Since 1998 the CiscoLive! occasions, previously Networkers, have been the community trade’s premiere occasion for schooling, product introductions, collaboration, and enjoyable. Speaking of enjoyable, I make a particular effort yearly to get a hat on the Customer Appreciation Event (CAE) within the US. The prime of my work-desk at dwelling 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 developed over time. Obviously, it has grown in attendee rely and requisite venue dimension. Content 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 short historical past of wi-fi expertise
There’s been a LOT of change in expertise over time, probably none extra so than in wi-fi networking. The preliminary launch of the 802.11b wi-fi commonplace was in 1999. It remodeled the trade with a shared medium sporting a whopping 11 Megabits per second on the two.4 Gigahertz spectrum. It’s taken as a right now in telephones, laptops, and tablets, but it surely was revolutionary to be related to the community with out wires!
To refresh our recollections, take into account the historical past of wi-fi expertise –
Six generations later in 2019 Wi-Fi 6, also referred to as 802.11ax, was ratified. It gives many enhanced capabilities, however listed below are a couple of notable mentions:
- a possible most hyperlink fee of 9608 Mbps throughout a number of channels
- Orthogonal Frequency Division Multiple Access (OFDMA) to subdivide channels into subcarriers and allow transmission to a number of purchasers concurrently
- Overlapping Basic Service Sets (OBSS) to enhance community congestion
Wireless over time at CiscoLive!
CiscoLive! San Diego had a Whisper Suite that yr to watch the rising expertise for these with early-release cell gadgets. The Wi-Fi 6 shopper ratios, compared to the general convention, had been very small at lower than 0.1% adoption.
Several months later at CiscoLive! Barcelona in January 2020 the Wi-Fi 6 ratio was virtually 6% of all wi-fi shopper associations. Finally, Wi-Fi 5 [or IEEE 802.11ac] was getting a challenger after years of being higher than 80% of the shopper associations!
Barcelona January 2020 was the final in-person occasion for some time till June 2022 with CiscoLive! Las Vegas. Something 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 stop individuals from upgrading their telephones, tablets, and laptops! We noticed Wi-Fi 6 (on 5 GHz spectrum) pull in 62% of the wi-fi shopper associations – a notable bounce in adoption fee!
Figure – Some extent-in-time snapshot of the wi-fi shopper ratios from the CiscoLive NOC
Wi-Fi 6E, the newest commonplace 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/Expert village. We began monitoring a brand new YANG mannequin metric from the Wireless 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 under.

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 attention-grabbing?
If the full variety of Wi-Fi 6E succesful shopper counts enhance dramatically, it means we now have customers with newer cell gadgets able to having a greater wi-fi expertise. Are they? Or are they associating to a lesser operational commonplace due to a scarcity of Wi-Fi 6E infrastructure? This might present tangible metrics to assist drive a community refresh and take emotion and conjecture out of the decision-making course of.

See you at Cisco Live!
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. Here are my talking periods:
- DEVNET-1279 Learning and Using Kubernetes with a Cluster of Raspberry Pis – Part 1 of two
- DEVNET-2279 Learning and Using Kubernetes with a Cluster of Raspberry Pis – Part 2 of two
- DEVNET-1534 Practical Telemetry for the AppDev, DevOps and SRE
- DEVNET-2200 Enhanced Automation of a Meraki-based Environment
