RE: Are You Ready for WiFi6E
We have a very long / continuous planning horizon: it's not only the cabling to the AP that needs a boost, but the installation of 220V circuits to the PoE switches to support UPOE/POE+/4PPoE. (because a regular 120V outlet isn't going to cut it). I had to ask for electrical improvements last October for installation sometime after July of this year and there is no guarantee I'll get what I asked for or when it will get installed. In recently constructed buildings the cabling will support power and M-gig networking these AP might need (but those buildings will be at the end of the cycle as I'd like to be at least at 802.11ac everywhere). In our phased lifecycle plan we're including replacing the AP cabling for support this (but not the wall-port cabling as we see more of a move to wireless devices). Finally, given the expected fiscal impact of Covid-19 on the institution I do not expect to see any move to this on our campus in the next ~18 months - maybe after July 2021 (end of the next fiscal year) Richard Letts Director, Networking and Telecommunications ITaP Infrastructure Services Purdue University rle...@purdue.edu<mailto:rle...@purdue.edu> O: 765-496-1663 C: 206-790-5837 From: The EDUCAUSE Wireless Issues Community Group Listserv On Behalf Of Rios, Hector J Sent: Friday, April 24, 2020 10:16 AM To: WIRELESS-LAN@LISTSERV.EDUCAUSE.EDU Subject: [WIRELESS-LAN] Are You Ready for WiFi6E Now that the FCC has approved the 6GHz band, I wonder what others are doing in terms of planning.

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