Loved the delivery, but missed some other big things
1) Wifi 6 brings beam-forming to 2.4ghz
2) Wifi 6 devices are allowed to "talk over" another device as long as the other device has weak signal strength. This reduces competition for spectrum in high density areas.
3) Wifi 6's new signalling reduces the latency quite a bit. Something like 1ms instead of 10ms. It doesn't sound like much, but when you have packet-loss and the wifi frame has to be resent, it can be the difference between 5ms and 50ms.
4) Wifi 6 can do full duplex if the devices support. The protocol supports it because of OFDMA
Nice
Excellent! Thanks Benjamin!
Didn't know about full duplex, that's going to be a game changer for a lot of home devices. Now I'm actually excited for this!
@@AluminumHaste Because of the OFDMA sub-channels, there's no functional difference between something sending and receiving on different sub-channels or more than one device sending on different sub-channels.
Of course it is up to the devices to take advantage of this.
@@shawnbechard3680 I'm not gonna say what you're saying is wrong or incorrect, as I'm sure its based off of experience with a certain standard of internet that many likewise have.
But (and I left a question about this for @NetworkChuck) for people who don't have a certain level of internet speed, this change in delivery protocol could make certain peoples lesser (and only real viable option) internet speeds more effective.
Which if it does, then I could see where you're coming from with your perspective; but if it does it would def. help people out like me who only have a max speed of 8mbps. (some have even less)
29 years old and I've never seen anyone get the point across so easily, and at the same time make it so interesting. Loving the vids so far man keep it up!
Am a computer science student I graduated from university and one thing I can confirm is that what I've learnt all this years from Google and CZcams is more valuable than what my lecturers taught me back at school 🙌🙌
Hello chuck I want to ask you what do you think about window 10 or 11 in s mode?? Is really worth it?? Is it a lot more secure than the normal mode
School is a scam 😂
You'll learn 10,000x more from real world experience than you will from CZcams or a school or Google.
He is such a good teacher.
I just amazed how his presentation drew my attention till the end of the video
Where the hell did you all find this guy? He's great a teacher at heart, I subbed
Yes, we love Chuck!!! Btw he used to work for CBT Nuggets so that is where some of us found him. The first time I saw him I was researching Cisco certs and he had a video on that. Then later I watched him on CBT. Always enjoy his videos!
I think I got a random CZcams recommendation, and I saw a nice video thumbnail so I clicked it and discovered greatness.
Right on, the man can teach! Information is solid and well researched, his energy is great and most importantly he can break it down into digestible forms with analogies that make sense to anyone willing to listen. I subbed too. All teachers need to watch this guy just to learn how they could be doing their job better.
i found him pretty early and i can tell his video quality is even getting better over time
he's good i subbed too
NetworkChuck: Just as long as they don’t make the next standard Wi-Fi 6S
Wi-Fi Alliance: Hold my antenna... Introducing Wi-Fi 6E
:))))))
Nice video.
QUICK TIP; if you want to get rid of the color cast you're getting when keying out the green from the drawings. Try drawing on a black background and using the "screen" blend mode option instead of chroma keying.
Public WiFi isn't bad because of current WiFi capabilities. ac is great.
It's because providers of public WiFi deliberately throttle throughput bandwidth and speeds because they're cheap.
Agreed... I've been to many conferences where the AP can handle hundreds of clients, but it has a T1 connecting it to the internet... that is 1.5Mbps if it's a full T1. Try sharing that with hundreds of clients over WI-FI 6. WI-FI getting better is great but we need faster connections to feed it.
Isn't this shocking that conference halls are so cheap? I just finished a restaurant setup with a 400x100 fiber connection and multiple Ruckus R710 AC Wave2 APs. No throttle. Guests will be FLYING.
I was literslLy going to say this but I didn’t think I would have a voice. Thanks.
My previous job we hosted wifi for 90+ sites ranging from 1 user to 100s, i can attest to this. Public wifi backhauled to the data center which fed that traffic oit of 1 cable modem, eventually upgraded to 2 with loadsharing to a backup DC, but still capped each device at 4Mbps to jabe some control over the thousands of devices connecting at once across the MAN.
