When there is no data traffic, the algorithm is driven by the short training frame (STF) SNR as
reported by each management packet. The SNR is compared to an MCS table. If the SNR is greater
or lesser than table value, the transmit power or the MCS rate is adapted accordingly.
There is a maximum TX power per MCS mode (which is defined in the configuration section).
During the adaptation process, the transmit power is either increased or decreased first to:
l
increase the power till the maximum per MCS power is reached or
l
reduce the power if there is enough headroom.
If the maximum power for the MCS mode has been reached, the MCS mode is reduced.
