Azerbaijan, Baku, Oct. 13 / Trend A.Akhundov /
A working group on the study of use of the radio frequency networks of the simultaneous audio broadcast of the Regional Commonwealth of Communications (RCC) in the medium and long-wave (MW / LW) will prepare the draft version of frequency bands MW / LW band, the chief engineer of the State Radio Frequencies Administration , Ilham Efendiyev, has told Trend.
The matter is the 549 kHz, 873 kHz and 171 kHz frequencies that should be coordinated so that the transmitters used by one country do not to create interference with other broadcasts.
Preliminary versions of frequency bands MW / LW band will be prepared during the third working group meeting to be held in Moscow on Oct.19-22. The State Administration of Radio Frequencies under the Azerbaijani Communications and IT Ministry will represent the country at the event.
According to Efendiyev, the meeting is expected to determine the approaches and criteria to eliminate interference, possibility of realization of the feasibility of the technical proposals and their approval.
Earlier, RCC commission for satellite communications, television and radio broadcasting has recommended that RCC member countries develop criteria to redistribute long and medium wave radio frequencies across the broadcast network.
The working group is charged with large-scale work to define the technical and financial criteria for such coordination.
The most acceptable criteria for coordination is to reduce the power of transmission devices and change the direction of antennas.
The level of transmitter power for the frequency range of 549 MHz has not been used yet, but it was checked with the Azerbaijani Radio Frequencies Administration. It was 60 kilowatts and Azerbaijan may reduce the power by 50 kilowatts, Efendiyev said.
"Another aspect is to study the possibilities for changing the configuration and coordination of the antenna without interfering with the ether of other countries," Efendiev said.
