摘　　要：简要介绍TD-SCDMA（time division—synchronous code division multiple access）的技术特点，分析其增值业务，特别是基于IMS（IP多媒体子系统）的业务提供能力和种类。Ultra wide band（UWB） is one of the interconnection between mobile and newest wireless communication technologies. The high speed portable devices located in offices and homes can be realized by UWB, so video, audio, and high speed data can be delivered. UWB has bright potential and huge market future, so the competition between several UWB standards has been fierce from the very beginning. This paper discusses the theoretical differences between two main UWB standards, reviews their progress procedures, presents the current market cases for two main UWB standards, and finally predicts their futures.
