How can we get help with the 5G network?
So, to help clarify things, we will explain to you, what exactly 5G is, how we got here, what the technology behind it is, and any real concerns that may arise about new technology. (cool music) So, what is 5G? Yes, 5G, or the fifth generation, is the next step in mobile internet technology.
These are the next wave of phones and tablets that will use them faster than the LTE networks we already have.
So all major carriers continue to roll out 5G, and by the end of this year, you should be able to get it wherever you live in the US, but what 5G says for each manager is different.
Speed is different, coverage is different, so last year I was testing all networks, Verizon, AT&T, T-Mobile, and Sprint are now part of that, just to see how fast and what a difference it makes in your daily life. Let me try to explain.
Now Verizon's 5G is burning fast; you can get more than one-gigabyte download restriction per second. That reaches up to ten times faster than most home wifi connections.
You can download the entire season of the TV program in just minutes, but the problem is coverage. Verizon's 5G is very spotted. It’s there in one street and then the next, and the inner coverage isn’t too much. That’s because Verizon is looking at its entire 5G system, meanwhile, in so-called high band millimeter-wave technology.
You’ve seen it in those ads like ultra-wideband 5G. But the problem is, the signal can't go very far, so in a city where it wants to roll out 5G, Verizon has to put all these bumps all over the city, and that doesn't help the whole country, so later this year, Verizon will also open.
It's low bandwidth 5G network, but when the speeds aren't much faster than your LTE phone can do today. So for now, Verizon's5G network is not eligible for the upgrade to a new phone, unless you have similar anodes outside your home or home.
T-Mobile has the most comprehensive 5G system for all US vehicles. It also uses millimeter-wave at the high end, as well as Sprint's mid-band spectrum in the middle, with its low 5G band at the bottom. Now Spit's mid-band spectrum is much faster than LTE today.
I was in Texas testing their 5G network and I got a speed of 300megabyte per second. And unlike Verizon, I could rely on keeping that 5G signal anywhere I go. Think of the distance as a fun 5G place. It's much faster than telephones today, not as fast as millimeter waves, but making a great day to make a difference today.
And last but not least, AT&T has the same strategy as Verizon, because you get a high-band millimeter-wave and low-band sub six 5G, but they lack that middle part of the cake, that spectrum in the middle of the band, so you'll have a faster speed in smaller parts.
of other cities and faster than your phone today everywhere else. Now, none of this should be confused with AT&T's fake 5G, called 5GE. You've probably seen it in your phone's status bar from time to time. That’s just fast for LTE.
It has nothing to do with the real 5G currently being released. These are still the first days of 5G. We’ve seen fewer than a dozen telephones arrive on the market offering this fast-paced new and some of the first ones were a big bug and hot summer.
Now that concern, as well as battery life, has been largely overcome by Qualcomm's latest chips. We've seen those chips on the Galaxy S20, the LG V60, and the OnePlus 8, all excellent phones, but we're still waiting for that first iPhone from Apple with 5G and rumored coming later this entry (Suggesting Music) - So when we talk about 5G, we are not really talking about anything very different from our current and past mobile technology.
Let's put that in perspective. The first generation of mobile technology, 1G networks, was introduced back in the 80s. Unlike other generations, 1G networks have used analog signals and can only make voice calls.
You have probably seen phones using 1G networks such as the Motorola Dynatac, that old-fashioned mobile phone from 80s movies. 2G networks kick things up.
More bandwidth meant that in addition to calls, users could start sending data, enabling messages, SMS, and photos, MMS.
The latest versions of 2G phones can even access the basic internet, like the most popular 2G device ever sold, the first iPhone. 3G networks offer more bandwidth even faster speeds, and 4G LTE, which is what most of our current phones use, making fast wireless internet possible.
And 5G, as Chris mentioned earlier, takes things a step further, at a faster rate in some cases than on home wifi. But the important thing is that all these technologies are not fundamentally different.
They are all based on the same science, which means it is time to talk about the electromagnetic spectrum. This is the EM spectrum, a diagram of the various types of electromagnetic radiation present. EM rays are what we call a wave of space photographs and all EM rays, be it AM waves, X-rays, infrared, or even visible light falling somewhere in the electromagnetic spectrum.
The difference between the harmful X-ray radiation and the negative AM radiation is simply the intensity with which it is located. Now, at the end of the stage is low-power radio and microwave ovens, which are characterized by low frequency and long wavelengths.
As we increase the spectrum, the wavelength decreases, the tides rise, and the amount of energy transmitted also increases. For example, AM radio broadcasts between 540 and 1600 kilohertz.
Low power, but those low wavelengths can travel amazingly, up to 100 miles. And depending on atmospheric conditions, they can expand the earth by blowing air. But again, the quality is poor. - [Publisher] We hear sounds coming from that moment, hundreds, or even thousands of miles away. - Climb up, on an FM radio that broadcasts between 88 and 108 megahertz, and you get a lot of bandwidth, allowing for high-quality streaming, but your usable distance is reduced.
