Now, before moving ahead with the contention methods, you first need to understand what a wireless
range extender is, what can you guess?
I'll give you five seconds to answer or think.
Think from the name.
What is a wireless range extender?
Yeah.
So if we guessed that this device is used to extend the range of the device, then you're probably right.
In some cases you need the villain to extend further than the technology in use is designed to deliver.
In that case, we can deploy what is called a range extender.
Now these are radios and antennas that operate in the same frequency or channel and receive the signal
as a station word and then transmit it in the direction you desire your clients that are out of the
reach of the original access point.
For example, as you can see on the screen here, just it.
Yeah.
So you can see in the square this this person is here is use is using an Internet network, but this
guy wants to use the network.
But the range of this access point is only still here.
It does not extend for that.
The range is here blocking here.
So what to do now?
They have installed a wireless range extender here.
You can see I've marked it with green color.
Yes.
So now what this wireless range extender does is captures this frequency and then it's in all the parameter
available.
So now this person here can access the Wi-Fi or the Internet of this room.
So in short, wireless range extenders are basically used to extend the range of the original access
point so that the anyone who's out of range of the original access point can access the Internet without
any issues.
This is all for a range extender in the next lecture.
We'll see what is meant by a convention method and how introduction to to mean convention methods that
you must understand in computer networking.
