5G: Explained

5G: Explained

 

hey what’s up guys I’m could be

here so I got kind of curious with

seeing all these videos in my sub box

for the past couple months of people

getting taken to Chicago to test 5g and

doing all these crazy speed tests but

then I started to notice they all sort

of have a couple things in common but

really it was just getting me curious

about the whole thing

so I bought a 5g phone and then I drove

to the nearest 5g city and I tried it

for myself

so this is my new $1600 Samsung Galaxy S

10 5g on Verizon and so the crew and I

drove from the studio to the nearest 5g

city which is Providence Rhode Island so

for those unfamiliar a brief explainer

what is 5g well we all have 4G now 5g is

the fifth generation of wireless network

technology and so all the big carriers

are working on building out their 5g

networks right now Verizon AT&T Sprint

we’re all working on 5g the main theme

of 5g is again speed every new

generation of the wireless networks are

significantly faster and more capable

than the previous some of you may

remember the old and very slow to G and

3G and how much better 4G is than those

5g represents another step forward so to

take advantage of 5g you need a 5g

device with 5g radios and a 5g network

so for me that’s the galaxy s 10 5g and

it’s Verizon who’s building up their 5g

network in certain cities one location

at a time so you can’t just get a

software update to a 4G phone to just

enable 5g that’s right I’m talking to

you AT&T changing people’s status bars

to say 5ge

when it’s really just 4G it’s stupid

it’s basically a lie you’re kind of

trying to trick people into thinking

they got 5g v ge is not 5g it’s still 4G

it’s really shame anyway 5g is built on

what’s called millimeter waves it’s a

new section of very high frequency

spectrum upwards of 20 gigahertz all the

way to near 96 gigahertz but the

is the higher the frequency of any wave

the lesser the range like that’s just

the truth on paper so for the same

reason five gigahertz Wi-Fi doesn’t

travel as far as 2.4 gigahertz Wi-Fi the

same reason microwaves don’t cook things

on the other side of the glass wall

that’s the same reason 5g doesn’t travel

as well through the real world so

millimeter waves biggest problem is that

even if you’re standing pretty close to

the node like a couple hundred feet away

it only really travels well within

direct line-of-sight so things like

trees and walls and buildings block and

disrupt the high frequency signal even

if you’re still close to it I’ve heard

even that rain in the air could

potentially be a problem so this is why

I wanted to test this for myself so we

drove to Providence Rhode Island which

is on the growing list of horizons 5g

cities it’s not the whole city that’s

one big 5g hotbed it’s only certain

areas sort of tucked away happens to be

near Brown University where we found one

of them and we found it by finding one

of these this is a 5g node or three

nodes to be specific at the top of a

light pole you could tell because it

said Verizon right on the pole and

because if you stand right next to it

with a 5g phone in your hand and run a

speed test the results are just

absolutely ridiculous the 4G and the

notification bar switches to indicate 5g

and you open up your app of choice and

run a speed test and I’m seeing easy

seven hundred eight hundred nine hundred

often well above a thousand megabits per

second download highest result I

actually saw in my personal testing was

1.9 gigabits per second briefly from

fast comm that’s just that’s that’s just

hilariously fast like you could almost

use your whole data cap in a minute

dreamlike speeds very very nice of

course you want to see what this type of

speed is actually good for other than a

speed test so YouTube videos just played

instantly without any buffering in HD

I could fast-forward right off the bat

no problem what browsing of course would

be super fast hopping into the Play

Store to download a gigantic game like

pub G mobile progress moves pretty fast

not like a blink of an eye and it’s done

but

miles better than it would be on LTE the

fortnight downloader progressed faster

than the fortnight installer would have

meaning it’s it’s crazy impressive and

downloading an entire stranger things

episode from Netflix in HD on this phone

took about four seconds so you could

grab a whole season in probably like 30

seconds if you wanted to which is again

absolutely ideal but again here’s the

thing this is all while standing like

right next to the tower with a direct

line-of-sight you know perfectly ideal

conditions great weather once I left

that it kind of broke down pretty

