With a 5.8Ghz WLAN device, operating in the upper UNIII band, 5745mhz-5825mhz...
...is it required that if the device is using a standard 20mhz wide 802.11 channel, that you can ONLY be centered on the pre-defined frequencies of ch149/5745mhz, ch153/5765mhz, ch157/5785mhz, ch161/5805mhz, or (ISM Band) Ch165/5825?
Is it not allowed to set the center of the 20mhz wide operation channel to say, ch155/5775mhz?
I would think that as long as you are within the 5745-5825mhz, it shouldn't matter what the center frequency is.
I'm being told that with a 20mhz, you can only use those 5 pre-defined channels as their center frequency. What about devices that are capable of 10mhz and 5mhz wide channel use?
Thanks in advance.
