I am trying to verify something regarding the 802.11a power settings using a WLC:
If the power setting for the 802.11a radio is a divisor (i.e.: Power setting of "1" is full power, power setting of "2" is half power, etc.), how am I to interpret the settings that the max power setting for "lower" channels (5150 to 5250 MHz chan 36-48 FCC) is limited to a lower transmit power (i.e.: 15 dBm) than the transmit power for other "higher" channels (uni 3 from 5725 to 5850 MHz chan 149-161 FCC) which is able to transmit at 17 dBm.
Please refer to table Table 3-3 to in the following document:
In other words, what is being divided? The 15dBm or the 17dBm? Does changing the channel from a lower-numbered channel in the 5150 to 5250 MHz range to a higher-numbered channel in the 5725 to 5850 MHz range result in an increase in power (since the max transmit power is now higher)?
Or to phrase it a different way, when my power setting on the WLC is "1" for an 1131AG access point, what is my transmit power level? 15 or 17dBm? Does the power level vary - depending upon which channel I choose?