Rob,
I was just about to say this same thing. So if you thought it, I thought it, and I'm sure may others here did also. Why is NetworkChuck forgetting to speak about it in this video?
I just started preparing for CCNA and your channel is really keeping me motivated to get into the network-world. 👌 Thanks for all the effort you are putting in this.
Also keep in mind cisco may within the next 5 years could very well be irrelevant. I say this with a notation though it is always very good to know how the back end of things work but going forward Cisco is completely changing the way that they do routing switching and that working from the ground up
GUNATAV KAPOOR. I would study Cyber Security or Data Center track from Cisco. R/S is great however the network pioneers layed the Backbone done. Cyber Security and Data Center is the future. I recommend TCP/IP Illustrator volume two. To prepare for your CCIE studies.
@@balla2172 That doesn't make them irrelevant. It just means you'll have to keep up on the new technology and how things are done. This goes for anything in the IT world, and the reason why you have to recertify every 3 years. New implementation also does not mean all enterprise companies are going to switch over immediately. The old stuff will be around longer than one thinks.
@@DrZiggyzoo1 all of our clients are on a 5 year cycle and going forward our standard going forward is 9000 series switches
Learn routing, switching, firewalls and WiFi - NOT just how Cisco does it. You need to realize Cisco does things different - for example, every other switch vendor besides Cisco uses tagged and untagged VLAN language, not access and trunk. Literally, Ruckus, HP, Dell, Extreme, even Cisco SG series, etc ALL use the same VLAN language, Cisco is the only one that does things different.
So my point it, learn network concepts and fundamentals, not just learning “Cisco”. Probably only 4 out of 10 customer I do work for in a week use Cisco.
Edit: I also have my CCNP in R&S, so I’m not bashing Cisco, Im just saying I see supposed “network” guys all the time who can’t work on anything but Cisco.
Bro Alexa is like your buddy here. “Smart.”
“Thanks.”
I’ve never seen Alexa do that 😂😂
You can not see Alexa....
Dejv I’ve never heard Alexa do it.
It's an optional setting called "Follow-up Mode" which allows Alexa to continue listening for a few seconds after the initial command/request for additional commands/requests. Pretty handy. Besides, it's only polite to thank her once in a while (or in this case compliment her). ;)
5:40 the Bob Ross of networking. Haha that's awesome
Me: * just upgraded home wifi *
Wi-Fi Alliance: Wifi 6 is out now
haha i'm there now but 6 is just now gaining support for home devices while in the enterprise space it's still rare or non-existent.
I'm too
Me too. Bought a AC5300 and then few months later AX6000 and AX11000 coming out.......
I hear you brother. I decided to wait because I worked for Tigerdirect and heard the standard was being upgraded.
Thanks for admitting that this video is sponsored by Cisco.
I must confess that I ran out and bought a 802.11ax router as soon as one became available, and while I'm excited about this technology, its biggest impact will not be in the home, but (as you mention) public WiFi when you have a large number of devices trying to connect.
I'm not so sure about that Paul. I do SOHO networking support for Comcast and I regularly deal with 20 - 40 devices connected to a single AP. And they wonder why their wifi is so slow, lol. Wifi 6 is gonna put me out of a jerb!
Even a moderately sized family can easily stretch the limits of even the highest end AC routers. If you have 3 or 4 teenagers who regularly bring friends around then your network can get pretty congested.
Yes... BUT you have to consider that companies still want to make money and upgrading all of those routers and networks to wifi 6 costs money that they could really not give a flying fuck about giving customers free wifi... so yeah... it's not that it will make a difference in public wifi it's that it may make a difference if they even upgrade which for malls or airports... is unlikely. Businesses are more likely to upgrade yeah but I dont see it happening for quite some time now like maybe itll happen when wifi7 is a thing
@@technimechanical Plenty of companies care about giving customers good wifi. If the difference between Coffee Shop A and Coffee Shop B it that Coffee Shop A has much faster wifi, well guess which one customers are going to flock to. Same for hotels and the like, especially for business customers. Public image and customer ratings make a huge difference is corporate spending patterns.
