One of the big things is the use of TDD instead of FDD communications which makes much better use of the available bandwidth and gives higher throughput. Our company was testing a 5G mmWave Verizon system in Las Vegas and was easily getting 1.6 plus gigabit download speeds. People also ask why the drive to such ridiculously high bandwidth systems like this? Well for starters when lots of people share a common resource, having super fast download speeds helps reduce the latency to ALL the users, which opens up new technologies like realtime telepresence and robotic control to name a couple.
It’s also good to keep in mind that they need to future proof 5g to be usable for around 7-10 years.
Ah, AT&T! Spent a quarter of a trillion dollars on Directv and media networks when they could have spent it on fiber and cellular infrastructure.
makes sense
Is this a German company? 😂
Why they don’t use DirecTV satellites to also offer satellite Internet and phone service is clearly beyond me. AT&T has the infrastructure but isn’t using it, and I say this as the son of a former 30-year AT&T employee.
@@kennystrawnmusic One, those satellites only really support downstream data flow. Two, those satellites are in geostationary orbit. The way satellite internet works is you send a signal up, its relayed to an unlink center and then back. The total distance is like 88,000 miles. Even at the speed of light, that trip takes a good portion of a second. Pings anywhere from 250 to 1000 milliseconds. Lastly, directv doesn't own all its own satellites. Ecosphere, the parent company of dish network, owns a good portion of them.
The fastest way to do things in with a wire. I say this as a former technician of AT&T, Dish Network, and Spectrum, having installed and repaired coax, twisted pair, satellite, and fiber optic based internet systems.

Awesome video! Really good explanations.
One thing I wanted to say that I find a lot of people assume, the higher frequency is not the sole reason why data speeds are faster. There is just more bandwidth available that can be used due to how things are split up. In theory, if you had the entire 100MHz bandwidth of low band 600 MHz, you would get the same data speeds as 100 MHz of C-Band.
The higher frequency is _not at all_ the reason for more throughput! RF bandwidth is the _only_ consideration for throughput. The frequency itself can affect propagation, but that's line of sight for all the cellular spectrum. Before cellular, C-band was regularly used for distances of 22,300 miles, and S-band around 2 GHz was used to carry signals to the moon and back. It's the Ka-band signals that have problems with propagation, being unable to pass through windows, and experiencing significant fading in bad weather. Other than that, one MHz is the same as another when it comes to data throughput.
@@StringerNews1 isn't that what I said? I probably should have been more clear.
@@AndrewMackoul yes, that's what you said. But you did qualify it a little. I wanted to point out that there's no basis to believe that higher frequencies somehow carry more information. Bandwidth and SNR are the limiting factors.
I presume you know at least some of this but for others reading these comments it may be confusing. Frequency does have an effect on throughput (usually called bandwidth though technically different) and more importantly latency.
Modern cell phones actually use a very complex method of encoding data that combines frequency modulation (FM), amplitude modulation (AM), compression techniques, and more. With amplitude modulation the value of data is determined by the relative amplitude or strength of the wave when it arrives. Frequency modulation sends different values by sending different frequencies within a range, this range is the actual bandwidth but doesn't determine the throughput by itself. These are the same AM and FM found on radios but combined in a clever but also (honestly) very confusing manner that allows for much more data to be sent while also accounting for errors caused by interference. Regardless of what type of modulation is used the values per second is directly determined by the frequency. For example 1 GHz sends 1 billion signals per second while 2 GHz sends 2 billion signals per second, the actual bit rate depends on how those signals are modulated/interpreted. Lower frequencies can get the same amount of data out in the same amount of time (on average) by increasing the size of the bands (the bandwidth) to compensate for the losses caused by the signals literally being sent at a lower speed but the latency of the signal, that is how long it takes to send 1 signal, will still be lower. For most people and most use cases the latency in the mid-range bands will be acceptable while nationwide bands (those that can send signals 20 miles) will have a noticeable lag especially for things like video calls or online games.
You know, I like how all kinds of cool tech companies sponsor Thio. Very few VPN sponsorships. Legitimately one of the only channels that gets me to watch the sponsorship portions.
The app he featured here just basically captures your income, which is already simple to do..

Not only satellites use the 4 GHz band. So called radio altimeters among other things on (some) airplanes operate in close proximity to where 5G antennas. Thereof the ruckus previously.
