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(shí)分-長(zhǎng)期演進(jìn)）為基礎(chǔ)，采用模塊化教學(xué)模式，選取了大唐移動(dòng)TD-LTE的eNodeB設(shè)備，通過具體任務(wù)模塊，全面、細(xì)致地介紹了基站產(chǎn)品和設(shè)備的安裝、關(guān)鍵技術(shù)、網(wǎng)絡(luò)測(cè)試、網(wǎng)絡(luò)規(guī)劃與優(yōu)化等內(nèi)容。本書共分為4個(gè)培訓(xùn)模塊，分別為TD-LTE設(shè)備認(rèn)知、TD-LTE關(guān)鍵技術(shù)、網(wǎng)絡(luò)測(cè)試以及網(wǎng)絡(luò)規(guī)劃與優(yōu)化。通過對(duì)這4個(gè)培訓(xùn)模塊的學(xué)習(xí)，讀者能夠掌握基站設(shè)備的硬件結(jié)構(gòu)、維護(hù)與測(cè)試、網(wǎng)絡(luò)規(guī)劃與優(yōu)化等移動(dòng)通信系統(tǒng)運(yùn)行與維護(hù)中所涉及的基本內(nèi)容，成為基站建設(shè)與維護(hù)的高素質(zhì)技能型人才。這4個(gè)培訓(xùn)模塊的建議學(xué)時(shí)數(shù)分別為12、16、12、16學(xué)時(shí)。
在傳統(tǒng)技術(shù)資料和培訓(xùn)教材的基礎(chǔ)上，本書對(duì)于常見的網(wǎng)絡(luò)規(guī)劃與優(yōu)化技能知識(shí)點(diǎn)進(jìn)行了提煉，突出系統(tǒng)思維培養(yǎng)，并將理論講解與任務(wù)實(shí)例相結(jié)合，強(qiáng)化對(duì)學(xué)生實(shí)踐能力的培養(yǎng)。
本書可作為應(yīng)用型本科和高等職業(yè)院校的電子、通信及相關(guān)專業(yè)開展4G通信技術(shù)教學(xué)的教材，也可作為移動(dòng)通信、網(wǎng)絡(luò)工程專業(yè)人士及工程技術(shù)人員的參考書。
