Welcome to the wireless section.
00:03
Let's start by exploring the benefits of a wireless network over a wired network.
00:09
The benefit of a wired network is mobility, flexibility,
00:14
scalability.
00:16
It's the wireless networks enables that you can bring your own device,
00:20
the wireless network. Sometimes it's more cost effective than the wired one.
00:27
When we say mobility, it is the biggest attraction towards going toe wireless
00:31
because
00:33
in most of the times we need to be mobile inside the place
00:38
and at the same time we need to access the network we need to be online.
00:44
We have so many mobile devices nowadays, such as the laptops, mobile phones and the tablets. These devices can access the letter through the wireless
00:54
connection. While you are moving,
00:58
Mobility enables access anywhere in the quarters in the corridors in the meeting rooms. Any of these devices can access the network through
01:08
wireless connection from the corners from the corridors, from the meeting rooms and as well. You can have mobile voice over I P phones. You can have mobile sets for the voice over I P phones that can
01:23
be handled anywhere inside the building.
01:27
The flexibility is another attraction in the wireless network.
01:33
It enables the ease off, set up and change. You do not need toe fix wires inside the place. You do not need toe change the infrastructure.
01:44
I mean the civil infrastructure of the place you do not need toe big inside the wall to fix cables. You do not need wiring hassles.
01:55
You can enable the guest excess inside the place. The guest that is temporary inside the place and passing some time inside the place can be enabled through the wireless network
02:07
you can allow to work remotely. You can allow toe access any server remotely from
02:15
another place where the server room is away from
02:21
you allow for freedom of operations you can separate. The person's working in different departments in different rooms, and they can still connect to each other wirelessly and connect to the network wirelessly. It allows freedom, which is some sort off mobility and some sort off
02:40
flexibility in changing the place
02:43
in the setup of the place. In that movement, off persons using the network
02:51
wireless networks allows for scalability. You can expand the network easily. A machine can enter or leave the network easily, much more easier than the wired infrastructure. You have saved cables. You saved connecting devices such as the switches and routers.
03:08
You saved them and replace them by a wireless excess point. You saved the outlets that exists in the world.
03:16
Tow. Connect the cables to the wired infrastructure. There are no outlets here in the wireless network. It is just the access point that connects wirelessly. Tow the other devices.
03:29
You can easily add a machine toe.
03:32
The wireless network you do not need toe. Add an outlet in the wall for this extra machine or to remove an out in the wool. If this machine leaves, this machine can be handled by a person who can enter the place and added to the network so easily and can leave the place and removed from the network
03:53
with the same
03:53
easiness.
03:55
Scalability also means that you have the capability of relocation. Inside the building. You can change the functionality of any room from a meeting room, tow an office or vice versa.
04:08
You can have less planning overhead. You do not need to plan the room from the beginning till the end to be a meeting room. It can be a meeting room for some time and then an office, an ordinary office for the rest of the day, so it it does not need to be planned
04:25
to be something that is fix it.
04:29
Scalable speed off connection. The speed off connection
04:33
for this network is scaleable. It can be adapted to the variety of devices connecting can be adapted to the first mobile phone if it is smart and tow the slow mobile phone or laptop. If it is something old model,
04:48
you can connect the hard to reach areas. The areas that can be hardly
04:56
connected through with wired infrastructure can be easily Richard through the wireless network, and through
05:02
that excess point,
05:06
you can enable here the concept off. Bring your own device with you to the place.
05:12
We have a variety of devices laptops, mobile phones, tablets that can be brought to the place tow connect to the wireless network, and you have ease off nattering establishment. Inside the meeting room inside the training center inside an office inside the canteen. Just connect the wireless excess point,
05:31
tow the sealing off this room, and it is now
05:35
a separate network
05:38
and also a connected network with the wired infrastructure through one excess point that connects these devices,
05:46
tow the wired infrastructure and enables these devices to move
05:50
and
05:53
receives the wireless signals emitted from these devices. Tow their excess point and tow the world infrastructure
06:00
and so forth.
06:03
Wireless networks are cost effective. You save the coast off cables. You save the coast off
06:10
connecting devices. You save the coast of outlets. You save the post off so many switches with
06:16
somehow cheaper excess points and somehow less in number X points. You save the labor costs that are involved in wiring. You save the labor costs that are involved in digging the wall and spreading the wild infrastructure inside the walls. Off the building.
06:35
You save some civil work that is needed toe. Allow for the cables to pass inside the building toe. Cut the walls and the floors and the ceilings toe allow or toe. Establish a path for the cables toe pass through inside the building. You save all of this,
06:55
and you saved the post off course
06:56
off the devices. The end devices as well, since
07:00
your guests or your trainees or your conference at in these can bring their own devices, their own mobile devices into your premises, connect to your network and then take their devices back so you do not have to buy them any devices and to offer them any devices on your own.
07:23
If we have a very small comparison between the word and the wireless infrastructure, we can say that wireless has many advantages, but it is not a perfect solution. We must mix both technologies in the network wired and wireless. The excess point
07:40
just connects the wireless devices. So the wire, the infrastructure,
07:44
you must have a word core network and a wireless access nutter connecting the
07:50
communicating devices. So the wired core infrastructure, a world infrastructure must exist at most of the cases toe be the infrastructure of the place, and Toby routed and toe be connected to the Internet. And then it can end with
08:09
wireless terminals that can be mobile
08:11
and can be moving inside the place. Wireless has advantages
08:18
in offering a healthy environment inside the place. It avoids the electromagnetic interference. It avoids being shocked by the electrical signals traveling inside a wire. It saves all of this and offers somehow a healthier environment inside the place.
08:35
It offers a safe premises for working because no
08:41
falling over cables inside the place will
08:45
take place or will occur, and you will have less cables mixing with water
08:52
in the cleaning process. In the water flooding process, you will have less dangerous
09:00
situation, since cables are less so. If there
09:03
there is water existing inside the place, you will find that less cables are susceptible to mix with them and less people are falling over the cables existing in the place.
09:18
Thank you.
