-: In this section of the course,
we're going to cover the concepts
surrounding wireless networks.
Now, as you're watching this video,
chances are you're already using a wireless network
to do it.
That wireless network could be Wi-Fi,
or, if you're on your smartphone,
you may be watching it over your cellular connection,
but both of these
are technically considered wireless networks
that you're using to watch this video,
so in this section of the course,
we're going to dive deep
into the different types of wireless networks
and their different uses.
Our focus in this section of the course
is going to be on domain two, networking,
and as we go through this section,
we're going to be covering objective 2.3.
Objective 2.3 states that you must be able
to compare and contrast protocols for wireless networking,
and we're going to cover this entire objective fully
in this section of the course.
Now, as we begin this section,
we're going to first take a look
at the different wireless frequencies
that are used in Wi-Fi networks,
including 2.4 gigahertz and 5 gigahertz.
Next, we're going to move into the different wireless standards
that you're going to encounter when working with Wi-Fi,
including 802.11a, b, g,
n, ac, and ax.
Then we're going to move into
the different types of wireless security standards
that you may come across,
including WEP, WPA, WPA2, MAC filtering,
and disabling of your SSID broadcasts.
After that, we're going to move into our coverage
of fixed wireless options.
This includes things like cellular, microwave,
and satellite connections.
Then we're going to move into different types
of short-range wireless communication protocols,
things like NFC, or near-field communication,
RFID, or radio frequency identification,
IR, or infrared, MBT, which is Bluetooth.
Finally, we're going to move into a short demonstration
where you're going to learn how to configure a small office,
home office wireless network,
so let's get started
with our exploration of wireless networks
in this section of the course.
