Just make sure that you meet the bit rate and payload requirements of 101.141. If you can't do that, getting the "widest channel you can" would be problematic. ________________________________ From: Af <af-boun...@afmug.com> on behalf of Mathew Howard <mhoward...@gmail.com> Sent: Wednesday, August 16, 2017 10:39:20 AM To: af Subject: Re: [AFMUG] AF-11x
Seems pointless not to ask for the widest channel you can get. Unless you're absolutely sure you're never going to need more bandwidth, then I guess you could be nice and try to leave some more spectrum open, but if there's even a tiny chance you're going to ever need more capacity, I'd just go for the widest you can get.

It appears that almost all of them will work with a 2 foot dish at up to perhaps 10 miles. So the question will be what to ask for on the license. I presume I should ask for the widest channel I can get. From: Faisal Imtiaz Sent: Tuesday, August 15, 2017 7:41 PM To: af@afmug.com Subject: Re: [AFMUG] AF-11x Suggestion.. Look at the Users guide from ubnt.com<http://ubnt.com> website for the AF11X. AF11x can work on a number of configurations.. Channels width of 5mhz to 56(80mhz)mhz SISO horizontal or vertical only channels MIMO both polarities (horizontal + Vertical), this configuration needs the additional diplexer.

If licensing is the same, why not. From: Jon Langeler Sent: Tuesday, August 15, 2017 4:11 PM To: af@afmug.com Subject: Re: [AFMUG] AF-11x I like using both polarities to maximize Rx sensitivity. Coordination is the same cost. Duplexers are also not that much more. Jon Langeler Michwave Technologies, Inc.

I'm not sure there's much point in going in narrower than that. Actually, doing SISO at a 56mhz channel might make more sense, that should get around 275mbps at 256qam (and a bit more if the link will do 1024qam, obviously), but then you'd only need a one polarity, so it may save a bit on coordination, and you wouldn't need to buy the extra duplexers.

I only need about 250 Mbps so lower order modulation may be desirable and perhaps narrower channels too.

The above configuration is just an example. On Tue, Aug 15, 2017 at 10:53 AM, Jeremy <jeremysmi...@gmail.com> wrote: They are like that, but 3x bigger. On top, the lid comes off and the duplexers go beneath the cover. If your link is 'High' then you will want 'High' duplexers for both sides of the link (x4 total - two extra to purchase) - they will go in a configuration like 1-3-3-1 on one side and 3-1-1-3 on the other side.

You do need to figure out what frequencies you're going to be using before you buy the radios, since there are two different duplexers, depending on which half of the band you're in. You need one frequency pair on both polarities (for MIMO).

I guess you have to have two pairs of frequencies? Or at the very least, both polarizations on the same frequency? Trying to collect some budgetary estimates on what my project is going to cost.
