What Freq/Channels do you use for your Mesh?

It seems like the sweet spot is Channel -1 (2.402GHz) from 2.392GHz to 2.412GHz

and Channel 14 (2.484GHz) from 2.474GHz to 2.494GHz

Thanks for your Reply.

"In the United States, the 13 cm band comprises frequencies in two segments stretching from 2.300 to 2.310 GHz, and from 2.390 to 2.450 GHz[2] The segment, 2.390 to 2.417 GHz, is domestically allocated amateur radio on a primary basis, while the remainder of the band is only available on a secondary basis.[1]" - http://en.wikipedia.org/wiki/13_centimeters

My understanding is as a license ham I am granted the right to use any device I want even if that device was released by the manufacturer to comply with part 15. As a license ham I am authorized to modify said device to make it comply with part 97. Channel "Negative 1" and Channel 14 both would fall under part 97.

With Channel "Negative 1" Falling into the frequency space that is reserved for Amateur radio as the primary user. This is why I see Channel Negative -1 Being the BEST? Channel for use in HSMM as the Primary users are Amateur Radio Operators and falls outside of part 15. Channel 14 is still desirable because it falls outside of part 15 although Amateur Radio Operators would be the secondary user.

First off, Wikipedia is the last place you want to turn to for quoting FCC rules and
reg's. Yes, I know it's "convenient" but not the definitive word.

Anyhow, if you'll read what I wrote I had no problem with the so-called channel -1
(then again, that would depend on your definition) but(!) you better check your
frequency tables for channel 14 which, according to the IEEE 802.11g standards,
clearly falls above the upper limit of the 13-cm allocation for amateurs (2450-MHz)
as well as the ISM band (2483.5-MHz) for the United States. Please explain how the
standard WiFi channel 14, available only in Japan and is centered on 2484-MHz, is
within the US Ham bands?  Even the low end is around 2472-MHz and still 22-MHz
ABOVE the highest frequency available in the 13-cm ham band.  If you have a different
definition of channel 14 please explain.

>The segment, 2.390 to 2.417 GHz, is domestically allocated amateur radio on a primary basis,

I don't think so since Part 97.303(e) which reads:

"Amateur stations receiving in the 33 cm band, the 2400–2450 MHz segment, the
5.725–5.875 GHz segment, the 1.2 cm band, the 2.5 mm band, or the 244–246 GHz
segment must accept interference from industrial, scientific, and medical (ISM) equipment."

Not sure how you can call that a primary allocation and your Wikipedia quote of 2400-2419 is not mentioned in the current Part 97.

If you feel you need to be absolutely sure that you're not interfering with ISM... the use of a spectrum analyser would be required to detect ANY signals in the area.   Then again, at the power levels we are generally working with, we'd be hard pressed to interfere with such equipment.