It's the same basic concept as mobile data. New generations allow us to improve our transmission technology, which leads to increased bandwidth and higher bandwidth, leading to faster acceleration. But for the backbone, all the basic technologies that are the same with different types of 5G, actually reflect this well.
For example, take the AT&T and Mobile's low-band networks that Chris is referring to. They are at 600 megahertz and 850 megahertz, successfully the same spectrum area as the existing LTE, but the fact that they are new spectrum groups not yet closed with existing customers, combined with new transmission technologies, means that these low band networks 5G can provide faster speeds than LTE, even if they use the same spectrum bands as LTE.
And that's the nature of the band's low bandwidth, and that means they can extend over a much wider range than other 5G models. That’s why T-Mobile, for example, seems to have 5G coverage across the country, while Verizon is stuck on a few street corners. Next up is the mid-5G band, which is just used by Sprint and now T-Mobile, which owns Sprint. Available at 2.5 gigahertz spectrum, it offers faster speeds than low-band 5G but has a much smaller range.
By comparison, 2.5 gigahertz is about the same area of the electrical spectrum as your home wifi. Now, mid-band in the middle of the road in almost every aspect. It is a higher frequency and more bandwidth than low-band 5G, but it will be the speed and frequency you will get in millimeter waves, which is 5G faster.
These are now available at about 30 gigahertz, much higher than other 5G models and offer faster speeds; the ones Chris mentioned earlier are from Verizon and the limited areas, T-Mobile, and AT&T, but those radio waves are also very small, between one and a meter, which is why the name is actually worse than things like walls or buildings, meaning that the width is amazingly limited.
So even if it offers the fastest 5G speeds, and it is 5G you may end up using less, as a result of that output, it will be much smaller. But that increase in bandwidth is only part of the story.
Much progress in 5G, comes from new transfer technologies. Things like network collection, which includes multiple LTE bands for single-speed data streaming, or MIMO antennas, or multi-output inputs, where we use antenna configuration, made with multiple smaller antennas to improve communication. (cold music) But is 5G, or any cellular radiation safe? Yes, there has been a lot of misconceptions about 5G.
Some are completely absurd, such as the idea that 5G somehow created the coronavirus, but the simple answer is that 5G is basically the same as any other type of mobile radio technology and we already have a good idea that cellular radiation is harmless. - Well, people are a little worried about the potential effects of cancer formation if you use your cell phone too much or if you are constantly exposed to radiation from cell towers.
There are many studies available on that type of outcome, but that has never been it has been proven that there is indeed a carcinogenic effect of exposure to radiofrequency radiation.
There is also concern that exposure to radiofrequency fields, for example, high-density, high-frequency 5G waves should be used, which could have a negative effect on the immune system and that people could be at risk of becoming infected with the COVID-19 virus. There is no evidence, there is no indication that there are any effects on the immune system from exposure to radiofrequency fields. - Now, I know that cellular radiation falls on the wrong part of the spectrum.
Can you talk a little more about the difference between non-ionizing radiation and ionizing radiation? - Ionizing radiation is very strong and as a result, it is possible that when exposed to that type of radiation, those chemical bonds in the body, are damaged and broken, and that can lead to uncontrolled cell growth, which can lead to the formation of cancer.
This type of effect, the separation of chemical bonds, is impossible with non-ionizing radiation, which is a type of radiation used by mobile technology because the energy content of that type of radiation is insufficient to lead to such chemical separation.
The whole spectrum of non-ionizing radiation, up to UV radiation, is something that does not have a high energy content to break down chemical bonds. Heat is the only guaranteed effect of exposure to radiofrequency radiation. (cold music) - While 5G does not pose a health risk, there will be practical problems with switching to 5G.
Some of the growing pains are simply shifting to a new generation of technology. Things like more expensive programs. Fast data speeds mean you can burn your data cap very quickly, and that's what we need to understand. The first 5Gphone wave was very expensive, although prices are starting to fall. And of course, it's just about building networks.
The low bandwidth of mid-band and millimeter-wave networks means that it will take longer and cost more to build more towers, to get that kind of coverage that people expect. The good news is, we have already started. Qualcomm, for example, has made 5G a default for all its new chips and leading phones by 2020, from companies like Samsung, Apple, OnePlus, they may already be shipping via 5G, or they are expected to have it by the end of the year.
And that doesn’t mean anything about the huge advances made by carriers like Verizon, T-Mobile, and AT&T in building real networks. And most importantly, none of these problems are really new. Switching from 2Gto 3G, or from 3G to LTE, has seen similar problems and the technology industry has been able to solve them.
The only difference is that we rely more on our phones than we did 10 to 15 years ago, which is why these problems seem so important now. But the important thing to remember is that 5G and the surrounding technology are not really new. It is our opinion of them, and our reliance on our phones has really changed.
