Pursuant to the Law on Electronic Communications, the Regulatory Agency for Electronic Communications and Postal Services (RATEL) shall be responsible for the RF spectrum monitoring on the entire territory of the Republic of Serbia, with its Monitoring Section and Monitoring and Measurement Centers being the organizational units tasked with these activities within the Agency.
Monitoring of the radio frequency spectrum includes verification of broadcasting parameters of the radio stations operating on the basis of issued licenses for the RF usage or under the general authorization regime, detection of the nature and location of the illegal radio emission sources and sources of harmful interferences, coupled with legal measures for the removal thereof, verification of requirement compliance regarding the broadcasting of radio signals agreed upon in coordination agreements signed with other countries, spectrum usability testing in specific radio frequency bands, as well as other activities needed to ensure unhindered operation of all radio communications devices and systems. Monitoring results are shared with other RATEL services and sections tasked with planning and harmonization of the RF usage, thus completing the process of spectrum management activities.
RATEL’s RF spectrum monitoring system is comprised of two manned Monitoring and Measurement Centers in Belgrade and Niš respectively, four measurement vehicles equipped with special measuring devices and telescopic antenna masts, and a system of remote controlled sensor stations installed in Belgrade, Niš and Novi Sad. The Monitoring Section teams, in addition, use various portable measuring equipment enabling measurements in radio frequency bands up to 90 GHz.
In 2017, the construction of remote controlled monitoring and measurement stations for low intensity signal measurements and geolocation of the emission sources in broader areas began. The completing of this system will enable permanent RF spectrum monitoring on the entire territory of the Republic of Serbia.
During phase one, four such stations were built and put in operation in the mid 2018. Phase two, by 2020, included construction and equipping of another twelve stations, thus enabling continuous monitoring on a broader national level.
In the following period, an expansion of the system of remote controlled monitoring and measurement stations is foreseen, including installation of a number of less complex sensor stations intended mostly for urban areas. Integration of the two types of stations into one RF spectrum monitoring system, with a common software platform access to various measuring equipment, will introduce an even more efficient monitoring of the RF spectrum usage.
