Welcome back guys.
As the last video of Wi-Fi section, which is
video number 4.6 and we're going to talk about pros and
cons of Wi-Fi. So let's get started with that.
So firstly we will discuss advantages of Wi-Fi. The
one bigger Advantage is
good for limited area communication and it
is also good for large data Transmissions, like sending a
bigger size files from one machine to another
machine or from Mobile to another device or
you can say that machine to machine communication or it
also provide centralized connectivity to different
devices just like we have a centralized printer and an organization
and the third benefit is it is good for
real-time communication because it's for sports stack TCP
and the g80p and the fourth and the
biggest Advantage is it is using free ISM bands,
so we didn't need to pay any sort of Licensing fee
and the gateways are available and reasonable pricing
just like we can purchase a small Gateway from
ten dollar to onward depending
on your requirement and the users.
So now it's time to talk about disadvantages of
Wi-Fi. The number one disadvantage is
same like Bluetooth. We have a limited range, but the
Wi-Fi range is good as compared to the ble and
the number two disadvantages battery consumption
if we specifically compare
WiFi and the Bluetooth and Wi-Fi
consume a lot of battery as compared to the ble and
the number third part is a security issue same like
the ble If energy direct
came into your network and it starts man in
Middle attack, then it will poison the
Gateway and we'll listen all of your traffic and
it can misuse according
to his
requirements and the number four disadvantages set
up and the configuration issues because if we
buy our router firstly we
need to set up router with the
security keys with time zone and how
it works with the when
And later on we also need to put some configurations
like Wi-Fi SSID and the password on
our user computer. So it is a little bit complex as
compared to the Bluetooth. So these are the disadvantages of
Wi-Fi.
So guys in the next section. We are going to talk about
gsm3g4g as well
as Global iot SIM cards, and this
is my favorite section, and it's going
to be very interesting. So guys see you in our next section. Have a good day.
Bye.