Frankly, my home has 20+ devices connected to wifi now, and I am using rdp over wifi to watch this. This will be very useful in my usecase, as soon as our devices are upgraded. I assume wifi 6 needs new devices to utilize all these benefits.
the hub -> switch reference took me back to the days I upgraded my hubs....right in the feels man.
I was wondering how many would know the difference between a hub and a switch.
@@RandomTorok that broadcast though lol...
This got me psyched up too!!
The hub/switch analogy is what turned me off wifi way back when. At the end of the day there are lower and higher layers of technology where a controlling factor can be addressed. One could muck about with wireless modulation and multiplexing, or one could run a more reliable and isolated channel. I'll pick a dedicated interface when available, any day.
This video is 4 years old, but I JUST upgraded my AT&T gateway router from 802.11AC to AX, hoping to help with the congestion in my neighborhood. Before watching this video I only knew that WI-FI 6 is faster, but had no idea of the impressive features. Thanks for posting this!
Tried to learn from many sources about Wi-Fi 6. But none were close to what I learnt from this video. Thumbs up to your delivery and the way you presented all the features.
I'm surprised that I didn't hear anything about mu-mimo
I understand the concept between the two and yet they are similar, but based on the actual technology they are two different fish.
still don't see much instant improvement based on older devices.
The mu-mimo focuses on the downstream and OFDMA does both up and down.
I did initially think the same as you Chistopher and I also get a sense of "YourMomDotCom19" propaganda.
Wifi 6 routers use something called OFDMA (Orthogonal frequency-division multiple access) to send to more than one device simultaneously. So MU-MIMO isn't needed.
Hanging out with CBT Nuggets members improved your explanational tutorials I can notice. Well spent time Chuck. :)
“Maybe one day, none of us will be in the office.” - Pretty apt observation, Mr. Network Chuck! It came sooner than any of us realized!
The green screen in photoshop move was genius, I am glad you showed the view to let me see that :)
I have watched 10 videos about wifi 6 and didn’t understand it you explained it amazingly great job(I finless understand it )👍🏻❤️
Lol.. “one day we’ll all be teleworking from home” Welp... it happened
@SoulWorthy okay.
You did not over-flog the subject at all, every point was still important all 24min.
Thanks NetworkChuck
Talk about making boring and abstract tech stuff so simple and interesting, this is so much fun to watch. Good job NetworkChuck.
Makes you angry does it? Wait till you find out that each core on your computer only runs one program at a time and it just switches between them giving each a little compute at a time.
Yeah multi tasking is not really real multi tasking lol I learned about this in my CS class and was blown away. I bought into this for so long thinking it was really making multiple tasks on the process, instead of switching between one program at a time to give it resources.
@Jordan Rodrigues Imagine air hockey except there are multiple pucks....lol
@Jordan Rodrigues Like programs don't need to use the time slice either? I mean like messenger would not have to acces the cpu more than once every second when idle. Adobe does not need to acces the cpu 4000 every second when the program isn't even running and so on.
they are all retards. probably will have to wait for china and russia to release a competitive architecture out of spite for these limitations!! In the end it is ALL warfare. we are a war mongering species in everything we do.
Actually this is not exactly true. A CPU core can run multiple instructions (from different programs) at once via SMT.
This may be the best tech video I’ve watched ever
Not sure how you popped up in my boring feed but MAN your content is AX
cool tips , wifi can be a bit confusing , but then again follow this tips: avoid placing it near metallic surfaces, dont place it too high or low, dont place near wet places ( bathroom ) , avoid obstacles , be aware of nearby noise ( microwave, wireless phones ...) , make sure your antennas are 90 degrees perpendicular to the ground....bottom line, it is more than pure standard
I'm not saying ax/6 won't be better, but isn't MU-MIMO already allowing simultaneous communication of multiple devices?
As I understand it does, but this looks like it'd improve the multiple antenna devices even further because even they could only talk, per antenna set, 1 in and 1 out, per 1 device at any given moment - as I understand it.
There's vanilla MIMO and then MU-MIMO. MU-MIMO has multiple pairs of input/output's and permits them to all function simultaneously.
MU-MIMO 802.11ac supports multiple users downlink(!).
@@needsomehike Gen 1 perhaps, Gen 2 support allows more.
