Notes on Maximum Tx Power Limitations for 5 GHz Units:
According to the Band Name being used the maximum allowed Tx Power depends
on the gain of antenna(s) and in some cases also on the bandwidth for ensuring
compliance with the maximum allowed EIRP and spectral density specified in the
relevant regulations.
The following tables show the calculated maximum transmitter power level
according to relevant FCC regulations for 5.4 and 5.8 GHz bands.
The required calculations are performed automatically by the BTS. Actual values
also take into account the maximum Tx power that can be supported by the
hardware (21 dBm) and supported resolution (calculated values are rounded
down to nearest integer).
