5 GHz Channel Strengths

unknown

I have been trying to sort out which channels have which power, especially with regard to Ruckus gear. From what I gather:



Channels 149 and above are the strongest (1W)


Channels 100-140 are limited to 250mW


Channels below 100 are limited to 50mW.



Is the above correct? I seem to be having troubles tracking down the specifics on channel strength limitations.



Thanks,


Bob

In the USA, the FCC regulates WiFi with a maximum EIRP (combined radio xmit


power, antenna gain, minus attenuation due to cables/connectors). Ruckus AP


radios/antennas adhere to the FCC specifications.



U-NII 1 Indoor - channels 36,40,44,48


USA: 200 mW EIRP


EU: 200 mW EIRP



UNII 1 Low - channels 52,56,60,64


USA: 1 W EIRP


EU: 200 mW EIRP



UNII 2 - channels 100,104,108.112,116,120,124,128,132,136,140


USA: 1 W EIRP


EU: 1 W EIRP



UNII 3 (or ISM) - channels 149,153,157,161


USA: 4 W EIRP


EU:
