According to this wikipedia table, I should be able to use channel 163 @ 160 Hz. I do not see this channel as an option with my country code set to US on my RT3200.
I am interested in selecting a channel with 160 Hz width that allows for the max power of 27 dBm and that is only available on channels >=149.
I'm the advanced settings tab you can change the country code.
I have it set to US which should be supported.
Do you have any other networks/wireless devices with the country code set to a country other than the US?
Also does changing the width give you access to 163?
No, all devices are using the US code. Changing the wide from 80 to 160 has no effect on the available channels.
Your original post and Wikipedia says it's available at 160mhz. Your WiFi is 80 mhz. 163 is not available on anything less than 160Mhz according to your link.
The "channel" you set is always going to be one of the 20 MHz ones. However, wideband operation still proceeds according to the channel plan. Selecting any channel within the wide band has exactly the same on-air result. For example if you select 80 MHz channel 149, you will get an 80 MHz signal centered around "channel 155." The same thing results by selecting 153, 157, or 161. Channel 165 does not work for other than 20 since it is only in a 20 MHz channel plan.
160 MHz operation in the high end of the band requires the signal to extend down to channel 132, so the higher power allowed only on 149 and higher cannot be applied.
I see... so the max power is 24 dBm in 160 MHz width for this device. Thanks.
I do not see that. Is your device U-NII-4 certified?
Otherwise - I understand this to be the spectrum (notice no channel 163):

- DSRC/ITS (U-NII-4[8]): 5.850–5.925 GHz. At present U-NII-4 spectrum is being considered by the FCC for unlicensed use. U-NII-4 is presently only usable for Dedicated Short Range Communications Service (DSRC) and licensed amateur radio operators.
Thanks @lleachii. I am confused by the disconnects, perhaps wikipedia is incorrect.
I am wondering if an other country code offer 160 MHz at 27 dBm (ie on a high frequency) with this hardware? Reviewing the code for wireless-regdb, https://git.kernel.org/pub/scm/linux/kernel/git/sforshee/wireless-regdb.git/plain/db.txt?id=HEAD
It seems that country code ZA (South Africa) should work @ 500 mW.
