Hi The answer is: it depends. Extended channels depend on the presence of TDWR radars in your environment (ex: if you are near an airport, there are lists of TDWR radars in the US). 40 Mhz channels depends on your clients: do you need more small cells in 20Mhz or can afford less available channels and go 40? Are there going to be more clients using 40 Mhz capacity or are they older clients which means your additional channel won’t be used by many VS the benefit of mitigating CCI...
Tell us more about your client devices and your environment. In the end, regardless of your APs’ capability it’s all about the client.

Should I enable the extended UNII-2 channels campus wide? 2. Should I enable 40Mhz channel width campus wide? In other words what are you doing on your campus and what is the "best practice? Our wireless infrastructure: 3 Cisco 5508s running 8.2.141.0 20 - 3800 APs 368 - 3700 APs 414 - 3600 APs 8 - 3500 APs 7 - 1810 APs 32 - 1142 APs Prime 3.1.0 Thanks for your input.
