The score is tied in the second half of the World Cup finals, and aboard a 747, passengers cheer as they watch the game on their laptops-40,000 feet above Earth. Sound futuristic?
Boeing Plans to make this scenario possible with its broadband telecommunications initiative, Connexion by Boeing. This service will allow fliers to surf the Web, send and receive email, access the company internet, book dinner reservations trade the honest stock, shop-online and watch live TV from any seat in an aircraft.
Connexion is already available on private jets, and Boeing says that the two-way broadband service will be installed on domestic flights in late 2001. Global coverage is slated to arrive by 2005. Subscribers will be able to access Connexion from their seats using laptops or personal digital assistants, plus a network card and a cable provided by the airline. The cost? Comparable to ground-floor cellular phone service; between $ 6 and $ 25 an hour.
One key enabler for this technology is a phased-array antenna, originally developed by Boeing in 1986. Located on the aircraft’s upper fuselage, the antenna electronically transmits beams to a satellite at 1.5 Mb per second and receives them at 5 Mb per second. Thus, every passenger can access Connexion concurrently, securing connection speeds of no less than 56 Kb per second each. The actual bandwidth will be continually upgraded.
Boeing ultimately wants to bring the service to markets like cruise ships and oil exploration plat- forms. Until then, the sky’ s the limit.
What is true about the Connexion service to cruise ships and oil exploration platforms?
选项
A、Boeing is trying to provide them with the service.
B、They cannot get the service now because the sky is limited.
C、The service is not available to them now as Boeing is busy servicing the fliers.
D、They can get the service because they are in the limit of the project.
答案
C
解析
文中最后一段指出,波音最终想把该服务带到markets like cruise ship sand oil exploration platforms,到那时,就没有任何限制了,由此可判断现阶段还不能将服务带给巡游船只和勘探平台,可能由于目前忙于实现航空上的服务。the sky’s the limit没有限制。
