Enterprise Wireless Concepts & Implementation

因此，您对Wi-Fi有所了解。您知道什么是SSID。您熟悉术语接入点，控制器和802.11n。如果您想将自己的知识提高到一个新的水平，那么本课程适合您。在本课程中，您将学习如何操纵电磁能产生射频的基本知识。您将了解Wi-Fi调制和编码的详细信息以及“码片序列”是什么。我们将讨论RF功率以及如何使用分贝，dbi，dBm和“ 10s和3s规则”来测量它。然后，您将了解802.11n，ac和ax在过去几年中以指数方式提高Wi-Fi吞吐量的某些方式。我们将继续介绍轻量级接入点，它们如何发现其WLAN控制器以及如何实现控制器故障转移。您还将了解组成天线的组件，不同类型的天线以及如何使用极坐标图测量其增益（或损耗）。我们将教您有关WLAN漫游，Web身份验证，带有EAP的802.1x等更多信息！

So you know a little about Wi-Fi. You know what an SSID is. You’re familiar with the terms access point, controller and 802.11n. If you want to take your knowledge to the next level, this course is for you. In this course, you’ll learn the nuts-and-bolts of how electromagnetic energy is manipulated to create radiofrequency. You’ll learn details of Wi-Fi modulation and encoding and what a “chipping sequence” is. We will discuss RF power and how it can be measured using Decibels, dBi, dBm and the “rule of 10s and 3s”. You’ll then be exposed to some of the ways that 802.11n, ac, and ax have increased Wi-Fi throughput exponentially in the past several years. We’ll move on to lightweight access points, how they discover their WLAN controllers and how controller failover is achieved. You’ll also learn about the components that make up antennas, different types of antennas and how to measure their gain (or loss) using Polar Plots. We’ll teach you about WLAN Roaming, Web authentication, 802.1x with EAP…and a whole lot more!
