  • We have a new wireless standard... 802.11ax or WIFI 6...and it's AMAZING!! It's not just faster, it changes the game! With features like OFDMA, TwT, and BSS Coloring, wifi will never be the same.

    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

      @@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.

      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)

      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.

      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.

      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

      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

    • @EsotericArctos
      @EsotericArctos Před 5 lety +1

      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.

    • @bijubalan7819
      @bijubalan7819 Před 5 lety +2

      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.

    • @needsomehike

      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?

      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

      @@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

    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.
