ZTE explains how to access the Internet on airplanes
|
Regarding the "Air China provides in-flight broadband Internet access service", it has been confirmed that ZTE is the only supplier of ground base station communication equipment for this ground-to-air broadband system, providing technical and business support throughout the process. Internet access in an airplane is no different from that on the ground. It is reported that on April 16, at a media conference at Chengdu Shuangliu Airport, Air China announced that it has become the first Chinese airline to provide in-flight Internet services and realize ground-to-air Internet dialogue. It marks that China's civil aviation has entered the era of air Internet, which is another historic breakthrough in the development of China's aviation industry. At the same time, the in-flight Internet service was enabled on China Air China flight CA4116 from Beijing to Chengdu and the opposite flight CA4109, successfully completing the first flight and passenger experience test. The highly anticipated in-flight Internet access has finally become a reality. It was learned from the press conference that Air China's ground-to-air broadband is the world's first ground-to-air broadband application based on 4G technology. Gong Yuezhong, vice president of ZTE, introduced that the system uses customized LTE wireless transceiver equipment, sets up ground base stations along the flight route or specific airspace, and covers the high altitude, which can provide aircraft on different altitude routes with a wireless data bandwidth of up to 30-60Mbps. In actual air flight, ZTE allows passengers to access the public Internet by connecting to Wi-Fi, which is no different from the Internet experience in daily life. In more than an hour of experience, passengers used tablets and laptops to chat on WeChat, send Weibo, send and receive emails, and play online games. At the same time, they also realized the Internet experience of high data flow transmission such as online video and watching online movies. During the test, the signal was very stable, exceeding expectations. Passengers access through Wi-Fi In simple terms, in the cabin, the onboard ATG equipment provides passengers with wireless LAN data services, and users can establish a connection with it through Wi-Fi. Outside the cabin, the ground base station and the onboard ATG equipment are connected with LTE technology. Finally, the passengers are connected to the ground Internet to realize Internet services. Gong Yuezhong, vice president of ZTE, said that the aircraft flies at high speed at an altitude of 10,000 meters, and the speed is generally more than 1,000 km per hour, so it is necessary to solve the coverage and access problems of LTE under such specific conditions. In the long-term LTE research and development, ZTE has made breakthroughs and accumulated a large number of key technologies and innovations. For example, the Doppler frequency deviation caused by the high-speed flight of the aircraft, the high-speed switching of the ground base station information, etc. It is precisely because of the breakthrough in technology and deployment difficulties that ZTE's strong R&D strength and comprehensive solution capabilities in ground-to-air broadband services are more evident. In addition, it is worth mentioning that ZTE, as the only system equipment provider for ground base station communications in this ground-to-air broadband test, cooperated with Aircell in the United States to build the GoGo network platform as early as 2007, and currently provides in-flight Internet services for more than 1,500 flights of 9 American airlines. As a winner of Toutiao's Qingyun Plan and Baijiahao's Bai+ Plan, the 2019 Baidu Digital Author of the Year, the Baijiahao's Most Popular Author in the Technology Field, the 2019 Sogou Technology and Culture Author, and the 2021 Baijiahao Quarterly Influential Creator, he has won many awards, including the 2013 Sohu Best Industry Media Person, the 2015 China New Media Entrepreneurship Competition Beijing Third Place, the 2015 Guangmang Experience Award, the 2015 China New Media Entrepreneurship Competition Finals Third Place, and the 2018 Baidu Dynamic Annual Powerful Celebrity. |
