【资料名称】：UMTS Long Term Evolution (LTE) Technolog

【资料作者】：Rohde & Schwarz

【资料日期】：2008-9

【资料语言】：英文

【资料格式】：PDF

【资料目录和简介】：

非常全面的LTE入门介绍，通俗易懂，而且配合详实的图片和数据，对于LTE各个方面，技术要点，上下行机制，下三层，协议都有描述，是一个overview性质的白皮书，对于初学者或是刚刚接触4G的新手非常有用，网上关于LTE的pre-study性质的总结报告非常多，近一个月的众里淘沙以后，才找到这本众多的所谓overview, introduction, white book中最好的一份资料，强烈推荐。