@@Enonymouse_ Hi, E. what do you mean it allows more? WITH Gen 2 (are we talking about wave 2 ?) the AP can receive from multiple users ? If so can you please include a white paper or link ? I am preparing for my CWNA and would like to be up to date before exam day.
This could have been a 2 min video
I appreciated the background explanation.
Hi Chuck, I just want to say that I appreciate you and your videos. You really make all of the IT stuff approachable and make it all of it seem doable/learnable.
Every hard definitions just turn out so easy to understand. This is insane!
I love how enthusiastic you are about this. I know Jeremy from CBT Nuggets is the same way. If everyone were as helpful as you two... the IT world would be a happier place.
"One at a time, before AX" - that's not true, MU-MIMO exists in AC.
was just coming down to comment that
And is crap compared to AX
Jeez, man! Gotta say, you're the best teacher I've ever encounter. Absolutely best tech video I've ever seen. Thanks a lot, dude.
Wow. I'm not even done watching this video yet and I had to pause it so I can comment on how great you are at explaining this! Dude...I shouldn't even disrespect you by saying dude but I would pay to sit through a classroom as you teach us this new technology. Very well explained and easy to understand. Keep the videos coming! Thank you.
Aren't you forgetting MU-MIMO is available in wifi 5 as well?
José Luís Lopes he didn’t talk about mu-mimo
@@adhame95 If I understand it correctly OFDMA is basically the same as MU-MIMO.
Laughing Orange no its a different thing
Ofdma works on a a frequency level
While mu-mimo on a spatial level
For example With ofdma the ap dedicate 1.5mhz of the 80mhz channel to a device that requires a little bandwith and 40mhz to another device streaming video.
Mu-mimo dedicate one or more)spatial stream(an antenna) to each device
For example if you have a 4x4 mimo
ap and 4 1x1 siso devices the ap will
Use 4 times 1 stream at the same time to talk to your devices, if you have 2 2x2mimo device the ap will use 2 times 2streams at the same time.
Without mu-mimo even with a 4x4 ap and 4 1x1 siso devices it will use all 4 streams one by one to talk with the devices.
Both technologies share the same goal but in a different ways.
Im not a network pro so i could’ve said something wrong, please correct me if you have more info.
Yeah, I was wondering why mu-mimo never came up... I'd have preferred to discussion of the impact of 1x1 vs 2x2 vs 3x3 device mix... That would have been more useful I think.
@@LaughingOrange OFDMA isn't even close to the same thing as MU-MIMO..
Hey man, i work for Charter Spectrum. I’ve been telling all of my fellow workers to give your channel a look. You give so many great sources and such amazing info, i couldnt help but share it. Thank you again man #beardbadass
Dude! Thanks Brad!!
LOL. I've mentioned him a few times to classmates in Network Administration.
The way this guy explain is just amazing. Totally love his videos. Keep going chuck.
literally pumping this video through wifi 6 right now
mu-mimo was to fix this as well
Mentioning mu-mimo in this video would be a good idea, because it's a Wifi 5 protocol that gets part of the way here. Some downsides to mu-mimo:
- 5ghz only (not 2.4)
- download (router to device) only
- less supported streams
i am so happy you guys came up with this. I am getting ready for my exam and this video confused the hell out of me. MU-MIMO 802.11ac supports multiple users downlink. Period!
needsomehike I’m glad I stumbled upon your comment, since I was confused as well and realized mu-mimo exists. I’m thinking WiFi 6 as a standard protocol will eventually be cheaper then adding mu-mimo to your access points, which is probably what will happen.
A couple of questions,
1. What about MU-MIMO, wasn't that supposed to allow for multi-device communication from the router?
2. Don't current AC routers allow for use of both 2.4Ghz and 5Ghz? Or is that true and it can only choose between the 2.4Ghz N and 5Ghz AC at any given time?
MIMO needs multiple antennas. This is an example with only 1 antenna. So, He is totally correct but with 2, 3, ... Antennas you can have multiple streams even now. But still a Big Highway at each antenna
MIMO has been around since 802.11n came in, but not all manufacturers implement it.
