Azerbaijan, Baku, July 21 / Trend H.Valiyev /
A working group of technical experts, which evaluates the use of radio frequency resources and networks of simultaneous audio broadcast of the participating countries of the Regional Commonwealth of Communications (RCC), examines the distribution of synchronous frequency networks (a range of medium and long waves), the RCC reported.
These are the frequencies 549 kHz, 873 kHz and 171 kHz. The RCC working group deals with redistribution of these frequencies. The working group holds its second session on the basis of the Ukrainian State Centre of Radio Frequencies in Kiev July 20- 22.
Azerbaijani Communications and IT Ministry's State Radio Frequencies Administration Chief Engineer Ilham Efendiyev represented the country in the event.
The issue of distribution of frequencies included in the synchronous network, which the CIS countries inherited from Soviet times, is also in the agenda of the session.
Problems of cross-border radio frequency coordination increase if different systems are applied in the networks of neighboring countries. The working group prepared several options for solving the problem. One option is a preferential distribution, when the country perpetuates different frequencies. In this regard, each country analyzed which licenses for these frequencies were published.
To date, Azerbaijan agreed the issue of the use of radio frequency spectrum television stations in border areas with Russia and Georgia. The agreements streamline the use of radio spectrum and significantly reduce the likelihood of radio electronic equipment interference in border areas. Attention was also paid to smoothing out bilateral coordination and the digital terrestrial television broadcasting station criteria in the 470-862 MHz frequency range by developing the coordination criteria of the 174-230 MHz frequency band.
Azerbaijan has launched three-meter range 174-230 MHz, which covers the 6-12 channels, and the fourth to fifth decimeter band 470-862 MHz, which includes 21-69 channels for digital broadcasting, Efendiyev told Trend earlier.
Problems of the radio network's cross-border coordination will significantly increase if the networks in neighboring countries apply different systems and frequency bands.