You forgot to mention the conflict between the FCC and FAA over radio altimeter interference. Radio altimeters use radar to determine how high aircraft are off the ground when on approach or on departure from an airport, and when their readings are disrupted they can negatively affect auto-throttle systems. This has been a major factor in plane crashes before - Turkish Airlines Flight 1951 is a case in point.
One of the side effects of this of course is that C-band coverage is banned on approach paths - so if you’re within range of an airport you might need to wait a bit longer.
Thanks for explaining how the auction was performed and implemented. I've been looking at this auction from the aviation side with interest, as it lead to quite a few problems. Hope these problems get resolved and benefits the community!
Thank you. This was a very informative and interesting breakdown of 5G 😀
It's so good to see comment section with real people talking about the video
Thank u Joe
Thanks for the info Joe. Good stuff to know.
Thank you so much for this in-depth video that somehow fell on my page the recommendation I'm not even sure why I'm seeing this video but it was very informational and well thought out I like how you have the different chapters
Very informative and well-presented video.
Hey, I Love your Videos!
Keep up the Good Work!
Dude I love your videos because it's easy to focus on because sometimes I need to know something or just want to know something and sometimes you just don't want to sit through it but because the way you talk like the speed and the cadence and everything it's just like in an instant the video is done and you know everything even your sponsors sections are great and the way you pop up things on the screen are perfect to help explanations and you don't ramble off either losing focus keep it up man your vids are great 👍 Not to mention all your vids are bangers also you got me with one of you old fake vids but it got me into your channel
yesterday from LTT video he talk about ur YTScam app. im so happy after see that. bcus i learn so many thinks from ur videos. Good Luck! Buddy 🙂🙂
t mobile is absolutely in love with n41
i love being tracked more accurately.
Jokes aside, This is why I use a custom ROM and switch off sensors and turn off all my radios when my phone is not used
This also allows for home 5G service. with speeds that can rival the cable company. I have the Verizon 5G service on order but the device is on back order. they are offering 50 (with autopay). Currently paying spectrum 75. So if I can get decent speeds I can save 25 dollars a month. Hopefully the competition will be good for the consumer.
we already have that its called Fiber and is much more reliable and safe.
@@HamguyBacon Fiber is more reliable, safety isn’t affected with either option.
@@HamguyBacon Not everyone lives in a city center with competition. Even RDOF still leaves some people out.
i really love your video thiojoe
Me who is listening this that is not gonna have 5g in 8 years: visible pain 😢
Awesome video
What's poppin Thio!
Very informative.
First time hearing this C-Band. Thanks, I learned new stuff again
Recommate actually sounds like a good idea, now I just need to get some friends!
My cell company, Rogers, has both n41 and n78 (C band). Funny thing, when I go out the back of my condo building, I get 5G+, which is C band, but only 5G out the front. A few blocks away, I get 4G+.
Incidentally, long before satellites, C band was used for terrestrial microwave links, usually by the phone company. However, that has largely, if not entirely, been replaced by fibre. Also, several years ago, some people would directly receive C band television signals, though that was not the intended purpose.
That guard band wasn't implemented properly by one of our carriers, really buggered up out CBAND receivers in a few communities. Huge PAIN in the butt.
Also had to buy filters to reduce the receive power that was overwhelming some of our dishes. 😬
Good job with the video BTW. 🙂
I haven’t watched you in YEARS. I thought this was one of those BS videos you used to do 🤣😭 love it
The sea ban is really 5G NR the NR stands for new radio it is the UWB portion of the 5G spectrum which requires a line of sight the issue with the airports is that it operates near 2.49 GHz to 2.5 GHz which is close to the radio altimeters frequency.
Sea ban 💀
Voice to text doesn’t live up to its own advertising.
C band doesn't need light of sight. That's mm wave
@@thetechlibrarian
AT&T and Verizon recently turned on their C-band 5G networks after months of dispute with the airlines and FAA. And, knock on wood, so far we've seen neither major flight disruptions nor any danger to air safety.
After two years of AT&T's and Verizon's "nationwide 5G" networks feeling much like 4G, C-band could finally majorly multiply speeds. But what is C-band, and what does it mean for 5G? Do you need a C-band phone? Is C-band a new frequency? Should you be scared of C-band? We can explain.
