China Eastern Airlines opens Beijing-Shanghai route to WiFi: mobile phone still unavailable

Passengers are experiencing wifi on the CA4116 flight from Beijing to Chengdu on April 16. Airline reminder: The computer network supports mobile terminals such as tablets and laptops, and does not support mobile internet access via WiFi. Tomorrow, passengers on the Beijing-Shanghai Airlines flight, you may be on the plane to brush Weibo, play micro-letter. Tomorrow up to the end of September, China Eastern Airlines will be on the Beijing-Shanghai route for commercial test flights, the official Take-off air interconnection flights, the estimated million meters high speed will reach 32M. Earlier, Southern Airlines had announced that it would officially promote the internet on some flights in July. Airlines have warned that passengers can only use computers, ipads and other mobile devices through WiFi access, aircraft still prohibit the use of mobile phones. The maximum bandwidth on the flight is 32M it is learned that China Eastern has been approved to use the Asia-Pacific sixth satellite Ku-band satellite high-speed broadband access, and will be on the Beijing-Shanghai route for commercial test flights. In accordance with the technical requirements, China Eastern completed the aircraft registration number for the B-5903 Airbus Airbus luxury wide-body aircraft equipment modification, and will be tomorrow with the Chinese Telecom (52.02,-0.63,-1.20%) to open the mainland's first official take-off of the air-connected flights. According to the introduction, Ku-band data communication can achieve theoretical communication speed of 50M, but because of the loss in the signal transmission process and other factors, so the actual satellite and aircraft communication between the maximum bandwidth of 32M. At the same time, in fact, the network speed experience, but also by the ground network speed, site individual differences and other factors affect. To ensure the Internet experience of different travellers, the system will also dynamically adjust the bandwidth allocated to each passenger, so as to prevent individual passengers from using high flow applications to affect the Internet experience of other travellers. According to the previous internal flight test, according to the A330 model most of the passengers about 200 people at the same time online, visitors can web browsing, micro-letter interaction, the air shopping. If 40-50 people surf the Internet at the same time, in addition to achieve the above functions, but also to complete the Space video link, network video playback functions. China Eastern also said that passengers on the aircraft on the Internet must conform to the real-name principle. Each passenger will get a captcha before taking off. This verification code is related to the document information, the seat number of the machine and so on. Through the verification code login, in order to achieve air access. It should be noted that as a result of satellite communications, data from the aircraft to the Earth station, and then from the ground station to return data, need to go through nearly 100,000 km, while the satellite communication network link is far more complex than the ground network, so the initial landing on the aircraft, the site may occur about one second or so delay. Turbulence severe network or close apart from China Eastern Airlines, the other two domestic airlines-Southern airlines and air services are also on the Internet. Southern Airlines recently announced that it will officially launch a broadband WiFi internet verification flight on some of its flights in July. Southern Airlines use the same technology as Eastern Airlines. and Air China on November 15, 2011The first flight of a wireless LAN was carried out, and Air China had a broadband Internet flight experience this April. Air China said that through these experiments, when the condition is ripe, it will provide aerial Internet service on the corresponding fleet. is the Internet safe on the plane? According to the introduction, the transformation of the aircraft through the most stringent testing, can ensure that the Internet equipment will not affect aircraft navigation equipment, thereby ensuring aviation safety. In accordance with the requirements of the security of flight safety and business supervision policy, satellite communications and WiFi in the cabin will be automatically opened after the plane has climbed to 10000 feet, or about 3000 meters, to allow passengers to surf the Internet. When the plane drops, the height below this value, the above device will automatically shut down. At the same time, in order to ensure the safety of passengers and aircraft, the above equipment may also be closed automatically when there is a severe turbulence in the air stream or other conditions which may affect the safety of flight and communication in the event of continued provision of network services. According to the introduction, the use of communications satellite Ku-band transmission signal for the open space interconnection is currently the mainstream of a technical way, can cover the world except the north and south poles of the vast majority of the region, not by the route and topography, data bandwidth is large, network operation is more stable, can be applied to the At present, the global use of more widely, its representative company for the United Airlines, the United States Southwest Airlines and Lufthansa and other German airlines. Mobile phones are still not available to use WiFi on the plane to pay? China Eastern said that regardless of the technical model, the implementation of open space interconnection services on the aircraft, the cost is more expensive, much higher than the cost of terrestrial Internet services. However, in order to obtain data and feedback passengers, in the commercial testing phase, China Eastern Airlines and the Chinese telecom temporarily do not charge passengers fees. Does this flight mean that air surfing can be spread across China's civil aviation industry? At present, the air Internet in mainland China is still in the initial stage, the corresponding policies and regulations, business standards need to be gradually established and improved. Therefore, after a rigorous certification and review, the national competent authorities allow the Eastern Airlines and China Telecom to use the B-5903 aircraft modified by the Eastern airlines, to carry out test flights on the Beijing-Shanghai route, to collect feedback opinions from passengers, to further verify, adjust, optimize the network operation quality and improve the service flow, and the accumulation of operational data for further development of business standards, design control procedures to provide the basis. In addition, the airline also reminded the computer network to support the mobile terminals such as tablets and laptops, but still do not support mobile Internet, passengers in the aircraft, the need to turn off the mobile phone.
