**课程名称：** 2G、GPRS、EDGE 基础 **课程概述：** 本课程由拥有十三年电信行业经验、曾任职于华为、诺基亚、爱立信，并在埃及和沙特阿拉伯拥有十年电信教学经验的 Emad Salem 讲授。课程将深入讲解第二代（2G）无线信号在基站与移动台之间的传输原理，是学习3G、4G和5G技术的基础。 课程内容涵盖： * **语音信号的数字化过程：** 从声波到电信号，再到数字比特，最终转换为电磁波的完整流程。 * **2G 接入技术：** 详细介绍 TDMA（时分多址）与 FDMA（频分多址）的结合应用。 * **2G 网络架构：** 讲解基站系统（BSS）和基站控制器（BSC）的作用，以及核心网（Core Network）的组成和各节点的职能。 * **2G 信道：** 阐述逻辑信道和物理信道，以及它们在空中接口的传输方式和资源分配。 * **2G 通话流程（Call Scenario）：** 详细介绍从通话发起直到成功建立过程中，移动台与基站系统之间传递的关键信令。 * **2G 切换流程（HO Scenario）：** 解释移动台、基站系统和基站控制器在实现无缝切换过程中所交换的信令。 本课程将提供大量实用信息，是理解移动通信发展历程和底层原理的必修课程。
Hello I am Emad Salem telecommunication engineer in Egypt about 13 years experience worked for Huawei , NOKIA , Ericsson worked in Egypt and KSA telecommunication instructor for 10 years in this course we will learn together all about 2nd generation radio signal between site and mobile station , it is mandatory to follow it with 3G Basics course , 4G Basics Course and 5G Basics Course.in this course we will learn how voice signal is converted from sound wave to electrical signal then to digital bits then to electromagnetic wave.then we will learn about 2G Access Technique TDMA over FDMA and after this we will learn about 2nd generation network architecture we will know what is role of base station system and base station controller what is core network and briefly what the role of every node in itthen we will learn about 2G Cannels , logical channels , physical channels and how ti transfer in air interface and in which resources then we will know everything about Call scenario or 2G Call flow ,which messages are transferred between site and mobile station until call startsthen we will learn about 2G HO Scenario and all messages between Mobile station , base station system and base station controller until hand over is donemore and more information will be offered in this course
