Proprietary Radio Channels

[physical]

I understand that the out of the box solution doesn't really provide for this, but I was wondering...

I've been hacking around a few LS2s and PS2s, and I'm trying to get them to work on a frequency that exists outside of norms. The company I'm working for has a license to the bands they would like me to broadcast in (EBS Band)... The problem is, of the 4 5mhz bands they have, only one of them falls on a frequency that will work with the chip's standard frequency list...

The other three frequencies land in the middle of two frequencies, and if they hope to deploy them using those frequencies they have license for, they're going to have to stay inside their range.

I've been hacking around plenty, reviewed most of the source for madwifi, ath5k, etc. Stared at EEPROM dumps from various units for more than I'd like.

I don't mind doing the work, and I'm not asking for a solution (unless you already have one), but they're your radios and you know em better than me... I've never actually seen anything that resembles Atheros documentation on these things... I'm just hoping for a bit of brainstorm to help the process out...

From what I understand...
The frequency data is stored in the flash EEPROM, right? Or is that sort of thing hidden behind the binary HAL? If its in the HAL... there isn't really much a person could do, cept hope for ath5k to mature enough to actually be useful as a base station...
If its in the EEPROM, would it just be a matter of figuring out where a frequency value sits, change it to one that I like and fix the checksum? Thus far, I haven't found anything outlining the contents of the flash EEPROM beyond the first 124 bytes

So, tl;dr, what do you think the best way to convince the radio to broadcast a few mhz diff, or do you think it's impossible without excessive work

I noticed that in my PowerStation5 - Linksetup/RateMode: half (10MHz) /quarter (5MHz) when you go from 20 MHz channels to 5 MHz channels - the web interface still only shows 20MHz channel increments in the pull down selection - I would love to see a future version show channel selections in half or quarter MHz increments when you select that size.

Now to confirm - I plugged in a litestation2 and see 2 that this DOES then show 5MHz increments. Hmm - maybe a firmware issue? Please advise...

The dropdown is showing Standard issue channels.

The 2.4g range has overlapping channels. Even when using a 20mhz wide band, you would still be given the 5mhz increments for frequencies.

In the 5g range, The channels are arranged to not be overlapping. Not actually sure if the FCC (or whatever governing body you might fall under) would allow a half-band broadcast offset from the baseline...

Your concern isn't a firmware issue or bug. Its a physical limitation of the Radio chip. Somewhere out there, the Radio has a list of frequencies that it can use. These channels are dictated by your governing body.

The fun part about my question is, how hard would it be to tweak a frequency by only about 2mhz?

Standard issue consumers using ordinary Wi-Fi builds would never need to use anything outside of the normal channels and modes presented in the setup. Tweaking your 5g frequency by 5mhz would make it impossible for users to find your network. Their radios are not designed to scan anything other than the normal list.
The only way to deploy a wireless network on a non-standard channel would be to provide tweaked radios for the end user (which is our intention). Also, you'd prolly need your governing body to sign off on your plan.
