>> Let's just add a little bit
00:00
to our previous material where we talked about
00:00
cellular and I just want to focus in a little bit
00:00
on 5G as opposed to 4G.
00:00
When we talk about 5G, 5th generation,
00:00
what this stands for is that
00:00
basically we're going to see an increase in speed.
00:00
Speed is all the rage.
00:00
We want faster, quicker has got to happen now.
00:00
5G gives us a considerable improvement in speed over 4G.
00:00
Along with that, just the speeds at which data travels,
00:00
we also have a much lower latency.
00:00
Another benefit is that 5G uses less power.
00:00
These devices have a low-energy mode,
00:00
so we can get an extended battery life.
00:00
That's always a big benefit when
00:00
you're looking at portable devices.
00:00
We get a higher reliability,
00:00
we can have more uptime.
00:00
When we have speed,
00:00
when we have reduced power,
00:00
that just naturally translates to more uptime.
00:00
5G networks can host more devices.
00:00
We're talking about a great deal of scalability here.
00:00
Now, when we said earlier
00:00
that speed was improved with 5G,
00:00
we're looking at getting speeds of about a gigabit
00:00
per second for stationary users.
00:00
I'm just thinking going back to
00:00
the first smartphone I ever had,
00:00
which really wasn't that smarter phone.
00:00
Back in the early 2000s,
00:00
to dream of speeds of one
00:00
gigabit-per-second on a smartphone,
00:00
that's pretty good speed.
00:00
It's a significant boost from 4G,
00:00
but certainly from the others.
00:00
Also improve capability with mobile users.
00:00
And when we're looking
00:00
at like people not just roaming by foot,
00:00
but high capability of good speeds up to
00:00
100 megabits per second in vehicles.
00:00
For folks that are accessing Wi-Fi,
00:00
the potential here is really tremendous.
00:00
If you're thinking about like ambulance services,
00:00
being able to have cellular connection,
00:00
Internet and voice while
00:00
they're navigating through a city.
00:00
Fire departments, you know,
00:00
a lot of infrastructure type services can
00:00
really benefit from
00:00
an increased speed while being mobile.
00:00
Also significant.
00:00
Higher reliability with the infrastructure services
00:00
because of the redundancy that's built in.
00:00
All these are pretty significant boost over 4G,
00:00
and I think could show up on the net plus exam.
00:00
I don't know that.
00:00
You'll see a lot of questions.
00:00
I think he might see one.
00:00
I would focus on are other speed improvements.
00:00
Like I said, if we're getting one gigabits-per-second.
00:00
Those are theoretical speed of 10 gigabits-per-second.
00:00
Even they will not seeing that there,
00:00
we have that growth potential, low latency,
00:00
more devices to be supported,
00:00
benefiting infrastructure, health,
00:00
and, medical services.
00:00
That would be what I would focus on when it comes
00:00
to thinking about 5G for the exam.
