Hello, you Pirates of the Cloudy Caribbean. Welcome back to Cloud Architecture, foundations and this modules about cloud manage data to 11 wireless 802.11 Wireless networking over radio has been around for a long time, but now one of the primary ways wireless land architecture is being rolled out into the enterprise
is by way of connecting and managing
on premise based attitude. 11 radios and wireless access points to the cloud,
so a total of 11 is part of the IEEE 802 sets of local area networking protocol issues for the implementation of wireless local area network. W land WiFi computer communications. So you younger folks don't have an appreciation of the fact that wireless networking is only 20 years old, and before that time
there is no such thing as the Internet on your phone or on your laptop
while you move around the office or moved around your home is pretty interesting. How wireless networking was a luxury in early networks, and now is it is expected. Everywhere we go, we don't have just the expectation of wireless networking while we're waiting for the bus, the train or that plane, but we expect wireless networking service while we're on them.
When you think about the fact that early wireless on Lee worked indoors for about 100 feet from the radio
to now, where you can get on wireless networks and use the Internet while you are flying on a plane at 30,000 feet in the air while traveling of 500 miles per hour really boggles the mind? This slide shows how, over the years, the attitude 11 standards have evolved to provide faster wireless networking speeds
from its inception of 11 megabits per second with the $802.11 be standard
to today's 802.11 a x standard of an amazing 10 gigabits per second. What has not shown as a term called client density or the number of simultaneously authenticated users connected to a wireless radio that has gone from just a handful of users per radio at early inception of standards to today,
several 100 simultaneously authenticating clients
per wireless access point. Pretty amazing stuff,
So I really like this graphic because it represents in the looking glass the portion of the radio spectrum that you and I get to use not necessarily get to control, but we get to use our radio channels, satellite transmission, cellular communications, everything that you and I might use over radio waves. But as you can see, the full range of the radio spectrum is huge
and is all controlled by federal governments across the world,
from airplanes to emergency service is there are a ton of radio waves and forms of radio communications that you and I just ignore every day but are a fact of life in the radio world. The radio frequencies in the U. S. Air controlled by the Federal Communications Commission, the FCC and the majority of the spectrum out there is what we call licensed.
You pay a license to the FCC to use the frequency,
whether it be a yearly licence or even for 10 years or more. And then when you get to Europe and Japan and China, these countries and regions have their own radio spectrum management agencies and their own licensing agreements, for example, the radio channels were authorized to use in the USA are different in Europe, Japan or China.
Here in the states, the FCC has released what they call
unlicensed frequencies or radio frequencies in radio channels that anyone can use without any form of license, and this free to use portion of the radio air spaces where we take our magic carpet ride on the attitude of 11 wireless network.
So there are a lot of types of wireless networks over these free, unlicensed radio channels that are used to broadcast 80 2011 wireless radio for limited areas such as home school's computer laboratories, campuses and office buildings. We can walk around within the radio coverage area and still be connected to the network via a wireless gateway
that most often now is connected to the Internet
and is our wireless pathway through the Super Information Highway. An independent basic service set is an ad hoc network that contains no wireless access points, which means that they cannot connect to any other wireless basic service. Set a basic service center be SS has a set of computer stations that connect with each other using a wireless access point
on the devices
are in the same basic service, set all components that could connect into a wireless medium in a network or referred to a stations where each of these stations have a wireless network, interface controller or a wireless nick. There are two categories of wireless stations. Wireless clients and wireless access points. Wireless access points are raps.
Our wireless bay stations that actus wireless routers that transmit and receive radio frequencies
for wireless enabled devices to communicate with
early wireless networks were very simple and design a lot like everybody's house these days, where a single wireless access point and a single wireless radio connects all of our wireless devices and allows them to talk because they're in the same layer to network, these devices communicate by exchanging layer to Mac lir frames on the same radio channel E
same radio frequency.
Early wireless lands would use channels one through 11 on a 2.4 gigahertz frequency spectrum and 802 to 11 be network and up to 11 megabits per second.
Back when I was in school, everybody wanted to be popular and cool like the Fonz Arthur Franz, really a Who was the cool drop out in the high school television series Happy Days. So like Fonzie, the wireless network was very popular, and as its popularity grew, the wireless network and its capabilities needed to grow and scale to keep up with demand.
So the next step in wireless architecture was having in your radio to 11 wireless network multiple access points
and as you moved around the office, your wireless client in your laptop with Rome and would drop its connection to one radio and re associate and re offended Kate to the nearest radio in range. Our wireless never grew in scale and size to support our growing network.
The wireless network got really big, really fast, and assets became very difficult to manage. Each wireless radios its own management point. If you have a wireless network with 100 wireless radios, you have 100 separate management points. You have to give each radio its own management. I p address. You have to configure your wireless networks, your corporate wireless network, Access I D
Service said. Identify air and your guest S s I. D.
