翻訳と辞書　辞書検索 [ 開発暫定版 ] スポンサード リンク Connexion by Boeing ： ウィキペディア英語版 Connexion by Boeing Connexion by Boeing (CBB) was an in-flight online internet connectivity service from Boeing. This service allowed travellers to access a high-speed internet connection while on board a plane in flight through a wired Ethernet or a wireless 802.11 Wi-Fi connection. Connexion by Boeing was formed as a separate business unit of The Boeing Company. Major development on the service commenced with a partnership agreement between United Airlines, Delta Air Lines, and American Airlines on June 13, 2001.〔() 〕 Lufthansa joined the partnership as the International launch customer on June 17, 2001.〔() 〕 United, Delta, and American subsequently withdrew from the partnership after the 9/11 terrorist attacks due to the severe drop in airline travel that occurred after the attacks.〔()〕 ==Infrastructure== The infrastructure initially used a phased array Ku band antenna manufactured by Boeing and later a reflector antenna developed and manufactured by Mitsubishi Electric Corporation on the aircraft, leased satellite transponders, and ground stations. The service provided downlink speeds of up to 20Mbit/s and uplink speeds up to 2 Mbit/s. Speed varied due to many factors including resource availability, aircraft location, and regulatory restrictions. A license from the U.S. Federal Communications Commission (FCC) was first received on December 27, 2001. 〔()〕 The United Kingdom subsequently on July 24, 2002 granted Boeing a license for operating over its territory.〔() 〕 Other nations followed in granting operating licenses for the service.〔() 〕 The service coverage included North America, North Atlantic, Europe, the Middle East, Northern Pacific, Australia, and Asia. While other providers have provided in-flight internet, Connexion by Boeing accomplished it first for flights over water. Ground stations were located in Vancouver Island Canada, Ibaraki Japan, Moscow Russia, Littleton, Colorado US, and Leuk Switzerland. Two supporting data centers were also used to control the service. These were located in Kent, Washington and Irvine, California. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Connexion by Boeing」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
