Based on TD-LTE (Time Division-Long Term Evolution), this book adopts the modular teaching mode and applies the eNodeB equipment of Datang Mobile TD-LTE. Through the specific tasksin each module, it presentssuch contents as base station products, equipment installation, wireless technology, network testing, network planning and optimization, etc. in a comprehensive and detailed way. This book is divided into four training modules, namely, TD-LTE Equipment Cognition, TD-LTE KeyTechnologies, Network Test, Network Planning and Optimization. After learning the four training modules, learners can master the basic contents involved in the operation and maintenance of the mobile communicationssystem, such as the hardware structure, maintenance and testing of the base station equipment, network planning and optimization. This book aims to cultivate high-quality skilled personnel who master the testing and optimization skills of base station and meet the requirements of standardized field maintenance operation.

On the basis of traditional technical resources and training materials, the common knowledge points about network planning and optimization are extracted, andsystematic thinking is highlighted.With strong operability and practicality, the chapter layout of this book is based on the working process and practical tasks. Besides, this book explains the basic concepts of mobile communication in a simple way, comprehensively introduces the process of construction and maintenance, test and optimization of the 4G base station, and carries out network test and analysis with Datang Outum software.

This book can be used as the textbook of 4G communicationtechnology courses for electronics, tele- communicationsand related majors of application-oriented universities and higher vocational colleges, as well as the reference book for mobile communications, network engineering professionals and engineering technicians.

本书以TD-LTE（Time Division-Long Term Evolution，时分-长期演进）为基础，采用模块化教学模式，选取了大唐移动TD-LTE的eNodeB设备，通过具体任务模块，全面、细致地介绍了基站产品和设备的安装、关键技术、网络测试、网络规划与优化等内容。本书共分为4个培训模块，分别为TD-LTE设备认知、TD-LTE关键技术、网络测试以及网络规划与优化。通过对这4个培训模块的学习，读者能够掌握基站设备的硬件结构、维护与测试、网络规划与优化等移动通信系统运行与维护中所涉及的基本内容，成为基站建设与维护的高素质技能型人才。这4个培训模块的建议学时数分别为12、16、12、16学时。
在传统技术资料和培训教材的基础上，本书对于常见的网络规划与优化技能知识点进行了提炼，突出系统思维培养，并将理论讲解与任务实例相结合，强化对学生实践能力的培养。
本书可作为应用型本科和高等职业院校的电子、通信及相关专业开展4G通信技术教学的教材，也可作为移动通信、网络工程专业人士及工程技术人员的参考书。