He has to configure which radio channels Your wireless access point is to use all of these things over and over on all 100 of your access points. And if you make a change or need to add a new wireless network, access i d you have to manage the 100 access points all over again. So the industry created this really cool architecture called a wireless controller where your access points
are no longer managed independently. They're all managed by this management appliance called a wireless line controller or W L C.
Now all my management, traffic control, traffic and even my wireless client data traffic All this separately tunneled over the network to our controller. If I need to create a new S S i d a new wireless network, I create it once on my wireless land controller, and it pushes out the new s s i d to each of my wireless access points
one point of management rather than 100 points of management.
So today's first choice for many enterprises that not to deploy on the premise Wireless land controllers, for their own premise wireless access points but rather let the cloud manage their wireless access points, their production and guest networks, their guest user complaints and acceptable use blast pages
by tunnelling all their wireless management traffic to the cloud. Almost every network manufacturer from Cisco Muraki to ruckus watch guard lynxes Aargh hive.
Just dozens of cloud wireless players in the space, all offering the benefits to the network of not having to manage your own wireless lan controllers your own infrastructure to control and manage your wireless network rather by their access points. Plug them into the network. They automatically tunnel to their cloud controller. And then when you open up your cloud dashboard,
there are all your wireless access points registered to the controller
and ready to be giving your marching orders really simple and really, really cool stuff.
The management of your wireless network is so easy when used the cloud with each of your access points, you pay a yearly subscription for the access point to talk to the cloud. A cloud license. This license gives you access to not only really simple management of your wireless network, but incredible business intelligence or B I, which is incredibly expensive and complex to bring on premise.
Another really slick feature of wireless cloud management
is the sheer scale of its capacity and the sheer simplicity of your management of that capacity. The cloud doesn't care if you're access points or just in one office or across the globe. Everything comes into your single cloud dashboard. The single point of glass management approach to promise based wireless systems for global corporations is nearly impossible to pull off
without using a service
like the cloud.
The benefits of cloud based wireless management are many, including never having to back up the configuration of your wireless access points and ever having to patch their software. The cloud does this stuff for you. The network is simple to manage from any browser and for many, device deployment of wireless access point to a cloud. Management is incredibly easy. Just plug in your access point,
it tunnels to the cloud and then click open a browser and start to manage your new wireless radio.
That's it. But there are some considerations for you. An I T that you need to consider the cloud is only as reliable as your connective ity to it. Make sure you have encryption and other security practices in place, and watch those firewall changes that you don't open too many ports and leave yourself vulnerable to threat agents from outside your network.
Cloud wireless, if done right, can be incredibly simple,
can deliver incredible features and performance and can be deployed very securely.
Oh, no, mate EADS. It's time for that. Scary Pirates of the Caribbean Learning Check
What are two types of radio frequencies controlled by the FCC in the United States?
What are three ways to manage a wireless network?
What steps to registering a cloud managed access point to the cloud management controller?
And what are three advantages of cloudy? Goto 30.11 wireless. Now go put on your eye patch and sharpen your sword. And when you are ready to swash your buckles, come on back to the Black Pearl pirate ship and we will review our answers together. Maybe
rum drinks, rum drinks. Nobody gets rum drinks until we get our questions. Right are two of the two types of radio frequencies in the radio spectrum in the states that are managed by the FCC are licensed and unlicensed radio frequencies, the unlicensed rul frequencies of the 2.4 gigahertz
and five gigahertz bands we care about for 802 down 11 Wireless.
The three ways we can manage a wireless network are on each independent wireless access point or by tunnelling our traffic to a wireless line controller and managing our radios on that controller or by tunnelling our radios to the cloud controller. The steps to registering our cloud managed access point couldn't be easier. We plug it in
your network gives the access point an i p. Address the access point tunnels automatically over the Internet to the cloud controller and a Holy maids land ho. We see our access point in our wireless cloud controller dashboard,
and there are so many advantages to cloud managed wireless. But the three advantages we mentioned were simple configuration backups and simple patching of the software under radios. Both service is handled by the cloud controller for you. Incredibly simple demand is cloud wireless
and finally, amazing cloud business intelligence. Providing your visibility and intelligence tow how your organization uses a toe to toe 11 wireless land technologies. Today we learned about the 80 to the 11 Wireless, and it's hugely popular success, and we learned about the three ways we can manage a wireless network, including Cloud Managed Wireless,
and we talked about the benefits of cloud managed wireless, including how the clouds simplifies, how We Manage Wireless Networks Day Today and The Incredible Business Intelligence about our wireless trains using Cloud B I. Next time we start module six, we will learn about virtual ization because it is virtual ization that makes this whole thing we call the cloud possible.
So cloudy. Cheers, Maybes.
And on behalf of all of us that the cyber and security I t Learning team we wanna wish you and all of the users on your network Good day. Thanks for joining us and happy packets.