I think the issue with WiFi currently (upto 802.11ac) is the fact there are too many optional extras so to speak. You can be 802.11n or 802.11ac compliant, but not implement all the features.
1)Another thing is mu mimo in ac was only downlink meaning, ap to client not client to ap. As far as multi user communication, ax supports 2 technology - mu-mimo and mu-ofdma. And both of them supports both uplink and downlink communications. Each of this multi user technology has its own advantage and disadvantage.
2) 11 ac was defined to operate only in the 5 gig spectrum as per original 11ac standard. Any implementations of ac you see operating at 2.4 is actually not ac. It is just the vendor is lying you.
I got confused about this now. So the way i see it high end AP can support multiple SSID and with the 802.11AC wave2 it can transmit to multiple stations but receiving only possible from 1 at a time. So, what about multiple SSID each on different channels? Can multiple stations transmit at the same time to the AP provided that they are on different SSID-s hence on different channels?
My netgear c7000 has Simultaneous 5 and 2.4. For.some reason a new 2.4 Wyze device would not connect but it may have been a firewall issue.
Hell yeah man. That’s why I work for Cradlepoint
I got it now, devices I have support it. In the appartement building is a lot of noise. But now I have full ISP speed, absolutely maxed out, latency very good, no lags on any device. Perfect upgrade!
Finally! Can't wait till this rolls out!
Great video, super informative 👍🏼, would be much better if the topic took only 10 or 5 minutes max. Keep up the great work.
I am a Residential Technician for Xfinity, since we implemented WiFi 6 (802.11ax) modems, I have found that they are way better in terms of latency and troubleshooting. At first, the modems did have a couple of issues but they have since been resolved
Man your training is awesome. Your method should be trademarked. Thank you.
Nice information but was a bit of a drag with too much time for every small term...
He talks about wifi 6 but he explained it like wifi 1 speed, lol
I liked extra explanations. Just listen at higher speed if you want it faster.
Ummmm every detail matters corner cutting niney

CHUCK, I've been contracting for a hospital for a year now installing ethernet cabling. Every other patient room is red and blue networked and every 3rd room gets an opposite colored WAP. I've always wondered why they insist on this but now, thanks to your video, I understand that they are simply preparing for WiFi 6 and the new technology concepts. I freakin love computer networking. Thanks for all your videos. Fan for life lol.
excellent work Chuck! Would highly recommend anyone who wants to get up to speed on the AX standard in a short period of time. And, I love your analogies! I love explaining tech concepts by relating them to concrete laymans' items like mulit-lane highways (64 vs. 32 bit) or Matryoshka doll (encapsulation of the OSI layers). Thank you so much for the production work. :-)
I like how he randomly started playing VR while explaining
The background music should be a little lower in vol. , it is distracting,,, ✨
You taught me exactly what I needed to know about wifi. Great experience. Thank you.
Amazing explanation! If I only had teachers like you when I was getting outta high school I would have gone to college for the computer industry
How to explain something in 15 minutes that can be explained in 2...
Are you like this at parties? Do you dislike savouring an enriching conversation that allows you to enter a person's mind. Have you not explored, step-by-step, a way that a person thinks things through as the conversation progresses? Yes, he could have explained it in 20 seconds even (sometimes I too want informative quick videos), but for the love of god... you cannot expect every conversation to go in 10 secs.

This is by far the best explanation how WiFi6 works and what are it's advantages compared to previous WiFi versions. Thanks a lot, you convinced me to purchase a new WiFi6 router.
QUESTION: Could a wifi5 client take advantage of the OFDMA features of the wifi6 (pre)standard?
So, a lot of what he's talking about here is MU-MIMO, which is a feature of 802.11ac Wave2. Granted, it can't do the upload side that he talks about, but a 4x4 5Ghz 802.11ac Wave2 AP could connect 4 devices with their own 1x1 chain, or could have 2 phones each share a 2x2 chain with one other phone. Thus keeping congestion from becoming a problem.
Ubiquiti has the Unifi AP-XG which has MU-MIMO with 4 4x4 chains in it (effectively a 16x16 radio). Max recommended clients is 1000 per AP, theoretical max is 1500 clients per AP with an aggregate throughput of 4.2Gb/s.
