Re: [WIRELESS-LAN] 2.4Ghz channel designations
None so far - other than the 3 academic departments who work on the system boards that currently only support 2.4GHz. For them, we have turned it on only for the APs in the relevant areas (9 APs out of 519), and only for their department-specific SSID. We made this change in conjunction with ditching the captive portal and whitelisted device RADIUS setup, and rolled out 802.1x. It was an ideal time to make the changes with new pushes toward improved security, and everyone out due to COVID-19. __ __ Fishel Erps, Sr. Network & Infrastructure Engineer School of Visual Arts 136 W 21st St., 8th Floor New York, NY, 10011 LL: 212-592-2416 C: 347-539-6380 E: fe...@sva.edu ___ On Wed, Aug 26, 2020 at 3:18 PM Peter P Morrissey < 0126530f918d-dmarc-requ...@listserv.educause.edu> wrote: > Impressive.

RE: [WIRELESS-LAN] [EXT] Re: [WIRELESS-LAN] 2.4Ghz channel designations
Rather than just making fun of the stupid suggestion, it’s probably worth explaining what makes it stupid. Back in the days of the 4-channel model all we cared about was throughput. Bandwidth was hard to come by, and maximizing it was beneficial. Figuring out which was better was easy. 4 channels gave you 33% more air time. If adding the fourth channel to your plan increased retries by less than 33%, you gained bandwidth. You could test it in your production network and easily measure the difference. I’ve tested it and it worked sometimes and didn’t work others. What determined the success was the AP layout and how they were channelized. If the AP density wasn’t too high (APs 80” to 100’ apart were common back then) and you carefully set your channels then 4 channels increased bandwidth. Switch to today. Is anybody manually choosing their channel plan? If not, is your automated radio management systems designed for this? I’m pretty sure the answer to both is “No.” Furthermore, we now have lots of real-time voice and video traffic on Wi-F that we didn’t have in the 11b days. (Yes there were wi-fi phones back then, but they sucked and you better not have many of them.) Today, retries affect service quality beyond just the airtime they use. Doing anything that’s likely to increase retries, even a little, is going to have a disproportionate impact on real-time service quality. Increasing bandwidth isn’t sufficient to make better Wi-Fi anymore.

Re: [WIRELESS-LAN] [EXT] Re: [WIRELESS-LAN] 2.4Ghz channel designations
I believe the basis for his idea is that, because 802.11 clients are far more sensitive to other 802.11 clients as opposed to noise, it's better to have those extra channels, whose overlapping channels would sound like noise to clients not on that specific channel. I am not saying I agree with this, haha. On Wed, Aug 26, 2020 at 11:44 AM Matt Wierzgac wrote: > I echo Seth’s statement.

Find a new consultant. Brady Ballstadt From: The EDUCAUSE Wireless Issues Community Group Listserv on behalf of John Rodkey Reply-To: The EDUCAUSE Wireless Issues Community Group Listserv Date: Wednesday, August 26, 2020 at 11:13 AM To: "WIRELESS-LAN@LISTSERV.EDUCAUSE.EDU" Subject: [WIRELESS-LAN] 2.4Ghz channel designations For many years I have consistently used channels 1, 6, and 11 as non-overlapping channels wherever 2.4Ghz is deployed. I have a consultant who is suggesting using all 11 channels in our high density dorm situations, arguing that signal interference will affect throughput less than the delays from protocols where the 3 channels are within hearing distance of each other. This doesn't make sense to me. If you in your situation have found using all 11 channels to be an effective solution vs the 3 channel non-overlapping approach, could you explain to me why you made that choice, and what your on-the-ground experience is with this configuration?
