Does the wl127x chipsets support WLAN channel 14 usage in Japan. We are testing the Diffusivity of the 11b data rates on channel 14 (2484MHz) and observing a failure.
Diffusivity = (90% OBW)/1MHz (for 1 & 2 Mbps) = greater than 10 for 2484MHz, or greater than 5 for 2412-2472MHz
Diffusivity = (90% OBW)/1.375MHz (for 5.5 & 11 Mbps) = greater than 10 for 2484MHz, or greater than 5 for 2412-2472MHz
I measure the 90% OBW = ~9MHz for 11Mbps; Diffusivity = 6.54 and which is less than 10, therefore it fails.
How do I get a bandwidth greater than 13.75MHz, or does this chipset not support Ch14 Japan usage?
Regards,
Mike
