It appears that some cisco equipment, at least, uses fractional center frequencies for 5Mhz channels.

Has anyone attempted to support this with ath9k?

Thanks,
Ben

I was not aware that anything supported 5Mhz other than ath9k and ath5k. Thx. Can you identify what cisco gear supports this?

I have long advocated that meshy networks in increasingly dense areas use narrower channels.

was one of the better papers that went into it back in the day.

Probably could find others...seems 'public safety' is the sales jargon to look for.

Thanks,
