you've probably already guessed today we're talking about 5g hello you're
being a super week in public do you want to be in it right great so
before we can really talk about 5g we need to know why it's a big deal we all
know that 4G is big in America and you even have the LTE but in Europe most
places we'd kind of struggle just getting the 4G so it will take some year
but like expired and tech world both say there will be a roll out in 2020 so
that's in two years that's pretty damn soon the big deal about this is that it
would make the internet speed ten times faster so there would be no more
buffering there'll be nothing but you would be blinking it looks like we're
walking over a red light right now i strata guarded screen it screen it is
look we just walked into got into traffic so there will be no buffering
and that's amazing but the biggest difference between 4G LTE and 5g is that
5g uses high frequency waves where 4G and LTE and everything else really uses
low frequency waves but we've run out of space on those waves that's why it's
really difficult for IOT devices right now to get online Internet of Things is
IOT and it's basically when you put an internal SIM card into an object so that
it can communicate with your device and you can sort of interact with it even
though you're not near by it so freeing up more real estate by using higher
frequency waves is a brilliant thing to do but it's a lot tougher than it sounds
Nokia and Ericsson are sort of predicting 2025 but no matter when it
really happens let's just talk about the downsides because there's five
technologies that has come out because of the down sides and now made it
possible to make an even more efficient network even though high frequency waves
have some really big downsides so higher frequency waves get blocked by walls and
absorbed by rain which makes it harder to use yes and this is what we call
millimeter waves it's basically waves between 30 and 300 gigahertz it creates
a big obstacle that it can't go two obstacles so in order to sell this
we need to use mini cells which is like a small cell phone tower
we could put multiple locations throughout a city and then those waves
would be able to go through some of the walls and thereby give us Internet also
when we were inside and they would be able to give us Internet outside even
when it rains but there's more this doesn't really solve the entire issue
using these mini cells create more outputs this is called MIMO multiple
input multiple output points and it'll create much more problems because the
signals themselves are being sent out in circular waves and when we send them out
like that they can interfere with each other so we need to solve the
interference problem we definitely don't have a script for this no keep informing
which is basically a traffic signal for
it's true it is yeah it basically transforms the wave into a beam and then
we can send the signal we need to send to a specific device only to that device
meaning we cut out like 99% of the entire wave and it's only being sent out
in like a small bit to that specific device which solves part of the
interference problem then we have the full duplex technology which basically
means that you can send one signal from each side at the same time at the same
time and they won't interfere with each other exactly we kind of solved the best
prosecuted problem by creating this transistor so that instead of having a
one-way line at each time we can actually send them past each other at
the same time which is brilliant and it solves the remaining of the interference
problem this is all the five psychologies that we need to make 5g
happen we do already have them but we don't have however is an agreement on
what range we're gonna send the signals are and how much we actually need
because we need to set up all of these new towers and we need new chips and we
need new antennas in all of our smartphones before we can even take
advantage of all of this I think a great intellectual vlogging so this is a big
deal for a few reasons groups special mobile association have
come out with some numbers they're basically
saying we'll have one to ten gigabytes per second we'll have ten times the
bandwidth per unit area and we'll have a 90% reduction in the energy usage
meaning the battery problems we already have in our mobile phones might also be
solved by doing this there's some really really big upsides to it and it's really
interesting because it allows for the IOT I mentioned in the beginning
Internet of Things can all of a sudden start using this extra bandwidth to
actually get online we solve the entire real estate problem and we can start
living the high-tech lives we all wish we could live I mean I don't know about
you but I always wished I could turn on my car where I love us at work just
don't write a press of a button that's a lot of really useless functions but it
also allows for some really really really great and amazing technologies
like these let's really think about the potential for a world filled with
devices that can detect changing conditions and reacts so quickly it
makes the blink of an eye look like an eternity 360 degree VR
video + - 360 degree VR experiences back there all of them are streaming down one
single 5g connection we're actually sending 1.6 gigabits per second and
that's just the demos for using that is not the max bandwidth it's just that we
don't even have enough demos here to max out the bed width of our connection it
has two players who are meeting in personal space in the cloud and yet
they're seeing it here and in the lag is so low there's so little latency that it
seems real-time we are investing than the whole infrastructure in the cloud
the clients the network so that 5g can roll out we have already announced our
first range of commercial 5g modems the X mm 8000 series you're driving down the
street on your way to work your car is communicating with sensors embedded in
the environment your car is also in constant communication
with the city's traffic system funneling you through the best route clearing your
path of red lights and other delays compared to tomorrow our did is nothing
tomorrow IOT Internet of Things everything connected we think it were a
big data company today that was compared to yesterday compared to tomorrow we are
nothing improve people's life improve the
machines to make me sure the machine can do better job to support human beings we
don't know how data really can make money today but we know we have to
protect the privacy of the data and when we know one day the data will empower
the human being
a simple illustration is the capability for your voice to issue a command
through an interface to perform everyday tasks like turning on a light bulb or
managing your home or office security system we all need to become
technologists and product designers we've been connecting our environment to
the Internet the Internet's been around but I think the reason why it's becoming
so exciting now is that smartphones have basically commoditized this wonderful
technology that now is so cheap we can take a little mini smartphone stack and
embed it in all sorts of things in our houses in our cars on our bodies in
order to sort of have the Internet of Things
I think these interesting it as it is it not only needs this smart technology on
the sort of processing and networking side but you also need a lot of sensor
technology I've been fortunate to have worked with a couple of I think some of
the more exciting early successes in the Internet of Things nest you know it's a
really incredible team who built the Apple iPhone and you know the smart
thing they did is they they said that learning technologies allows them to
sort of predict and react and understand consumer preferences that then makes the
device really work for the customer in the future chip will cost a penny so the
internet will be everywhere including our contact lens when we blink we will
access all human knowledge that is gonna be it for this video guys thank you so
very much for watching I do put a lot of work into these so if you knew the
channel then please subscribe and let me know what you think in the comments down
below there are a lot of other possibilities with this new technology
and yeah do you have anything to add
well you do have a point you could put artificial intelligence
online a lot easier with this and you could put autonomous vehicles on the
road a lot easier because of the low latency they could talk to each other
almost in real time not too far out into the future but yeah let me know what you
guys think in the comments down below I'll see you guys next week what do you
do this like this is this is a good arm workout do you want me to hold it again