A lot of what he's talking about is already here with 802.11ac Wave2
@@denton3737 This article seems to contradict your viewpoint - www.networkworld.com/article/3184077/tapping-the-brakes-on-802-11ac-wave-2.html
@@quadcom I question some of the validity of the article. Lots of devices support MU-MIMO. I know the samsung galaxy has since at least the S8, I would assume Apple has since roughly the same time. Now, AC devices from before 2016 most likely don't. This would include a lot of wireless cards in devices like laptop, desktop PCI cards, phones and tablets from before 2016 as well.
Essentially all mid range and up devices from 2017 and all AC devices from last year support MU-MIMO. It's just that a lot of those older devices haven't been replaced yet. A lot of people jumped on the AC wireless train and haven't need a reason to buy a new laptop as theirs from 2015 or 16 is working fine. I think that may be what they're trying to get at here.
As more devices are replaced while waiting for WiFi 6, wave2 devices will become more common and Wave2 will become more useful.
Don't get me wrong, Wifi 6 will be great, as it'll be an expansion on ac (think of the jump from N to AC) but I don't expect adoption rates to be as quick as AC was.
As far as your original question, which I think I actually glossed over entirely, the new standard will be backwards compatible with AC wave 1 and 2, but you will not get the other additional features of the new standard like simultaneous 2.4 and 5 ghz connections, or the tweaks and additions to MU-MIMO
@@quadcom I don't really see how the link you posted contradicts anything he said. They don't give any technical details, they basically say 802.11ac Wave2 isn't that beneficial to most organizations because the devices connecting to it don't support it. Kind of a silly argument against it imo. BUT the comment you replied to seems to be implying that this video is talking about MU-MIMO or that MU-MIMO and OFDMA are the same thing.. It's not. They're not. MU-MIMO and OFDMA are not the same thing. Sure, you could say that MU-MIMO tried to address the same issue that OFDMA does but not in the same way and not to the same extent.
Networking companies love ROM specifically not eeprom(electronically erasable programmable read only memory). so it gets flashed and is permanent. There are other kinds of ROM but the cheapest ROM is permanently written once at the factory and cant be changed.. Different company's use different technologies depending on social, in-house, and government demands. But I've tried to overwrite enough networking systems I feel comfortable saying most people are going to be throwing away their routers.
Is my current phone gonna work with that technology, or we'll have to wait for next gen phones?
Next gen, you need different hardware.

Well you shouldnt use public wifi anyway.
With the widespread adoption of TLS, for the vast majority of activities it's not unsafe to use public wifi, assuming there's not a secret global hacker ring selling TLS private keys of major websites.
Its perfectly ok if you have a VPN protection.. Verizon offers it automatically on their phones and connected devices such as tablets.. I personally use NORD anyway to protect better and also hide my location when its necessary as some sites seem to think they should block US users
You should use a VPN and several other things with pubWI
Hey Chuck, how does this compare to MIMO. Does this new standard reduce the need for MIMO?
I don't think so. Probably just increase the efficiency of MU-MIMO.
BOOM! I definitely COULD NOT have said it better myself. Appreciate you stopping by Robb!
Love your channel...watched a few videos earlier today and now I'm hopping around. Subscribed!
I have WiFi 6 with my unifi network at home. I have 4 of these new access points. Key thing to note is the network uplink is 2.5gb or 10gb because of the new abilities of 802.11ax .
I watched this at 1.25x speed and was tempted to go even higher.
This video felt way too long. At so many points I thought that you've already established the how and why of a topic but you went on an repeated it.
When you introduced the highway analogy it was clear fairly quick that you were about to explain that the new protocol is going to have multiple lanes and is going to allow side by side communication to multiple end devices. Maaan did you ride that horse dead. Was this video targeted to my mom?
what about security if modem gonna send a one big packet with information for lets say 5 devices so if you can intercept that one packet you will be able to get alot of more information, isnt that gonna be a issue ?
Perhaps I am not understanding it perfectly, but from what I gathered the bandwidth will be split into multiple independent virtual channels according to requirements, each channel will occupy a slightly different frequency range in the bandwidth, and communications with each access point will be independent of each other. So they should not be lumped together into one packet.
