Azerbaijan, Baku, Sept. 14 / Trend H.Valiyev /
The Azerbaijani State Radio Frequencies Administration signed an agreement with the Swiss airline to use the frequency resources for the provision of mobile services on board the aircraft, Administration Head Nadir Sadikhov told. The company itself was not named.
Sadikhov said according to the international practice, the use of GSM base station and the frequency resources for the provision of mobile services on board of the aircraft when flying through the airspace of Azerbaijan requires registration in the administration.
The Administration authorized the use of radio frequency band 1800 MHz for cellular communication on board of the aircraft in November 2009.
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.
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," Sadikhov said.
The administration is also considering the appeal of the American companies to record the frequency resource and onboard equipment.
