Hello, everyone. I hope you are fine and welcome to the
new video.
So this is our video number 1.3 in this video. We're going
to talk about communication Technologies, of
course physical layer.
So let's get started with that.
So we have a lot of communication Technologies
such as Bluetooth its new
variant is ble and the other is a zigbee
which is specific to iot and the
next one is NFC near field communication. You
can say that it's an modified and
the advanced form of rfit and the
next is Wi-Fi, which is already in Jews and
we are using in our home and offices as well as in industry
for internet usage and
The next one is gsm2g3g LTE that
we guys are using for our mobile devices
connectivity and the next is vibro, which
is actually Wireless Broadband.
It's actually developed by
the South Korean Telecom industry. And the
other one is a y Max and the next one is the ethernet and
the second last is the Laura van and the sigfox.
These are the communication Technologies mean
available in the form of
physical Hardware.
Now we need to talk about specific communication
Technologies, which
are related to the iot. Then we have a ble
and the next one is a zigbee Lauren
sigfox and B iot. So
let's talk about why we need
to create iot specific communication
Technologies when we have already lot
of communication Technologies actually in
iot devices. Mostly there is a
issue with the power. So we need
those protocol which are power efficient
use less power so our
battery
Life will be increased and the number two thing
is that we need.
That type of protocol where we don't have a
overhead. That's why NB iot is
a specific protocol in our GSM technology,
which is which only deals with the iot devices
and that's why we created
these
communication Technologies to cater down
the iot specific requirements. So these
are the iot specific protocols.
In the next video. We're going to talk about the communication protocols
for the application layer. So
guys see you in the next video. Have a good day. Bye.
