Independent RF power output level adjustments, for each antenna port, from +25.5
dBm to +32.5 dBm in 1-dB steps are specified in Table 6-1.
The RF power can be further reduced (independently) for each antenna port by
inserting external (fixed) attenuators between each antenna port and its associated
antenna. This method of independent port power reduction reduceS receiver
sensitivity (increasing attenuation reduces sensitivity). For any application requiring
the addition of external (fixed) attenuators, the power rating of the attenuators should
be at least twice the transmitted power.
