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


Since 1998 the CiscoLive! occasions, previously Networkers, have been the community business’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 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 mirror on how the occasion has developed over time. Clearly, it has grown in attendee rely and requisite venue measurement. 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 short historical past of wi-fi know-how

There’s been a LOT of change in know-how over time, probably none extra so than in wi-fi networking.  The preliminary launch of the 802.11b wi-fi customary was in 1999. It reworked the business 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, but it surely was revolutionary to be related to the community with out wires!

To refresh our recollections, contemplate the historical past of wi-fi know-how –

Six generations later in 2019 Wi-Fi 6, also referred to as 802.11ax, was ratified. It gives 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 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 know-how 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.

Cisco Live Hats 3A number of months later at CiscoLive! Barcelona in January 2020 the Wi-Fi 6 ratio was virtually 6% of all wi-fi shopper associations.  Lastly, Wi-Fi 5 [or IEEE 802.11ac] was getting a challenger after years of being better 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} 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 shopper associations – a notable bounce in adoption fee!

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

Wi-Fi 6E, the most recent customary 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 purchasers. For these embracing community programmability and DevOps/SRE traits, the NETCONF RPC payload we used to ballot the WLC is seen beneath.

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 whole variety of Wi-Fi 6E succesful shopper counts improve dramatically, it means we’ve customers with newer cellular units able to having a greater wi-fi expertise. Are they? Or are they associating to a lesser operational customary due to a scarcity of Wi-Fi 6E infrastructure? This may increasingly present tangible metrics to assist drive a community refresh and take emotion and conjecture out of the decision-making course of.
