we avoided the LBT problem by loading the APs with these channels 3660.00 MHz 3662.50 MHz 3665.00 MHz 3685.00 MHz 3687.50 MHz 3690.00 MHz
so channel "A" on the NE sector is 3660 (with 3662.5 secondary and 3665 tertiary) channel "A" on the NW sector is 3665 (with 3662.5 secondary and 3660 tertiary) so not quite ABA -sean On Fri, Nov 7, 2014 at 3:22 PM, Ken Hohhof via Af <[email protected]> wrote: > > I am more worried about the 20 MHz channels than the 6 sectors. > > I don't know how you do ABABAB with 20 MHz channels and LBT. I assume you are planning to let A be in lower 25 and B in upper 25, you will have to use LBT on both, and I guess you use the trick of having the LBT secondary channels heavily overlap the primary channel. > > Also you lose the advantage of not competing with every nimrod with an unregistered Ubiquiti 3.65 radio. I find the upper 25 is very clean and the lower 25 not so clean. There's a lot more people who can afford $125 for a radio than $2500. > > FCC was looking at opening up another 100 MHz of spectrum, weren't they? That would change things a bunch. Like you could do ABCDABCD using 90 degree sectors and 45 degree spacing, thus filling in the gaps between the cloverleaves to get more of a circular coverage rather than a square/diamond. > > > -----Original Message----- From: George Skorup (Cyber Broadcasting) via Af > Sent: Friday, November 07, 2014 4:05 PM > To: [email protected] > Subject: Re: [AFMUG] Canopy 3.65 Cluster > > > I predict sucky SNRs. > > On 11/7/2014 4:00 PM, Matt via Af wrote: >> >> Anyone know if its possible to do a 6 AP cluster of 3.65 AP's with >> 20Mhz channels doing ABABAB for increased capacity? > > >
