- As five G technology begins to get implemented

there's a lot of confusion and concern over what it is,

So today we're gonna go over all aspects of five G.

who's gonna explain why people are so excited

And then we're gonna take the science angle

about how it actually works, what it does to your body

what the science says on whether or not it's safe.

- We have looked at hundreds of scientific papers

and journals in order to decipher the truth about five G

into some of the conspiracy theories and claims,

so stick around for the end of the video when we do that

But first, we're gonna throw it to our friend, MKBHD,

to tell us about what's going on with five G tech right now.

So five G technology or the fifth generation

of these data networks has been getting a lot of hype

and it's been slowly rolled out over the past year or two,

and getting insane speeds on some phones.

So the wavelengths used for five G technologies

can be split into three different sections.

which is frequencies below about one gigahertz.

Then there is what we call mid-band five G,

which is faster but travels a shorter distance.

And so with five G now we're talking about download speeds

of anywhere from 50 megabytes per second,

all the way up to those crazy millimeter wave speeds

you might have seen of like two gigabytes per second,

which is insane, I mean, that's we're talking like

a whole TV show season downloads in seconds,

and low latency in the future will be essential

for things like fleets of driverless cars

communicating with each other to never crash,

but that surgery being performed remotely in real time.

So I had the chance to use some early five G,

it was millimeter wave, and it was really impressive

but you could tell it has a long way to go

before it can be used and rolled out to the world.

and it's very easily blocked by obstacles,

So it would take a lot of nodes and a lot of antennas

and that would be expensive and time consuming.

But even the low to mid-band five G can still be impressive

but it is a pretty exciting future of five G

but with that comes a lot of fears and concerns

about the potential effects of these new frequencies

So for that, I'll throw it back to Greg and Mitch

we actually have to learn about one of my favorite things,

So yes, we will be talking today about radiation.

but it's important that we know that radiation

On the left of the spectrum we have really long wavelengths,

and as we move to the right, they get shorter and shorter

to even a fraction of the size of an atomic nucleus.

Now a wavelength size is measured from peak to peak,

Basically, the distance over which the wave shape repeats

or the size of this literal tattoo on my arm

because yes, I do love the electromagnetic spectrum.

As the wavelengths become shorter and shorter,

that pass a fixed place in a given amount of time,
