摘要
在人们普遍给予全球移动通信系统高技术高效益评价的同时,其高投入高成本所带来的高风险也是不容忽视的。根据市场竞争的观点它同样面临着行业内和行业外多种力量的竞争。持别是近年来地面无线通信的迅速发展对该产业的发展造成了巨大冲击。
While being widely evaluated as a high technology providing high efficiency, the global mobile satellite system entails enormous investment and costs, causing high risks. From the standpoint of market competition, it's facing mixed rivalry from inside and outside of the telecom industry. The skyrocketing growth of the terrestrical wireless communications in recent years has exerted tremendous impact on it.
