0:00 regardless of whether you're one of those diehards who's first in line at
0:03 the Apple Store it always seems to feel like no matter what kind of mobile
0:07 technology that you have in your pocket it quickly becomes yesterday's news and
0:12 that may never be more evident than right now as telecommunications
0:17 providers worldwide are working on
0:20 5G which might be just as big of a deal as when we marveled at being able to
0:25 look at full fat web pages on Tiny phone
0:28 screens oh H come on Luke another G just
0:32 after LTE became super widespread well
0:35 while it's admittedly a bit tricky to keep up with all the freaking different
0:39 Wireless standards and the G's and what they all mean and all that kind of stuff
0:43 which you can learn more about up here the industry is hoping that 5G will be
0:48 good enough to end constant talk of what the next G is good luck with that and
0:53 we'll hopefully only need incremental improvements over time kind of how
0:58 Windows 10 does that and they plan on updating forever see how that goes so
1:03 what the heck is supposed to be so special about 5G anyway well it's being
1:08 centered around the idea that the internet of things that is connected
1:12 devices that enable self-driving cars automated homes and more will become
1:17 very important in the near future and that mobile data networks will need to
1:22 be very robust to handle it all with
1:25 wearables appliances Vehicles mobile AR
1:28 and VR devices and so on one expected to push so much traffic through mobile data
1:32 networks with some devices needing as many as multiple gigabytes per second we
1:39 will need not only faster overall speeds but also lower latency imagine if your
1:44 self-driving car took half a second too
1:47 long to make a critical turn and suddenly you've got a huge dent in your
1:51 Fender or more frighteningly in your body 5G however is not only aiming to
1:58 reduce latency to as low is 1 millisecond to allow realtime operation
2:02 of important devices it also boasts a theoretical maximum speed of 20 gigabits
2:08 per second way faster than the quickest LTE networks today or even Google Fiber
2:14 connections of course this is a theoretical maximum and it looks like
2:19 the bare minimum for the average user will be about 100 megabits though again
2:24 this is still quite a bit faster than real world performance of many LTE
2:28 deployments part of this awesomeness is due to 5gs usage of higher frequency
2:33 waves which also gives it a much greater capacity for beam forming meaning
2:38 signals can be focused onto areas where there's more data traffic compared to
2:43 existing cellular antennas many of which are just omnidirectional and just kind
2:48 of send signals out without regard for where usage is actually concentrated
2:53 which is not good combine that with massive mimo which will allow many users
2:58 to share the same connection simultaneously with multiple antennas on
3:02 a transmitter similar to the newer mu
3:05 mimo networks for home Wi-Fi connections
3:08 and you'll have a network that is not only quicker but also has better
3:12 throughput so the quickly growing number of things connected to the mobile
3:17 internet don't become bottlenecked in fact the industry is hoping to have a
3:22 million devices supported per square kilometer possibly meaning no more
3:27 delays at places like concerts conventions or sporting events of course
3:32 this is a very ambitious project so it's not available quite yet current
3:37 projections have 5G hitting the market sometime in 2019 with it becoming
3:42 widespread around 2025 since providers not only are trying
3:48 to make 5G a more uniform standard than
3:51 what exists today to ensure better compatibility around the world but they
3:56 also need time to build more infrastructure that infrastructure would
4:00 include Signal Boosters since 5G shorter wavelength means it's more prone to
4:05 Signal degradation across great distances but even though most of us
4:09 will have to wait a while to experience 5G trials are already underway in a few
4:14 places in the United States and small scale deployments are expected at the
4:19 2018 and 2020 Olympics to give attendees
4:22 an early look at the tech before it reaches the mainstream so in summary
4:27 don't chunk your LTE phone just yet but don't be surprised if in a few years
4:32 whatever you're carrying in your pocket ends up putting your home internet
4:35 connection to shame tunnel bear VPN lets you Chunnel to 20 different countries
4:40 allowing you to browse the internet and use online services as if you are in
4:44 that different country they have easy to ous apps for iOS Android PC and mac and
4:49 also have a Chrome extension so that it's made for you just choose a country
4:53 in the app turn tunnel bear on and watch as your bear tunnels your internet
4:56 connection to your new location when you turn tunnel bear on two things happen
5:00 your connection gets encrypted with AES 256bit encryption and your public IP
5:05 address gets switched so you can show up as if you're in said different country
5:09 they also have a top rated privacy policy and do not log user activity you
5:14 can try out tunnel bear VPN with 500 megabits of free data and with no credit
5:18 card required and if you do choose to get a year of unlimited data you can
5:22 save 10% by going to Tunnel bear.com Linus all right guys if you liked it
5:27 like it if you disliked it dislike it check out Channel Super Fun because I
5:31 soon I'm going to be on there actually which I haven't really been on there
5:34 much lately and also don't forget to subscribe and follow because those are
5:38 good things to do
