Some noted that the ac standard provides for dynamic >>> switching back and forth to 20 MHz, so interference is less of an issue. But, those respondents didn't mention if they were using only the U-NII-1 and U-NII-3 bands, or if they are also using the bands that require DFS, U-NII-2 and/or -2e . Is there any consensus or best practice on this? Is anyone using -2 and -2e, or just staying with four non-overlapping 40 MHz 5 GHz channels? Are most current clients able to connect to the DFS channels? Aruba's "RF and Roaming Optimization for Aruba 802.11ac Networks" doc ( http://community.arubanetworks.com/t5/Validated-Reference-Design/RF-and-Roaming-Optimization-for-Aruba-802-11ac-Networks/ta-p/227716 ) says that: "Majority of voice specific devices do not scan many channels before roaming as they have active voice calls. For such devices, do not use U-NII-2 and U-NII-2e channels." and "Roaming test should be performed using different types of clients expected on the WLAN, to see their behavior on DFS channels." So, that sounds like a "no" vote on DFS, though we don't have wifi VoIP phones. Does any one have field experience and recommendations? Any guesses if DFS channels will ever be useable with a student BYO client base?
