**课程名称：** 5G 网络从零到英雄 (面向英语学习者) **课程概述：** 本课程旨在全面讲解 5G 网络的理论与实践细节。5G，即第五代移动通信技术，是继 4G 之后的新一代宽带蜂窝网络技术标准，于 2019 年开始全球部署。预测到 2025 年，5G 用户将突破 17 亿。 与前代技术一样，5G 网络也是一种蜂窝网络，服务区域被划分为称为“小区”的地理区域。小区内的所有 5G 无线设备通过本地天线的无线电波连接到互联网和电话网络。5G 网络具有更高的下载速度，最终可达 20 Gbps。此外，5G 拥有更高的带宽，能够连接更多设备，有效提升拥挤区域的互联网服务质量。 凭借更高的带宽，5G 网络有望成为笔记本电脑和台式电脑的通用互联网服务提供商 (ISP)，与有线互联网等现有 ISP 竞争。同时，它还将促成物联网 (IoT) 和机器对机器 (M2M) 领域的新应用。请注意，仅支持 4G 的手机无法使用 5G 网络。 **课程内容详情：** * **第一部分：引言** * 引言 * 观看课程前的注意事项 * 为什么选择 5G？ * 5G 的用例与需求 * **第二部分：5G 网络架构** * 5G 网络阶段和双连接 * 5G 网络选项 * 网络切片 * 5G RAN (无线接入网) * 5G 核心网 * 5G 安全与 RRC 状态 **建议：** 在开始学习本课程之前，最好对 4G 网络有扎实的了解。本课程适合初学者和专家。 **附加信息：** 课程提供讲课时使用的演示文稿。 **教学大纲：** 无。
5G Network From Zero to Herowith all theoretical and practical detailsIn telecommunications, 5G is the fifth generation technology standard for broadband cellular networks, which cellular phone companies began deploying worldwide in 2019, and is the planned successor to the 4G networks which provide connectivity to most current cellphones. 5G networks are predicted to have more than 1.7 billion subscribers worldwide by 2025, according to the GSM Association.Like its predecessors, 5G networks are cellular networks, in which the service area is divided into small geographical areas called cells. All 5G wireless devices in a cell are connected to the Internet and telephone network by radio waves through a local antenna in the cell. The new networks have higher download speeds, eventually up to 20 gigabits per second (Gbit/s). In addition to 5G being faster than existing networks, 5G has higher bandwidth and can thus connect more different devices, improving the quality of Internet services in crowded areas.Due to the increased bandwidth, it is expected the networks will increasingly be used as general internet service providers (ISPs) for laptops and desktop computers, competing with existing ISPs such as cable internet, and also will make possible new applications in internet-of-things (IoT) and machine-to-machine areas. Cellphones with 4G capability alone are not able to use the 5G networks.Course contents in details is as follow:Section 1:IntroductionLecture 1:IntroductionLecture 2:Important Note Before Watching The CourseLecture 3:Why 5G?Lecture 4:5G Use cases & requirementsSection 2:5G Network ArchitectureLecture 5:5G Network Phases and Dual ConnectivityLecture 6:5G Network OptionsLecture 7:Network SlicingLecture 8:5G RANLecture 9:5G CoreLecture 10:5G Security & RRC StatesWe recommend to have a good knowledge about 4G before starting the course Course is for both beginners and expertsattached with course the presentation used in explanation
