CiscoLive! Over the Years – Wi-fi and CAE Hats!

Since 1998 the CiscoLive! occasions, previously Networkers, have been the community trade’s premiere occasion for training, product introductions, collaboration, and enjoyable.  Talking of enjoyable, I make a particular effort yearly to get a hat on the Buyer Appreciation Occasion (CAE) within the US.  The highest of my work-desk at residence displays years of CiscoLive! participation.

With CiscoLive! Amsterdam (February, 2023) in our rear view mirror and Las Vegas forward of us in June, I took time to replicate on how the occasion has advanced over time. Clearly, it has grown in attendee rely and requisite venue dimension. Content material is obtainable digitally and streamed – no extra 100+ web page printouts! The development of community programmability spawned our DevNet Zone. Social media has made the occasion extra related and private.

A quick historical past of wi-fi expertise

There’s been a LOT of change in expertise over time, presumably none extra so than in wi-fi networking.  The preliminary launch of the 802.11b wi-fi normal was in 1999. It reworked the trade with a shared medium sporting a whopping 11 Megabits per second on the two.4 Gigahertz spectrum. It’s taken with no consideration now in telephones, laptops, and tablets, however it was revolutionary to be related to the community with out wires!

To refresh our reminiscences, think about the historical past of wi-fi expertise –

Six generations later in 2019 Wi-Fi 6, often known as 802.11ax, was ratified. It affords many enhanced capabilities, however listed here are just a few notable mentions:

  • a possible most hyperlink fee of 9608 Mbps throughout a number of channels
  • Orthogonal Frequency Division A number of Entry (OFDMA) to subdivide channels into subcarriers and allow transmission to a number of purchasers concurrently
  • Overlapping Primary Service Units (OBSS) to enhance community congestion

Wi-fi over time at CiscoLive!

CiscoLive! San Diego had a Whisper Suite that 12 months to watch the rising expertise for these with early-release cell gadgets. The Wi-Fi 6 consumer ratios, compared to the general convention, had been very small at lower than 0.1% adoption.

Cisco Live Hats 3A number of months later at CiscoLive! Barcelona in January 2020 the Wi-Fi 6 ratio was nearly 6% of all wi-fi consumer associations.  Lastly, Wi-Fi 5 [or IEEE 802.11ac] was getting a challenger after years of being higher than 80% of the consumer associations!

Barcelona January 2020 was the final in-person occasion for some time till June 2022 with CiscoLive! Las Vegas. One thing curious to notice in reviewing the wi-fi statistics for our most up-to-date CiscoLive! Amsterdam February 2023 is {that a} world pandemic did NOT forestall individuals from upgrading their telephones, tablets, and laptops! We noticed Wi-Fi 6 (on 5 GHz spectrum) pull in 62% of the wi-fi consumer associations – a notable bounce in adoption fee!

Determine – A degree-in-time snapshot of the wi-fi consumer ratios from the CiscoLive NOC

Wi-Fi 6E, the newest normal was launched in 2020 and introduced a brand new 6 GHz spectrum.  There was a small deployment of Wi-Fi 6E succesful wi-fi entry factors within the Meet the Engineer/Skilled village. We began monitoring a brand new YANG mannequin metric from the Wi-fi LAN Controller’s telemetry associated to Wi-Fi 6E succesful purchasers. For these embracing community programmability and DevOps/SRE traits, the NETCONF RPC payload we used to ballot the WLC is seen beneath.

    <client-oper-data xmlns="http://cisco.com/ns/yang/Cisco-IOS-XE-wireless-client-oper">

The dot11-6ghz-cap metric signifies wi-fi purchasers that may use Wi-Fi 6E. For CiscoLive! Amsterdam 2023 we famous a most of 790 Wi-Fi 6E succesful wi-fi purchasers, out of whole occasion most of 13,225 purchasers.

So, how is that this fascinating?

If the entire variety of Wi-Fi 6E succesful consumer counts enhance dramatically, it means we’ve customers with newer cell gadgets able to having a greater wi-fi expertise. Are they? Or are they associating to a lesser operational normal due to a scarcity of Wi-Fi 6E infrastructure? This may occasionally present tangible metrics to assist drive a community refresh and take emotion and conjecture out of the decision-making course of.

In the event you’re excited about seeing 10 years of wi-fi community stats development…and CAE hats, take a look at this related video –

Increase what you are promoting insights and knowledge evaluation

Take a look at the wealthy telemetry and instrumentation that exists in your Cisco community — it could increase what you are promoting insights and knowledge evaluation!  Take a look at our product YANG fashions at Github.  For extra info of NETCONF, gRPC, and telemetry look to those studying assets:

See you at Cisco Dwell!

I hope to see you on the upcoming CiscoLive! June 4-8 in Las Vegas.  I’ll be within the NOC or the DevNet Zone. Listed below are my talking classes:

  • DEVNET-1279 Studying and Utilizing Kubernetes with a Cluster of Raspberry Pis – Half 1 of two
  • DEVNET-2279 Studying and Utilizing Kubernetes with a Cluster of Raspberry Pis – Half 2 of two
  • DEVNET-1534 Sensible Telemetry for the AppDev, DevOps and SRE
  • DEVNET-2200 Enhanced Automation of a Meraki-based Setting

Observe me on Twitter for the subsequent occasion – I’d be joyful to speak to you!



We’d love to listen to what you assume.
