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
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.
Charles Cheevers
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
Matt
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
Amy Abatangle
@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
Stateless
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
Larry Lunetta
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.
Charles Cheevers
yep - differentiated curated services on a ton of bandwidth - with ODFMA at both their cores
Chris Preimesberger
Q2 coming up in a minute!
Chris Preimesberger
Sudden thought on Q1: Will we eventually have powerful enough WiFi to handle VR and AR on our home networks?
Charles Cheevers
Yes - Wi-Fi 6E - 66Gbps of potential
Zeus Kerravala
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
Stateless
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?
Matt
#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
Amy Abatangle
@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...
Matt
@CheeversCharles Agree that 6 GHz opens a new swath of usable spectrum to alleviate congestion and utilize faster connections.
Zeus Kerravala
A1. The "Software defining" of networks makes them programmable. Network engineers need to become software fluent. Work with #APIs, etc
Sivan Tehila
A1: I’m excited to see more visibility and granular policy management in new next-gen networking technologies. This is extremely valuable for organizations in light of our new #remotework reality.
#eweekchat #remoteworking
Zeus Kerravala
you can't secure or manage what you can;'t see!
Zeus Kerravala
A1. Also...#ArtificialIntelligence is ushering in the era of #AIOps into networking. legacy networks are manually intensive and slow to make changes. #AI is a game changer
Amy Abatangle
How real is #AIOps today? Asking for a friend.
Zeus Kerravala
There are elements of AI ops but it's not full AI Ops
Stateless
Hi this is Mike, big trends - Cloud connectivity demands are exploding; data science and networks are coming together, and the use of programmability in tech like P4.
Zeus Kerravala
A1. Next gen networking is certainly all about speed. #5G, #WiFI6, #400G,. We go faster and faster to support the unprecedented volumes of data
Zeus Kerravala
Yes, devices too! Lots of variety
Stateless
it's about speed +intelligence. The integration of advanced software into the device centric world of networking is going to open networks up so that tech like #AI can be applied.
Larry Lunetta
A1: Definitely seeing the move to the cloud and AI-powered network optimization as the focal points for customers. The cloud makes work from home and return to the office much more practical and AI dramatically simplifies operations.
Zeus Kerravala
Cloud changes the nature of business continuity
Charles Cheevers
Cloud is fundamental to all new services - Access Networks or Home Networks...
