Artesyn Technologies Guo Xiaofeng April 15 reported
Artesyn Technologies informed from ZTE , which has been officially launched for civilian flights " air-ground broadband" mobile broadband data solutions for commercial aviation services or the Internet will be officially launched . This means that the general aviation passengers will be able to meters altitude in the cabin , the same as at home on the ground and connected to the public Internet via 4G .
What is the " air-ground broadband" ? Popular speaking , the ground signal is based on user's mobile phone operator communication base station transmitting antenna on the acquisition, usually transmit mode to landscape , and there is some coverage restrictions , so this is why we will see a certain distance because of a base station. The " air-ground broadband" refers to the launch of the vertical antenna , and the distance is longer , so I can reach meters altitude .
Last year , China's first aircraft equipped with wireless Internet access route to accept passengers experience. According to the relevant parties, was on the plane to build a wireless network , a variety of services in advance loaded on the aircraft in the system , and after the plane reaches the ground , export the data stored on the plane and then imported into the relevant system for processing, actually not true real-time interoperability.
It is reported that as early as February 2013 , ZTE mobile Internet services on testing carried out on civilian flights . Before the launch of the ground-air broadband services , ZTE business requirements and technical characteristics for domestic flights of air-ground communications , provides a complete customized solutions .
In fact, the emergence of early aviation Internet services . In 2007 , ZTE USA Aircell and Qualcomm jointly launched the world's first CDMA-based technology, air-ground broadband system , then the air began to rapidly expand Internet services in the United States. Up to now, the United States nine Airlines flight 1500 has been to achieve a comprehensive air Internet experience.
It is worth mentioning that, with the U.S. ground and air -based wideband CDMA technology is different, in -country testing LTE is based on more advanced technology , that is, we often say 4G.
4G LTE uses air-ground broadband wireless access technology, customized wireless transceiver equipment , erection of ground stations along the flight route or specific airspace to conduct aerial coverage , can provide a maximum bandwidth of 100Mbps over the wireless data for different height levels route of the aircraft, thus more rapid access to the external Internet.
