����Based on the 4G TD-LTE ��Time Division-Long Term Evolution�� technology�� this book uses the modularity-learning mode and the TD-LTE eNodeB equipment of Datang Mobile Company to give a comprehensive instruction about the hardware structure�� device opening and setting�� equipment maintenance�� etc. through different tasks arrangement. This book has three training parts. The first part is the TD-LTE wireless technology�� the second one is the recognition of TD LTE products�� and the third one is the operating and maintenance of the base stations. Through the learning of the three training parts�� the readers can have a good knowledge of the basic setting and maintenance of a 4G base station�� as well as a sound understanding of the structure installation and testing of the hardware�� and the starting configuration and testing of the base devices. They can understand the basic knowledge involved in running and testing the mobile communication system. The book aims to train the high qualified talents for constructing and maintaining the 4G base station�� and enables them to well grasp the running and maintaining skills for the communication base station and meet the work requirements of the standardized maintenance.����The knowledge of this book is comprehensive�� and it gives a comprehensive introduction to the basic concepts of the mobile communication theory. The book has fully talked about the constructing and maintaining for a 4G base station�� and used the Datang TD-LTE experimental simulation teaching and learning software to illustrate the working processes and the related tasks. Therefore�� the knowledge in this book is more practical.����This book can be used as a professional material for some majors like electronics�� communication or the related ones in vocational schools and colleges�� and also it can serve as a reference and guidance book for professionals or technicians.