Thats what I was gonna ask. Thanks harold
surprised !!! I'm an IT Engineer and didn't no this , amazing ! WIFI 6 , thanks Man
Its so weird seeing him so chill not screaming at me right from the begining
I got 10base2 flashbacks watching this...
Hell I poured some whiskey out for Token Ring
You didn't mention MIMO (multiple input multiple output) on wifi 5
Indeed 2x2 4x4 MiMo
Exactly what I was thinking. He said all the way up to AC (WIFI 5), APs can only communicate with one device at a time. Isn't this incorrect since WIFI 5 (Wave 2) introduced 2x2, 3x3, and 4x4 MU-MIMO?
Exactly. Especially with MU-MIMO. I have had no issues with multiple users on public WiFi "5" even to the point where I can use a weak VoIP app on my tablet, through public WiFi, all the way to a cell phone and have minimal issues compared to 4G LTE. I hope AX is as great as Chuck describes, but I don't think the issue is a prevalent as walking through a mall. I mean if there is somewhere that you can probably get great public WiFi, it's probably at one of the dead malls throughout America, where you quite literally are not competing with any other devices for your WiFi signal. Chuck, you do a great job with a lot of these videos, but I don't believe you are being truthful with this one.
You are getting better and better as a teacher! Your video's are even MORE professional. What a great job. Thank you for all your work.
Hey Chuck, even with Wi-Fi AC you have now AP that do MIMO (3x3 or even 4x4) so they can talk to several devices at the same time.
As soon as hear him say Alexa, I cringed. Didn't you hear about the court cases of judges ordering Alexa recordings? Insane. Stay away like the plague
I've heard that too, but is it rumor or the truth. Granted, I heard about it from my teacher at Networking Administration school, so that is a reliable source.
@@DENicholsAutoBravado it's very true. We are buying home voice recorders for government agencies. The line needs to he drawn somewhere and currently no one is drawing it. Google the court case. That's frightening. I'm in the IT field, I could tell you more but I will he called a tin hat wearing alt right. :/
So, keep your home dumb out of fear for _potential, future_ danger? Hey, did you know they can tap into your phone calls and listen to everything you say? Time to get rid of all your phones.
This video reminds me of that Steve Jobs video presentation unveiling and asked everyone to turn their phones off because they were all connected to the wifi crashing his demonstration
This is a huge change in the wireless technology, it's been a while since we first time heard about it. But the standarization and industrialisation process just takes too much time, up untill now we still don't see it on the market yet.
Great Channel. I've been in the IT business over 30 years now, and I enjoy your content.
Thanks. Good info. If I may submit a user feedback: too long of a video for something that can be explained in 3-5 min
Unifi LR UAP + EDGEROUTER X = BEST ROutER to Buy.. . Set up is 2-4steps.
Just ordered my UDM Pro SE and the U6 LR. Pretty excited!
Gezz, 5 sounds like a supper fast Token ring....we just need a few more devices at 6. Oh ya, It's sad that most people don't change the namen of the 2nd wifi. 6.....so they can see the difference. Give it a 👍 you know this. I love this 😀
Absolutely love your attitude and excitement, it’s contagious! You’ve made topics that I’ve found daunting to be much more exciting, leading me to purchase a subscription to codecademy to get started with Python. Keep up the great work and keep on loving the Lord!
Please when you do these film bear in mind that you are talking to adults.
not everyone watching is an adult
This is an old video but I wished I watched it when it was uploaded. Excellent job breaking this stuff down comprehensively even for novice like me.
18:28 that scene made it very well understanding for me and surely for many more too.
Well, i do not hope the critical hospital equipment are using wifi, always use wired when this critical! Much more reliable
Wifi 6 is very sweet but not for critical equipment.
Hard to wheel equipment around with a bunch of cables hanging off. Batteries + WiFi solve that problem.
@@PongoXBongo that reason i could see it useful!
Just not stationary things.
Multiplexing... What a new a revolutionary idea.... What a joke... Takes these companies years to work out multiplexing is an option...
Fantastic explainaton on the new Wifi 6 standard as well as how wireless networks work in general. Very good!
This channel is totally successful
