Be aware, the minimum rate question is far less straight-forward than the 11b rates question. The latter is really an issue of client device compatibility - something we can expect to be similar across our market sector. In addition client device compatibility, minimum data rate depends upon signal strength, noise level, and channel width.
That said, if you use 40MHz channels and maintain an SNR >= 20dB (I assume that's most of us these days), you can definitely disable MCS 1 & 2 - probably even MCS 3.

It sound like a lot of people have already disabled the 802.11b data rates. That being said....what minimum rate is everyone using? We just changed ours last week from a minimum of 1Mbps to 54Mbps. So far we have not heard of any issues. Does anyone know what if any problems could arise from this being set to 54Mbps? Is there a sweet spot in between that is better?

We have had the b rates disabled for 2 months short of 5 years. Not a single complaint that I am aware of. -jcw John Watters The University of Alabama Office of Information Technology 205-348-3992 -----Original Message----- From: The EDUCAUSE Wireless Issues Constituent Group Listserv [mailto:[email protected]] On Behalf Of Todd M. Hall Sent: Monday, June 20, 2016 10:50 AM To: [email protected] Subject: [WIRELESS-LAN] 802.11b data rates disabled? Do you have all of the 802.11b data rates disabled? If so, how long have they been disabled? Did you have many complaints when you disabled them? Were there any particular devices that could not connect as a result? I'm hoping this information will help us move towards disabling these old rates. Thank you for your feedback. -- Todd M.
