Wireless Channel Width Question - 20 vs 40 vs 80Mhz
Posted on 2016-09-20
Greetings, everyone. We have a Meraki deployment with 10 APs and about 80 users in a 25,000 sf space.
Our APs are MR32 - 802.11ac They are set up to connect clients capable of 5Ghz to that band, then move them to 2.4Ghz if they have older wireless NICs. Most clients can work at 5Ghz with 802.11n We have very few 802.11ac clients yet.
I understand that in "high-density" areas, lower channel width is desirable. But I'm not sure what constitutes "high-density". Is 80 clients in 25,000 sf considered "high-density" ? I had the APs set at 80Mhz for the 5Ghz band, but lowered it to 40Mhz. Is that recommended or is 20Mhz recommended ? If I understand correctly, I'm sacrificing wireless speed by using lower channel width, right ? We're running out of physical ports and there is a lot of mobility around our office (people working all over the place), so wireless speed (at least to access our on-prem file server) is important.
Suggestions ? Does my config sound about right ?
