During the frequency assignment process it shall be avoided that the radio stations to be licensed cause harmful interference to the radio stations operating in Hungary or in other countries and for which ones the frequency has already been assigned. Furthermore, the radio stations to be licensed shall be protected against the radio stations operating in the band concerned if their service category enable this. For this purpose, during the frequency-assignment procedure – depending on the specific wave-propagation features of frequency, radio service given and the characteristics of the radio stations to be licensed – coordination may be required.
Planning-purpose data provision provided by Defence and Law Enforcement Frequency Management Directorate (VRFGI/NARFA HU) on user’s request, includes the scope and format of the data to be provided for the case of international coordination that might be necessary.
In pursuance of frequency assignment procedures, national and international coordination are carried out by the Office.
Before the completion of the international coordination process, on the request of the licensee, VRFGI/NARFA HU may optionally issue individual licence, which may be modified or withdrawn depending on the result of the international coordination.
In accordance with the authorization under Article 6 of the Radio Regulations, the administrations may conclude special bilateral or multilateral agreements and international coordination agreements.
Hungary has concluded a number of bilateral or multilateral international special agreements, from which the most significant is the HCM Agreement. It has concluded with participation of 17 countries, including Hungary, relating to the land mobile service using the frequency band 29.7 MHz - 3400 MHz and the fixed service using the band 1350 MHz - 43.5 GHz.
Preferred or preferential agreements for the equitable distribution of the frequency band or channels in the border area between the administrations concerned ensure equal spectrum access in different frequency bands.
The agreements include the deadline of submission for the coordination statements and dispose of the procedure to be followed in unusual cases.
