back to article Switchzilla rolls out Wi-Fi 6 kit: New access points, switch for a standard that hasn't officially arrived

Networking overlord Cisco has unveiled Wi-Fi access points and core switches supporting the latest wireless networking standard, the 802.11ax – otherwise known as Wi-Fi 6. Plenty of its competitors have already launched their own takes on the standard, including HPE's Aruba, Huawei, Netgear and TP-Link – even though the …

    Nomenclature

    I'm sure absolutely no one will confuse 5G and WiFi 6.

      Re: Nomenclature

      I've been hearing people claim their mobe is 5G for some time now, just because it has 5GHz Wi-Fi.

    Wifi 6, finally branding that the consumer will understand.

      LET N_starting_point := 6

      Hans 1 offered, "Wifi 6, finally branding that the consumer will understand."

      At least they've achieved MNP (meaningless numerical parity) with "DECT 6.0".

    They should have just called it "Dave".

    Anyway, as for this: 'Wi-Fi 6 promises lower latency – as low as 10 ms, versus 30ms on Wi-Fi 5"

    Huh? I average 8 or 9 ms router-ping on my "wifi 5" devices. I'm sure the 2.4Ggz devices are similar.

      It’s worst case latency on congested networks.

      It’s a large venue feature rather than something for most homes to allow multiple clients to communicate at once and to schedule clients time to communicate with APs to reduce congestion with high client counts.

        Re: Dave

        In large venues with WIFI 5 we regularly see latency over 200ms (though mainly only for some Apple devices). 30ms average when busy is something to aim for...

        Ahhh ok, thanks for the clarification.

        Cheers!

    But the question remains: Does it come with the standard NSA back door?

      The backdoor is not required by the standard, but is allowed in the implementation.

    Active scanning of DFS channels?

    I think current routers scan the DFS channels between the 2.4 and 5Ghz channels when turned on and if they detect a radar signal in them then won’t rescan them until the router is switched off and on again (apparently due to a lack of a second radio and enough cou processing power).

      Re: Active scanning of DFS channels?

      This behaviour will be AP dependent.

      The lower end AP's only have client facing rados unless set as monitoring AP's, so exhibit the behaviour you note, although I believe that may also be a requirement in some regulatory zones.

      In the enterprise class AP's (i.e. anything using CleanAir - additional radios to scan for interference), they will scan channel availability based on controller settings - either manual/on-demand/scheduled.

      Some DFS channels you may want this behaviour, others, like those used for weather radar that scan regularly, you really want to avoid entirely as they will cause client problems.

    The Cisco 9600 (chassis, supervisor card, line card) is based around the Sup10T that was developed for the Catalyst 6K.

    Target market for this platform are for "high density 100 Gbps" (up to 24 ports x 100 Gbps per slot) with Sup1.

    The Cisco Catalyst (yes, the APs are called "Catalyst") 9115ax and 9117ax are based around "merchant silicone" chips. These APs are "equivalent" to an 1800-series AP and target market is aimed squarely on the "price conscious" buyers.

    Please take note the different power draw: 15.4w (eco mode), 30.0w (full power) and 32.0w (USB support).

    1. LewisRage

      Sorry... Cisco have reused the model name Catalyst for their WAPs.

      I just find this stuff astonishing, like there aren't enough words to use to give a new thing a new name?

      I can see it now "Dave bring a Cisco Catalyst in the van with you, we need to increase capacity at site"

      "No problems Steve, I've got one to hand, see you in an hour"

      ...

      "Steve you spanner, you've brought a fucking switch/access point [delete as necessary] when I clearly meant you to bring an access point/switch [delete as appropriate]"
