8.7 TX Power Control for 5 GHz Band
5 GHz power control is done via Image Creator where the maximum transmit power is provided
. Within Image
Creator, power control is possible per channel, region
. In addition, it is possible to enter
an additional back-off
factor per channel and modulation rate for further margin to regulatory requirements.
Finally, it is also possible to set the TX and RX trace losses to the antenna per band
. The peak antenna
gain
can also be provided, thus allowing further control. For a full description of options and capabilities
see the
UniFlash CC31xx, CC32xx SimpleLink™ Wi-Fi
and Internet-on-a chip™ Solution ImageCreator and
.
5
The maximum transmit power range is 18 dBm to 0.125 dBm in 0.125 dBm decrements.
6
FCC, IC/ISED, ETSI/CE, and MIC are supported.
7
Rates are grouped into high modulation rates (MCS7, 54 OFDM and 48 OFDM) and lower modulation rates (all other rates).
8
The back-off range is 0 dBm to 18 dBm in 0.125 dBm increments, with the maximum back-off not exceed that of the maximum transmit
power.
9
The range of losses if from 0 dBm to 7.75 dBm in 0.125 dBm increments.
10
The antenna gain has a range of -2 dBi to 5.75 dBi in 0.125 dBi increments.
