第三代移动通信系统(3G)是由国际电信联盟(ITU)提出的工作于2000MHz频段的陆地移动通信系统。现从应用的角度比较了两系统的物理层技术、适用范围等多个方面,为第三代移动通信制式的评估提供了参考依据。
The third generation mobile communication system (3G) is a land mobile communication system proposed by the International Telecommunication Union (ITU) operating in the 2000MHz band. Now from the application point of view of the two systems compared to the physical layer technology, scope and other aspects of the third generation mobile communication system provides a reference for evaluation.
