Re: [AFMUG] UBNT frequency
Thank you guys. This is exactly as I suspected, but was never 100% sure. On Feb 6, 2015, at 3:07 PM, Josh Luthman j...@imaginenetworksllc.com wrote: The frequency you select is the center frequency.

Re: [AFMUG] UBNT frequency
It actually bleeds the same way any other wifi product does without any sort of specialized filtering (including airprism). Take the size of the channel * 1.5 and that will roughly give you the size of the channel plus the mask. A 20Mhz channel for instance will have a noticeable bleed that covers 30mhz total from side to side. 802.11n mask Josh Reynolds CIO, SPITwSPOTS j...@spitwspots.com www.spitwspots.com On 2/6/2015 1:07 PM, Josh Luthman wrote: The frequency you select is the center frequency.

Re: [AFMUG] UBNT frequency
I'm using the latest firmware version 5.5.10 and it doesn't show me that. The AC firmware running 7.1-rc shows me the full range though.

Re: [AFMUG] UBNT frequency
Is that in airOS 5.6? I remembered seeing it, but I was thinking it was on the AC radios.
