Since 1998 the CiscoLive! occasions, previously Networkers, have been the community trade’s premiere occasion for schooling, 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 house 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. 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 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 with no consideration now in telephones, laptops, and tablets, nevertheless it 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, often known as 802.11ax, was ratified. It gives many enhanced capabilities, however listed below are a couple of notable mentions:
- a possible most hyperlink price 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 shoppers concurrently
- Overlapping Fundamental Service Units (OBSS) to enhance community congestion
Wi-fi over time at CiscoLive!
CiscoLive! San Diego had a Whisper Suite that yr to look at the rising expertise for these with early-release cellular units. The Wi-Fi 6 shopper ratios, compared to the general convention, have been very small at lower than 0.1% adoption.
A number of months later at CiscoLive! Barcelona in January 2020 the Wi-Fi 6 ratio was nearly 6% of all wi-fi shopper associations. Lastly, Wi-Fi 5 [or IEEE 802.11ac] was getting a challenger after years of being larger 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. One thing curious to notice in reviewing the wi-fi statistics for our most up-to-date CiscoLive! Amsterdam February 2023 is {that a} international 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 leap in adoption price!
Determine – A degree-in-time snapshot of the wi-fi shopper ratios from the CiscoLive NOC
Wi-Fi 6E, the most recent 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/Professional village. We began monitoring a brand new YANG mannequin metric from the Wi-fi LAN Controller’s telemetry associated to Wi-Fi 6E succesful shoppers. For these embracing community programmability and DevOps/SRE traits, the NETCONF RPC payload we used to ballot the WLC is seen under.
<filter xmlns="urn:ietf:params:xml:ns:netconf:base:1.0">

</filter>
The dot11-6ghz-cap metric signifies wi-fi shoppers that may use Wi-Fi 6E. For CiscoLive! Amsterdam 2023 we famous a most of 790 Wi-Fi 6E succesful wi-fi shoppers, out of complete occasion most of 13,225 shoppers.
So, how is that this attention-grabbing?
If the overall variety of Wi-Fi 6E succesful shopper counts improve dramatically, it means we now have customers with newer cellular units 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 will likely present tangible metrics to assist drive a community refresh and take emotion and conjecture out of the decision-making course of.
If you happen to’re thinking about seeing 10 years of wi-fi community stats development…and CAE hats, try this related video –
Increase what you are promoting insights and knowledge evaluation
Try the wealthy telemetry and instrumentation that exists in your Cisco community — it might probably increase what you are promoting insights and knowledge evaluation! Try our product YANG fashions at Github. For extra info of NETCONF, gRPC, and telemetry look to those studying sources:
See you at Cisco Reside!
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 here are my talking periods:
- 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 Atmosphere