Recovering the Satellites
According to wireless testing firm Rohde and Schwarz, the C-band is all frequencies between 4 and 8GHz. When US wireless geeks talk about C-band, though, they're talking about 3.7 to 4.2GHz-and specifically, in this case, the range from 3.7 to 3.98GHz.
This frequency had been used for satellite TV since the 1970s, but as C-band satellite reception requires "big, ugly dishes" up to 10 feet in diameter, it got largely replaced by more flexible systems with smaller dishes on the Ku band, such as Dish and DirecTV. C-band is currently used for the "satellite downlink" for broadcast television distribution.
With more advanced methods of digital encoding than they had in the 1970s, the satellite companies can now "repack" their broadcasts into the upper portion of the C-band, leaving the lower portion available.
And yes C band does depend on line of sight.
@@kalitor217 I mean that looks like copy pasta from somewhere, anyways, maybe it does. But not like millimeter wave where you can hold a piece of cardboard up and watch your speed drop in half c band at least goes inside of buildings.
I wondered what the UC meant by the 5G symbol. Thanks!
It's the next BIG thing!
Currently watching this video over C-Band n78.
It‘s definitely way better than mmWave and has around half of the speeds. TDD is something new for Europe, but we began rolling out C-Band before the US. The propagation issues mmWave has are there with C-Band, but I‘m currently in a building and I have 3 bars and 256QAM. The connection is reliable.
So I believe, C-Band will bring big changes (in Germany we too are currently really starting to roll out n78).
So I found out a few weeks back that (at least on android) you can download apps that force your phone to connect to specific bands automatically. So I forced my phone to use the ATT mid-range bands exclusively and no joke I was getting 40 mbps *on LTE!* Had to disable 5G to do it (something many carriers won't let you do out of the box without installing third party apps or rooting) but honestly don't see the point anymore if I can get 40 mbps on just LTE alone.
For those wanting the app, apparently it works differently with different manufacturers and carriers so unfortunately there is no one size fits all app. Also I had to re select the bands again after my phone updated. For my samsung s20 fe 5g i used samsung band selector, but you're going to have to look up an app for your specific phone. You may have to root for all I know...
Also for those commenting that this is built into android already, yes it is, its just that many carriers lock you out of changing those settings, including ATT.
I'v measured speeds of up to ~146+Mb/s, even 4G LTE is very capable of questionably high speeds. The phone I have supports LTE MIMO and I'm very close to a AT&T tower (+
What is the app??
I got 55mbps speed on LTE on mountain roads (where almost no residence and around 70km/h travel speed two lane highway)
I can not get these speeds at city centre and I think companies prioritize more expensive cellular plans to use higher bandwidth
3G was faster than 4G at my home due to almost empty cell usage I guess
Please tell me the app, my phone could really use something like this
@@namelesswanderer5274
Samsung band selection for samsung phones.
Network signal guru for other phones but you need root for this to work
Mid Band 5G has the potential to take place of mmWave in towns or areas that don’t have any mmWave panels. I’m able to pick up 1.2Gbps on just mid band alone on T-Mobile in my town, when I was picking up 1.8Gbps on T-Mobile mmWave near downtown.
In New Zealand we use C-Band and see Gb plus speeds each of the 3 main carriers have 60Mhz
It is almost 12 night here, i was doing my work, but just jumped to your video,
Good for keeping it in the background
i am located in one of those areas. last week my 5G phone speed was 327 Mbps. Wowza!
interesting to see this as soon as i hit the youtube home button
It's nice to know the meaning
Let's not forget that this auction also impacted the airline industry going as far as flight cancellations. The new frequency spectrum is quite close to the radar altimeter radio signals used by airliners and it's not yet proven that the 5G signals don't interfere with existing hardware. Until the old radar altimeters are tested and re-certified some planes may have to divert because they can no longer land automatically in low visibility conditions.
Altimeters and radar are a huge waste of valuable bandwidth. Look how much of the spectrum is taken up by radar and inefficient, low utilization, legacy services.
@@briank10101 Well things like that make the airline industry as safe as it is today. New products in a different frequency spectrum first need to be certified and then installed which takes time. Could take 10+ years because aviation moves slow.
