Azerbaijan, Baku, Sept. 10 / Trend H.Valiyev /
Deployment of mobile communication services on aircraft board is impractical, Head of the State Radio Frequencies Administration under the Azerbaijani Communications and IT Ministry Aflatun Mammadov told Trend.
The administration's commission comes to such a conclusion. Mammadov believes the issue of mobile communications on aircraft board should be resolved in Azerbaijan in accordance with the international standards.
"In practice, the services and data communications can be delivered in Flight mode. It deals with on-board equipment that supports this feature. But getting an official permission to use the onboard equipment is required. Today, we have already got appeals to obtain a permission," Mammadov said earlier.
The administration received an appeal for permission to provide mobile communication services on aircraft in 2010.
The Administration authorized the use of radio frequency band 1800 MHz for cellular communication on board of the aircraft in November 2009. The Committee said that satellite technologies will be used for calls from board of aircrafts, because it is impossible to use fixed GSM terminals during a flight.
Onboard satellite system does not allow direct contact by telephone with terrestrial base stations in-flight, in connection with which the signal transmission from the mobile phone does not interfere with safe work of the onboard systems.
The aircraft are equipped with base stations, which are turned on as soon as the plane reaches an altitude of 300 meters. With these satellite stations send a signal to the ground, and then routed directly to a network of mobile operators. Communication is automatically turned off during landing.
Today, many airlines prohibit the use of mobile phones because of fears associated with the possibility of problems in the airborne equipment of the liner. The fast moving between cellular networks may lead to a breach of their work on the ground. However, modern technologies allow to operate GSM equipment without interfering with on-board devices of the liner, the administration reported earlier.
