Q3: What is intent-based networking and what are its business advantages? Is your company using this?
Background story by Zeus: https://www.eweek.com/networking/understanding-the...

Understanding the Key Trend of Intent-Based Networking
TREND ANALYSIS: During the next several years, the IT industry will see a rise IBN vendors; some that address part of the solution and others that are end to end.

A3: I think that intent-based networking is an evolution of SD-WAN, but sounds like marketecture more than anything else right now; the paradigm makes sense, but it's early. Still haven't seen the full potential of SD-WAN outside the enterprise.

Tony Cai - Nerdio

I had to read the article as I was not familiar with the term, so its basically AI networking governed by the IT administrator.

Chris Preimesberger

Marketechture! Love it

A3. Intent based networking is the mixture of data science and data communications. It has huge potential as tech is produced that allows networks to become 'aware' of the data that they are carrying. There's a lot of promise in this tech.

The network needs to be more programmable before we see true 'intent-based' networking apps.

A2: The seamless integration of Wi Fi and 5G is already happening with services such as Passpoint for easy roaming between the two. As telcos deliver new on prem services to their enterprise customers, cloud-managed orchestration will further enable the wi fi on ramp to 5G.

good point. Many view #5G and #Wifi6 as competing technology but the two are actually complementary

@zkerravala A2: Agree. It's more about better performance and access everywhere, though not sure it will be seamless to start.

This is Mike Anderson again... great point Larry, 5G to get the data into my building, WiFi 6 to get it to my desktop.

Tony Cai - Nerdio

How about Tesla StarLink? What does everyone feel about that technology and mass adoption as an alternate ISP?

Charles Cheevers

@zkerravala It will be interesting to see how the 1.2GHz of spectrum us used for Wi-Fi 6E and 5G NR-U.... For Home applications its still the most effective and consumer friendly to use Wi-Fi and offload cellular to Wi-Fi.... will continue but the 5G NR-U devices will leak in

A2: Yes, I think it will become a backbone #network due to faster #WiFi network speed and lower latency. It could potentially replace fiber networks as the ideal frontrunner for internet network in the office. Those are my thoughts. #eweekchat

A2: I do think #WIfi6 and #5G will allow wireless to become the primary network instead of augmentation to the wired network.

Q2: Might WiFi6 + 5G connectivity become the next backbone-type network? Why or why not? Here's some background: https://www.eweek.com/networking/why-wifi-6-might-...

Why WiFi 6 Might Become the Next Backbone Network
eWEEK NETWORKING ANALYSIS: When WiFi 6 adopts millimeter wave technologies, the speed limits are off, and your new backbone network might never see fiber again.

Not Wi-Fi 6 but Wi-Fi 6E

Chris Preimesberger

Can you define the difference there,please

Charles Cheevers

Wi-Fi 6E brings the 1.2GHz of spectrum to build a backbone at 4x4 (4.7Gbps) and 8x8 at almost 10Gbps

A2: In many cases, networks will evolve to this type of architecture. There are areas where this makes absolute sense, and areas where transition will be slower.

Charles Cheevers

What is really going to be the paradigm shift for wireless home backbone is Wi-Fi 7 or 802.11be - where we create a 320Mhz QAM4096 capable backbone to put 10Gbps over the home...... and can then look even at having inroom wireless architectures at 4Gbps themselves

@CambiumMatt Agree, Matt. This isn't going to happen all at once when capital costs are involved.

Charles Cheevers

Wi-Fi 6 is the new MAC standard for Wi-Fi..which has lots of improvements.... but cannot be realized in a mixed Wi-Fi 5 and 6 environment and is locked into 2.4GHz and 5GHz

Chris Preimesberger

Ah.Thankya!

WiFi6 + 5G will help solve access. I see them more in the last mile role. That said, they have the potential to transform edge connectivity and are needed as we will continue to see more digitalization.

Charles Cheevers

Wi-Fi 6E is new spectrum - 1.2GHz of it (4x more than today) that ONLY allows Wi-Fi 6 devices enter it - thus realizing the full 4x potential of Wi-Fi 6 immediately

Charles Cheevers

THink of a special 66Gbps HOV lane for Wi-Fi 6E - 6GHz capable devices and all the other 5GHz only capable devices in the commute lanes

A1: Absolutely. With the additional bandwidth and performance of Wi Fi 6 and 6E along with techniques such as guaranteed QOS for specific applications and users (think network slicing for Wi Fi), apps like VR/AR are very practical.

yep - differentiated curated services on a ton of bandwidth - with ODFMA at both their cores

Q2 coming up in a minute!

Chris Preimesberger6

Sudden thought on Q1: Will we eventually have powerful enough WiFi to handle VR and AR on our home networks?

[+] Show Hidden Comments

Charles Cheevers

Yes - Wi-Fi 6E - 66Gbps of potential

Chris Preimesberger

cool!

Both #5G and #WiFi6 will bring wireless speeds up to par with wired... Wired versus wireless is no longer a choice... #VR and #AR will run fine over WiFi

Charles Cheevers

Scope to even do HDMI over 6E but will still be lightly compressed to fit into 4x4 - 4.7Gbps initially

Absolutely. One thing that the network has been always been able to do is go faster! But will the WAN infrastructure get the RIGHT data to your doorstep?

#wifi6 can certainly handle VR applications

Charles Cheevers

@zkerravala VR at 8K or even 4Kp60/120 which is what we need does not run well over Wi-Fi 5 today.... Sure there are some VR Googles and Phones in boxes - but thats not where VR needs to be...needs either Wi-Fi 6E or 60GHz to really have the latency and b/w required for 10ms

@stateless_inc @editingwhiz That's the real question, along with the realistic demand for consumer VR/AR apps. It hasn't really materialized yet.

Tony Cai - Nerdio

@CheeversCharles any health concerns around so many radio signals through the air? I always wondered how the SAR scale on mobile phones correlate with wifi AP's in homes and businesses.

Charles Cheevers

We are making sure that the power levels are appropriate for home use...so should be good... In fact we define the 6E level as Low Power Indoor mode - so that it wont interfere with Fixed Links using 6GHz today.. We have also specified a Very Low Power 25mW mode

Charles Cheevers

@CambiumMatt Not if your in an MDU with 5GHz congestion - thats what the new spectrum at 6GHz is for... You can almost have your own channel per apparment ... with 7 160MHz channels and 14 x 80MHz...

@CheeversCharles Agree that 6 GHz opens a new swath of usable spectrum to alleviate congestion and utilize faster connections.

A1. The "Software defining" of networks makes them programmable. Network engineers need to become software fluent. Work with #APIs, etc
