Welcome to CCNA Wireless 200-355 WIRELESS FUNDAMENTALS Bootcamp.
In this course you will learn ccna wireless exam topics and important and useful subjects for your profession.
Lets go over each chapter and go on more detail about what to come in this course,
First off, you will learn a great deal about rf fundamentals.
This is the starting point for your wireless journey and it will lay a good foundation for the following chapters
In the first chapter we will be describing the propagation of radio waves, we will learn about rf signals and the spectrum.
We will answer some questions like: What is frequency, what is wavelength, what is amplitude and what is phase difference.
We will also learn about different phenomenas related with rf signals such as absorption, reflection, diffraction, scattering, refraction, multipath and fading.
We will also learn free space path loss and also fresnel zone.
 
On the second part of this chapter, we will go deep into rf fundamentals, what is signal strength, what does RSSI mean, how to calculate transmit power.
We will go over some different interference types and the noise, what are different device requirements and capabilities.
We will also learn principles of rf mathematics, how to calculate dB, dBi, dBd, dBm and how we can measure different power levels.
We will also learn to calculate EIRP. We will see wifi antenna characteristics, how does the radiation pattern of an antenna occur, what is polarization,
how gain is measured, what is the beamwidth of an antenna and we will go over different types of antennas: Omnidirectional, yagi,patch and dish 
We will explain different antenna connectors and why we need them and lastly, we will study amplifiers and attenuators
On our second chapter, we will learn about 802.11 Technology Fundamentals
In this chapter we will describe basic Wi-fi governance, what are the governing regulatory bodies, what is IEEE, why do we need to learn about ieee 802.11 and what is wifi-alliance.
On the second part of this chapter, we will also learn about usable channel and power combinations. We already learned about EIRP, we will also learn its limitations. We will be learning about ISM and UNII frequency bands. We will go over rrm fundamentals on the last part of this chapter
We will also learn about 802.11 fundamentals, what is modulation, what is channel width, how do we use them. We will learn about MIMO multiple input multiple output, we will go over wireless topologies and we will learn different wireless frame types such as management, control and data. So simply we will learn a lot about 802.11 fundamentals in this chapter
In Chapter 3 we will learn about various Cisco wireless architectures.
We will learn why we need autonomous, cloud architecures, why do we need split mac architecture and we will learn differences regarding centralized flex connect and converged deployment types, then we will go over physical connections for wired and wireless infrastructure. We will understand how to connect wlcs to switches how to connect different ap types to switches and why do we need etherchannel and also learn what do wcms on switches add us in terms of benefits.
Then we will examine wlc and ap management access connections, what are different management methods, what are wlc ports, what the different wlc interfaces do and we will also learn why we should disable management via wireless.
Capter four is about operating a wireless network.
In this chapter we will talk about how to execute initial setup procedures for various cisco wireless infrastructures, how to do initial setup for autonomous access points, how to setup cloud aps and manage them. We will learn how to setup centralized wlcs and wireless control modules.                                                    Next up, we will learn ap boot process and different capwap discovery methods, then we will understand what are different capwap join processes
and we will learn how access points choose to join a specific wlc. What is the master controller, why do we need primary secondary and tertiary controllers
W wil also compare different access point modes, such as monitoring mode flex connect mode and wips
O the second part of this chapter we will configure a simple wlan, what do we need to
