In-flight Internet Attack: China Southern Airlines passenger aircraft use KU band broadband

For a long time, passengers have been sitting on the plane, mobile phones are turned off, and it is difficult to pass the long time, so China Southern Airlines has taken the pace
of research on the Internet in the air.
On June 1, China Southern Airlines revealed that its 10 Airbus A330 passenger aircraft were approved by the Ministry of Industry and Information Technology to implement on-board satellite broadband Internet access verification operation, and used the Asia-Pacific No.
6 satellite for data link transmission
like China Eastern Airlines.
Air China also said on the same day that it has also achieved broadband wireless communication and Internet access using the ground-air base station mode (A TG), and currently has 22 Internet flights
.

According to China Southern Airlines, the 10 Airbus A 330 passenger aircraft of the airline can conduct in-flight Internet service, and the range of routes flown has been further expanded to international routes
.
At present, China Southern Airlines has completed the conversion of 5 of the Airbus A330 passenger aircraft, and it is expected that by June 2016, China Southern Airlines will complete the aerial Internet modification mission
of all 10 aircraft.

China Eastern Airlines has 21 aircraft approved to provide "in the air", all of which are wide-body long-range aircraft
.
Because of its satellite communication technology, China Eastern's "in-flight Internet" can cover international and domestic flights
.
But which routes are still uncertain
.

According to Mi Jisheng, senior engineer of the aircraft engineering department of China Southern Airlines, compared with the SBB, A T G and other technologies previously used by other domestic airlines, the K-U-band broadband satellite Internet access technology adopted by China Southern Airlines and China Eastern Airlines has two outstanding technical advantages: first, the signal coverage is wide; Second, the Internet speed is fast, which can achieve a theoretical peak access speed of 50 megabits per second, which can be called "fiber speed", which is more guaranteed and more stable
than any previous Internet access technology.

Mo Guangwei, an expert at the China Next Generation Internet Research Institute, also said that the business model of the air Internet determines that the charging standard "if it provides a full-service model, the cost is high, and if it is only a single business, then it will be lower"
.
In terms of cost, he said, retrofitting an aircraft to provide in-flight Internet services would cost about $3 million
.
However, according to Zhang Chi, the cost of modifying an aircraft is far lower than this amount, "which is about hundreds of thousands of dollars, and it will not be eight or nine hundred thousand US dollars.
"

In terms of communication costs, Zou Xueyong, secretary-general of the Virtual Business Industry Alliance, said that satellite communication is generally rented data provided by satellites, purchased according to actual demand, and the price of 1G satellite traffic will be higher than the price of
4G traffic.
According to him, at present, the in-flight Internet charges of foreign airlines are generally a few dollars
an hour.
According to previous reports, some experts predict that the domestic civil aviation Internet industry will enter a period of rapid growth, maintaining an average annual growth rate of 30% in the next five years, and the entire air Internet industry will exceed 100 billion yuan
