Re: [WIRELESS-LAN] Are You Ready for WiFi6E

[James Helzerman]

I like the idea of a 6ghz radio and all that sweet sweet frequency it opens
up but I'm torn between that and seeing a cbrs radio in the next generation
of access point (in the next year).  I can make what I have work right now
but the DAS cellular world with a vendor neutral system plus the potential
for our own e-sim lte is something we have been longing for.  Of course
that has many hurdles as well..

RE: Are You Ready for WiFi6E

[Glinsky, Eric]

I asked Cisco about what 6 GHz means for their APs and their response is:

"6Hz will require new hardware for both APs and clients.  We expect major chip 
makers to have their products ready by the end of 2020. By early 2021 we expect 
to see a few 6Hz capable consumer access points and high-end client devices 
like smartphones, tablets and laptops followed by enterprise-grade access 
points later in 2021."

If that's the case, I imagine we won't be deploying 6 GHz APs until at least 
the summer or fall of 2022 and maybe even longer before we can even start using 
6 GHz channels while client devices catch up.

As for power, we've been deploying UPOE for a few years, but most APs are 
hooked up to PoE+, so hopefully that's enough for full WiFi capabilities at 
least. Heck, we're still trying to get away from 100M/15.4W switches in 20 or 
so buildings. We don't have mGig anywhere yet, but I don't think we'll be 
seeing more than 1Gbps needed through an AP for a while. I'd be interested if 
anyone does.

I'm with you on the code problems, Lee. I believe no new product should be on 
our network until it's been receiving software updates for at least a year. We 
got burned by Cisco 2800s in 2016, but they're great APs now. Would we have 
been better off with another year's worth of 2700s in use today and avoiding 
the first year of 2800 issues? Technically probably not, but it's a matter of 
community perspective also.

Hi Hector,

More channels in and of itself is fantastic, even if we don't bond them up into 
huge wide ones. As for APs being hurried out, I'm more interested in how 
clients will roll out. I don't have a lot of faith in certain WLAN vendors 
getting 6 GHz right for a while, given track records to date of shotgunning 
alpha quality code onto the market. Also halfway expect the license-happy 
idiocy that's becoming pervasive to apply to new hardware and what you are 
"allowed" to do in 6 GHz, despite it being unlicensed by the FCC.

Now that the FCC has approved the 6GHz band, I wonder what others are doing in 
terms of planning. There is a lot to think about and unlike prior 
announcements, this one really is a game changer. Here are some thoughts:

*Vendors should be rushing to make APs and make them available possibly this 
year.
*The assumption is that the new radios will be tri radios. I'm sure vendors 
will get creative.
*More radios chains and more features (BLE, USB, Zigbee) mean more power needs.
*Faster more efficient technology means faster speeds required: 2.5G/5G.
*Will your existing infrastructure be capable to handle the new technology? 
Today, most likely not.
*If in the middle of a lifecycle, do you continue or do you wait?

For those that are super excited, here are some last things to think about:

Higher modulations require higher levels of SNR. Higher frequencies have 
shorter wavelengths and more trouble getting through objects. Bonding channels 
raises your noise floor and also requires higher receiver sensitivity. There 
are a ton of other things to consider. What say you?

Not trying to be a wise-guy. In my mind, based on everything else we're seeing, 
I presume that licensing it for profit is a given. I hope I'm wrong though.

Now that the FCC has approved the 6GHz band, I wonder what others are doing in 
terms of planning. There is a lot to think about and unlike prior

*Vendors should be rushing to make APs and make them available possibly this

*The assumption is that the new radios will be tri radios. I'm sure vendors

*More radios chains and more features (BLE, USB, Zigbee) mean more power needs.

The first step is tools. If we can't survey and troubleshoot then we will be 
blindly jumping into things.

I want to understand what impact AFC will have in our area as well. Plenty of 
time for planning that's for sure.