Tbh is it just me or 4G/3G good enough?
3g is being shut down
not for self driving cars
@@kayciestraub then why is 2G still a thing? 🤨
@@raznemon Really? 2g is still around? I read ab article about how 3g is being discontinued
@@kayciestraub I think it's for america and other big countries, also if it said discontinued they might have meant that they companies aren't doing updates on them anymore.
I do get 5GUC in quite a few areas now. Just started a few weeks ago I think.
Aaaaand that explains why my coverage drops all the time. I am stuck on 5G and nearly half of a day, phone says 5G, but apps say not connected....
Very nice 👍
It's likely unconsequential, but what about short-wave radios? ("walkie-talkies")
AT&T is doing there one touch tower upgrades strategy
They waiting for dual band equipment to be available late spring/summer and then they will install them
you deserve a like share and a huge subscription
It may be exciting for 5G users, but us C-Band hobbyists are now losing spectrum, on top of OTA antenna spectrum we already lost.
I have read and heard there are significant health implications of the emf from 5g, more so than current cell energies. What is your understanding?
How is the current status on full 5G deployment outside of the US?
Couldn’t help not commenting here. Eye EeEeEe’s actual pronunciation is Eye triple-Ee.
Yea that sounds easier
@@ThioJoe Great work Theo Joe. Have been watching your videos since those “download more RAM” days! Keep up the good work!
Yooooo linus used your spammer purge program
that graphene should start to tickle now
According to Mentour Pilot, a channel covering airplane issues and air accident investigations, airport uses some frequencies around 4GHz resulting the bands C3 and C4 (above 3,7GHz) will not be allowed to be used around Airports. (In Europe frequencies above 3.7 have not been given to Cellular phone providers)
🐐🐣☃️😀🌞
I think India will most probably make use of 3.3 to 3.7 GHz. So no C-band here.
Since not much of a different, will 100 MHz block of it will provide equally good speed ?
Hi thio I hope your seeing this
As on RUclips shorts there are alot of bots (ALOT!) that spam upload the same video (example what setup are you going to buy from v-bucks, people who don't like vs people who like, Minecraft animations) and my theory is there probably going to get subs from kids/outher bots and after getting the verification tag there going to spam comment
belgium be like: we haven't even started selling the first set of frequency bands
In Australia if you buy an iPhone you don’t even get millimeter wave
I feel like this will interfere with C-Band Dish systems. Also Satellites have KU-Band as well.
And weather stations, airport control systems and healthcare buildings. What a great technology right?
will this be also available in eu or is it just us thing?
Can you do "What happens if you delete ProgramData"?
AT&T is waiting for equipment to be able to broadcast 3.45 and 3.7-4.0ghz for c band so they won't have to put two separate panels.
Boy, after watching this video, I'm now glad that I didn't pony up for an expensive 5G phone. Unless you live within those 46 areas, it's best to wait at least 2 years before getting a 5G phone, which will then run on the C-Band.
Or if you’re on TMobile. Ever since I got my iPhone 13 PM like a couple weeks later I was getting their 5G UC in lots of places around my town. Now it’s almost everywhere. I can get anywhere from 300-600mbps and have been able to for months. I’d say even though I didn’t buy my phone for 5G capabilities, I’m super glad it has it.
@@QajsProductions I bought my phone when 5G first came out and opted for one that doesn't have it. That said I'm not disappointed, the most data intensive things I do on my phone are listen to music and watch the WAN show while on a walk (if I'm caught up then I just listen to music though I have been meaning to check out some other podcast).
is it same as C Band used for satellite TV? 🤔🤔🤔
Sir which software (free) is best for video editing.
Congrats on getting featured on LTT for your spam app!
I have been getting 400 to 500 mps everywhere in my area.
My worry with 5G is how easy people can be tracked with it. I think that phone numbers need to go away and instead communications should be done online by end to end encryption over voice or something similar. (This probably won't solve the problem thought.)
Yes, 5G includes tracking for beamforming purposes but they can already track you with the base station you are connected to.
they can already do that with 4g but with 5g its more closer also end to end encryption doesnt hide which tower you are connected to
@@realcartoongirl Yeah, it's just that they had increased the towers even more with 5G so it will be even easier for them.
