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.

本書以TD-LTE（Time Division-Long Term Evolution，時分-長期演進）為基礎，采用模塊化教學模式，選取了大唐移動TD-LTE的eNodeB設備，通過具體任務模塊，全面、細致地介紹了基站產品和設備的安裝、關鍵技術、網絡測試、網絡規(guī)劃與優(yōu)化等內容。本書共分為4個培訓模塊，分別為TD-LTE設備認知、TD-LTE關鍵技術、網絡測試以及網絡規(guī)劃與優(yōu)化。通過對這4個培訓模塊的學習，讀者能夠掌握基站設備的硬件結構、維護與測試、網絡規(guī)劃與優(yōu)化等移動通信系統運行與維護中所涉及的基本內容，成為基站建設與維護的高素質技能型人才。這4個培訓模塊的建議學時數分別為12、16、12、16學時。
在傳統技術資料和培訓教材的基礎上，本書對于常見的網絡規(guī)劃與優(yōu)化技能知識點進行了提煉，突出系統思維培養(yǎng)，并將理論講解與任務實例相結合，強化對學生實踐能力的培養(yǎng)。
本書可作為應用型本科和高等職業(yè)院校的電子、通信及相關專業(yè)開展4G通信技術教學的教材，也可作為移動通信、網絡工程專業(yè)人士及工程技術人員的參考書。
