 Hello and welcome to this course titled
 an overview of Wi-Fi components

0:00:12.080000 --> 0:00:14.440000
 and architectures.

0:00:14.440000 --> 0:00:19.060000
 My name is Keith Bogart and I will
 be your instructor for this course.

0:00:19.060000 --> 0:00:22.300000
 Should you have any questions or doubts
 as you're going through this course,

0:00:22.300000 --> 0:00:23.580000
 feel free to reach out to me.

0:00:23.580000 --> 0:00:27.340000
 I've given you here my direct email
 address, a way to connect with me

0:00:27.340000 --> 0:00:30.260000
 via Twitter and via LinkedIn.

0:00:30.260000 --> 0:00:33.820000
 So let's just talk real quickly about
 the course prerequisites that I

0:00:33.820000 --> 0:00:35.420000
 will expect you to know for this.

0:00:35.420000 --> 0:00:37.460000
 In short, there's not a lot.

0:00:37.460000 --> 0:00:43.180000
 This course requires basically really
 no understanding of Wi-Fi beyond

0:00:43.180000 --> 0:00:47.720000
 knowing that it's used to transmit
 data wirelessly through the air.

0:00:47.720000 --> 0:00:51.720000
 You should know what an access point
 is so that term should be familiar

0:00:51.720000 --> 0:00:55.260000
 to you. And beyond that,
 there's not much else.

0:00:55.260000 --> 0:00:58.760000
 So, really, I just need you to have
 a high-level understanding of the

0:00:58.760000 --> 0:01:01.520000
 roles of common Wi-Fi components.

0:01:01.520000 --> 0:01:05.140000
 So what are you going to learn in this
 course, in this series of videos?

0:01:05.140000 --> 0:01:06.920000
 Well, you're going to
 learn a lot of stuff.

0:01:06.920000 --> 0:01:08.340000
 I've got several objectives here.

0:01:08.340000 --> 0:01:11.480000
 Number one, I want to help you to become
 familiar with the various wireless

0:01:11.480000 --> 0:01:13.840000
 LAN architectures available.

0:01:13.840000 --> 0:01:17.100000
 You're going to learn about things called
 like converged versus distributed

0:01:17.100000 --> 0:01:21.360000
 versus flex connect, all sorts of different
 ways that you can implement

0:01:21.360000 --> 0:01:23.300000
 a controller in your
 wireless network.

0:01:23.300000 --> 0:01:26.380000
 So that takes us to our second objective
 here to allow you to differentiate

0:01:26.380000 --> 0:01:31.780000
 between the different types and placements
 of wireless LAN controllers.

0:01:31.780000 --> 0:01:34.120000
 But we're not going to forget
 about the little access point.

0:01:34.120000 --> 0:01:36.880000
 It plays a critical role
 in your wireless LAN.

0:01:36.880000 --> 0:01:41.000000
 So we also need to know what the different
 modes are than access point

0:01:41.000000 --> 0:01:44.700000
 can be in. There are several different
 modes which determines its operational

0:01:44.700000 --> 0:01:48.080000
 characteristics and a whole
 variety of other things.

0:01:48.080000 --> 0:01:51.620000
 So you're going to learn all that and
 a whole lot more in this course.

0:01:51.620000 --> 0:01:55.380000
 So thank you for joining me and I look
 forward to having you in the next