@@lityum2779 And even more with the increase of towers as 5G need more of them.
Thio resetted my laptop and now Microsoft store is missing I've tried to many ways to get it back I cant seem to find a way🙁

Hay thiojoe, I need a little help on a little tech stuff. How to fix a slow android because of Wi-Fi and my service isn't the fastest were I am I have at&T and I get 2 to 3 bars and my downloads are about 40 mbps and my uploads are about 20 mbps or slower. Please help
In Canada, we are still years behind in Rolling out 5G. I don't think we will see C-Band anywhere in Canada for the next decade. Our government is still fretting over announcing a public ban of Huawei. We still have a lot of Huawei equipment that needs to be replaced in the core network and the government is not funding its replacement.
My question is, with the frequencies getting so high, will it affect the human body?
the only difference with 5g is it looks cooler when you screenshot something as the status bar shows 5g other than that i get slower speeds than 4g+ and with 5g speeds were less consistent, slower than 4g. At least in my country
Higher frequency = less distance. Wifi 5ghz for example :)
New video. Great ❤️
@ThioJoe
What if you use a virtual machine inside a virtual machine
I don't think we will see mmWav until they incorporate it into consumer internet, Wouters. But in Canada, we will be deploying 6G before we see mwah, so until after 2030!
None of the Canadian carriers have anything like C-Band designated.
I would guess B1 is currently being used as a temporary Guard Band.
You might be right, that would make sense
I think att doesn’t care about this because they have free high speed hotspots pretty much all over the country for customers.

I noticed yesterday that my SE2020 was displaying 5G-LTE. I know my phone doesn't have a 5G modem in it so I guess it was just showing that 5G was available though I am actually getting LTE?
Do you have att?
I'm still struggling to understand any meaningful use case for 5g, even if it was faster, what am I going to download? We already stream video at plenty of quality for a phone sized screen. Not to mention that anywhere that we're spending long enough in place to get the millimeter band could and probably does just have wifi.
Selfish, greedy people who complain if a website doesn't load it half a second, or instantly.
5G cellular could be a competitor to cable Internet service.
It's not so much speed as capacity. Also the ability for them to offer fixed wireless broadband since there is virtually Zero competition for home Internet in a lot of areas
Hey man everything is working on my pc except the fans all of them just shut down yesterday idk why
Me neither
Yay a new video
Great work Thio, will I need a new 5G phone or device to take advantage of this ?
What about visible?
Isnt the same c-band in satellite prodcasting?
Watch the video and find out ;)
@@ThioJoe 😅c-band can still work even whin rain fall not like ku-band
What about US CELLULAR?
As a satellite TV user, I am FURIOUS.
Satellite TV basically uses 2 bands. C band is 3.7 to 4.2ghz (total 0.5ghz)
And Ku band is 10.7ghz to 12.75ghz (total 2ghz)
The more spacious ku band is used by dth companies which make us pay to watch ad riddled television,
And the narrow C-band mostly has free channels.
And now they want to make the already narrow C-band even narrower???
That would mean they need to use more satellites to spread out the channels.
Which wouldn't affect Cable TV operators because they can afford to use more hardware. But for us home users, it'll get crazy expensive to tune multiple different satellites to get all the channels we need!!!
What exactly prevents anyone or any company from tapping into radio spectrum without a license or permission from the FTC?
Technically nothing in particular. I work for one of the Sattelite companies that had to migrate our c-band implementations, so I can only speak from the satellite perspective. In short it would cause interference, transponder saturation, downlink demodulation issues. Pretty much unhappy paying customers not getting service the paid for. Exploratory teams can be sent out based on the affected satellite transponder regional footprint and the offender can have their location triangulated by antenna looking for matching transmission characteristics. Then the legal stuff starts. Fines, cease and desist, etc
@@WatchForReptar Yeah that is a likely outcome. But only matters to people who give a damn. What if the offenders are using a mobile pirate transceiver? Or placed decoy equipment that can be remotely operated to throw such teams off their trail. Or out of some weird cat and mouse type game?
But what about the people that don't live in the US?
yeah let's spam all our friends and family with "ads"... WUT?!?
4G seems plenty fast, never had speed issues. What exactly do we need the extra speed for?
More Capacity for everyone and lower latency.
@@niklas8565 we don't
