned to perform part of laboratory exercises in the subject Electroacoustics and audio signal processing. Research fields in this domain are automatic speech recognition, primarily whispers (continuous speech, isolated words), automatic recognition of speech emotion, automatic recognition of speakers, testing of the robustness of automatic speech recognition systems, traffic noise testing, etc.
