5g millimeter wave

let's talk about 5g the latest and 

greatest mobile network that they say is 

going to transform our lives .

It sounds promising 5g will let us 

download an HD movie in seconds. 

that's just hilariously fast, doctors 

will be able to perform remote surgery 

with virtually no lap time and it'll 

make self-driving cars smarter and safer 

but there are also suspicions that 5g 

will expose us to more security breaches

privacy issues and even health problems.

So what exactly is 5g and how much of

the excitement or fear is just

heightened. We all know 3G and 4G they're

the mobile networks we use today you see

them at the top of your phone and they

give us access to the Internet but we're

now making way for the next generation.

5g is promoted as the best and fastest

connection around and in some countries

it's already available. South Korea

launched 5g networks last year

so did providers in China the UK the US

and Germany. New 5g phones are on the way

 Samsung released the first one in

2019 bringing commercial 5g to life

before the rest so here is how it works

5g uses a wide range of radio

frequencies starting from the lower end

which we already use for television and

Wi-Fi all the way up to what's called

millimeter waves which are extremely

high frequency and used for things like

radar guns and security screening at

airports

this means that VG can carry huge

amounts of data faster and that's a big

reason why we need it our mobile

networks are running out of capacity

soon they won't be able to accommodate

the growing number of devices were using

and there's money to be made

governments will earn revenue by

granting 5g licenses the other reason to

move to 5g innovation we have more

sensors in the world

clocking data and transmitting them back

and forth in a smart intelligent hybrid

way

it is sort of like a Jetsons like

futuristic technology my ingredients and

I get recipes he's talking about what

they call the Internet of Things and

what it means is more and more of our

devices like smart speakers or exercise

equipment will remember and even

anticipate our preferences and five gene

will allow them to talk to each other at

a record speed it will be connecting

many more devices to the Internet for

the same probably amount of money and

without interfering one to each other

the challenge with 5g is coverage

shorter wavelengths carry more

information but are more easily blocked

by things like trees and walls with 4G

transmitters or base stations can be

several kilometers apart but with 5g

they need to be closer which means we

need more of them one estimate suggests

the US alone will have to install 1

million new towers that's why 5g is

really more of a gradual rollout not a

launch because all of that back-end

infrastructure will take years to build

what we're going to see as a substantive

replacement or upgrade of the course

systems that telecommunications

companies provide that's going to be a

really massive investment the problem in

some places is that big phone companies

have only just finished building their

4G networks they want to both enjoy the

benefits from the week the profits of

money they put into it but also they

recognize that well there's this

assertion that we're in a 5g race it's

not a short-term race it's a very

long-term marathon and the race is

already getting crowded some of the big

names in 5g are Ericsson from Sweden

Nokia and Finland and Samsung from South

Korea but one company is way in the lead

today as the world's biggest supplier of

networked telecommunications equipment

Huawei has been bidding for contracts

around the world to set up 5g networks

but the Chinese company isn't welcome in

a lot of places Australia New Zealand

Taiwan and Japan have all blocked Huawei

from building their 5g networks so as

the u.s. the Trump administration has

even put pressure on the UK Poland and

Germany to stop them from working with

Huawei there's an obvious business

reason for that Huawei has been crushing

the competition and the Americans want

in but the country's shutting cual way

out say there's more to it for the US

and many Western nations the tech giant

is a spying tool for the Chinese

government Chinese law requires these

firms to support and assist Beijing's

vast security apparatus allegations its

top executives deny they insisted

Huawei's not in the pocket of China's

government Huawei is basically accused

of being a pawn in China's

state-sponsored spying and there's an

assumption that you know in terms of

cyber crime and cyber war there's like a

bluff on the east that's leaving all

these attacks there's a strong

expectation at least in North America

and parts of Western Europe that

relations with China will become more

antagonist ik not you know due to a

military conflict is something of that

nature but on the basis of trade on

foreign policy on human rights and

issues like that but 5g also stirs up a

lot of debate about our own individual

privacy we're facing a future where more

and more of our basic household items

will be connected to a 5g network that's

a lot more data being collected like

what you watch on TV where your car is

and whether there's someone at home if

information advertisers are after and

it's data that others might want to

misuse and so if you are acquiring baby

monitors or you're acquiring door locks

or any of the other Internet of Things

things really looking at them carefully

to determine whether the vendor is

committed to providing a secure product

on an ongoing basis which brings us to

another concern our health with all

those extra radio waves swimming around

us people are worried

when that dimension getting the infant's

 some experts seem to think 5 G's shorter

wavelengths are actually less harmful

than the radiation from devices we're

using now it's just a little ironic to

me that people are already about 5g when

once you get to that millimeter wave

regime all your deep tissues are quite

safe it's really only your skin this

Punk you get any exposure it's the same

pattern with any new technology right

there's excitement and Wonder but also

skepticism but we're talking maybe 5 to

20 years before we really see 5g in full

effect .
