中文摘要 | 一九九五年,美國FCC徵詢業者利用Ka-band衛星提供電信服務之意願。十四個公 司先後提出建設及營運 Ka-band 衛星計畫。 毋庸置疑,寬頻衛星通信系統是非常重要的通 信媒介之一。目前部份計畫積極進行中,部份計畫暫停或停止研發。一般相信,大約有二到 三個系統會付諸實現,因此如何選擇有潛力的計畫研究及投資是極重要的課題。本文將分析 報告有潛力的各計畫。 |
英文摘要 | The intention of submitting a proposal for satellite communications services by using Ka-band was called for by the FCC of the U.S. in 1995. The projects of building and operating Ka-band satellite communications were proposed by 14 companies. The broadband satellite communications system is no doubt one of the very important communications media. At present, some projects are progressing but some are already suspending temporarily or even terminated. It seems that only two or three systems can be successfully depolyed. Therefore, how to select a promising project and how to make an investment is really an important issue. Every potential project which has been analyzed by this paper will be reported. |