quickly so right around the corner of

this brick building just to get into the

shade so literally maybe 75 feet away

from the node but behind a wall I’m

getting much slower 5g it’s still 5g but

you can see the numbers here now I mean

it’s kind of crazy to call 200 300 400

down slow but compared to what I was

getting before that’s a pretty big

difference to basically cut your speed

in half just by walking a couple meters

down the block and I also noticed just

by walking halfway down the block I’d

start bouncing back and forth between 4G

and 5g and like it was frustratingly

inconsistent even when I did have a line

of sight with maybe a tree or two sort

of nearby my phone would drop 5g and

then jump back on again

I think it’s seated in the notification

bar it would drop back to 5g and then

back to 4G and then when I was on 5g and

I ran the speed test it would be great I

get a thousand down again which is

Hussam but when I ran it at 4G I would

get 4G speeds and its really good for G

speeds but it was just weird getting

those results back-to-back like half a

block away and what I waited a minute

I’d suddenly get 5g again and get a

thousand down so what’s the solution for

this well as we understand it basically

just putting a lot of nodes all over the

place so essentially to maximize

coverage and improve technologies so

that when you move behind one obstacle

or sort of drive through a city you

actively switch between nodes that

you’re connected to kind of like we do

now with 4G towers but just much faster

and I think that’s the part that kind of

scares people it seems seems like a

brute-force way to actually go

fixing the problem but that’s the

current plan is just blanket areas with

these lower powered cells that let you

switch between them very very quickly

instead of one giant 4G tower like you

have now my gut feeling is that an

infrastructure where you cover an entire

city and eventually an entire country in

these little nodes is gonna be

incredibly expensive and probably take a

very long time like years so it’s a long

way off but here’s another thing to

notice even with me standing right next

to a 5g node and holding a brand-new

2019 5g phone there were still some

drawbacks to notice the main three are

heat battery and upload so for one the

upload appears to still be happening at

4G speed you want to connect it to 5g I

never broke 100 megabits per second up

in all my testing which is still a great

speed but my dream of uploading an 8k

YouTube video in like five seconds or

going live streaming high resolution VR

or something like that are not possible

at all yet now you’ve probably also

noticed the ping is still at 4G levels –

the goal is to get this down to a

millisecond or less but that isn’t

happening yet in these tests either and

then heat and battery are something that

this phone seemed to specifically suffer

from when I was testing I started my day

when we got to Providence with 75

percent battery did all my testing and

that maybe took about four or five hours

and when we finished I was at 21%

battery and the phone was warm to the

touch the whole time this is why you see

5g versions of phones coming out almost

always have a larger battery than their

normal for G brothers including the

Galaxy S 10 5 G and the phone getting

warm during the testing – when I wasn’t

even gaming or doing anything

graphically intensive just watching some

YouTube videos and download tests was a

little concerning so the bottom line 5g

is like folding phones right now in 2019

clearly not ready yet but when you use

it and you get just the right use case

and you’re at just the right space you

get this amazing little glimpse into the

future that you wish was ready for right

now because it’s so great but it’s not

and currently the cons sort of outweigh

the pros

and I wouldn’t spend extra money on it

right now in 2019 the future of 5g is

really bright assuming you know the

infrastructure happens and isn’t too

obtrusive and that’s a big assumption

but then we’re talking virtual reality

streaming and networks of autonomous

cars that are all internet connected and

talking to each other and maybe even

think about remote surgery with a 5g

connected robot in one country with a

doctor over here and a patient in

another country and everything just

working seamlessly like all this super

high-bandwidth low-latency stuff maybe

the end of video buffering altogether

all seem possible but as of right now in

2019 it just isn’t ready yet but I’m

super ready for what it is either way

thanks for watching catch you guys in

the next one peace

big thanks to Nord VPN for sponsoring
